Before you look at any new home, look at what your current flat actually frees up. A simple way to estimate your HDB sale proceeds:
Selling price − outstanding housing loan − (CPF used + CPF accrued interest) − selling costs = estimated cash proceeds
Here’s the part many people miss.
The CPF refund when selling your HDB goes back into your CPF Ordinary Account, not your bank account. The principal you originally used, plus CPF accrued interest at 2.5% per year, must be returned to your OA.
That refunded CPF isn’t gone — it can generally be reused for your next home, subject to CPF rules. But it changes one thing that matters a lot: how much cash you walk away with versus how much sits inside CPF.
Simplified example (illustration only). Sell at $750,000. Outstanding loan $180,000. CPF used plus accrued interest $250,000. Selling costs roughly $15,000.
Estimated cash proceeds ≈ $305,000 — while $250,000 returns to your CPF OA. Two very different numbers, and you need both before deciding.
