Zillow Preview listings are now visible on Realtor.com. Realtor.com’s own Preview listings are now visible on Zillow, too. Both changes went live today, September 17, 2026.
Before this, seeing a pre-market home early depended on which site or agent network a buyer used. Now the same pre-MLS inventory shows up on both platforms, labeled and searchable, with no special login or brokerage relationship needed.
Here’s what buyers can do with a Preview listing on either site, and what the rollout means for the sellers and agents marketing homes before they reach the MLS.
How Preview Listings Work for Buyers
A buyer doesn’t need a login or a relationship with a specific brokerage to see Preview listings on Zillow or Realtor.com. The listings are labeled as Preview and get bumped up in search results and email alerts on both sites.
Once a buyer finds one, they can:
- Save it to get updates as more details get added
- Contact the listing agent with questions
- Book a tour ahead of the home’s official showing date
- Connect with a buyer’s agent and get pre-approved before the home goes live
More than 400 brokerage partners are enrolled in Zillow Preview already, including:
- Keller Williams
- RE/MAX
- HomeServices of America
- Berkshire Hathaway HomeServices (BHHS)
- United Real Estate
- Engel & Völkers
- Side
Listing creation keeps growing as more brokerages sign on. And earlier this week, Zillow announced that Preview listings will also be available on RealScout starting later this year.
A Harris Poll survey commissioned by Zillow found that 88% of Americans would be at least somewhat interested in viewing pre-listed homes online if they were buying.
Zillow’s chief product officer, Christopher Roberts, framed the rollout as a break from how some competitors handle early access.
“Today we set a new standard for pre-market transparency on Zillow and Realtor.com. While others in this industry are moving in the other direction and restricting early listings to private networks, we’re proving that broad, public visibility is better for sellers, better for buyers and better for agents.”
What the Rollout Means for Sellers and Agents
Zillow and Realtor.com together reach three-quarters of major portal visitors, according to Comscore data cited in the announcement. This combined reach gives sellers a bigger audience during the window before a home hits the MLS.
In their first 14 days on market, Preview listings outperformed comparable listings on:
- Views (up 18%)
- Shares (up 9%)
- Saves (up 7%)
Buyer activity during the Preview window, like saved searches and tour requests, gives sellers and their agents a read on pricing before the home officially lists.
A separate stat from the announcement found that 85% of soon-to-be sellers said they’d be more likely to hire an agent who could market their home to the widest online audience before listing.
All of this comes at no added cost to sellers or agents working through an enrolled brokerage. Agents who participate get:
- Elevated placement in search results and saved-home alerts during the Preview period
- Free connections when a buyer contacts the listing agent through either platform
- A share of the revenue when a qualified Preview connection closes through a qualified partner agent, paid out through the brokerage, with commissions still open to negotiation
Anna Marie Castiglioni, who leads Realtor.com Next, explained why the two companies combined their Preview programs instead of running them apart.
“Bringing Preview Listings to both platforms means every buyer, on either site, gets access to the same homes at the same time, and every seller gets the benefit of that broad reach.”
Where the Preview Rollout Goes From Here
This launch follows a collaboration between Zillow and Realtor.com that the two companies first announced in May 2026.
Brokerage enrollment has already passed 400 partners, and both companies say the number keeps climbing as more brokerages sign on.
For agents, the thing to watch is how many more brokerages join.
With 400 partners and growing, if pre-market marketing isn’t already a standard step in how your sellers’ listings get introduced, it probably should be.
