Why is bridging different for an HDB flat?
Because of how HDB flats are paid for in the first place. Most flat owners use CPF heavily — for the downpayment and for the monthly instalments — and every dollar of CPF used has to be refunded to the Ordinary Account when the flat is sold, together with the accrued interest it would have earned.
That refund is real money and it is yours, but it lands in CPF rather than in your bank account. On a private sale the split between cash and CPF is often more even. On an HDB sale, CPF frequently takes the larger share.
| Amount | Usable as | |
|---|---|---|
| Sale price | S$600,000 | — |
| Less outstanding loan | − S$220,000 | — |
| Less selling costs (2%) | − S$12,000 | — |
| CPF refunded | S$280,000 | CPF only |
| Cash released | S$88,000 | Cash |
| Total released | S$368,000 | 24% of it spendable |
What is accrued interest and why does it reduce my cash?
When you use CPF to buy a property, CPF treats it as money withdrawn from your retirement savings. On sale you must return not only what you took out but also the interest that money would have earned had it stayed in the Ordinary Account.
The practical effect is that the refund grows every year you hold the flat, and it is deducted from the sale proceeds before you see any cash. A long-held flat can produce a large refund and very little cash even at a healthy sale price.
Check your CPF statement for the exact amount used plus accrued interest before you plan the purchase. It is the single number most likely to surprise you, and it is available to look up rather than estimate.
Why can I be short of cash even with a big refund coming?
Because CPF cannot pay for everything. Under the loan-to-value rules a buyer taking a 75% housing loan has to fund the remaining 25%, and at least 5% of the purchase price must be paid in cash. CPF is not accepted for that slice.
In the example above, S$180,000 is needed before the sale completes and only S$30,000 of usable CPF is on hand, leaving a gap of S$150,000. The sale will cover it comfortably — it just has not happened yet. That timing gap is precisely what the bridging loan is for.
What does an HDB bridging loan cost?
Interest on the bridged amount for the weeks or months until completion. On a S$150,000 bridge at 5% over 6 months that is about S$625 a month and S$3,750 in total.
Terms vary between banks — some charge interest monthly, others roll it up and take it out of the sale proceeds on completion. Ask which applies before you sign, because it changes your monthly cash flow during the overlap.
Does an HDB bridging loan affect my TDSR or MSR?
Not the bridging loan itself, provided it is repaid within six months — MAS excludes such bridging loans from the TDSR rules. That exclusion is what keeps your borrowing capacity intact for the housing loan you are applying for at the same time.
The Mortgage Servicing Ratio still applies to the new HDB flat purchase in the ordinary way: your housing instalment alone cannot exceed 30% of gross monthly income. Bridging does not change that ceiling in either direction.
How do I time an HDB sale and purchase?
HDB resale transactions run to a defined timetable and completion typically falls around eight to twelve weeks after the resale application, which is why the overlap is usually measured in weeks rather than months.
Where possible, line the two completions up closely. Every week of overlap is a week of bridging interest, and the fastest way to reduce the cost of a bridging loan is to need it for less time.
If you are selling a flat and buying private property, remember the ABSD sequence question separately: buying before selling makes the new home a second property, with ABSD attached, reclaimable only through the married-couple remission and only within six months.

Can I get a bridging loan for an HDB flat?
Yes. MAS Notice 633 governs bridging loans to individuals and explicitly covers bridging loans used for the purchase of an HDB flat. The lender is a bank — HDB itself does not offer bridging.
Does HDB provide bridging loans?
No. Bridging is a bank product. HDB provides the concessionary housing loan for the purchase itself, but the short-term facility that covers the gap between selling and buying comes from a bank.
Why is my cash from an HDB sale so much lower than the sale price?
Because the outstanding loan is repaid first, selling costs come off, and the CPF you used — plus accrued interest — is refunded to your Ordinary Account rather than paid to you. On a long-held flat that refund can be the largest single deduction.
What is accrued interest on CPF used for a flat?
The interest your CPF savings would have earned had you not withdrawn them for the property. It is added to the amount you must refund on sale, so the refund grows the longer you hold the flat.
Can I use my CPF refund for the cash portion of my next home?
No. At least 5% of the purchase price must be paid in cash under the loan-to-value rules, and CPF is not accepted for that portion. This is the most common reason an HDB seller with a healthy sale still needs bridging.
Does a bridging loan count towards MSR on an HDB purchase?
The bridging loan is excluded from TDSR where it is repaid within six months. The Mortgage Servicing Ratio still applies to the new flat's housing instalment in the normal way — capped at 30% of gross monthly income.
How long is an HDB bridging loan needed for?
Usually weeks rather than the full six months, since HDB resale completion typically falls around eight to twelve weeks after the resale application. The shorter the overlap you can arrange, the less the bridging costs.
What if my flat does not sell?
The bridging loan still has to be repaid and the source you were counting on has not materialised. Lenders want a firm sale in place before advancing bridging for exactly this reason. Raise the scenario with your lender before you commit to the purchase.
