What’s Going On With Zillow? A Breakdown of the Lawsuits, Controversies, and What It Means for Washington Buyers and Agents

Zillow has dominated the online real estate landscape for more than a decade — but over the past year, the company has faced mounting legal pressure, federal scrutiny, and industry backlash. If you are a Washington homebuyer, seller, or agent, these developments matter. They could reshape how referrals work, how mortgages are recommended, and how listing data is displayed across the country.

Here is a clear, comprehensive breakdown of what is happening, why it matters, and how it could affect your next home decision.

1. The Lawsuits Around Zillow’s Flex Program and Alleged “Steering”

The Class-Action Lawsuit (September 2025)

In September 2025, a class-action lawsuit — Taylor v. Zillow, Inc. — was filed in the U.S. District Court for the Western District of Washington. The lawsuit alleges that Zillow’s “Flex” partner-agent program misled consumers by routing them to Zillow-affiliated buyer agents without disclosing that those agents were paying Zillow up to 40 percent of their commission for the lead.

This is significant because many consumers who clicked “Contact Agent” believed they were contacting the listing agent — not a Zillow-selected buyer’s agent paying referral fees behind the scenes.

The complaint argues that this violates:
• RESPA (Real Estate Settlement Procedures Act)
• Washington state consumer-protection laws
• Basic disclosure and transparency standards

If proven, it could signal major changes in how online referral programs are allowed to function.

2. Expanded Claims: Mortgage Steering and Internal Pressure (November 2025)

On November 19, 2025, the lawsuit expanded with new allegations involving Zillow Home Loans.

According to the amended complaint, Zillow allegedly:
• Used internal quotas to pressure partner agents to refer borrowers to Zillow Home Loans
• Penalized agents who recommended outside lenders
• Monitored agent–client conversations through internal communication tools
• Prevented agents from discussing alternative loan options

These accusations could amount to a brokerage-lending conspiracy, violating fiduciary duties and mortgage-disclosure laws.

For buyers, this raises a critical question:
Were some borrowers steered into mortgage products that weren’t in their best interest?

3. Federal Trade Commission (FTC) Lawsuit: Rental Advertising Antitrust Case

Separate from the class-action case, the FTC has filed a major antitrust lawsuit alleging Zillow and Redfin reached an agreement in the rental-advertising market.

The FTC claims Zillow paid Redfin $100 million not to compete in multifamily rental advertising for up to nine years.

The FTC argues this:
• Reduces competition
• Limits choices for property managers and renters
• Centralizes power under Zillow
• Potentially raises advertising costs

This case could reshape how rental listings appear online and whether new competitors emerge.

4. Climate-Risk Scores Quietly Removed From Zillow Listings

In 2024, Zillow began showing flood, fire, and climate-risk scores based on First Street Foundation data. But in December 2025, those scores disappeared from over a million listings.

Zillow now links out to First Street, rather than embedding the scores directly.

The shift followed:
• MLS complaints — especially from CRMLS
• Agent concerns that inaccurate risk scores were hurting property values
• Homeowner frustration that buyers were being scared off by “algorithmic” risk models

For Washington buyers, especially in areas with wildfire or flood considerations, this means less upfront transparency.

As an agent, being proactive about climate disclosure can now be a point of differentiation. I regularly direct clients to tools such as flood maps, wildfire projections, and local hazard assessments.

5. Why This Matters for Homebuyers and Sellers in Washington

The combined legal and regulatory pressure raises important implications:

For Buyers

You may have previously been directed to partner agents or mortgage providers without full transparency. If the class is certified, buyers could see refunds, credits, or new disclosure protections.

For Sellers

These cases could impact the platforms that showcase your home. More regulation may mean more clarity — but also potentially less power concentrated in one portal.

For Agents (especially those prioritizing transparency)

Independent agents who offer:
• full fee disclosure
• unbiased mortgage guidance
• transparent buyer-agency relationships

…may gain a competitive advantage as consumers become more aware of referral-fee structures.

If new rules restrict Zillow’s ability to steer leads, more buyers may look for local agents they trust, not platform-generated referrals.

6. What Happens Next?

These cases could expand further and may take several years to resolve. But regardless of the outcomes, one trend is clear:

Transparency is becoming a currency in real estate.

Consumers want to know:
• Who is getting paid
• How referrals work
• Whether mortgage recommendations are unbiased
• Whether listing data is complete, accurate, and unaffiliated

The current moment offers an opportunity for more open, client-focused real estate practices.

Final Thoughts

Zillow’s legal challenges reflect a broader shift in the real estate industry toward higher accountability. For Washington residents, the biggest takeaway is this: The market is changing, and informed decision-making matters more than ever.
