From URA’s private residential transactions (caveats lodged), as Flat Prices reads them, Oct 2021 to Oct 2026 (as of 6 Nov 2026). Not every sale has a caveat lodged, and a month’s count fills in over the weeks after it. Bulk sales (several units on one caveat) are listed but left out of the medians.
🏠 Flat Prices
Flat Prices (hdbprices.com) is Liddat’s sister site for Singapore homes. It reads URA’s private residential transactions as they come out, sorts each sale into its project, kind and tenure, and places each project on the map with its nearest MRT station. This page’s sales come from it.
Flat Prices has every HDB resale since 1990 on a map and a page for every block, with rents, the lease left and an estimate of what a flat is worth, and private homes on the same map, so you can set a condo beside the HDB flats around it.
