Buying your first home in Singapore comes down to six practical steps: work out how much you can borrow and afford, decide between HDB and private, secure an HDB Flat Eligibility (HFE) letter or a bank In-Principle Approval, budget for the downpayment and Buyer’s Stamp Duty, check which CPF Housing Grants you qualify for, then sign the Option to Purchase and complete the legal process. Take them in order and you’ll avoid the most common (and most expensive) surprises.
💰 Step 1: Work out your real budget
Before you fall in love with a listing, anchor yourself to the numbers. Two rules cap how much you can borrow. For HDB flats and Executive Condominiums, the Mortgage Servicing Ratio (MSR) limits your monthly home-loan repayment to 30% of your gross monthly income. For bank loans on any property, the Total Debt Servicing Ratio (TDSR) caps all your monthly debt repayments — car loans, credit cards, everything — at 55% of gross income.
On top of that, the first housing Loan-to-Value (LTV) limit is 75%, so you fund at least 25% of the price yourself through a mix of cash and CPF. A handy way to pressure-test all this is the HDB affordability calculator, which folds MSR, LTV and your CPF into one number you can actually act on.
🏠 Step 2: HDB or private?
This is the fork in the road. An HDB flat is more affordable, comes with grant support, and lets you take an HDB concessionary loan where the downpayment can be paid fully from your CPF Ordinary Account. A bank loan, by contrast, requires at least 5% of the price in cash. The trade-off with HDB is the Minimum Occupation Period (MOP): 5 years for standard flats (10 years for new Plus and Prime flats) before you can sell or rent out the whole flat.
Within HDB you’ll also choose between BTO and resale. A BTO is a new, subsidised, balloted flat with a roughly 3–4 year wait and income-ceiling rules. A resale flat lets you move in quickly and pick the exact location, size and remaining lease, though you may pay above valuation. If a condo is on your radar, run the figures through the condo affordability calculator first — private property carries Buyer’s Stamp Duty on a higher price and no MSR cap, but TDSR still applies.
📄 Step 3: Get your HFE letter or In-Principle Approval
Don’t shop blind. Any HDB flat buyer needs an HDB Flat Eligibility (HFE) letter — it confirms your eligibility to buy, the grants you can receive, and (if you take an HDB loan) your loan amount, all in one document. If you plan to use a bank loan instead of an HDB loan, also request an In-Principle Approval (IPA) from the bank, which gives its indicative loan amount based on your income and existing debts. (Buying private? You’ll rely on the bank’s IPA.)
Either way, you walk into negotiations knowing your ceiling. That stops you from committing to an Option to Purchase you can’t finance.
🧾 Step 4: Budget for the downpayment and stamp duty
Two big cash-and-CPF outflows hit early. First, the downpayment: with 75% LTV you cover the remaining 25%, and for a bank loan at least 5% of that must be in cash. Second, Buyer’s Stamp Duty (BSD), which everyone pays — it’s progressive on the purchase price. Use the Buyer’s Stamp Duty calculator to get the exact figure for your price.
Here’s a worked example. Say you and your spouse buy a resale flat for $500,000 with a bank loan and you’re both Singapore Citizens buying your first home (so no Additional Buyer’s Stamp Duty applies). At 75% LTV the bank lends $375,000, leaving $125,000 as downpayment. Of that, at least 5% of the price — $25,000 — must be paid in cash, and the rest can come from CPF. You’ll also owe BSD on the $500,000 on top, payable from cash or CPF. Plug your own loan into the mortgage calculator to see the monthly repayment and make sure it sits comfortably under the MSR or TDSR cap.
🎁 Step 5: Check your first-timer CPF Housing Grants
First-time buyers may qualify for CPF Housing Grants that meaningfully lower what you pay. The amount depends on your household income, the flat type, and whether you’re buying BTO or resale, so treat them as a discount to confirm — not a fixed number you can assume.
- Your HFE letter spells out exactly which grants you’re eligible for and how much.
- Resale buyers and BTO buyers have different grant schemes, so check before you commit.
- Grants reduce the cash and CPF you need up front, which can change the budget from Step 1.
✍️ Step 6: Option to Purchase, legal work and completion
Once you’ve agreed on a flat, the seller grants you an Option to Purchase (OTP) — you pay a small option fee to reserve it, then a further sum when you exercise the option. After that, your conveyancing lawyer (or HDB, for HDB transactions) handles title checks, the loan paperwork and the disbursement of your CPF and cash.
At completion, the balance is paid, the keys change hands, and the property is legally yours. One thing to keep in mind for later: there’s no capital gains tax when individuals sell their own property, but Seller’s Stamp Duty applies if you sell within the holding period — so buy with the intention to stay put.
🚀 Ready to run your numbers?
The fastest way to turn this plan into a real budget is to start with the HDB affordability calculator, confirm your Buyer’s Stamp Duty, and then size your monthly repayment in the mortgage calculator. Do that before you view a single flat, and every step after will be far less stressful.
