Property portals start a listing's clock again every time it's relisted, so a home "added three weeks ago" may have been for sale since spring. Stale Bricks keeps every asking price from the first advert and scores live UK listings 0–100 on their price reductions, time for sale, signs of the seller's situation (probate, a sale that fell through, no onward chain) and the local market. Search is free, and a free account shows the top two homes for any search.
