How the ranking works
Each ZIP code with enough recent sales gets a competition score from 0 to 100 based on four measures: the share of homes sold above their original list price, the average sale-to-list ratio, months of supply and median days on market. Scores compare every U.S. ZIP code against the others and update monthly from Redfin data. Methodology
