Can a foreign buyer exercise an OTP from overseas?

Yes, though it needs planning. The document can be executed abroad, in which case the stamp duty window becomes 30 days counted from the day the document reaches Singapore rather than 14 days from exercise, and a conveyancer can act on a power of attorney. The two things that catch overseas buyers are the funds arriving late and the verification checks taking longer than a local file. Both are solved by starting before the option period does, not during it.

What is the difference between an OTP and a Sale and Purchase Agreement?

On a private resale the exercised Option to Purchase is the contract, and there is normally no separate agreement. On a new launch from a developer, the OTP is followed by a Sale and Purchase Agreement issued by the developer, which carries the progressive payment schedule and the completion obligations. The stamp duty clock keys off whichever comes first.

Option to Purchase Singapore: The Buying Timeline

Q: What is an Option to Purchase in Singapore?

The Option to Purchase is a document the seller grants the buyer that holds the property for a fixed window in exchange for an option fee. It is not yet a sale. During the option period the buyer can walk away and lose only the option fee, or exercise the option and become contractually committed. That structure, a paid pause before commitment, is the defining feature of the Singapore private resale process.

Q: How much is the option fee on a Singapore resale?

Market convention on a private resale is 1% of the purchase price as the option fee, with a further 4% on exercise, making 5% before completion. These are conventions negotiated between the parties rather than rates fixed by law, and the figures belong in the document itself. A new launch works differently: booking usually takes a 5% to 10% deposit against an OTP with a 14 to 21 day exercise window.

Q: What happens if I do not exercise the Option to Purchase?

The option lapses and the seller keeps the option fee. On the 1% convention that is S$20,000 forfeited on a S$2,000,000 home, which is the price of the pause. Nothing further is owed and no stamp duty arises, because there is no completed acquisition to stamp. This is the cheapest exit point in the entire Singapore purchase process and it closes the moment you exercise.

Q: How long does a Singapore resale purchase take?

Count roughly 10 to 12 weeks from signing the Option to Purchase to completion on a typical private resale, with the option period taking the first two weeks and legal completion the rest. A new launch runs on a completely different clock, because payments follow the construction stages under a progressive payment schedule that can span several years to Temporary Occupation Permit.

Quick answer: the Option to Purchase buys you a paid pause, not a sale. The seller holds the property for a fixed window; you pay an option fee, conventionally 1% of price on a private resale, and you can still walk away losing only that. Exercise it and you are committed, and stamp duty falls due within 14 days. See cost of buying property in Singapore for the full acquisition stack.

What the OTP actually is

A seller grants the buyer an option. For a fee, the property is held off the market for a stated window. During that window the buyer decides.

The structure is deliberately asymmetric. The seller is bound and cannot sell elsewhere; the buyer is not bound and can walk. What the buyer pays for that asymmetry is the option fee, which the seller keeps if the option lapses.

This is why the OTP is not “an offer” in the loose sense. It is a priced instrument with a deadline, and understanding it as a purchased decision window rather than as paperwork changes how you use it.

The money, stage by stage, on a private resale

Stage	Convention	What it commits you to
Option fee, on grant of the OTP	1% of purchase price	Nothing; you may still walk
Exercise fee, on exercising	A further 4%, making 5%	Full contractual commitment
Stamp duty	Within 14 days of exercising	BSD plus any ABSD, on the higher of price or value
Completion	Balance, typically 8 to 10 weeks later	Keys and title

Those percentages are market convention, negotiated between the parties in the document itself. No statute fixes them, and a seller in a soft market will sometimes take less while a seller with competing buyers will ask for more.

On a S$2,000,000 resale, the convention translates as follows.

Line	Amount
Option fee at 1%	S$20,000
Exercise fee at 4%	S$80,000
Subtotal before completion	S$100,000
Stamp duty, foreign buyer without relief, at 60% ABSD plus BSD	Over S$1,200,000
Balance at completion	The remainder of the price

The last two rows are the reason the 14-day clock deserves more respect than the option fee does. Losing S$20,000 by not exercising is survivable. Missing a stamp duty deadline on S$1,200,000 is not, and the ABSD guide sets out how that liability behaves.

The 14-day clock

Buyer’s stamp duty and any ABSD are payable within 14 days of the date of purchase. IRAS defines that date as the exercise of the Option to Purchase, or the date of the Sale and Purchase Agreement where no OTP is granted, or the date of transfer where neither exists. Granting the OTP is not the trigger. Where the document is executed outside Singapore the window is 30 days, counted from the day it is received in Singapore rather than from the day it was signed.

For a buyer in Singapore with local funds, 14 days is comfortable. For a buyer moving money from another jurisdiction it is not, and the sequence that fails looks like this: exercise the option, then start the transfer, then discover the correspondent banking takes a week, then discover the receiving bank wants source-of-funds documents. The deadline does not move for any of that.

The fix is ordering. Start the transfer before you exercise, not after. A foreign buyer should treat the option period as the funding period, which is what it is for.

Resale against new launch: two different clocks

	Private resale	New launch from developer
What you sign	Option to Purchase, exercised	OTP, then a Sale and Purchase Agreement
Upfront	1% then 4%, by convention	5% to 10% booking deposit
Exercise window	Negotiated, commonly around 14 days	Commonly 14 to 21 days
Payment pattern	Balance at completion	Progressive, tied to construction stages
Time to keys	Roughly 10 to 12 weeks	Years, to Temporary Occupation Permit

A buyer comparing the two on price alone misses that they are different financial products. A resale asks for the whole amount inside three months. A new launch spreads payments across construction, which changes both the cash profile and the risk, and the off-plan versus resale guide works through that trade.

The full resale timeline

Week	What happens
Week 0	Offer agreed; OTP granted against the option fee
Weeks 0 to 2	Option period: financing confirmed, conveyancer appointed, funds moved
Week 2	Exercise, or let it lapse and lose the option fee
Weeks 2 to 4	Stamp duty paid inside the 14 day window
Weeks 2 to 10	Legal completion: title searches, requisitions, mortgage documentation
Weeks 10 to 12	Completion, keys, and registration

The single most compressed part is the option period, and it is compressed for everyone at once: the bank, the conveyancer and the buyer’s own bank abroad are all working inside the same two weeks. Anything that can be done before the OTP is granted should be.

What to do before you take the OTP

Task	Why it belongs before, not after
Confirm what you can borrow	The option fee is at risk if financing fails
Appoint a conveyancer	Waiting until exercise loses days from a 14 day window
Start moving funds	Correspondent banking and verification take time
Confirm which ABSD rate applies	Profile on the stamp date decides it, not on booking day
Assemble source-of-funds evidence	The most common cause of a stalled overseas transfer

The conveyancing guide covers what the lawyer actually does across those weeks, and the foreign buyer guide covers eligibility before any of this starts.

Where the option period actually goes wrong

Three failures account for most lost option fees, and none of them is about the property.

Financing that was indicative rather than approved. An in-principle approval is not a loan. A buyer who takes the OTP on an indicative number and then finds the bank valuing the property below the agreed price has a shortfall to fund in cash inside two weeks, or a lapsed option. Confirm what the bank will actually lend against this specific unit, not against a price band.

A profile change between booking and stamping. ABSD is assessed on the buyer’s profile as it stands on the stamp date. A buyer who completes on another property in the interim, or whose PR is granted or lapses, can find a different rate applies from the one they budgeted. On a S$2,000,000 purchase the difference between 5% and 60% is S$1,100,000, which is not a rounding adjustment.

Money that moved too late. Correspondent banking, holiday calendars in the sending country and source-of-funds verification each add days. Two weeks disappears quickly when three institutions each take three days.

What the option fee actually buys

It is worth pricing the pause honestly, because buyers often treat the option fee as a deposit rather than as the cost of a decision.

Scenario	What you spend	What you get
Take the OTP, exercise	1% then 4%, then the balance	The property
Take the OTP, let it lapse	1%, forfeited	Two weeks of exclusivity and the information gathered in them
Never take the OTP	Nothing	No hold on the property; a competing buyer can take it

On a S$2,000,000 home the middle row costs S$20,000. That is expensive for a change of heart and cheap for a discovery: a valuation that comes in low, a lease decay problem, a body corporate issue, or a financing answer that arrives late. The option period is the only stage of a Singapore purchase where new information can still change the outcome cheaply, and buyers who use it for verification rather than for celebration get better results.

HDB resale runs on its own process

Everything above describes private property. An HDB resale follows a separate process administered by the board, with its own option arrangements, eligibility checks and a resale portal timeline that does not map onto the private sequence.

The practical point for a reader here is not to transfer assumptions between the two. A household moving from an HDB flat into private stock is running both processes at once, on different clocks, and the sequencing of the sale against the purchase is what decides the ABSD position. That interaction is covered in the HDB upgrader guide.

The one thing worth remembering

The Option to Purchase is the last cheap exit. Before exercise, walking away costs the option fee and nothing else. After exercise, you own a stamp duty liability that is due in two weeks and a contract that completes. Everything a careful buyer wants to verify, financing, title, the ABSD rate that will apply, belongs on the near side of that line.

Frequently Asked Questions

What is an Option to Purchase in Singapore?

A document the seller grants holding the property for a fixed window in exchange for an option fee. It is not yet a sale: during the window the buyer can walk away losing only the fee, or exercise and become contractually committed.

How much is the option fee on a Singapore resale?

Convention on a private resale is 1% of price as the option fee and a further 4% on exercise, 5% in total before completion. These are negotiated conventions, not statutory rates. A new launch instead takes a 5% to 10% booking deposit with a 14 to 21 day exercise window.

What happens if I do not exercise the Option to Purchase?

The option lapses and the seller keeps the option fee, which on the 1% convention is S$20,000 on a S$2,000,000 home. Nothing further is owed and no stamp duty arises. It is the cheapest exit in the process, and it closes the moment you exercise.

When is stamp duty due after the OTP?

Within 14 days of the date of purchase, which IRAS defines as the exercise of the Option to Purchase, or the Sale and Purchase Agreement where no OTP is granted. Granting the option does not start the clock. A document executed outside Singapore gets 30 days, counted from its receipt in Singapore.

How long does a Singapore resale purchase take?

Roughly 10 to 12 weeks from OTP to completion, with the option period taking the first two weeks. A new launch runs on a progressive payment schedule tied to construction and can span years to Temporary Occupation Permit.

The 14 day stamp duty window, and the 30 day window for documents executed outside Singapore, follow IRAS stamping requirements as recorded in this site’s fact base. Option and exercise fee percentages are market convention on private resale rather than statutory rates, and are negotiated in the document itself. Confirm your own timeline and deadlines with your conveyancer, because the dates in your Option to Purchase govern, not the conventions described here.
