Yes, you can use your CPF for a progressive payment scheme, except for the booking fee payment. You’ll have to pay 5% of the purchase price in order to get your Option to Purchase (OTP). Keep in mind that this 5% payment has to be made in cash. You can use CPF after the mandatory cash component, which is determined by whether it’s your first or subsequent loan, as well as if you’re taking up to age 65 or beyond.
