A Good Class Bungalow is the most coveted address in Singapore residential property. When clients ask me how much they actually need to buy one, the honest answer is almost always: considerably more than the headline price suggests. The GCB market sits at the intersection of strict eligibility rules, conservative bank lending, substantial stamp duties, and buyer profiles who are, more often than not, writing very large cheques with minimal leverage. Let me walk you through the real numbers on a S$10 million purchase.
Who Can Even Buy a GCB? Eligibility First
Before financing enters the conversation, eligibility does. GCBs sit within one of 39 gazetted GCB Areas, carry a minimum plot size of roughly 1,400 square metres (about 15,070 square feet), and are capped at two storeys plus attic or basement with tight site coverage controls. More importantly, mainland landed property in Singapore is a Singapore Citizens-only market. Permanent Residents and foreigners cannot purchase a GCB or any other mainland landed home without rare, discretionary approval from the Land Dealings Approval Unit under SLA, which is almost never granted for GCBs. If you hold a PR or foreign passport, Sentosa Cove is the one location where SLA approval for landed homes is routinely possible, but no GCBs exist there. Confirm current landed eligibility rules with SLA before proceeding.
The Financing Reality: Why 75% LTV Is Often Theoretical
MAS rules cap the first housing loan at 75% loan-to-value, requiring a minimum 25% downpayment (at least 5% in cash, with the remainder in cash or CPF). On a S$10 million property that means a minimum S$2.5 million down, of which at least S$500,000 must be cash.
In practice, however, banks apply considerably more conservative underwriting to trophy landed assets at this price point. Lenders are acutely aware of liquidity risk on a property with a very thin buyer pool, and internal credit policies frequently result in effective LTVs of 50% to 60% or lower on GCBs. I tell my clients to treat the 75% cap as a ceiling, not an expectation, and to stress-test their finances assuming a loan of 50% or even less. Always confirm actual LTV appetite directly with your preferred private bank or mortgage specialist before signing any OTP.
TDSR and the Income Equation
Every borrower in Singapore is subject to the Total Debt Servicing Ratio framework: total monthly debt obligations cannot exceed 55% of verified gross monthly income. Banks do not use the promotional rate to assess this; they stress-test at a medium-term floor rate of approximately 4% per annum (confirm the current floor with your bank, as MAS guidance can be updated). This has a material effect on the income you need to qualify.
Worked Example: S$10 Million GCB, Singapore Citizen, First Property
| Item | Amount (indicative) | Notes |
|---|---|---|
| Purchase price | S$10,000,000 | Illustrative only; GCB prices vary widely |
| Indicative loan (50% LTV) | S$5,000,000 | Banks may lend less; confirm with lender. Regulatory cap is 75%. |
| Cash / CPF downpayment | S$5,000,000 | At 50% LTV; minimum 5% (S$500k) must be cash |
| Buyer's Stamp Duty (BSD) | ~S$544,600 | See calculation below; verify with IRAS BSD calculator |
| ABSD (1st residential property, SC) | S$0 | 0% for Singapore Citizen on first purchase; confirm with IRAS |
| Estimated monthly instalment (30-yr, 4% stress rate) | ~S$23,860 | Indicative; actual rate and tenure will differ |
| Gross monthly income needed (TDSR 55%) | ~S$43,400+ | Assumes no other debt; other obligations reduce this headroom fast |
| Total upfront capital required | ~S$5,544,600+ | Down plus BSD; legal fees, agent fees additional |
How BSD Is Calculated on a S$10 Million Purchase
Buyer's Stamp Duty is progressive. The current rate tiers (confirm with IRAS, as rates are subject to change) work as follows for residential property:
- First S$180,000: 1% = S$1,800
- Next S$180,000: 2% = S$3,600
- Next S$640,000: 3% = S$19,200
- Next S$500,000: 4% = S$20,000
- Next S$1,500,000 (up to S$3m): 5% = S$75,000 (on the portion from S$1.5m to S$3m)
- Remaining S$7,000,000 (above S$3m): 6% = S$420,000
That brings BSD to approximately S$539,600 to S$544,600 on a S$10 million purchase. Always run your exact figure through the IRAS stamp duty calculator at iras.gov.sg before exchange of contracts.
What If It Is Your Second or Third Property? ABSD Matters Enormously
For a Singapore Citizen buying a second residential property, ABSD is currently 20% of the purchase price. On S$10 million, that is S$2,000,000 payable in addition to BSD. A third or subsequent property attracts 30%. For Permanent Residents the rates are 5% on a first purchase and 30% on a second. Foreigners pay 60% on any residential purchase, and as noted above, are in any case generally ineligible for mainland landed. A living trust purchase incurs ABSD (Trust) at 65%. An entity or company faces ABSD (Entity) at 65% plus an additional non-remittable component for housing developers. These rates have changed multiple times with successive cooling measures; always confirm the current schedule with IRAS before transacting.
The Honest Reality: Most GCB Buyers Use Very Little Leverage
The worked example above uses 50% LTV, which is already on the higher end for this asset class. In my experience with HNW buyers in this segment, many finance no more than 30% to 40% of the purchase price, and a meaningful number pay entirely in cash. The income-to-TDSR calculation becomes less binding when leverage is low, but the absolute quantum of equity required remains enormous regardless. A buyer paying 30% down on S$10 million still needs S$3 million in equity upfront, plus over S$500,000 in BSD, and potentially S$2 million in ABSD if it is a second property. That is S$5.5 million in committed capital before a single tile is laid.
What My HNW Clients Look for in a GCB
Beyond the numbers, buyers at this level are highly specific about product. In my experience, the most sought-after GCBs offer generous single-level living, ideally 2,000 square feet or more on one floor, with the kind of privacy and ceiling heights that a landed plot in Districts 10 or 11 can deliver. Many of my clients specifically favour the Orchard precinct within D10 for its connectivity alongside a quiet residential feel. The pool of true GCBs meeting these criteria in any given year is very small, which is precisely why specialist representation matters.

A Note on Professional Advice
Every figure in this article is illustrative and based on rules and rates current as of early 2026. BSD and ABSD schedules, LTV caps, and TDSR parameters are all subject to change with cooling measures or MAS guidance. Before you commit to an OTP, please verify stamp duty with IRAS, lending appetite with your bank or private banker, and landed eligibility with SLA.
