The Progressive Payment Scheme is the quiet superpower of buying a new launch as an HDB upgrader. Instead of paying for your condo all at once, you pay in stages tied to construction — a small amount now, the rest drawn down over the years it takes to build. For someone juggling an HDB sale, that staggered schedule can be the difference between a comfortable upgrade and a cash crunch.
But it only works in your favour if you understand the schedule and plan around it. Let me break down each stage, map it to the building timeline, and show you where a bridging loan does — and doesn’t — belong.
See your net sale proceeds and cash position so you can match them to the progressive draws.
How progressive payment works
When you buy a unit that’s still under construction (a “BUC” property), you pay according to the Progressive Payment Scheme (PPS). Each payment is triggered by a construction milestone. Critically, your bank loan also disburses progressively — so in the early years you’re only paying interest on the small amount drawn so far, not the full loan. That’s what keeps early cash flow gentle.
The stage-by-stage schedule
Here’s the standard PPS breakdown for a private new launch. Percentages are of the purchase price:
| Stage / milestone | Payment | Running total |
|---|---|---|
| Booking fee (Option to Purchase) | 5% | 5% |
| Signing S&P / within ~8 weeks | 15% | 20% |
| Completion of foundation | 10% | 30% |
| Completion of reinforced concrete framework | 10% | 40% |
| Completion of brick walls | 5% | 45% |
| Completion of roofing / ceiling | 5% | 50% |
| Completion of door/window frames, wiring, plastering | 5% | 55% |
| Completion of car parks, roads, drains | 5% | 60% |
| Temporary Occupation Permit (TOP) — move-in | 25% | 85% |
| Certificate of Statutory Completion (CSC) | 15% | 100% |
The first 20% is your downpayment (the 5% booking must be cash; the 15% can be cash/CPF). From the foundation stage onward, your bank loan kicks in and covers the progressive draws, so you’re servicing an increasing mortgage as construction advances — but only on the portion disbursed.
Why this suits upgraders
Map the schedule against your HDB sale and the advantage becomes obvious:
- Small upfront outlay. You only need the 20% downpayment (and stamp duties) to secure the unit — far less cash than a resale’s full payment.
- The big draws come later. By the time foundation and structural stages trigger larger disbursements, your HDB sale has likely completed, putting proceeds and refunded CPF in your hands.
- You avoid interim housing. You keep living in your HDB (or move once) while the condo is built, then move straight in at TOP — no rental gap.
A worked cash-flow picture
Take a $1.5M new launch, buying before selling the HDB, then selling during construction:
- Now (booking + S&P): Pay 20% downpayment = $300,000 (5% cash + 15% cash/CPF), plus BSD (~$44,600). This is your real upfront hurdle.
- Year 1–2 (foundation, structure): Loan disburses for these draws; you service a growing mortgage on the drawn portion. Your HDB sale completes here, freeing proceeds and CPF.
- TOP (~year 3–4): The 25% draw lands; you move in. Your full mortgage is now largely in force.
- CSC (~year 4–5): Final 15% drawn; loan fully disbursed.
The key planning point: ensure your HDB sale completes before the heavier mid-construction draws, so the proceeds and refunded CPF are available when the mortgage ramps up.
When you still need a bridging loan
The PPS reduces — but doesn’t always eliminate — the need for bridging finance. You may still need a bridging loan if:
- You buy before selling and the early draws (or ABSD float) fall due before your HDB proceeds arrive.
- Your HDB sale completes later than expected, leaving a gap before the proceeds reach you.
A bridging loan (typically up to 6 months) advances your expected sale proceeds to cover that gap, repaid once the sale completes. Remember it counts toward your TDSR while outstanding. The interplay of timing, bridging, and completion dates is covered in Simultaneous Sale and Purchase.
Don’t forget the cash floor and ABSD
Two reminders the staged schedule can obscure:
- The 5% booking fee must be cash — CPF can’t cover it. On a $1.5M unit, that’s $75,000 ready on day one.
- If you buy before selling, you still pay 20% ABSD upfront (refundable in 6 months) regardless of the progressive schedule — see ABSD for HDB Sellers.
The bottom line
The Progressive Payment Scheme lets you secure a new launch with just a 20% downpayment, then pay the rest in construction-linked stages while your loan disburses progressively — keeping early cash flow light. For upgraders, the schedule aligns beautifully with selling an HDB: light upfront, heavier draws later once your proceeds are in hand. Plan your sale to complete before the mid-construction draws, keep the 5% cash and any ABSD float ready, and use a bridging loan only to smooth genuine timing gaps.
Net cash from your HDB sale, ABSD exposure, and the condo budget you can actually afford — worked out in about 2 minutes.
