Quick Summary
- Zillow Preview lets participating brokerages pre-market coming-soon listings publicly on Zillow and Trulia before they go active in the MLS.
- If a buyer uses the "Request a Tour" button on a Preview listing and later closes with a Zillow Preferred agent, the listing agent receives a referral fee equal to 10% of the buyer's agent commission, paid through their brokerage.
- The fee is paid by Zillow out of its own take. It does not reduce commissions for the consumer or the Preferred buyer agent's net.
- Access is broker-gated. Individual agents cannot opt in directly. The program launched with Keller Williams, RE/MAX, HomeServices of America, Side, and United Real Estate, with 24 additional brokerages added within a week.
- Controversy: the "Request a Tour" button still routes to a Zillow Preferred buyer agent, not the listing agent. Critics and an active class-action lawsuit argue consumers do not understand the routing.
For the first time, Zillow is offering listing agents a cut of buyer-side revenue generated on their own listings. The mechanism sits inside the new Zillow Preview program, announced in March 2026 and already adopted by more than two dozen brokerages. This guide breaks down exactly how the money flows, where the controversy lives, and how to model the upside for your own listing pipeline.
What Actually Changed in March 2026
On March 17, 2026, Zillow Group publicly launched Zillow Preview℠, a new product category sitting between an MLS listing and a traditional coming-soon tag. It lets brokerages market a seller's home publicly on Zillow and Trulia during a pre-active window, while still complying with local MLS clear cooperation rules. Listings carry the brokerage's branding and show live engagement data: views, saves, shares, and tour requests.
The launch came three weeks after Compass and Redfin announced a competing pre-marketing partnership that moves Compass's private listings onto Redfin's site. Zillow Preview is the public, multi-brokerage counterpunch to that deal, and the referral fee to listing agents is the incentive Zillow is using to win brokerages away from private listing networks.
The piece that changes agent economics is buried in the fine print of Zillow's press release: when a qualified Preview connection closes through Zillow's Preferred agent network, the listing agent may receive a share of what Zillow earns on the transaction. Errol Samuelson, Zillow's Chief Industry Development Officer, told HousingWire the specific share is 10% of the buyer's agent commission, paid through the listing agent's brokerage.
For listing agents, that is a structural first. Zillow has paid buyer-side referral fees to Flex and Premier agents for years. Paying the seller-side listing agent for a buyer-side close on their listing, without costing the seller or the buyer anything extra, is new.

Get Matched With a Top AgentZillow Preview vs. Premier Agent vs. Flex vs. Preferred: A Quick Glossary
Zillow has layered multiple programs on top of each other over the past decade, and the names keep changing. Here is the clean version of what each one actually does in 2026. For a deeper breakdown of how gross commissions are typically split before any referral fees are deducted, see our guide on how much realtors charge.
| Program | Who Pays Zillow | How It Works | Typical Fee |
|---|---|---|---|
| Zillow Premier Agent | Agent (monthly ad spend) | Pay-for-share-of-voice advertising model. Agents buy a percentage of zip code lead volume; leads are routed to whichever Premier Agent is next in rotation. | Variable monthly spend by ZIP |
| Zillow Flex / Zillow Preferred | Agent (success fee at close) | Invitation-only, pay-at-close model. Zillow routes concierge-screened buyer leads to vetted agents. No upfront cost, but Zillow takes a percentage of gross commission income on every closing. | 15 to 40% of GCI |
| Zillow Preview | Nobody (for now) | Pre-market listing distribution. Brokerages pre-market coming-soon listings on Zillow/Trulia. Listing agents keep their full listing commission and receive a 10% referral on buyer-side commission if the buyer closes through a Preferred agent. | Listing agent earns 10% of buyer commission |

The important frame: Premier Agent and Flex are programs where the agent pays Zillow. Preview is the first Zillow program where Zillow pays the agent (specifically, the listing agent) on the buyer side of a transaction. That inverts the cash-flow direction of the portal-to-agent relationship, at least on this one narrow lane.
How Lead Routing Actually Works on a Preview Listing
Every Zillow Preview listing displays two primary buttons. The difference between them is where all the money in this model hinges.
Contact Agent
Routes the buyer directly to the listing agent. No referral fee is owed on leads generated through this button during the preview window. This is the "free lead" path for the listing agent.
Request a Tour / Schedule a Tour
Routes the buyer to a Zillow Preferred buyer agent, who may be anywhere in the zip code's rotation. If that buyer later closes on any home with that Preferred agent, the listing agent on the original Preview listing receives the 10% referral share, paid through their brokerage.
Most buyers do not understand which button does what
This is the core of a class-action lawsuit filed in September 2025 by Hagens Berman in the U.S. District Court for the Western District of Washington. The complaint alleges that Zillow's interface leads consumers to believe "Request a Tour" connects them with the listing agent, when in fact the lead is routed to a Flex/Preferred buyer agent who pays Zillow up to 40% of their commission. The suit argues that arrangement violates RESPA and Washington consumer protection law. Zillow disputes the allegations.
Zillow's framing is that Preview gives the listing agent two bites at the apple: a free direct-contact lane through "Contact Agent," and a revenue-share lane through "Request a Tour." Critics argue the second bite is table scraps of a commission that should have gone to the listing agent in the first place, and that the program normalizes the lead-interception mechanic rather than fixing it.
The Referral Fee Math: What Listing Agents Actually Earn
Let's walk through the economics on a concrete example. Assume a median-priced home in a typical market.
That $1,062 is paid by Zillow, through the listing agent's brokerage, on top of whatever the listing agent already earned on the seller side of the same transaction. On a $1M listing with a 2.5% buyer agent commission, the listing agent's referral fee is $2,500 per buyer who clicks "Request a Tour" and closes through a Preferred agent.
The revenue path, step by step:
- Buyer clicks "Request a Tour" on the Preview listing.
- Zillow routes the buyer to a Preferred buyer agent in the relevant zip code.
- That Preferred agent shows the buyer homes, eventually closing on one (not necessarily the Preview listing that generated the click).
- At close, the Preferred buyer agent owes Zillow a Success Fee on their gross commission income. Industry estimates put this at 15% to 40%, with 35% being typical.
- Zillow pays out 10% of the buyer's agent commission to the original listing agent's brokerage, which then forwards it to the listing agent per their split.
Net: if you assume a 35% Flex take on a $10,625 commission, Zillow grosses about $3,719 on the referral. It then pays the listing agent $1,062 out of that. Zillow nets roughly $2,657, the buyer agent nets $6,906 before their own brokerage split, the listing agent earns an incremental $1,062 they would not otherwise have seen, and the consumer's total transaction cost is unchanged.
The incentive shift is the point, not the dollar amount
The per-listing dollar is modest. The strategic shift is that listing agents now have a financial reason to want their listings posted publicly on Zillow during the pre-active window, rather than in a private brokerage network. That is exactly the behavior Zillow is trying to buy, and it is directly aimed at Compass's private listing strategy.

Which Brokerages Have Signed On
Access to Zillow Preview is gated at the brokerage level. Individual agents cannot opt in on their own; their brokerage has to have a partnership agreement with Zillow. The adoption curve in the first month has been steep.
Initial launch partners (March 17, 2026)
- Keller Williams
- RE/MAX
- HomeServices of America (including Berkshire Hathaway HomeServices brands)
- Side
- United Real Estate
Added in the first week (March 25, 2026)
Zillow announced 24 additional brokerages and franchisors, including Berkshire Hathaway HomeServices, Engel & Völkers Americas, SERHANT., and Samson Properties. Zillow also said more than 800 additional brokerages had expressed interest. By mid-April, independent brokerages like FirstTeam in California were continuing to sign on.
What this means for agents at non-participating brokerages
If your brokerage is not a Preview partner, you cannot currently post a Preview listing or collect the 10% referral. You can still list on Zillow the traditional way via the MLS feed. The question to raise with your broker is whether, and when, your firm plans to evaluate joining, because the competitive dynamic on the listing side is already shifting.
The Controversy: Lead Interception and Consumer Disclosure
Zillow Preview arrived into an already-heated debate about how online portals route buyer leads and how much of a commission those portals capture without disclosing it. Three pressure points matter for agents trying to evaluate this program.
The lead-interception argument
The core critique from brokers and industry commentators (including Robbie English, Jon Brooks, and others in the broker community) is that the "Request a Tour" button on any Zillow listing, Preview or otherwise, routes the consumer away from the listing agent even though the listing agent is the person the consumer is looking at on the page. A 10% kickback to the listing agent, critics argue, is a palliative for a routing problem that should not exist.
The RESPA class-action lawsuit
In September 2025, law firms Hagens Berman and others filed a class-action complaint against Zillow Group in federal court in Seattle. The suit alleges that Zillow's Flex/Preferred program inflates buyer costs by funneling undisclosed referral fees (up to 40% of commission) to Zillow, in violation of the Real Estate Settlement Procedures Act and Washington consumer protection statute. The case is still pending. Zillow has disputed the allegations and continues to operate the program.
The Consumer Policy Center report
In February 2026, the Consumer Policy Center released a report arguing that referral fees in the 30 to 40 percent range keep overall commission rates high because receiving agents have less incentive to negotiate down when a large slice of their income is pre-committed to the referrer. The CPC report named Zillow as the largest single referral player, citing more than 1.4 million buyer connections through the Premier/Preferred network. Zillow disputed the CPC's methodology.

See Top-Rated AgentsHow This Reshapes the Incentive Structure
Zooming out from the $1,062-per-close math, the program is designed to rewire a handful of industry behaviors at once.
Listing agents get paid to distribute publicly
Before Preview, the pitch to bring a coming-soon listing to a public portal was "exposure." Now it is "exposure plus a revenue share if the tour click converts." That changes the argument a listing agent has with a seller who is leaning toward a private brokerage network, because the agent's incentives are now aligned with public distribution.
Brokerage gatekeeping becomes a recruiting tool
The program is broker-gated, so brokerages that sign on can tell agents "you can only access Preview revenue through us." That is why Samson Properties, Engel & Völkers, SERHANT., and others moved quickly to sign on. It is also a reason independent agents are watching their brokerage's decision carefully.
Compass's private network model is directly targeted
Compass CEO Robert Reffkin has been vocal about the benefits of a private, exclusive listing strategy where listings are marketed to Compass clients first. Zillow Preview is an explicit attempt to make public pre-marketing more attractive than that. Expect continued competitive pressure between these two models through 2026.
Data integrity concerns persist
Inman's April 2026 research found that 51% of agents at Zillow Preview brokerages still believed widespread pre-marketing would undermine market data integrity, compared to 25% at Compass. Days on market, price history, and the accuracy of comparative market analysis all get noisier as more listings sit in a pre-active public window. This is the reason a sizable share of agents at participating brokerages remain skeptical of the program even when their own firm has signed on. For sellers evaluating the tradeoffs before signing with any agent, our list of 15 must-ask questions when choosing a listing agent is a useful place to start.
MLS clear cooperation rules still apply
Zillow Preview listings have to comply with local MLS clear cooperation policies. Some MLS regions permit a coming-soon window of up to 30 days. Others (the Northwest MLS, for example) do not permit coming-soon listings at all. Agents are responsible for confirming their MLS allows the pre-marketing window they are proposing, regardless of what the brokerage has agreed to with Zillow.
What Listing Agents Should Do Right Now
If you are a listing agent, team leader, or broker trying to decide how to respond to Preview, the practical checklist is short.
1. Confirm your brokerage's participation status
Ask your broker whether your firm has signed a Preview agreement with Zillow. If not, ask whether they are evaluating one and on what timeline. If your firm is participating, ask for the current program terms in writing, including how the 10% referral flows through your brokerage split.
2. Verify MLS compliance before you pre-market
Check your local MLS's clear cooperation and coming-soon rules. Confirm how many days a Preview listing can sit in pre-active status before it must be submitted to the MLS, and whether days on market will accrue during the Preview window.
3. Disclose the program to your seller
Sellers should understand that their Preview listing will show two buttons, and that the "Request a Tour" button sends the buyer to a different agent, not to you. Some sellers will view the broader exposure as a win. Others will not. Either way, the conversation belongs upfront, not after the listing is live.
4. Model the upside conservatively
Zillow's 235-million-unique-user audience is real, but most tour requests will not close, and most closings happen on homes other than the one generating the click. Use the calculator above with a conservative tour-to-close rate (1 to 3 percent is a reasonable starting band) before you price the program as incremental revenue in any business plan.
5. Track the legal landscape
The Hagens Berman class action and the CPC report both focus on the Flex/Preferred side of the business. If a court orders material changes to how Zillow discloses or routes referrals, Preview economics could change with them. This is not a reason to avoid the program; it is a reason not to build your annual plan assuming today's fee structure is permanent.

Find a Top Agent NowFrequently Asked Questions
How much does Zillow pay a listing agent on a Preview referral?
Per Errol Samuelson, Zillow's Chief Industry Development Officer, the referral fee equals 10% of the buyer's agent commission when a qualified Preview connection closes through a Zillow Preferred agent. It is paid by Zillow (not by the consumer or the buyer agent) and flows through the listing agent's brokerage. On a $425,000 home with a 2.5% buyer commission, that works out to roughly $1,062 per closed referral.
Can any listing agent participate in Zillow Preview?
No. Access is gated at the brokerage level. An individual agent cannot opt into Preview on their own. Their brokerage has to have a signed partnership agreement with Zillow. The initial launch partners were Keller Williams, RE/MAX, HomeServices of America, Side, and United Real Estate, with additional brokerages added weekly through the spring of 2026.
Does the seller or the buyer pay for this referral fee?
Zillow states the fee is paid by Zillow at no additional cost to consumers or agents. The fee comes out of the revenue Zillow earns from the Preferred buyer agent's success fee at closing, not out of the seller's proceeds or the buyer's closing costs. Commissions between consumers and their agents remain negotiable.
What is the difference between "Contact Agent" and "Request a Tour" on a Zillow listing?
"Contact Agent" routes the buyer directly to the listing agent. Those are free leads for the listing agent during the Preview window. "Request a Tour" (or "Schedule a Tour") routes the buyer to a Zillow Preferred buyer agent, who pays Zillow a success fee at closing. The distinction is the entire basis of a class-action lawsuit filed in September 2025, which argues most consumers do not understand that the two buttons connect them to two different agents.
Does the buyer have to close on the specific Preview listing for the referral to pay out?
No. Based on Zillow's public program description, the referral triggers when a buyer who connected through a Preview listing later closes on any home with the Preferred agent they were matched to. The specific attribution window, exact qualifying conditions, and the full program terms are documented in the brokerage partnership agreement; agents should confirm specifics with their broker.
How is Zillow Preview different from a traditional "coming soon" MLS listing?
A traditional coming-soon MLS status makes the listing visible to other MLS participants and to IDX-feeding portals, subject to clear cooperation rules. A Zillow Preview listing is publicly visible on Zillow and Trulia with the brokerage's branding, elevated placement, and live engagement data (views, saves, tour requests), plus the 10% referral mechanic. Preview listings still need to comply with local MLS coming-soon rules, which vary by region.
Is Zillow Preview the same thing as Zillow Flex?
No, though they interact. Zillow Flex (now branded Zillow Preferred) is the buyer-side program where vetted buyer agents pay Zillow a success fee, typically 15 to 40 percent of their gross commission income, on leads Zillow sends them. Zillow Preview is a seller-side pre-marketing product. The connection: when a Preview listing generates a "Request a Tour" lead, that lead is routed into the Preferred/Flex network, and the success fee Zillow earns on the eventual close is what funds the 10% listing-agent referral.
How does this affect independent agent-matching services that compete with Zillow?
Preview increases the competitive pressure on every lead-generation service that does not have a listing-side revenue story. For consumers, the practical implication is the same as it has been: performance data, not lead-routing fees, is what separates a top-performing agent from an average one. Matching services that rank agents by verified closing performance, like EffectiveAgents, still surface agents who were not necessarily the highest bidder on a zip code or the next name in a Preferred rotation.
