7 Mistakes First-Time Condo Buyers in Singapore Keep Making

First-time condo buyers often carry HDB assumptions into a purchase with different loan, tax and resale rules. The seven mistakes below are expensive, but each has a check you can complete before paying an option fee.

1. Budgeting to the loan approval, not to cash flow

The bank approves what the 55% Total Debt Servicing Ratio allows: the most it will tolerate, with no view on how you live under it. A mortgage that consumes every approved dollar leaves nothing for rate rises (your repayment is stress-tested at a higher rate for a reason), job changes, or a child.

The check: build your own monthly number first (what you can pay while still saving) and shop within it. Treat the bank's figure as an upper bound you stay under on purpose. Use the worked condo affordability budget and check how TDSR limits the loan.

2. Forgetting the cash that is not the downpayment

The 25% downpayment (5% hard cash, the rest CPF-eligible) is only the visible cost. Around it sit Buyer's Stamp Duty (north of $44,000 on a $1.5 million purchase under the current BSD schedule), legal fees, valuation fees, and for private property, stamp duty is cash first, CPF reimbursement after. Add renovation and the first year of maintenance fees and the "hidden" column often exceeds $100,000.

The check: write the full cash schedule, every payment and its date, before you view a single unit. How CPF flows through a private purchase, including the accrued-interest meter it starts, is covered in our CPF guide.

3. Buying the showflat, not the stack

Showflats are optimised to sell; ID lighting and a 3.15m mock ceiling do not transfer to your unit. What transfers is the stack: orientation (west sun in Singapore will cook an afternoon living room), distance to the MRT at pavement level, rubbish chute and lift lobby placement, and what the facing plot is zoned to become.

The check: visit the actual site at noon and at 7pm. Pull the URA Master Plan for every empty plot within 200m. If buying resale, view the exact unit twice, once on a weekend. Still deciding between the two routes? We compare them dimension by dimension in new launch vs resale condo.

4. Ignoring the 4-year SSD clock

Since July 2025, selling a private residential property within 4 years attracts Seller's Stamp Duty of 16% / 12% / 8% / 4% by year of sale. A "we can always sell if it doesn't work out" plan now costs six figures in year one.

The check: buy only what fits your life for at least four years (family size, schools, commute). If your horizon is shorter, rent for now and buy when your plans firm up.

5. Treating the maintenance fee as a rounding error

$350–$500 a month is $4,200–$6,000 a year, every year, rising with the sinking-fund needs of an ageing development. Small developments with big facilities carry the highest per-unit fees: 50 units sharing a pool costs each owner far more than 500 units sharing one.

The check: ask for the current fee and the last two increases. For resale, ask about the sinking fund balance and any planned major works; a lift overhaul or façade repair can mean special levies.

6. Assuming the flat can be kept

Many first-time private buyers own an HDB flat and assume they can keep it as a rental. Legally, once past your Minimum Occupation Period, you can, but you will pay 20% ABSD on the condo (the full rate schedule and refund rules are in our ABSD guide) and carry both mortgages inside the same 55% TDSR. For most households the maths favours selling the flat, and the sequencing of that sale is its own decision; we work through it in sell first or buy first.

The check: price the keep-the-flat scenario fully (ABSD, both mortgages, rental yield after tax and vacancy) before you fall in love with it. It survives the spreadsheet less often than the coffee-shop version suggests.

7. Skipping the paper on a resale unit

Resale condos carry history: past en-bloc attempts, management disputes, unapproved renovations, tenancies that convey with the unit. None of this appears in the listing.

The check: have your lawyer review the last two AGM minutes of the MCST before you exercise the option. Ten pages of minutes tell you more about a development than any brochure: disputes, levies and leaks all live there. Our resale condo due-diligence checklist covers the title, approved plans, unit inspection and contract checks.

Use evidence, not the sales story

An asking price shows what a seller wants. A caveat shows what another buyer paid. The brochure shows the finished promise; AGM minutes show how owners run the estate. Check the source closest to the fact, and read our step-by-step guides before you commit.
