A briefing for MLS CEOs
MLS CEOs face growing pressure to interpret delayed listings through the lens of compliance risk, consumer transparency, and platform integrity. The public sees every delay as a potential rule violation. Zillow’s enforcement amplifies that pressure by threatening bans that remove listings from one of the largest consumer portals for the life of the listing.
Inside Compass and Howard Hanna, the reality is more nuanced. The largest share of delayed listings in both companies is tied to structured seller service programs that require preparation time and managerial review. If these brokerages do not operate in your market, you may be unaware of their long standing seller offerings.
Understanding these programs matters. It helps MLSs distinguish between legitimate consumer-driven timing and improper withholding.
Research from BrightMLS done this year shows what Compass and Howard Hanna have known for a decade: home buyers prefer move-in ready homes. These properties sell faster and for higher prices.
How Compass Concierge affects timing
Compass Concierge funds presale improvements that elevate the value and presentation of a home. Sellers repay the cost at closing. The program requires scheduling contractors, completing work, and producing professional photography. Listings stay offline until the home is ready.
Compass managers document the delay, align it with the seller’s goals, and approve the launch timeline. This is a structured consumer service that results in cleaner, higher-quality listings entering the MLS.
WAV Group authored a playbook on how other brokers can elevate their seller programs to match those from Compass using off the shelf technology solutions and listing presentations.

How Howard Hanna’s Buy Before You Sell program shapes timing
Howard Hanna advances equity to allow sellers to purchase their next home before listing their current one. This eliminates contingencies and supports a smoother transition.
That transition dictates when the listing becomes market ready. Sellers may need time to vacate, complete repairs, or prepare the home for photography and showings. Hanna managers oversee each step and confirm that timing aligns with the seller’s plan.
These delays are operational, not strategic withholding.
What the data shows about Zillow’s enforcement
Mike DelPrete’s research highlights where the pressure is concentrated specifically to Compass and Howard Hanna. Link to research.
Zillow has banned only 48 listings nationwide as of November 14 according to DelPrete. About 90 percent are Compass listings. The remaining 10 percent are Howard Hanna listings. DelPrete claims that no other brokerage has faced bans. Read WAV Group’s coverage on the story of Zillow becoming a rule maker here.
Zillow has issued 1,202 violation notices to 24 brokerages. Compass agents received 1,137 of them, which equals 95 percent. Hanna accounts for nearly all of the remainder.
Enforcement has been most intense in the mid-Atlantic, with early expansion into Texas and Florida.
Industry perception is far from reality. In DelPrete’s survey of 870 respondents, 80 percent believed the ban count exceeded 50. Nearly half guessed more than 1,000. The real number is 48.
This data illustrates two points relevant to MLS CEOs:
- Enforcement is narrow and concentrated
- Compass and Howard Hanna are absorbing the majority of scrutiny because their programs generate the most structured delays
Understanding this context helps MLSs separate systemic issues from targeted enforcement.

Why this matters to MLS operations and governance
MLSs often receive complaints about delayed listings or assumptions that a brokerage is “hiding” inventory. When those concerns involve large firms, pressure rises quickly.
Reviewing the Compass and Hanna models shows that many delays are:
- Tied to seller-requested improvements
- Dictated by transitional logistics
- Documented and approved by management
- Positioned to result in a stronger listing once it reaches the MLS
This distinction is critical for compliance teams, data integrity strategies, and communication with brokers. The goal is for consistent contribution, but timing should not be mistaken for intent.
MLSs that understand the operational reasons behind these delays are better positioned to make informed decisions, respond to complaints accurately, and maintain trust across stakeholders.
A brief note on policy discussions ahead
The Clear Cooperation Policy is expected to face a repeal motion at the REALTORS® Legislative Meetings (NAR mid-year) in Washington D.C. If your MLS has a position on CCP or concerns about how delayed listings should be governed going forward, participation at NAR mid-year is essential.
