This calculator models a Dunearn Green purchase end to end under the Progressive Payment Scheme: your loan-to-value tier and downpayment, the stamp duty for your buyer profile, and the monthly instalment at every construction stage as the bank disburses the loan progressively — the mechanism explained on the payment scheme page.

Standard PPS under the Housing Developers Rules; instalments are amortised on the cumulative disbursement over the full term. The 5% booking fee is strictly cash; the balance downpayment absorbs the early construction stages the loan does not cover. Both duties are payable within 14 days of exercising the Option. Rates per IRAS/MAS as of July 2026 — indicative only, confirm with your bank. The confirmed Dunearn Green schedule is set out in the Sale & Purchase Agreement at launch.
The shape matters as much as the total. Cash and CPF cover the downpayment tier your LTV allows, then the bank disburses in step with certified construction — so instalments start small and step up over a build that typically runs three to four years to TOP. Buyers servicing an existing loan see the difference vividly here: at 45% LTV the upfront funds more than double, which is why upgraders sequence a sale before exercising.
The ABSD line often exceeds every other cost combined for second-property and foreign buyers — the stamp duty guide covers the remission and refund rules in detail, including the married-couple provisions. Size your loan ceiling first with the TDSR calculator, then book an appointment and the team will map this schedule against the actual launch timeline.
