Biggest Gap Ever: Sellers Outnumber Buyers by Half a Million Homes. The raw numbers are staggering. In April 2025, sellers outpaced buyers by 490,041. By July, the gap widened to 518,801—a 36.3% imbalance that Redfin calls the widest on record. For perspective, the last time sellers even slightly outnumbered buyers was over a decade ago, during the tail end of the Great Recession.
