Compass released data claiming Zillow-listed homes sell at a 2.7 percent discount compared to properties banned from the platform, translating to what the brokerage pegged as a $5,590 average tax per transaction. The math, however, does not hold up under scrutiny.
Compass based its analysis on homes selling at 98.7 percent of asking price on Zillow versus 100 percent for delisted properties. The problem sits in the baseline itself. Asking price is set by the listing agent, not an objective market value. Agents pricing Zillow homes aggressively high to attract traffic would naturally see lower sale-to-list ratios, while agents pricing conservatively would hit or exceed asking price more often.
The brokerage frames the comparison as a Zillow penalty, but the data reveals nothing about actual market performance or buyer behavior. A home could sell for identical prices whether listed on Zillow or not. The gap between asking and sale simply reflects listing strategy, not platform effect.
Zillow delisted over 300,000 inventory listings in 2022 after its iBuying program collapsed, stranding the company with properties it could not offload. Compass used this delisting moment to argue that Zillow's presence depressed home values. The premise skips over the real issue. Properties removed from Zillow faced specific circumstances. Many sat unsold for months. Sellers who relisted elsewhere potentially adjusted prices downward already, explaining any price differential without crediting Zillow's removal.
For sellers, this matters because agent pricing strategy shapes perceived market performance far more than any single platform. Agents who overprice attract traffic but disappoint buyers at showings. Agents who price to market conditions close deals faster and closer to list.
For buyers, the takeaway is simpler. Platform choice among major port
