HDB valuation guide

How to compare HDB resale PSF across estates

Resale price per square foot (PSF) makes different flat sizes easier to compare, but it is not a standalone valuation. The most useful comparison keeps estate, flat type, transaction period and remaining lease in view.

Short answer: compare the latest local PSF with a sufficiently large recent sample, then use the five-year trend and lease-adjusted benchmark to test whether the current level looks unusually high or low.

What HDB resale PSF means

Resale PSF is the transacted resale price divided by the flat’s floor area. PropertySignals groups valid transaction records by estate and flat type, calculates comparable PSF observations, and reports the median or range when coverage is sufficient.

Four checks before comparing PSF

Check	Why it matters
Same flat type	A 4-room benchmark should not be used as a direct substitute for a 2-room or 5-room benchmark.
Recent period	Older transactions may describe a different rate environment and market cycle.
Sample size	A small number of transactions can make a median unstable or unrepresentative.
Remaining lease	Two flats with the same PSF may have materially different tenure and financing context.

How to use the PropertySignals chart

Start with the selected estate’s current median PSF.
Review the five-year growth series and compare it with nearby or national context.
Check the transaction count and displayed data period.
Use the fair-PSF signal only when the page says the high-tenure benchmark has enough coverage.

Important: PSF is a comparison signal, not a promise of future appreciation. It does not replace a unit-level valuation, viewing, legal review or financing assessment.
