How long does it take to buy a condo in Singapore? The full timeline

By Winfred Quek · 10-minute read · Last reviewed May 2026

Quick answer: A resale condo purchase in Singapore typically takes 10 to 12 weeks from exercising the Option to Purchase (OTP) to completion and key collection. Add a few weeks before that for viewing, negotiation and securing financing. The OTP exercise window for a private resale is usually 14 to 21 days from the OTP date, with a 1% option fee and roughly 4% on exercise. A new launch (Building Under Construction, or BUC) follows a different path: you book a unit, sign the Sale & Purchase Agreement, and pay in stages over two to four years until the project obtains its Temporary Occupation Permit.

Key Takeaways

• A resale condo runs roughly 10 to 12 weeks from OTP exercise to keys; sort financing before you view, not after.
• The private resale OTP carries a 1% option fee, with about 4% more due on exercise inside a 14 to 21 day window.
• Buyer's Stamp Duty and any ABSD fall due 14 days after the OTP is exercised, in cash or CPF, never financed by the loan.
• A new launch (BUC) replaces the OTP with a Sale & Purchase Agreement and pays out over two to four years on the Progressive Payment Scheme.
• The single biggest delay risk on a resale is a low bank valuation that opens a cash-over-valuation gap.

Buyers ask me this question constantly, and the honest answer is: it depends on whether you are buying resale or new. The two paths have almost nothing in common in terms of timeline. A resale condo is a fast, defined transaction measured in weeks. A new launch is a multi-year commitment where you pay as the building rises. Confusing the two leads to cash flow surprises, so let us walk through both properly.

How Long Does a Resale Condo Purchase Take?

For a completed resale condo, the clock that matters starts when you exercise the Option to Purchase. Before that, there is an unbounded period of viewing and negotiation that depends entirely on you. Once you commit, the process is predictable.

Here is the realistic week-by-week sequence for a private resale.

Before week 1 -- Preparation: Get an Approval-in-Principle (AIP) from a bank so you know your loan ceiling. View units, negotiate price, agree terms with the seller.

Day 0 -- OTP granted: You pay the seller a 1% option fee. The seller grants you the OTP, giving you the exclusive right to buy at the agreed price within the stated window, usually 14 to 21 days.

Days 1 to 14 -- Due diligence and financing: Appoint a conveyancing lawyer. The bank arranges a formal valuation. You finalise your loan offer. This is the window to confirm the bank's valuation supports the price.

Day 14 to 21 -- Exercise the OTP: You sign and return the OTP, paying roughly a further 4% of the price. The 1% plus 4% together make up the standard 5% deposit. Within 14 days of exercising, Buyer's Stamp Duty and any ABSD must be paid.

Weeks 3 to 10 -- Conveyancing: Your lawyer conducts title searches, lodges a caveat, raises legal requisitions to government departments, and coordinates the bank loan and CPF withdrawal.

Weeks 10 to 12 -- Completion: The balance of the purchase price is paid, the title transfers, and you collect the keys. Completion is typically set 8 to 12 weeks after OTP exercise.

So from the day you exercise to the day you hold keys is around 10 to 12 weeks. The negotiation and financing phase before that can be a single weekend if you are decisive and prepared, or several months if you are still searching.

What Does the New Launch (BUC) Timeline Look Like?

A new launch condo bought from a developer is a completely different animal. There is no OTP in the resale sense and no fixed completion date measured in weeks. Instead, you buy a unit that may not yet exist, and you pay in stages as the developer builds it.

According to the URA, projects sold before completion are governed by the standard form Sale & Purchase Agreement prescribed under housing developer rules. The sequence runs like this:

Booking day: You pay a booking fee (commonly 5% of the price) and are issued an Option to Purchase by the developer.
Within about 3 weeks: The developer delivers the Sale & Purchase Agreement. You have a defined period to sign it and pay the stamp duty.
Within 8 weeks of the OTP date: You typically pay up to 20% of the price (the booking fee counts toward this), and stamp duty falls due.
Over the build period: Further payments are drawn down on the Progressive Payment Scheme as construction reaches defined milestones, foundation, walls, roof, and so on.
Temporary Occupation Permit (TOP): When the project is ready for occupation, you collect keys. A further payment falls due at this stage.
Certificate of Statutory Completion: The final retention sum is paid, usually about a year after TOP.

From booking to TOP, a new launch commonly runs two to four years. That is not a delay, it is the model. The advantage is a gentler cash flow because your mortgage instalments are smaller in the early years when only part of the loan is drawn down.

Resale vs New Launch: Timeline Side by Side

Stage	Resale condo	New launch (BUC)
Commitment document	Option to Purchase	Developer OTP, then Sale & Purchase Agreement
Initial payment	1% option fee	Typically 5% booking fee
Exercise / signing window	14 to 21 days	S&P delivered within ~3 weeks
Stamp duty due	Within 14 days of exercising OTP	Within 14 days of signing S&P
Payment structure	5% deposit, balance at completion	Progressive Payment Scheme over build
Time to keys	~10 to 12 weeks	~2 to 4 years

Timelines indicative for 2026. Confirm specific windows in your OTP or S&P and with your conveyancing lawyer.

What Slows a Condo Purchase Down?

On a resale, the most common cause of delay or collapse is a bank valuation that comes in below the agreed price. The loan is sized on valuation, not on price, so a gap must be bridged with cash. If you do not have that cash, you either renegotiate or walk away, and your 1% option fee is at risk if you cannot complete.

Other delays I see:

CPF shortfalls. Buyers assume CPF will cover more than it does. Your lawyer needs the CPF withdrawal confirmed early.
Slow loan documentation. Banks need signed documents back promptly. A week lost here pushes completion.
Title issues. An outstanding caveat, an undischarged mortgage on the seller's side, or an estate matter can stall completion.

According to IRAS, stamp duty on a property purchase must be paid within 14 days of the document being signed if signed in Singapore. Missing that deadline triggers penalties, so build it into your cash plan from day one rather than treating it as an afterthought.

Winfred's Take

The mistake I see most often is treating the OTP as the start of the financing conversation. By the time you have paid your 1% and the 14 to 21 day clock is running, you should already know your loan amount, your valuation comfort, and your cash position. Buyers who get their Approval-in-Principle before they view rarely have a stressful transaction. Buyers who chase the loan after signing the OTP are the ones who lose sleep, and sometimes lose their option fee.

Frequently Asked Questions

Can the OTP window be extended?

It can, but only by agreement with the seller, usually documented as a written extension. Do not assume an extension. If you need more time for financing, raise it well before the deadline.

How quickly can a resale purchase complete if both sides want speed?

Completion is negotiable. Some transactions complete in around 8 weeks. The constraint is conveyancing, loan documentation and CPF processing, which need a minimum runway.

Do I need an estate agent to buy a condo?

No. There is no legal requirement to engage a licensed estate agent in Singapore; buyers and sellers may transact directly. Many buyers still appoint one for negotiation and process management, but it is a choice, not a rule.

When do I get keys for a new launch?

At Temporary Occupation Permit (TOP), which for a BUC is typically two to four years after booking. The developer notifies you and a payment falls due at that point.
