The mistakes that cost Singapore home buyers the most in 2026 are rarely about taste. They are about cash, timing and tax: committing before the loan is confirmed, borrowing to the limit while rates are low, and owning two homes for one day too long. Almost all of them can be avoided with a calculator and a week of patience.

At a glance

  • Budget for more than the downpayment. A S$1.5 million first home needs about S$420,000 of your own money before legal fees and renovation, and at least S$75,000 of it must be cash.
  • Get your loan approval in principle before you pay an option fee or booking fee. If you walk away, you lose money.
  • Test your mortgage at 3.5–4%, not today’s rates. Packages are about 1.5–2.2% now, but SORA alone was above 3.5% in 2023.
  • If you will own two homes, even for a short time, check ABSD (20% for a citizen’s second home) and the 4-year Seller’s Stamp Duty before you sign.
  • Inspect for defects within the 12-month defects liability period on a new home. A resale home comes “as is”.

Mistake 1: budgeting for the downpayment only

Most first-time buyers know the loan covers 75% at most. Fewer add up everything else. Say you are a Singapore Citizen buying your first home, a S$1.5 million condo, with a bank loan:

ItemAmountHow you can pay
Minimum cash downpayment (5%)S$75,000Cash only
Rest of the downpayment (20%)S$300,000Cash or CPF Ordinary Account (OA)
Buyer’s Stamp DutyS$44,600Due within 14 days; CPF OA can be used
ABSD (first home, citizen)S$0—
Total before fees and renovationS$419,600

The loan limits come from MAS, and the BSD rates (1% rising to 6% above S$3 million) and the 14-day deadline come from IRAS. CPF Board lets you use OA savings for the downpayment, stamp duty and legal fees, but it does not pay the minimum 5% cash.

Then there is the valuation gap. Banks lend on the lower of the price or the valuation, and CPF usage is capped the same way unless you have set aside your Basic Retirement Sum. If you pay S$1.5 million for a unit valued at S$1.45 million, the loan falls to S$1,087,500 and your share rises by S$37,500.

After you move in, the bills continue: maintenance fees, renovation and property tax. Property tax is modest for an owner-occupier (S$960 a year on an annual value of S$36,000, before rebates). It rises to S$4,800 if you move out and rent the unit out.

Mistake 2: committing before the loan is confirmed

An option to purchase (OTP) is cheap to get and expensive to drop. On a private resale home, you usually pay about 1% for the option. Under the standard CEA template you get two weeks to exercise it, and you forfeit the option money if you do not. On a new launch you pay a booking fee of 5–10%. According to URA’s home buyers’ guide, the developer may keep 25% of that fee if you do not exercise. On a S$1.5 million unit with a 5% booking fee, that is S$18,750.

So get a bank’s approval in principle (IPA) first, ideally with an indicative valuation. For an HDB flat, you need a valid HDB Flat Eligibility (HFE) letter before you take an OTP. Between the IPA and the actual loan, do not change jobs, take a car loan or miss card payments. Your total debt servicing ratio (TDSR) is measured on the day the bank decides.

Compare packages yourself or through a broker. The seller’s agent is paid by the seller, and the developer’s agents represent the developer. Under CEA rules, an agent cannot collect commission from both sides of a deal, and there are no fixed commission rates. Everything is negotiable, so put it in writing.

Mistake 3: borrowing to the limit because rates are low

Three-month compounded SORA was about 1.2% on 1 October 2026. Bank packages rose after the US Federal Reserve raised rates on 16 September 2026. Floating packages are now about 1.5–1.8% and fixed packages about 2.0–2.2% (The Business Times, 2 October 2026; CNA, 18 September 2026). In 2023, SORA was above 3.5%. Take a S$1,125,000 loan over 30 years (75% of S$1.5 million):

Interest rateMonthly instalment
1.8% (top of the floating range, Oct 2026)S$4,047
2.1% (a typical fixed package, Oct 2026)S$4,215
3.8% (2023-style rates)S$5,242
4.0% (the MAS stress-test rate)S$5,371

If rates return to 2023 levels, that is S$1,195 a month more than at 1.8%. The TDSR rule already tests you at 4%: all your debt repayments must stay within 55% of gross income. This loan needs at least S$9,765 a month if you have no other debts. But passing TDSR is the legal maximum, not a comfortable level. Run your own numbers with the Propwise mortgage calculator, and read our guide to TDSR and the 3-3-5 affordability rule.

Mistake 4: getting the ABSD timing wrong when you upgrade

ABSD depends on what you own on the day you buy. A citizen pays 0% on a first home, 20% on a second and 30% on a third. Permanent residents pay 5% / 30% / 35%. Joint buyers pay the highest rate among them, on the whole price.

Upgraders get caught in three ways:

  • Singles who buy before selling. A single citizen who still owns an HDB flat and buys a S$1.5 million condo pays S$300,000 in ABSD, with no refund. (The only exception is citizens aged 55 and above buying a lower-value home.) To avoid it, contract the sale of the first home before you accept the OTP on the second.
  • Married couples who miss the deadline. A couple with at least one citizen pays the ABSD upfront, then gets it refunded only if they sell the first home within six months. For a completed home, the six months run from the purchase. For a new launch, they run from TOP. There are no extensions.
  • Owners of HDB flats or ECs who have not met the minimum occupation period (MOP). You must meet the MOP before you can buy private property at all. For Plus and Prime flats, the MOP is 10 years, not 5.

“Decoupling” or 99-to-1 schemes are not automatically illegal. But IRAS can disregard an arrangement made to reduce ABSD, with a 50% surcharge. By April 2024 it had found avoidance in 166 of 187 cases it reviewed. Get specific legal advice before you try one.

Mistake 5: forgetting the four-year SSD

For homes bought from 4 July 2025, Seller’s Stamp Duty applies if you sell within four years: 16% in year one, then 12%, 8% and 4%. Sell that S$1.5 million condo 18 months after you buy it and you owe S$180,000. Buyers rarely plan to sell early. But job moves, a second child or a divorce do happen. If there is a real chance you will move within four years, renting may cost less. Our rent-or-buy guide shows the maths.

Mistake 6: buying the showflat, not the unit

URA’s guide spells out what showflats can and cannot show. Wallpaper, lighting, curtains and loose appliances are often decoration only. Some walls may be left out “to facilitate visitor movement”. The unit you buy may also differ from the show unit. Read the floor-area breakdown: the strata area you pay for can include air-con ledges and void space. Check how parking lots are allocated if there are fewer lots than units. Ask for any freebies (a washing machine, a cooker) in writing. And a “blank cheque” given at a launch to show interest is not a commitment to buy. Ask for it back if you do not go ahead.

Mistake 7: following the crowd

Full car parks and “last few units” talk at a launch are marketing, not market data. Wait 48 hours before you commit. Then check what similar units actually sold for on URA’s private transaction search, or HDB resale prices on data.gov.sg.

The 2026 market gives you no reason to panic-buy. Private prices rose a modest 1.4% in Q3 (flash estimate), and HDB resale prices dipped for a third straight quarter. The 2026 Government Land Sales programme confirms 9,320 private homes, more than 50% above the 10-year average.

Mistake 8: ignoring the lease and the exit

Before you buy, ask two questions. Who will buy this home from you in 15 years? And can you use your CPF for it? If the remaining lease does not cover the youngest buyer to age 95, CPF usage is pro-rated. The next buyer of an ageing flat faces the same limit, so fewer people can afford it. Do not pay extra for en bloc potential. Lower consent thresholds for older condos are on the way, but no start date has been announced, and a sale still needs a buyer at the right price. For new HDB flats, check the classification: Plus and Prime flats carry a 10-year MOP, can never be rented out whole, and must repay a subsidy recovery of 6–14% of the resale price or valuation when sold.

On a new launch, the developer must fix defects that appear within 12 months of vacant possession (or of the TOP notice, if earlier), and must make them good within one month of your notice. Book a professional inspection early in that window, rather than discover leaks after it ends. Our guide to developer defects explains the process. A resale home has no defects liability period, so inspect before you exercise the OTP. Let your lawyer check the title, any caveats and government schemes that affect the property.

Bottom line

Good home purchases are boring. Know your full cash need, get the loan approved first, borrow less than the maximum, and map out ABSD and SSD before you sign anything. Above all, do not let a sales gallery set your timetable. Our 10-step buying process puts these checks in order.
