A household can have enough wealth to pay for a new HDB flat and still be unable to make the payment on key-collection day.
The reason is timing.
Much of the household’s money may still be locked inside the HDB flat it is selling.
HDB’s Temporary Loan Scheme, or TLS, is designed for a specific version of this problem.
It helps eligible buyers who intend to pay for a flat bought from HDB using the net proceeds from the sale of their existing flat, without taking a long-term housing loan for the new purchase.
Official HDB guidance: Temporary Loan Scheme.

This article reflects HDB guidance available on 4 September 2026.
Quick Answer
The Temporary Loan Scheme gives an eligible buyer a short-term loan secured by the new HDB flat so the purchase can complete before the sale proceeds from the existing flat have fully arrived.
The loan is then redeemed using the net proceeds from the sale of the existing flat.
BUY NEW FLAT FROM HDB → SALE OF OLD FLAT STILL IN PROGRESS → TEMPORARY LOAN FILLS THE TIMING GAP → COLLECT KEYS → OLD FLAT SALE COMPLETES → CPF REFUND + CASH PROCEEDS REDEEM TEMPORARY LOAN
HDB states that the TLS does not cover the downpayment and carries the prevailing non-concessionary interest rate.
Wait, What? TLS Is for a Buyer Who Does Not Want a Long-Term Housing Loan
This is the central distinction.
The household plans to pay for the new flat using:
- available CPF OA savings;
- CPF refunded from the old flat;
- cash proceeds from the old flat;
- and any required cash top-up.
In the final state, the household does not need the temporary loan to remain.
The TLS exists only because the old sale has not finished releasing those funds yet.
The New Flat Becomes the Temporary Mortgage
HDB states that the temporary loan is secured as a mortgage over the new flat.
This matters because TLS is not an unsecured cash advance.
The new home is the security while the old-home proceeds are still travelling through the system.
The Old Flat Sale Must Already Be Real
To qualify, HDB currently requires the household to have booked the new flat, received the invitation to collect keys, and applied to sell the existing flat.
If the old flat has a housing loan from a financial institution, that loan must be fully redeemed under the applicable TLS conditions.
This prevents the scheme from being used while the old-housing debt structure is still unresolved.
The Full Purchase Price Still Has to Be Covered Eventually
HDB states that the household must be able to pay the full purchase price using the relevant combination of OA savings, CPF refund and cash proceeds from the old flat.
If those funds are insufficient, the household must be able to top up the shortfall by the date HDB specifies before the TLS request can be considered.
Again:
TLS FIXES TIMING. IT DOES NOT FIX AN UNDERFUNDED PURCHASE.
The Downpayment Is Outside the TLS
HDB explicitly states that the TLS does not cover the downpayment.
The household must therefore arrive at key-collection stage having already satisfied the earlier payment obligations under the purchase route.
The temporary loan bridges the remaining purchase amount that is waiting for old-flat proceeds.
The Interest Rate Is Non-Concessionary
HDB states that the temporary loan carries the prevailing non-concessionary interest rate.
That creates an incentive for the loan to remain temporary.
The household should not treat TLS as a cheap long-term substitute for an ordinary housing loan.
Why the Scheme Can Be Valuable
Without TLS, a household might have to choose among awkward alternatives:
- sell the old flat much earlier;
- find temporary accommodation;
- delay key collection where that is not viable;
- take a longer-term loan it never really intended to keep;
- raise temporary cash elsewhere.
TLS keeps the financing aligned with the household’s real long-term plan: pay for the new flat from accumulated housing wealth, but bridge the short release delay.
Why Key Collection Comes After Approval
HDB currently states that the household will be invited to collect the keys after the resale application and temporary-loan application have been approved.
This synchronises the three essential states:
- old flat is genuinely being sold;
- temporary finance is approved;
- new flat is ready for possession.
TLS Is Different From Contra Payment Facility
HDB’s key-collection guidance places the two mechanisms beside each other because both solve old-home-to-new-home cash-flow problems.
But they serve different financing states.
Contra Payment Facility
For eligible buyers using an HDB housing loan to buy the new flat from HDB while selling the existing flat.
Temporary Loan Scheme
For eligible buyers who do not intend to take a long-term housing loan for the new flat and instead plan to pay using the old-flat sale proceeds.
Same timing problem.
Different long-term debt plan.
TLS Is Also Different From Enhanced Contra Facility
Enhanced Contra Facility is primarily a resale-to-resale mechanism.
TLS belongs to the key-collection path for a flat bought from HDB.
These distinctions matter because the user should not search for one generic “HDB bridging loan” and assume every transition route behaves the same way.
Failure Mode: Treating TLS as Proof You Can Delay Selling Indefinitely
The temporary loan has to be redeemed from the old-flat sale proceeds.
If the sale is delayed, the household remains exposed to temporary-loan interest and the wider disposal deadline.
Temporary finance works best when the old sale is already genuinely progressing.
Failure Mode: Assuming the Old Flat Will Sell at the Asking Price
The TLS funding plan depends on net sale proceeds.
If the old flat sells for less than expected, the household may need more cash to close the difference.
Use conservative proceeds, not aspirational listing value.
Failure Mode: Forgetting the Six-Month Disposal Clock
Existing HDB flat owners who collect keys to another HDB flat are generally required to dispose of the old flat within six months under the prevailing route conditions.
TLS does not cancel that obligation.
The final article in this batch owns the disposal timeline directly.
Forward Play: Follow the Temporary Loan
The new flat is ready.
The old flat is under sale.
TLS fills the temporary purchase gap.
The household collects keys.
The old sale completes.
CPF and cash proceeds arrive.
The temporary mortgage is redeemed.
The household reaches its intended final state: new HDB home, no long-term housing loan.
Reverse Play: Start From the Debt-Free New Home
How did the household collect keys before the old sale finished?
A temporary mortgage carried the timing gap.
How did that mortgage disappear?
The old home released the capital that was always meant to pay for the new one.
TLS is best understood from the final state backwards.
The Deepest Answer
The Temporary Loan Scheme exists because housing wealth moves slowly even when the household decision is already complete.
The old flat may contain enough value to buy the next flat outright.
But title transfer, CPF refund and sale completion take time.
TLS inserts a temporary mortgage into that interval.
It is not long-term borrowing disguised as convenience.
It is a bridge that disappears when the old housing capital finally arrives.
