A buyer in his late 30s recently laid out his numbers in an online forum: a landed home in the low S$6 million range, roughly 3,600 sq ft of land, bought in a single name. He paid about 55% in cash, not by choice but because his income could not support borrowing the full 75%. His question was simple and worth answering properly: did he right-size this purchase, or could he have stretched further?
The useful thing about his case is that it exposes what landed affordability actually turns on. It is not the sticker price. It is the interaction between your loan-to-value (LTV) ceiling, how much cash that forces you to commit, the renovation reserve most buyers underestimate, and the liquidity you keep afterwards.
For a first residential loan with no outstanding mortgage, the maximum LTV is 75% of the property value or purchase price, whichever is lower (MAS rules). That is the ceiling. It is not a guarantee you will get there.
What you can actually borrow is set by the Total Debt Servicing Ratio (TDSR): your total monthly debt obligations cannot exceed 55% of gross monthly income, stress-tested at a medium-term interest rate floor (currently 4% for property loans under MAS guidance). For a single-name buyer on a S$6 million-plus purchase, the loan quantum needed to hit 75% is large, and TDSR often bites before the LTV cap does.
That is exactly what happened here. He could not borrow 75%, so he funded 55% in cash. The gap between what the LTV cap allows and what your income supports is the first number to model, because it determines how much liquid capital the purchase will consume before you have spent a cent on renovation.
His renovation estimates ran from S$300,000 for a basic job to S$500,000 for something more substantial, and S$900,000 to S$1 million if he pursued Addition & Alteration (A&A) works plus renovation and furnishings.
On a landed property, this is not a rounding error. A&A is effectively a partial rebuild, and on an older landed home it is frequently the difference between a house you tolerate and one you actually want to live in. But it is paid entirely in cash. No mortgage covers it. That means your renovation budget competes directly with your post-purchase liquidity buffer.
The planning error is treating renovation as an afterthought once the purchase price and stamp duty are settled. On a landed home it should be a line item you size before you commit to the house, because a S$700,000 swing between basic reno and full A&A can change whether the purchase is comfortable or precarious.
Buyer's Stamp Duty (BSD) alone on a S$6 million residential purchase runs to roughly S$260,000 under the current tiered schedule (IRAS). Additional Buyer's Stamp Duty (ABSD) does not apply here, as this is his sole residential property held in his name, but it is the kind of figure that reshapes a budget if it does.
After servicing the monthly mortgage, he has about S$9,000 in cash each month. But he flagged the correction himself: after IRAS obligations, true take-home is closer to S$6,000 to S$7,000.
That distinction matters more than the headline. A S$9,000 buffer looks comfortable. A S$6,000 buffer, on a household with one young child, funding an ongoing landed-property maintenance load, is workable but not generous. Landed homes carry running costs that condominiums bundle into a maintenance fee: roofing, drainage, exterior painting, landscaping, and eventual structural upkeep. Budget for them as a recurring line, not a surprise.
His household is structured to absorb this. His wife's income and the rental income from a second property cover household expenses and service that property's mortgage. So the landed home sits on his income alone, and the S$6,000 to S$7,000 is genuinely his to allocate. That is a defensible structure, provided both income streams hold.
After paying for the house and assuming the full S$900,000 to S$1 million A&A path, he expects to retain around S$1 million in stocks. He asked whether that is enough, or whether he was too conservative and could have bought bigger.
On a purchase of this size, S$1 million is a reasonable buffer, not an excessive one. It is roughly what you want sitting behind a single-income mortgage on a multi-million-dollar asset, given three exposures: interest rates resetting higher when his fixed or floating package reprices, a landed maintenance event, and any interruption to either household income stream. Stocks are liquid but volatile; a buffer you might have to sell into a down market is worth less than its face value in a crisis.
So the answer to "could I have gone bigger" is: only if you were willing to run that buffer down, and on a single name at this price, that is the wrong trade. He right-sized it.
One factor sits underneath all of this and is easy to skip. If you are committing this much cash and running a lean buffer, the location has to protect your equity.
Singapore's East is currently characterised as the country's most resilient landed corridor (EdgeProp, July 2026). Resilience here means values that hold through softer cycles and recover faster, which matters directly to a buyer whose net worth is concentrated in one property. If you are choosing between a larger house in a thinner market and a right-sized house in a corridor with durable demand, the latter does more to protect the capital you have locked in.
For a landed purchase, work backwards from cash and income, not from the asking price:
The headline price tells you almost nothing. These five numbers tell you whether you can actually afford the house.
Upgrading in your 40s or 50s still works if you are already financially secure, because the amount a bank will lend depends on age plus loan tenure, not just income. If your age plus tenure exceeds 65, or tenure exceeds 35 years for private property or 30 years for HDB, the maximum loan-to-value drops from 75% to 55%, meaning you must fund 45% of the price from cash and CPF instead of 25%. The alternative is keeping a shorter tenure to stay at 75% LTV, but that means higher monthly payments, so the real decision is whether you can afford the bigger downpayment or higher payments while staying on track for retirement.

HDB calculates EHG based on average gross monthly household income over a 12-month window, but each person's income is averaged only over the months they actually worked, not spread across all 12 months. This means short stints of part-time or contract work count at full monthly value rather than being diluted, which can push a household into a lower income band and significantly reduce the grant amount.
