Progressive Payment Diary 2026: How a First-Time Buyer Funded a $1.65M New Launch Over 3 Years

Expert takeaway: On a $1,650,000 new launch, first-time buyer Boon Kiat needed $464,600 across the first two stages, but only $82,500 of that had to be cash. The rest of the money arrived on the developer's construction timeline, and understanding that rhythm is what separates a comfortable purchase from a stressful one.

Why the progressive payment scheme decides your cash flow, not just your price

When Boon Kiat, a 33-year-old engineer buying his first home, put down his booking cheque on a $1.65M two-bedroom-plus-study unit in a city-fringe new launch, he assumed the hard part was choosing the unit. It was not. The real work was mapping when each dollar of cash, CPF and bank loan would leave his account over the next three years. This is the progressive payment scheme in action, and it is the default structure for almost every new launch condo purchase in Singapore.

When you buy a Building Under Construction unit from a licensed developer, you do not pay the full price upfront. URA and the Ministry of National Development govern uncompleted private residential sales under the Housing Developers Rules, and payments are staggered across defined construction milestones certified by the project architect. Money only changes hands as the building physically rises, from foundation to walls to roof and finally the keys.

For context on the market Boon Kiat was buying into: URA's Q2 2026 data showed private home prices rose just 0.5% quarter-on-quarter, the slowest pace in seven quarters. Financing was the friendliest it had been in years, with 3-month compounded SORA at 1.19% and fixed home loan packages starting from 1.40% in September 2026. That backdrop shaped every decision below.

Stage one and two: the $464,600 that lands before construction even starts

The front-loaded part of the scheme is where first-time buyers get caught out. The first two payments arrive within roughly eight weeks of each other, long before the crane appears on site.

At the Option to Purchase, Boon Kiat paid the 5% booking fee, which must be cash. On $1,650,000 that was $82,500. Roughly eight weeks later, on exercising the Sale and Purchase Agreement, he paid a further 15%, or $247,500, bringing his total downpayment to 20%. That 15% could come from CPF Ordinary Account and cash in any mix.

Running in parallel was Buyer's Stamp Duty, payable within 14 days of exercising the Option. Because he never trusts himself to compute this from memory, he used the stamp duty calculator to confirm the band-by-band figure the moment his agent quoted the price. Here is the working IRAS applies:

As a Singapore Citizen buying his first property, Boon Kiat paid 0% Additional Buyer's Stamp Duty, so his tax bill stopped at the $52,100 BSD. The common error he was warned about is stopping at the 4% band and forgetting the 5% that applies to any price above $1.5M. Both his BSD and downpayment could later be reimbursed from CPF OA, but the cash had to move first.

Put together, the money committed before construction properly began looked like this:

*With a 75% first housing loan, the downpayment is 25%, or $412,500. Minimum 5% ($82,500) must be cash; up to 20% ($330,000) can come from CPF OA. The bank loan of $1,237,500 covers the remaining 75%.

Boon Kiat had $110,000 in cash savings and $290,000 in his CPF OA. The maths worked: $82,500 cash for the booking, the balance of the downpayment and the $52,100 BSD funded largely from CPF, with a comfortable cash residual. Before he committed, he stress-tested the whole thing against his income using the affordability and loan calculator, because the loan size, not the sticker price, is what the bank actually approves.

Why the bank loan drips in, and why TDSR still bites at 4%

Here is the part that reassured him. The 75% bank loan does not disburse in one lump. It draws down progressively as construction certifies each stage: 10% at foundation, 10% at reinforced concrete framework, 5% each at partition walls, ceiling, wiring and car park stages, then a 25% tranche at Temporary Occupation Permit and a final 15% at legal completion. You pay interest only on what the bank has actually disbursed.

In practice, that meant his early instalments were tiny. At foundation stage the bank had disbursed only 10% of the price, so at his floating rate his monthly interest was a fraction of the eventual full instalment. This is the quiet advantage of the scheme: the heaviest cash flow is deferred to when you are closer to holding the keys.

But there is a trap in the reassurance. Even though headline rates were near 1%, his Total Debt Servicing Ratio was stress-tested against a 4% floor rate on the full eventual loan of $1,237,500, not the small disbursed amount and not the actual SORA rate. TDSR of 55% of gross monthly income is the ceiling, and the 4% floor is deliberately conservative. A low SORA does not raise your maximum loan. If you want to understand why a cheap rate does not translate into more borrowing power, our explainer on how TDSR and LTV affect your loan walks through the mechanics.

He chose a floating package pegged to 3-month SORA. During the construction years, when disbursements were small, he opted to service interest as it fell, keeping monthly outgoings low while the unit was not yet ready. He knew the full principal-plus-interest instalment would only kick in properly after the large TOP tranche, and he planned around that step-up rather than being surprised by it. Buyers weighing the fixed-versus-floating question in this rate environment should read our breakdown on how one family chose with 3M SORA at 1.19%.

The TOP tranche: where a comfortable buyer can suddenly feel poor

Two and a half years in, the project hit Temporary Occupation Permit and the single largest tranche fell due: 25% of the price, or $412,500. His bank loan and remaining CPF covered most of it, but this is the moment financial planners flag. Alongside the tranche came the practical costs that no progressive payment table shows you: legal fees, insurance, and renovation, which for a two-bedroom unit ran him around $55,000.

This is where Boon Kiat admits he got something wrong. He had budgeted almost to the dollar, leaving himself only about $12,000 of spare cash after the booking stage. When a delayed CPF nomination held up part of his OA transfer for a fortnight around the TOP payment, he had to scramble a short-term cash bridge from his parents. Nothing broke, but it was avoidable stress. Had he held the widely recommended $30,000 to $80,000 buffer above the calculator figure, the timing wobble would have been a non-event.

The framework Boon Kiat wishes he had started with

Stripped to its essentials, here is the transferable playbook any first-time new launch buyer can apply:

• Separate the two clocks. The stamp duty clock (14 days from exercising the Option) is unforgiving and cash-hungry. The construction clock (three to four years) is gentle at first and heavy at the end. Plan for both, not just the exciting one.
• Confirm the cash floor. At 75% LTV, only the 5% booking must be cash. On $1.65M that is $82,500. Everything else in the downpayment can lean on CPF OA, so know your OA balance to the dollar.
• Size the loan, not the price. TDSR at a 4% floor decides your ceiling. A 1.19% SORA is a bonus on monthly cost, not a lever on approval.
• Buffer the back end. The TOP tranche plus renovation is the crunch. Hold $30,000 to $80,000 in reserve above the schedule.

Boon Kiat's purchase was on a harmonised project, meaning its floor area was measured under the current rules that exclude voids like aircon ledges and planter boxes from saleable area, so he was paying progressively on genuinely liveable space. That also makes raw price psf comparisons across projects less reliable, especially against older resale stock measured the old way. Before comparing sizes or psf on any project, check which measurement convention it uses; for a worked example of a harmonised layout, see our Lucerne Grand review near Lakeside MRT in District 22.

Every new launch runs on its own construction calendar, and the right cash-and-CPF sequence depends on your OA balance, your income and the exact quantum you are eyeing.
