Stale Listings
Buildings whose listings have sat unsold for the longest. Long days-on-market without a price reduction = priced too high vs market interest. RealData stamps each listing's first appearance, so we can show this signal hipflat doesn't expose.
Days-on-Market data accumulates from each weekly Tier B re-scrape. The longer this site runs, the sharper the signal.
No stale buildings yet — DOM data is still accumulating. Check back next week.
