HDB loan or bank loan

2.6%HDB loan, steady
VariesBank loan, with the market

An HDB loan's rate sits just above the CPF Ordinary Account rate, 2.6% today, and holds steady; a bank's rate moves with the market. Both lend up to 75% of the price. You can move from an HDB loan to a bank later, but not back.

The 30% line

30% of monthly income, the most an HDB instalment can be

An HDB or EC loan's monthly instalment can be at most 30% of gross monthly income (the Mortgage Servicing Ratio). All loans together are capped at 55% (the Total Debt Servicing Ratio).

The downpayment

25% of the price, paid upfront

HDB loan: CPF or cashBank loan: 5% in cash

With an HDB loan the 25% downpayment can come from CPF, cash or both. With a bank loan at least 5% of the price must be cash.

Ordinary Account savings can pay the downpayment and the monthly instalments. What you use, plus the interest it would have earned, goes back to your CPF when you sell.
