What it costs per month of lease
Koon Seng House is freehold, so there is no lease to divide by and no expiry to discount towards. That is the whole of what a buyer is paying the freehold premium for. It runs about a tenth over leasehold on resales in the core central region and in the suburbs, and the city fringe reads the other way. Why that is, and why the national figure is bigger and worse.

Transactions from the Urban Redevelopment Authority, covering Oct 2021 to Oct 2026. URA publishes a rolling five-year window; months before it are held in this site’s own archive. A caveat is lodged after a sale is agreed, so the most recent weeks are always incomplete.
