You looked up the same house on both sites and got two different numbers. Maybe they were a few thousand apart. Maybe it was forty grand, and now you're wondering which one is lying to you.

Neither is. They're doing the same job with different data, and the gap between them tells you more than either number does on its own.

Here's the short version. On a home that's actively listed for sale, the Redfin Estimate and the Zestimate are close enough to call a tie — 1.86% and 1.9% median error, meaning half of all estimates land within about 2% of what the house actually sells for and half miss by more. On a home that isn't listed, both get noticeably worse, and Zillow pulls ahead: 7.0% against Redfin's 7.26%. On a $500,000 house, that's a swing of roughly $35,000 in either direction. Same house, same day, two honest algorithms, very different answers.

That off-market gap is where most of the confusion comes from, and it's why the "which one is more accurate" question doesn't have a single answer. It depends entirely on whether the house is on the market.

The estimates are only part of it. Redfin and Zillow are built on completely different business models — one is a brokerage that employs its agents and takes a cut of the sale, the other is an advertising marketplace that makes money selling your contact information to agents. That difference shapes everything downstream: what each one charges you, which listings you see, how fast the data updates, and who picks up the phone when you click "contact agent."

This breaks down all of it — the estimates, the fees, the listings, the filters most people never find, and which platform to use for what.

Here's how the two stack up on the things that actually change your decision.

Fees, coverage, and accuracy figures are current as of 2026 and change periodically. Confirm current terms with each company before relying on them.

Two rows deserve a closer look, because they're where the real difference lives.

The listing fee isn't 1%. Redfin advertises 1%, but that rate only applies if you also buy your next home through Redfin within 365 days of closing your sale. Sell without buying and it's 2%. Market minimums also override the percentage on lower-priced homes, and if your buyer shows up without an agent, Redfin's fee goes up by 1%.

Zillow, by contrast, charges sellers nothing to list. It isn't a brokerage and doesn't take a cut of your sale. It makes money selling leads to agents. Which brings us to the row that matters most.

Who gets your contact information. Click "contact agent" on Redfin and you reach a Redfin employee — salaried, working for the company that runs the site. Click the equivalent on Zillow and your details typically go to an agent who paid to advertise in that ZIP code. That agent may be excellent. They may also simply be the one who bought the placement.

Neither model is inherently better. A salaried agent has no commission incentive to push you toward a pricier house, but they're also handling volume for a company optimizing throughput. A Zillow-referred agent runs their own business and may give you far more individual attention — or may be juggling leads from three portals. What matters is knowing which one you're getting, because the buttons look identical.

On listing counts. You'll see wildly different numbers quoted for how many listings each platform has, usually because two different things are being conflated. Zillow's database covers 100+ million homes — every property it tracks, most of which aren't for sale. Actively listed homes nationwide run in the low millions at any given time, and both platforms pull from the same MLS feeds, so for-sale inventory overlaps heavily.

The real gaps are narrower. Zillow accepts listings directly from homeowners; Redfin doesn't, though it does display FSBO listings pulled from FSBO.com and Fizber.com, which typically appear about a day after you post there. Redfin only operates in markets where it has MLS access, so rural and smaller markets can come up thin. In a major metro, you'll see substantially the same houses on both.

What Is Redfin?

The important thing about Redfin is that it's a brokerage first and a website second.

That distinction drives everything else. Because Redfin employs licensed agents and participates in local MLS databases, it has direct access to listing data rather than receiving a syndicated feed. That's why its listings and estimates update daily on active properties, and why it only operates in the 80-plus markets where it has that access.

It also means Redfin makes money the way brokerages do — by taking a cut of transactions. Its 2% listing fee, dropping to 1% if you also buy through Redfin within a year, is roughly half what a traditional listing agent charges. The company covers the gap with volume and technology rather than by charging more per deal.

Rocket Companies completed its acquisition of Redfin on July 1, 2025, in an all-stock transaction valued at about $1.75 billion. Rocket is the parent of Rocket Mortgage, one of the largest mortgage lenders in the country, and the strategic logic was to connect home search directly to financing. Redfin now operates under the brand identity Redfin Powered by Rocket.

The practical changes for users are concrete. Redfin's mortgage lending now runs through Rocket Mortgage rather than Bay Equity, the affiliate it used previously. And the companies introduced Rocket Preferred Pricing, which offers buyers who use a Redfin agent and finance through Rocket Mortgage either a one-percentage-point interest rate reduction for the first year or up to $6,000 in lender credits.

What Redfin is best at: fresh data, lower listing fees, and search filters built for people looking at properties analytically rather than emotionally. What it isn't: comprehensive. If you're searching a rural county or looking for owner-listed homes, Redfin may simply not have them.

What Is Zillow?

Zillow doesn't sell houses. It sells access to the people looking at them.

That's not a criticism — it's the business model, and understanding it explains most of what Zillow does. The company operates the most-visited real estate platform in the United States, with roughly 220 million average monthly unique users across Zillow, Trulia, StreetEasy, and HotPads, and about 2.3 billion visits in the first quarter of 2026. That audience is the product. Agents pay for placement through the Premier Agent program, and lenders, property managers, and builders advertise alongside them.

Because it isn't a brokerage, Zillow has no MLS access of its own and no agents of its own. It aggregates listing feeds, public records, and tax assessments, then layers on information homeowners submit directly. That's how it covers all 50 states, and it's why Zillow shows properties in markets Redfin never entered.

It also accepts listings straight from homeowners, free, which is why Zillow is the default for anyone selling without an agent.

Zillow is no longer in the home-buying business. It shut down Zillow Offers, its iBuying operation, after announcing the wind-down in 2021. The company has since focused on what it calls a housing super app — an integrated experience spanning search, touring, financing through Zillow Home Loans, and closing. Its portfolio includes ShowingTime for tour scheduling, Follow Up Boss for agent CRM, and Zillow Closing. Jeremy Wacksman has served as CEO since 2024.

What Zillow is best at: breadth. More markets, more listings, more property types, and a database covering well over 100 million homes whether they're for sale or not. What to keep in mind: it's an advertising platform, so the agent who responds when you click "contact" is the one who bought that placement, not necessarily the best agent in the area.

Is Redfin or Zillow More Accurate?

Figures published by Redfin and Zillow, current as of 2026. Both companies revise them periodically — check their accuracy pages for the latest.

There's no single winner, and any article that gives you one is oversimplifying. Redfin edges Zillow on listed homes by four hundredths of a percentage point, which is close enough to call a tie. Zillow is genuinely better on homes that aren't for sale, by about a quarter of a point.

What "median error" actually means. This is the part that gets skipped, and it matters more than the numbers themselves. A 1.86% median error doesn't mean the estimate is within 1.86% of the sale price. It means half of estimates land within 1.86% — and the other half miss by more, sometimes far more. It's a midpoint, not a ceiling.

Run the off-market figures through a real house. On a $500,000 home, Zillow's 7.0% is a $35,000 spread and Redfin's 7.26% is about $36,300. Half the time it's worse than that. That's not a rounding difference on a home sale — it's the gap between a deal and a mistake.

The national numbers hide a lot. Both companies publish accuracy by metro area, and the spread between markets is much wider than the spread between companies. Dense suburbs where houses are similar and sales are frequent produce tight estimates. Rural areas, unusual properties, and markets with few recent sales produce much worse ones. Your local error rate may look nothing like the national median.

What A Professional Actually Does With These Numbers

Ryan Zomorodi, co-founder of Real Estate Skills, has bought and wholesaled property in more than a dozen states. His position on automated estimates is blunt: he doesn't price deals with them.

That's the honest answer to "which estimate is more accurate." Both are close on listed homes. Neither is what someone pricing a real transaction relies on.

But he does use one of these tools — and the reason is the point. For rental income he'll pull up a rent estimate on either platform for a quick read, and he specifically favors Zillow's, because it shows you the underlying rental comps rather than just handing you a number. That lets you check the work and adjust rather than accept it on faith.

That's the whole principle in one line: trust the tool that shows you its comps. It's why the Zestimate and the Redfin Estimate are fine as starting points and poor as conclusions — neither shows you what it used to get there.

When Is An Online Estimate Good Enough?

When nothing is riding on it.

Curious what your house is worth? Either one is fine. Watching a neighborhood casually? Fine. Getting a rough sense of whether you have enough equity to refinance? Reasonable starting point.

But when you're setting a list price, making an offer, or deciding whether a deal works, the estimate isn't the answer. It's the thing you check before doing the actual work. A comparative market analysis from a licensed agent is free and takes a day. An appraisal costs a few hundred dollars and is what a lender will rely on regardless of what either website says.

This is educational information, not an appraisal or professional valuation. Home values vary by market and property condition. Confirm any figure with a licensed real estate agent or appraiser before making a financial decision.

The Estimate Is A Starting Point. This Is How You Find The Real Number.

Both Redfin and Zillow tell you their estimates can miss by 7% on a home that isn't listed — roughly $35,000 on a $500,000 house. The way professionals close that gap is by pulling their own comparable sales, and there's a specific set of criteria for choosing which ones actually count.

Why Are Redfin And Zillow Estimates So Different?

The single biggest reason comes down to one question: is the house currently for sale?

When a home is listed, both companies are working from the same MLS entry — the agent-maintained database where properties get listed for sale. That entry spells out square footage, bed and bath count, condition, recent updates, and photos. Both algorithms get fed real, current, agent-verified detail, and both land within roughly 2% of the eventual sale price.

When a home isn't listed, all of that disappears. Now both companies are working from tax records, old sales data, and whatever the owner has told them. Median error jumps to 7.0% for Zillow and 7.26% for Redfin. On a $500,000 house that's a $35,000 swing — and remember, "median" means half of all estimates miss by more than that.

So if you're looking at two wildly different numbers on a house that isn't for sale, you're not seeing a malfunction. You're seeing two algorithms guessing with thin information, and guessing differently.

They're pulling from different places. Redfin is a brokerage, which means it has direct access to MLS databases and builds its estimate primarily from that feed — over 500 data points per property, covering about 92 million homes. Zillow isn't a brokerage. It aggregates MLS feeds, public records, and tax assessments, then layers on data submitted by homeowners themselves, and publishes Zestimates for more than 100 million homes. Broader coverage, more mixed sourcing.

That's why you'll sometimes find a Zestimate on a rural or unusual property where Redfin shows nothing at all.

They refresh on different clocks. Redfin updates daily for listed homes and weekly for everything else. If a listing's price dropped yesterday, one platform may have absorbed it and the other may not have yet. Check the same house on a Tuesday and a Friday and the gap between them can change on its own.

Neither one can see inside the house. This is the part that trips up homeowners. If you gutted the kitchen and added a bathroom and never pulled a permit that hit public record, no algorithm knows. Zillow lets you update your home's facts directly, which is why an owner-updated Zestimate sometimes runs higher than a Redfin Estimate on the same property — one has the renovation, the other doesn't.

And in some states, the sale prices aren't even public. Texas is a non-disclosure state, meaning what a house actually sold for never becomes a public record. Ryan Zomorodi ran into this reviewing a Houston listing with almost no price history showing: the data simply isn't published there. Automated estimates in non-disclosure states are working with a real blind spot, and both platforms are less reliable as a result.

So which one runs higher? There's no consistent answer, and anyone who tells you otherwise is guessing. It flips property to property depending on which platform has better data on that specific house. Redfin is stronger where MLS data is rich and recent. Zillow is stronger where a homeowner has filled in the gaps or where Redfin has thin coverage.

What to do when they disagree. Treat the spread as information. Two estimates $5,000 apart on a listed home means both algorithms have good data and agree — that's a usable ballpark. Two estimates $40,000 apart on an unlisted home means neither knows much, and the honest answer is that nobody can tell you what that house is worth from a screen.

At that point you need actual sold comparables — recently sold homes nearby, similar in size and age — or a licensed agent's comparative market analysis. Both are free to get. Neither takes long.

 Redfin vs. Zillow: Fees & Commissions

Redfin advertises a 1% listing fee. Most sellers pay 2%.

The 1% rate applies only if you also buy your next home through Redfin within 365 days of closing on your sale. The mechanics are worth understanding: Redfin charges the full 2% at closing, then sends you a check for the 1% difference after your next purchase closes. If you sell and don't buy — or buy elsewhere, or buy after the year is up — you paid 2%.

The order matters. If you buy through Redfin first and then sell, you pay the 1% listing fee directly. If you sell first, Redfin charges the full rate at closing and refunds the difference after your next purchase closes.

Two more conditions sit underneath that.

Market minimums override the percentage. Redfin sets a minimum commission that varies by market, and whichever is larger — the percentage or the minimum — applies. On a lower-priced home that minimum can push your effective rate above 2%. Redfin publishes the current minimum for each market on its commission disclaimer page, and it's worth checking yours before you assume the percentage is what you'll pay.

An unrepresented buyer costs you more. If your buyer arrives without an agent, Redfin's listing fee increases by 1% of the sale price. That's counterintuitive — no second agent, higher fee — and it's in Redfin's own disclosure.

Redfin also notes the 1% rate isn't available in every market.

Zillow charges sellers nothing. It isn't a brokerage and takes no cut of your sale. You can list a home there for free, including for sale by owner. Zillow's revenue comes from selling leads to agents who advertise on the platform, plus its mortgage and rentals businesses. If you sell through an agent you found on Zillow, you pay that agent's commission — negotiated with them, not with Zillow.

What You'll Actually Pay To Sell

This is where most comparisons go wrong.

For years, articles described a "standard 3% buyer's agent commission" paid by the seller. That framing is no longer accurate. Following the National Association of Realtors settlement, practice changes took effect on August 17, 2024: offers of buyer-agent compensation were removed from MLS listings, and buyers must now sign a written representation agreement with their agent before touring homes.

Compensation didn't disappear. It moved off the MLS and became an explicit negotiation. Sellers still commonly agree to cover some or all of a buyer's agent fee — it's frequently offered as a concession in the purchase contract — but it's negotiated per transaction rather than posted in advance. Redfin says as much in its own seller FAQ: you aren't required to offer any buyer's agent compensation, many sellers choose to, and the amount is always negotiable and ultimately the seller's decision.

So the honest math looks like this. With Redfin, your listing side is 2% (or 1% if you also buy with them), subject to minimums. Whatever you agree to contribute toward the buyer's agent is separate and negotiable. Redfin's own example uses a 2.5% buyer's agent fee, which would put a typical seller around 4.5% total — against a traditional 5% to 6% when both agents charge 2.5% to 3%.

With Zillow, there's no listing fee at all, but you're paying whatever your agent charges. List for sale by owner and you pay no listing-side commission — though you may still negotiate a buyer's agent fee to attract represented buyers, and you're doing the work an agent would otherwise do.

The savings are real but smaller than the headline. Redfin's discount applies to the listing side only, which is roughly half the total. A 1-point saving on the listing side of a $400,000 sale is $4,000 — meaningful, not transformative. And every commission in the transaction is negotiable, including with a traditional agent. The settlement made that explicit: broker fees are not set by law.

This is educational information, not financial or legal advice. Commission structures vary by market and are negotiable. Confirm current terms directly with any brokerage and consult a licensed professional before signing a listing agreement.

Search Tools & Filters: Which Platform Finds More

Most people use maybe a fifth of what these platforms can do. The filters below the fold are where the two genuinely diverge, and they're the reason investors tend to keep both open.

Redfin has a dedicated fixer-upper filter. Under Home Features there's a checkbox that surfaces properties Redfin's algorithm classifies as needing work — it reads the listing language, the photos, and whether the agent flagged it as a fixer. Alex Martinez uses it as a first pass in unfamiliar markets: check the box, and a county-wide search collapses to the distressed inventory in seconds. In one Riverside County search it returned 94 properties.

Zillow's own guidance points to a different route for the same goal: keyword search. Type "fixer upper," "needs work," or "TLC" into the keywords field and you'll surface comparable listings. The mechanism differs — keyword search matches text in the description, so it catches what agents happened to write and misses what they didn't.

Neither approach is complete. Ryan Zomorodi is direct about the tradeoff: Redfin's filter leaves out plenty of good opportunities, and it's a quick sweep rather than a thorough search. But as a way to see a market's distressed inventory in under a minute, it's the fastest thing either platform offers.

Price-per-square-foot sorting is the underrated one. Switch Redfin to table view — one of four layout options — and you can sort every listing by dollar per square foot, which is just asking price divided by living area. Sort ascending and the cheapest inventory in the market surfaces immediately.

What makes this more than a sorting trick is what it's measuring. When price per square foot drops below what it would cost to build the same structure, you're buying below replacement cost, which is a genuine valuation signal rather than a bargain-hunting instinct. In a recent Chattanooga search the lowest listing came in at $56 per square foot — well under construction cost in that market.

Keyword search works on both, and the vocabulary matters more than the platform. Both let you search listing descriptions. The terms that surface investor-oriented listings are consistent: as-is, motivated, fixer, TLC, investor, contractor special, cash, value-add, handyman special. Different words return different sets, so it pays to run several rather than settle on one.

One caution worth carrying over: keyword fields on these platforms match loosely. Zillow's has been documented returning listings where the matched phrase appears in an unrelated context. Read what comes back rather than trusting the filter count.

Foreclosures: Zillow's filter is more granular. Both platforms filter for foreclosures. Zillow's listing-type menu separates pre-foreclosures, auctions, and bank-owned properties, which matters because those are three different transactions — an auction typically requires cash and often can't be insured for title, while a bank-owned listing is a conventional purchase from a lender that wants it off the books. Redfin's is a single foreclosure toggle.

Volume differs by market and by platform. A recent search returned 216 foreclosure results in Houston on Zillow, 44 in Birmingham on Realtor.com, and 9 in Chattanooga on Redfin — though Redfin's count climbed to 22 after removing the drawn map boundary, which is a mechanic worth knowing. If a Redfin search looks thin, the outline may be cutting it off.

Where the listing agent's contact information sits. On the MLS itself, the listing agent's email and brokerage phone are always there. On Redfin, Zillow, or Realtor.com, the phone number is sometimes shown and sometimes not — often you get the agent's name and brokerage and have to look them up. Minor friction, but it's real, and it's why people working deals seriously tend to want MLS access rather than relying on portals alone.

Inventory neither platform reliably shows. Government-held foreclosures are a genuine blind spot. HUD Home Store lists properties foreclosed from FHA loans, and Fannie Mae's HomePath lists properties from conventional loans. Neither reliably appears on Redfin or Zillow. If you're specifically hunting distressed inventory, those are separate sites worth checking directly.

Does One Platform Show More Listings Than The Other?

The assumption behind this question is usually that one platform is hiding something. In most markets, that's not what's happening — both are pulling from the same underlying source.

That source is the MLS. There are more than 600 of them across the country, each a database maintained by real estate professionals covering a county or region. Agents list properties there first, and the portals pull from those feeds. So when you search a major metro on both sites, you're largely looking at the same houses through two different interfaces.

The differences sit at the edges, and there are three of them.

Coverage. Redfin operates in 80-plus markets, and only where it has MLS access, because it's a brokerage that needs that access to function. Zillow aggregates feeds nationwide. In a large metro, that difference is invisible. In a rural county or a smaller market, Redfin may show noticeably less — or nothing.

For sale by owner. Zillow accepts listings directly from homeowners, free. Redfin has no direct owner-upload path, though it does pull FSBO listings from FSBO.com and Fizber.com. If you're searching for owner-listed properties, or you're an owner trying to list one, that's a hard distinction rather than a preference.

And then there's inventory that's deliberately kept off the portals. This is the interesting one, and it's been the subject of a two-year fight.

The Private Listings Fight, And Why It Matters To A Buyer

Some brokerages market homes inside their own agent networks before listing them publicly. The industry calls these private exclusives or office exclusives. Sellers sometimes want the privacy; brokerages get their own clients a first look.

Zillow blocks certain listings. Redfin now displays them. That's the clearest inventory difference between the two platforms today, and it's recent.

In April 2025, Zillow announced Listing Access Standards: a home publicly marketed without being submitted to the MLS within one business day would not be published on Zillow. Redfin said it would follow suit. Compass — the largest brokerage in the country and the one most invested in private exclusives — sued Zillow in June 2025 on antitrust grounds. In February 2026 a federal judge declined to block Zillow's policy, finding Compass hadn't shown Zillow held the power to exclude competition from online home search.

Then the ground shifted. On February 26, 2026, Rocket Companies and Compass announced a three-year strategic alliance. Compass "Coming Soon" listings began appearing on Redfin immediately, with Private Exclusives to follow — potentially more than 500,000 additional listings, across Compass brands including @properties, Better Homes and Gardens Real Estate, CENTURY 21, and Christie's International. Days later, Compass dropped its suit against Zillow, which had relaxed its standards and launched Zillow Preview for pre-market listings.

What this means practically. If you're searching a market where Compass or its brands are strong, Redfin may show you homes Zillow won't — pre-market inventory that hasn't hit the MLS yet.

There's a real tradeoff, and it's worth understanding before you rely on it. Compass listings syndicated to Redfin appear without days on market, without price history, and without a Redfin Estimate. You're seeing the house stripped of the context you'd normally use to judge it — how long it's been sitting, whether the price has moved, what the algorithm thinks it's worth. And inquiries on those listings route to the Compass listing agent rather than a buyer's agent.

That's a genuine expansion of visible inventory and a genuine reduction in visible information, at the same time.

There's also no filter that surfaces everything. The way people who work deals get early access is relationships — staying in regular contact with listing agents who work their target property type. Both Alex and Ryan describe the same pattern: call enough listing agents consistently and you eventually hear about properties before they're published anywhere. That's slower than a search filter, and it's the honest answer. If you want to see everything in a market, no portal gets you there by itself.

Redfin vs. Zillow For Rentals

If you're comparing the two for apartment hunting, there's something you should know first: you're largely looking at the same inventory.

Zillow supplies Redfin's apartment listings. In February 2025, Zillow paid Redfin $100 million to become the exclusive provider of multifamily rental listings — buildings with 25 or more units — across Redfin, Rent.com, and ApartmentGuide. Redfin exited the apartment-listing business as part of the deal and handed its customer relationships to Zillow.

The arrangement drew an antitrust challenge. The Federal Trade Commission and five state attorneys general sued both companies in September 2025, arguing the deal removed an independent competitor from an already concentrated market. A trial was set for August 2026, and on August 24, 2026, the parties announced a resolution: the syndication partnership continues through at least 2030, Redfin keeps the $100 million, and beginning in 2027 both companies will also offer standalone multifamily advertising products. The order is subject to court approval, so the details may shift.

The practical upshot for a renter is simple. On large apartment buildings, comparing Redfin against Zillow is mostly comparing two interfaces onto the same listings. Pick whichever you find easier to use. For single-family rentals and smaller properties the inventories still differ, so it's worth checking both.

Rent Estimates: The One Place Zillow Clearly Wins

Both platforms will estimate what a property should rent for. Zillow's is the Rent Zestimate; Redfin's is the Rental Estimate. Punch in an address on either and you get a monthly figure in seconds.

The difference is what happens after the number appears.

Zillow shows you the rental comparables behind its estimate — the nearby properties it used, their sizes, what they're asking. Redfin hands you the figure. Ryan Zomorodi uses both for quick reads and prefers Zillow's for exactly this reason: seeing the comps lets you sanity-check the number and adjust it, rather than accepting it on faith.

That's the same principle that governs the sale-price estimates. A tool that shows its work is more useful than a tool that's slightly more confident, because you can tell when it's wrong.

How A Professional Estimates Rent

Ryan doesn't rely on either tool for a decision. He runs his own rental comps, and the method is straightforward enough to copy.

Pull up active rental listings in the immediate area — not sold data, current asking rents. Filter to properties similar in size, bed and bath count, and condition. Then pay attention to how many there are and how long they've been sitting. That last part is what an automated estimate can't tell you: a number means one thing in a market where units lease in a week and something very different where they sit for two months. Volume and speed tell you whether the asking rents are real.

A quick example of why the check matters. Running numbers on a distressed Chattanooga property, Redfin's tool returned roughly $1,876 a month. That's a usable starting figure — but it's a starting figure. Whether the property actually achieves it depends on the finished condition, the specific block, and how much competing inventory is on the market when it's ready to lease. Outcomes vary, and no algorithm is pricing in a renovation that hasn't happened yet.

This is educational information, not financial advice. Rental income projections vary by market and property condition; confirm figures with local data and a licensed professional before making an investment decision.

What Happens When You Click "Contact Agent"

This is the clearest practical difference between the two, and almost nobody explains it before you click.

Redfin is a brokerage with roughly 2,200 of its own agents. Contact them about a listing and you're routed to a Redfin employee — salaried, on the company payroll, working within Redfin's system. Your information stays inside the company handling your transaction.

Zillow isn't a brokerage and has no agents. Its Premier Agent program sells advertising placement to agents by area, so when you submit an inquiry, your contact details are typically routed to whichever agent or agents purchased that placement. Zillow's business model is built on this: the lead is the product.

Neither is inherently better, and that's worth saying plainly.

A salaried Redfin agent has no commission incentive pushing you toward a more expensive house. They're also handling volume for a company optimizing throughput, which can mean less individual attention. A Zillow-referred agent runs their own business and may give you far more personal service — or may be working leads from three portals at once. The agent who bought your ZIP code isn't necessarily the best agent in it; they're the one who paid.

What matters is knowing which you're getting. If you want a specific agent, contact them directly rather than through a portal button — that removes the routing question entirely.

On data collection generally: both companies collect substantial information about how you use their platforms — searches, saved homes, browsing behavior — and both publish privacy policies detailing it. Neither is unusual for a large consumer platform. Zillow's model does mean your contact information is more likely to be shared with third parties, because that sharing is the service being sold to advertisers. If that matters to you, it's a reason to browse without submitting a form until you've chosen an agent yourself.

Which Should You Use? Redfin vs. Zillow By Situation

If you're buying. Start on Zillow for breadth. It covers all 50 states, carries owner-listed properties Redfin doesn't, and in rural or smaller markets it may be the only one with meaningful inventory. In a major metro, both show substantially the same listings, so the choice comes down to which interface you prefer.

Redfin's advantage is data freshness. As a brokerage with direct MLS access, its listing status and estimates update daily on active properties. That matters most in fast markets, where the difference between a listing marked active and one already under contract is a wasted phone call.

Practical approach: search on both, and when you find something, contact the listing agent directly rather than through either platform's button.

If you're selling with an agent. Redfin is the cheaper listing side — 2%, or 1% if you also buy through them, against a traditional 2.5% to 3%. On a $400,000 sale that's real money, though the saving is smaller than the headline because it applies to the listing side only and market minimums can erode it on lower-priced homes.

The tradeoff is the service model. Redfin agents work more transactions than a typical traditional agent, which is how the lower fee is possible. Some sellers find that efficient. Others want someone with more time for their specific sale. Neither reaction is wrong.

Your listing will appear on both platforms regardless — MLS listings syndicate widely — so this isn't a question of exposure. It's a question of who represents you and what they charge.

If you're selling for sale by owner. Zillow, without much debate. You can list directly, free, with unlimited photos. Redfin has no owner-upload path, though it does display FSBO listings pulled from FSBO.com and Fizber.com — so you can reach its audience indirectly, but those sites charge a fee, and a home on the MLS will override the FSBO version.

One caveat: Zillow separates owner-listed homes from agent listings in search results, so a buyer who doesn't specifically look for them may never see yours. That's the real cost of FSBO on Zillow — not the listing, the visibility.

If you're running comps or estimating value. Use both, and treat the gap between them as information rather than noise. Two estimates close together on a listed home means both algorithms have good data. Two estimates far apart on an unlisted home means neither knows much.

For anything with money riding on it, neither number is the answer. Pull actual sold comparables or get a comparative market analysis from a licensed agent — both are free.

If you're an investor or looking for distressed property. Redfin's fixer-upper filter and price-per-square-foot table sorting have no direct equivalent on Zillow. Zillow's foreclosure filter is more granular, separating pre-foreclosure, auction, and bank-owned. Most people wholesaling real estate or getting started as a real estate investor use both, plus Realtor.com, plus the government foreclosure sites neither portal reliably carries.

If you're renting. On large apartment buildings you're looking at the same listings either way — Zillow supplies Redfin's multifamily inventory. For single-family rentals and smaller properties, check both. For rent estimates, Zillow's shows you the comps.

A Note On Realtor.com

Plenty of people comparing these two are really choosing among three.

Realtor.com is a marketplace rather than a brokerage, pulling directly from MLS feeds, which historically gave it a reputation for listing accuracy. Like Zillow, it sells leads to advertising agents. Like both, it has a foreclosure filter and keyword search.

For most searches it's a third window onto the same inventory. It's worth having open if you're working a market seriously, and it's not worth agonizing over if you're not.

Redfin vs. Zillow: Frequently Asked Questions

Final Thoughts: Is Redfin Better Than Zillow?

No, Redfin isn't better than Zillow. Zillow isn't better than Redfin either. They're different products that happen to look alike.

Zillow is an advertising marketplace. It shows you the most homes, in the most places, including ones owners listed themselves, and it makes its money selling your attention to agents. Redfin is a brokerage that runs a search site. It shows you fewer markets with fresher data, employs the agent who answers, and charges less to sell your house because it wants the transaction.

Once you see that, the choice stops being about which site is better and starts being about what you're doing.

• Best for browsing: Zillow. More markets, more listings, FSBO inventory Redfin doesn't carry.
• Best for selling with an agent: Redfin. A 2% listing fee against a traditional 2.5% to 3%, with the caveat that market minimums can erode the saving on lower-priced homes.
• Best for selling FSBO: Zillow. It's the only one of the two that lets you list your own home directly.
• Best for fresh listing data: Redfin. Direct MLS access, daily updates on active listings.
• Best for estimating an off-market home: Zillow. 7.0% median error against Redfin's 7.26% — closer than most people assume, but Zillow does win it.
• Best for investors hunting distressed property: Both, honestly. Redfin's fixer-upper filter and price-per-square-foot sorting, Zillow's more granular foreclosure filter.
• Best for renters: Either for apartments — you're seeing the same listings. Zillow for rent estimates, because it shows you the comps.

The Thing Worth Remembering

Both companies publish a number next to a house and both are honest about how often it's wrong. On a listed home they're within four hundredths of a point of each other. On an unlisted home either can miss by $35,000 on a $500,000 house — and that's the median, meaning half the time it's worse.

The people who do this professionally treat both numbers the same way: as a place to start, never as an answer. When there's money on the line, they pull actual sold comparables — recent, nearby, similar — or get a comparative market analysis from a licensed agent. Both take a day and cost nothing.

That's not a knock on either company. It's what these tools are for. An algorithm that can't see inside your kitchen is giving you a starting point, and a starting point is genuinely useful right up until the moment you mistake it for a valuation.

What to do next. Open the address on both sites. If the two estimates are close and the home is listed, you have a reasonable working number. If they're far apart, or the home isn't on the market, you don't have a number yet — you have a question, and the answer is in the sold comps down the street.
