Many consumers think Zillow is the MLS. It’s not — not even close.
The MLS (Multiple Listing Service) is a cooperative database run by REALTOR® associations like HAR, where every listing is:
Verified by licensed member agents
Updated in real time
Monitored for accuracy and compliance
Subject to fines if information is not current
If a property has closed, gone pending, or been withdrawn, agents are required to update the status promptly — or face fines.
Zillow, on the other hand, is a marketing portal. It scrapes or receives one-time data feeds from MLSs or brokers. After that initial pull, it’s no longer synchronized unless a brokerage pays for a direct feed. So outdated listings remain visible, misleading buyers, sellers, and even appraisers.
In short: the MLS is truth; Zillow is advertising.
Here’s what most consumers — and even some agents — don’t realize.
Every person conducting real estate activity in Texas must hold a TREC license.
But not all licensees are REALTORS®.
To be a REALTOR®, you must:
Be a dues-paying member of the National Association of REALTORS® (NAR)
Join your state association (Texas REALTORS®)
Join your local board (like HAR)
Abide by a strict Code of Ethics
Operate within a governed MLS system
Non-REALTOR® licensees hold the same state license, but they are not bound by any ethical standards beyond TREC’s legal minimums — and they have no MLS access or enforcement oversight.
Many of these agents list properties only on third-party sites like Zillow, because they can’t use the MLS. There are no data checks, no accuracy fines, and no peer accountability.
This creates a two-tier system:
REALTORS® are held to professional and ethical standards.
Non-members operate freely in the unregulated space of online portals.
The consumer can’t tell the difference — but the impact on our profession is enormous.
Buyers chase “active” listings that actually sold weeks ago.
Sellers are frustrated that their homes show up incorrectly online.
REALTORS® are blamed for data they didn’t control.
Zillow’s disclaimer (“Information deemed reliable but not guaranteed”) doesn’t fix the fact that consumers believe what they see.
And when they see inaccuracies, it reflects on us — not the platform.
That’s the gray zone.
TREC regulates licensees, not technology companies.
Zillow and other portals aren’t brokerages in Texas (even if they are elsewhere), so TREC can’t enforce accuracy or ethical obligations.
But consumer protection is a core part of TREC’s mission — and many of us believe it’s time for state-level collaboration with NAR, Texas REALTORS®, and local MLSs to establish baseline data-integrity standards for public listing sites.
Until that happens, misinformation will continue to erode consumer trust — and REALTORS® will continue cleaning up the mess.
Let’s be honest.
When REALTORS® pay Zillow for leads, we’re buying back our own listings.
We created the data — every photo, description, and update — and now we’re paying a marketing company to sell those leads back to us.
It’s like growing your own coffee beans and then buying them from a scalper outside your shop.
Or worse — like going to a drug dealer and buying a hit of your own product.
It’s self-defeating.
We’ve built the very system that profits from our work and conditions consumers to believe Zillow is the authority, not us.
Zillow didn’t steal our business.
We handed it over.
Every time we pay for a “Premier Agent” badge or boost an ad, we reinforce a model that thrives on selling our own customers back to us.
The fix isn’t to ban Zillow — it’s to reclaim power.
That starts by:
Directing clients to MLS-verified sources like HAR.com.
Emphasizing that REALTORS® are accountable to ethics and truth, not clicks.
Educating consumers that Zillow is a marketing site, not an official data source.
Refusing to fund systems that commoditize our credibility.
Because the more we depend on Zillow, the more we erode the value of our own MLS and professional standards.
The REALTOR® “R” stands for something: Respect, Responsibility, and Real Relationships.
Zillow builds algorithms. REALTORS® build trust.
One serves advertisers; the other serves people.
If we want to preserve the integrity of our profession, we must stop buying back what we already own — and start investing again in truth, transparency, and the MLS that built us.
