What happens when you join every private transaction, every HDB resale, census income, Master Plan zoning and the development pipeline into one spatial database — and just look. Every chart below is computed live from official records; 2,657 of 2,980 condos sit in residential zones, and the rest of the structure is exactly as interesting.
Each dot is one planning area. Household income and HDB resale PSF rise together — affluent estates lift both. The interesting dots are the outliers: high-income areas where HDB is still cheap (usually older flats with decaying leases), and modest-income areas where HDB commands a premium (usually young, central estates).
For every condo we compute its PSF against the median HDB resale PSF in the same planning area. Most of Singapore's condos cost 50–250% more per square foot than the public housing next door. The long right tail is the Core Central Region — D9, D10 and the Marina fringe, where the premium runs past 400%.
Bukit Timah leads the island at roughly $22.5K a month — more than triple the bottom of the table. The spread is the real stratification of Singapore, and it shows up everywhere downstream: in HDB prices, in condo premiums, in which districts absorb new launches fastest.
Districts with a tall bar have a lot of new private housing on the way relative to what already stands — historically a buyer's-market signal, since incoming supply competes with resale stock. D1 tops the chart on the back of large integrated launches in the CBD.
A higher PSF usually means a higher premium over local HDB — but not always. A $2,000-PSF condo in Bedok, where HDB is cheap, can carry a fatter premium than a $3,000-PSF condo in Tiong Bahru, where HDB is expensive. The premium measures what you pay for the private label in that specific neighborhood.
The classic trade-off, visible in raw data: cheaper heartland stock rents harder per dollar of purchase price, while prime CCR property earns its keep through capital appreciation, not rent. If you're buying for cash flow, the top-left of this chart is your hunting ground.
