For Singapore citizens and PRs buying a private residential property like Koon Seng House, the standard minimum down payment under the 75% loan-to-value (LTV) limit is 25% of the purchase price. The first 5% is paid in cash at booking when the developer issues the Option to Purchase (OTP). The remaining 20% is payable when the OTP is exercised, sourced from cash and/or CPF Ordinary Account. Foreigners follow the same 25% down payment structure but cannot use CPF. Speak to our licensed agent for an individual TDSR calculation.
ABSD on a private residential purchase in Singapore including Koon Seng House is 0% for a Singapore citizen's first property, 20% for a citizen's second, and 30% for a third or more. PRs pay 5% on their first property and 30% on their second. Foreigners pay 60% on any property. ABSD remission is available for couples where one spouse is a Singapore citizen, subject to conditions including selling existing properties within 6 months. Final rates are set by IRAS at the time of purchase.
BSD on Koon Seng House is calculated on a tiered sliding scale set by IRAS: 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000, 4% on the next S$500,000, 5% on the next S$1.5M, and 6% on the amount above S$3M. BSD is payable to IRAS within 14 days of signing the purchase contract. Any Additional Buyer's Stamp Duty (ABSD) is on top of BSD, not instead of it.
To book a unit at Koon Seng House: (1) Register your interest via the enquiry form on this page. (2) Our agent sends the latest price list, floor plans, and unit availability. (3) Confirm your selection and submit the 5% Option Fee (cheque or PayNow). (4) The developer issues the Option to Purchase (OTP), with the Sale & Purchase Agreement typically delivered within 14 days. (5) Exercise the OTP within roughly 3 weeks of receiving the S&PA by paying the remaining 20% (balance of the 25% down payment) and signing the agreement. The full process from booking to S&PA signing usually takes 3 to 6 weeks.
Monthly maintenance fees at Koon Seng House are payable to the Management Corporation Strata Title (MCST) once the development is completed. Across Singapore, mass-market new launches typically fall between S$300 and S$800 per month for a 3-bedroom unit, while luxury developments with extensive facilities (concierge, multiple pools, sky lounges) frequently exceed S$1,500 per month. Exact fees depend on unit share value, development size, and facility scope. The first year's contribution is usually paid in advance at completion. Our agent provides the exact MCST budget for Koon Seng House once the developer publishes it.
Yes. For Koon Seng House, eligible Singapore citizens and PRs can fund the purchase with a combination of cash, CPF Ordinary Account (OA) funds, and a bank loan, subject to the Total Debt Servicing Ratio (TDSR) cap of 55% of gross monthly income. The standard split is 5% cash + 20% CPF or cash for the down payment, with the remaining 75% via a bank loan. MAS allows a maximum private-property loan tenure of 35 years, but tenures over 30 years (or that extend past age 65) face reduced LTV limits. Foreigners cannot use CPF and must rely on cash plus a bank loan.
Buying Koon Seng House as a new launch differs from a resale condo purchase in three main ways. First, payment is progressive: instead of paying the full price upfront, payments are staged (5%, 20%, then construction-milestone instalments). Second, new launches ship with the developer's full fittings, warranty, and current building specifications. Third, while Buyer's Stamp Duty and ABSD apply identically to both, new launches give early-bird buyers access to preferred units, floors, and views at the official launch price. Resale condos move faster (immediate possession) but lack the construction-period payment flexibility.
