Background

Singapore's property market is shaped by cooling measures introduced since 2009, including Additional Buyer's Stamp Duty, loan-to-value limits and debt servicing ratios. These rules are adjusted when the market runs hot, so the numbers you see today may differ from what friends paid a few years ago.

Beyond the price, buyers should budget for legal fees, valuation, home insurance, renovation and furnishing. Running the figures in advance helps you decide how much cash to hold back and whether a smaller loan or longer tenure makes more sense.
