How HDB sale proceeds are split

  1. Outstanding loan is repaid first, to HDB or your bank.
  2. CPF refund: the CPF principal you used plus accrued interest (2.5% p.a.) goes back to your Ordinary Account.
  3. Fees: agent commission, conveyancing and any resale levy.
  4. The balance is paid to you in cash. If the price does not cover the CPF refund, you may have a “negative sale” for CPF, but you do not need to top up the shortfall in cash.

Frequently asked questions

How much cash will I get from selling my HDB flat?

Take the selling price, subtract the outstanding HDB or bank loan, subtract the CPF you used for the flat plus accrued interest (which goes back to your CPF OA), and subtract agent and legal fees. What remains is your cash proceeds.

Can I use the CPF refunded from my HDB sale for a condo?

Yes. CPF principal and accrued interest refunded to your Ordinary Account can be used for your next property’s down payment (the portion beyond the minimum cash), stamp duty and monthly instalments, subject to CPF rules.

What is CPF accrued interest?

It is the 2.5% p.a. interest you would have earned if the CPF used for your flat had stayed in your OA. It must be refunded, together with the principal, to your CPF account when you sell.
