Your flat is approaching a key resale threshold

Your block has 66 years of lease left. Today, buyers can still get full CPF and bank loans — no restrictions. But once the lease drops below 65 years, buyers who purchase now will struggle to resell after their MOP. The closer you get, the smaller your buyer pool becomes.

How much cash will I actually receive when I sell my flat at Block 423?

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 423 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.
