The condo buying process Singapore buyers follow can feel opaque the first time, full of acronyms and deadlines that arrive faster than expected. Yet the journey from your first serious offer to the day you collect your keys is actually a well-worn path with clear milestones. Understanding each stage in advance means you can budget, line up your lawyer and financing, and avoid the panic of a deadline you did not see coming. This guide explains the sequence in plain terms, whether you are buying a resale private condo or a completed new launch, so you know what happens, who does what, and where the money moves.
Before You Make an Offer: Getting Ready
The smoothest purchases start long before the paperwork. Getting your finances and paperwork in order first gives you room to act with confidence when the right unit appears.
- Confirm your budget and borrowing power. Speak to your bank or a licensed mortgage adviser and obtain an in-principle approval so you know your realistic loan headroom. Loan limits and the rules around them change, so check current requirements with MAS and your bank.
- Understand the cash and CPF split. Work out what you can pay in cash, what your CPF Ordinary Account can cover, and what you need to borrow. Verify current CPF usage rules with the CPF Board rather than assuming.
- Budget for the extras. Beyond the price there is stamp duty, legal fees and other costs. Confirm each current figure with IRAS and your lawyer instead of relying on estimates.
- Engage professionals. Line up a conveyancing lawyer and, if you are using one, a CEA-registered agent whom you have checked on the CEA Public Register.
Doing this groundwork means that when you find a unit, you are ready to move without scrambling.
Stage One: The Option to Purchase
Once you and the seller agree on a price, the process formally begins with the Option to Purchase, or OTP. This is a legal document in which the seller grants you, for a fee, the exclusive right to buy the unit at the agreed price within a fixed option period. You pay an option fee to secure it, and during that window the seller cannot sell to anyone else.
The OTP is a binding legal instrument, so this is the moment to have your conveyancing lawyer involved and to make sure your financing is confirmed. Because the option fee, deposit percentages and stamp duty all depend on current rules and your circumstances, treat any figure quoted to you as something to verify with your lawyer, your bank and IRAS. Do not sign under time pressure without understanding what you are committing to.
Stage Two: Exercising the Option
If you decide to proceed, you “exercise” the OTP within the option period. In practice this means signing the option document and paying the balance of the deposit, which turns the option into a firm contract to buy. For a resale condo the OTP itself usually forms the contract; for a new launch you sign the developer’s Sale and Purchase Agreement. Your lawyer prepares and checks these documents and lodges a caveat to register your interest in the property.
If you choose not to exercise the option, you generally forfeit the option fee and walk away, which is why the decision to grant an OTP should never be casual. This stage is legal in nature, so rely on your lawyer rather than general guidance, and defer to the SLA and the Council for Estate Agencies on the formalities where relevant.
Stage Three: Financing, CPF and Stamp Duty
With the contract firm, the money side moves into gear. Your bank formalises the housing loan and issues a letter of offer, which you sign after reading the terms. If you are using CPF savings, your lawyer coordinates the CPF Board withdrawal for the portions the rules allow. Around this time the relevant stamp duty falls due within the statutory deadline, and your lawyer typically handles the payment to IRAS on your behalf.
Every number here, the loan quantum, the CPF amount and the stamp duty, is governed by rules that change and vary by buyer, so confirm current figures directly with MAS, your bank, the CPF Board and IRAS. This is general information, not financial or tax advice, and a short conversation with your lawyer or adviser is worth far more than a guessed figure.
Stage Four: Completion and Getting Your Keys
Completion is the finish line, the date set in the contract when the balance of the price is paid and legal ownership transfers to you. In the run-up, your lawyer conducts the final legal searches, prepares the transfer documents and liaises with the seller’s lawyer and the bank so that funds move on the day. On completion, the seller hands over vacant possession and you receive the keys.
For a resale purchase, completion usually falls within a few months of exercising the option. For a new launch bought off the plan, payment and completion are staged over the construction period, and legal completion follows once the development is finished and the relevant permits are issued. Either way, do a final inspection at handover and note any defects to raise with the seller or developer.
The Journey at a Glance
It helps to see the milestones side by side, with the main task and the typical lead player at each stage. Timings depend on the transaction, so treat these as a general map rather than fixed durations.
| Stage | What happens | Who leads |
|---|---|---|
| Preparation | Budget, in-principle approval, engage lawyer | You, bank, agent |
| Option to Purchase | Pay option fee, receive the OTP | You and seller |
| Exercise the option | Sign, pay deposit, lawyer lodges caveat | Your lawyer |
| Financing and duties | Loan, CPF withdrawal, stamp duty paid | Bank, CPF Board, IRAS |
| Completion | Balance paid, ownership transfers, keys handed over | Lawyers and banks |
Keep a simple checklist against these stages and you will always know what comes next.
Who This Guide Helps and What to Remember
This walkthrough suits first-time private buyers, HDB upgraders moving into a condo, and anyone who wants to feel prepared rather than reactive. The exact steps can vary between a resale unit and a new launch, and between banks and law firms, so use it as a framework and confirm the specifics for your own purchase.
Property is a significant financial and legal commitment. Nothing here is financial or legal advice; it is general information. For current rules, figures and eligibility, defer to HDB, URA, CPF Board, IRAS, MAS and the SLA, engage a conveyancing lawyer, and work only with a CEA-registered agent you have verified on the CEA Public Register.
