Background

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.

CPF Ordinary Account savings can pay for the downpayment, stamp duties and monthly instalments, but using CPF reduces the money compounding for retirement, and the amount withdrawn plus accrued interest must be refunded to your CPF account when you sell.
