The average per square foot (psf) gap for HDB flats across different floor levels, specifically from level 2 to level 17, in Singapore generally ranges from about 1% to 2% increase in psf per floor as you go higher. In practical terms, for a typical resale HDB flat, this usually translates to an average psf premium of about 5 to 10 dollars per floor, though this amount can vary depending on location, block orientation, views, and market sentiment.
For most transactions in standard blocks, you can expect the aggregate psf difference between level 2 and level 17 to typically range from around 75 to 150 dollars, with the higher-floor units commanding the premium. This means buyers pay more per square foot for units on a higher floor within the same development. The price increment per floor tends to be more significant as you move from lower to mid-levels and may plateau at higher floors, especially if the uppermost levels don’t offer distinctive views.
