New Launch Condo Financing in Singapore (2026): Progressive Payment, IPA, and TOP Strategy

A new launch condo in Singapore is a S$1.5M–S$5M+ commitment with a three-week S&P clock, a multi-year construction tail, and a SORA-linked partial-drawdown loan that behaves nothing like a resale mortgage. The IPA, the loan tier, and the lock-in-to-TOP alignment decide the next 25 years of cashflow. Here is how Building Under Construction (BUC) financing works in 2026 and where the avoidable money is lost.

Progressive Payment Scheme: How the 5/15/10/30/30/10 Split Works

Singapore residential BUC projects sell on the Progressive Payment Scheme (PPS). The buyer pays the developer in instalments tied to construction milestones; the bank disburses the loan in matching tranches. Interest is charged only on amounts already drawn, so monthly instalments ramp gradually as the project completes.

PPS pays the developer in tranches synced to the building’s construction milestones. The bank’s draw schedule mirrors this, so interest costs ramp instead of starting at the full quantum on day one.

The first 5% is paid in cash + CPF at booking. The remaining 95% is the buyer’s loan + cash + CPF mix, drawn against the milestones above. Monthly interest scales as drawdowns accumulate, not from day one.

PPS vs Deferred Payment: Why DPS Is Off the Table for Residential

The Deferred Payment Scheme (DPS) let buyers pay 10–20% upfront and defer the rest until TOP. It was withdrawn for residential in 2007 to cool speculation. For new launches in 2026, residential PPS is the default; DPS-style structures appear only on commercial and select EC tail-end inventory.

PPS spreads loan disbursement across construction milestones — DPS concentrates it at TOP. Cashflow timing, interest accrual, and TDSR check all differ.

For most private property buyers the question is moot. A new launch in 2026 means PPS — the real choices are which lender to anchor with, the SORA spread tier, and how to plan the lock-in expiry against TOP.

The OTP Clock and Why an IPA Is Non-Negotiable

A new launch OTP commits a 5% booking fee — S$100K on a S$2M unit, S$250K on a S$5M unit. The buyer has approximately three weeks from OTP to exercise the S&P and pay the next 15%. Miss the window, and the booking fee is forfeited.

An In-Principle Approval is the bank’s written commitment to lend a specific quantum at a specific tenure, subject to valuation. It validates income, debt servicing under TDSR 55% (and MSR 30% if EC), and the MAS 4% stress test — before cash hits the developer’s account. Without one, the booking fee rides on assumptions.

The booking fee is committed at the showflat. The IPA should already be in hand.

New launch IPAs are particularly fragile. Valuations rely on developer pricing, not transacted comparables — if the unit prices above a bank’s PSF ceiling, the loan quantum drops and the buyer tops up the gap in cash. A single-bank IPA that "looks fine" can fail at another bank’s valuation desk on the same unit.

“Run parallel IPAs across three to five lenders before you sign the OTP. New launches valuation-shop badly — one bank’s S$1.5M ceiling can be another’s S$1.65M. The S$150K difference is the difference between exercising and forfeiting.”

TDSR, MSR, and the Loan-Tier Rate Game

Every new launch loan goes through the same MAS framework:

• TDSR 55%. Total monthly debt servicing (mortgage + car + cards + personal loans) cannot exceed 55% of gross income.
• MSR 30% (EC only). Mortgage instalment capped at 30% of gross income for ECs. Private condos and landed are not subject to MSR.
• 4% stress test. TDSR/MSR is recalculated against a 4.0% p.a. floor — not the live SORA rate. Qualifying today doesn’t mean passing the test.
• LTV 75% first loan, dropping to 45% on a second housing loan.

What most new launch buyers miss: banks tier their pricing by loan quantum. Same unit, same applicant, three different rates depending on the tier.

On a S$1.5M loan over 25 years, a 0.20% p.a. rate gap is roughly S$150 per month, or S$45,000 over the loan’s full life. Most new launch buyers fall into Priority or Jumbo bands and don’t know it — their relationship banker quotes the standard package because that’s the desk they sit on.

SORA Spreads on a Partially-Drawn BUC Loan

Singapore BUC packages are SORA-linked. Each tranche draws at the live 3M Compounded SORA + a bank spread fixed at signing. Spreads sit at roughly 0.20%–0.75% p.a. depending on quantum tier — the larger the loan, the tighter the spread.

Because outstanding balance ramps over construction — closer to 50% of full quantum for the first ~18 months — absolute interest cost in early years is smaller than on a fully-drawn loan. A 0.20% spread gap on a S$1.5M facility is a 0.20% gap on the average drawn balance, not the full quantum.

The decisive variable is lock-in alignment with TOP. A 2-year lock-in on a 4-year build reverts to board rate well before TOP — just as the largest tranches disburse. Picking a lender whose lock-in expires shortly after TOP preserves the option to refinance straight into a sharper post-TOP package.

TOP, Lock-In, and the Refinance Window

Temporary Occupation Permit (TOP) marks the unit habitable and triggers the next 5% disbursement. Most BUC lock-ins run 2–3 years from first disbursement, not from TOP — so depending on construction speed, lock-in may expire before, at, or after TOP.

Once expired, the package reverts to board rate — typically 3.50%–4.50%+ p.a., roughly 2x the live SORA-linked market. On a S$1.5M loan with three remaining disbursement years, that’s S$1,000+ per month of avoidable interest.

“The most expensive 18 months of a Singapore new-launch buyer’s loan is the period between lock-in expiry and TOP, sitting on a board rate. Repricing or refinancing inside that window is the highest-value mortgage action in the whole purchase journey.”

Use the refinance savings calculator 3–4 months before lock-in expiry to model the gap.

Five Expensive New-Launch Mistakes

• Booking without an IPA. Single-bank pre-approval isn’t enough — valuations differ and the booking fee evaporates if the loan can’t complete.
• Taking the relationship banker’s quote. Bank officers can only sell their bank, and often quote standard pricing when the loan qualifies for Priority, Jumbo, or Private Banking-grade tiers elsewhere.
• Lock-in that expires before TOP. Forces a board-rate reversion during the costliest disbursement window. Align expiry shortly after TOP.
• Optimising for headline spread alone. Construction timeline, lock-in alignment, and post-TOP refinance plan move more dollars than a 0.05% spread today.
• Ignoring second-purchase ABSD. Loans optimised for today’s rate often block a future decoupling or upgrade. Plan it before the IPA.

How a Nexus Broker Structures the Deal

Nexus is paid by the bank on disbursement — service is free to the borrower. Engagement runs against the OTP/S&P clock:

• Pre-OTP. 30-minute call. Map quantum, tenure, future-purchase plans, CPF, and TDSR/MSR headroom. Identify the loan tier.
• Day 1–2. Document checklist (payslips, CPF, NOAs, NRIC, existing loans). Parallel IPAs to 3–5 lenders matched to the tier.
• Day 3–5. Indicative offers in writing. Side-by-side: spread, lock-in (vs estimated TOP), legal subsidy, cashback, prepayment, sale clause.
• OTP signing. Chosen lender’s IPA already in hand. Coordinate Letter of Offer, valuation, conveyancing, CPF, and tranche disbursement through to TOP.
• Post-TOP. 4 months before lock-in expiry, refresh the market and place the refinance file with the right lender.
