Buyer financing is already restricted

Your block has 57 years of lease left. Buyers already face CPF usage limits and lower loan quantum when purchasing. This means fewer buyers qualify, and those who do will negotiate harder. Selling sooner gives you a larger buyer pool and a stronger sale price.

A specialist agent can target the right buyers and negotiate the best possible outcome for you.

How much cash will I actually receive when I sell my flat at Block 237?

Your gross sale proceeds are what the buyer pays. From that, three things are deducted: your outstanding loan, your CPF principal (all CPF savings used for the flat, returned to your CPF OA), and CPF accrued interest (the interest CPF calculates on those savings at 2.5% p.a., compounded annually). What remains after these deductions is your cash in hand. Use the What's Your Flat Worth? calculator above to estimate your actual cash take-home based on Block 237 prices.

What is CPF accrued interest and why does it reduce my sale proceeds?

When you buy a flat using CPF, those funds are considered a loan from your CPF OA to yourself. When you sell, CPF Board requires you to return the principal plus the interest those funds would have earned had they stayed in your OA — currently 2.5% per annum, compounded. This is not a penalty or a fee paid to anyone; the money goes back into your CPF OA. However, it does reduce your cash proceeds — and the longer you have owned the flat, the larger the accrued amount. Use the CPF Accrued Interest Calculator above to estimate your deduction before you decide to sell.

Selling to upgrade means planning both timelines and funds. Your proceeds split into cash in hand (for your next downpayment and transition costs) and CPF refund (returned to CPF OA). Use the What's Your Flat Worth? calculator above to estimate the equity you can deploy for your next home.

What is the remaining lease for Block 237?

Does Block 237's remaining lease affect its resale value?

Can I sell my HDB flat without an agent?

Yes — HDB's resale portal allows you to handle the transaction yourself.

The typical 1–2% commission is often recovered through a stronger sale outcome.
