Buying a Condo in Singapore involves several important steps, from the time the buyer and seller agree on the price to the final handover of the property. For first-time buyers, the confusing part is often not choosing a property, but understanding what to do after signing the OTP, when payments are due, when to arrange financing, and when the transaction is considered complete.
In simple terms, the resale process for a Condo in Singapore can generally be summarised as:
Agreeing on the price → Seller issues the OTP → Option Period → Buyer decides whether to exercise the OTP → Stamp duty and loan arrangements → Lawyer handles the transfer of ownership → Completion → Property handover
This article focuses on the main steps from OTP to Completion, helping buyers build a clear timeline of the transaction.
OTP stands for Option to Purchase.
Once the buyer and seller have agreed on the price and other key terms, the seller will issue an OTP to the buyer. After paying the Option Fee, the buyer obtains the right to purchase the property in accordance with the OTP terms within the agreed period. Signing the OTP does not mean that the buyer has exercised the option; the buyer must still exercise it in accordance with the OTP within the Option Period.
The OTP will generally specify:
• The purchase price;
• The Option Fee;
• The Option Period;
• The method, deadline and requirements for exercising the OTP;
• Completion arrangements.
For buyers, signing the OTP marks an important stage in the transaction. Before signing, buyers should confirm the purchase price, borrowing capacity, cash and CPF arrangements, and other key transaction terms. It is best to assess loan eligibility and prepare funds early, as the time available after the OTP is issued is usually limited.
After signing the OTP, the buyer enters the Option Period. This is an important window for deciding whether to proceed with the purchase in accordance with the OTP terms.
During this period, the buyer will generally need to complete or confirm several key matters, including:
• Confirming the bank loan arrangements and loan terms;
• Confirming cash and CPF arrangements;
• Appointing a lawyer to handle the property transaction;
• Having the lawyer review the OTP and conduct the relevant title and legal checks;
• Confirming arrangements for paying stamp duties and other costs.
If the buyer decides to proceed, the buyer must exercise the OTP in the manner specified and within the deadline stated in it. After the OTP is exercised, the buyer and seller are generally required to proceed with the transaction in accordance with the contract. The buyer must also pay the Exercise Fee, if applicable, and fulfil the subsequent payment and transaction obligations.
If the buyer does not exercise the option within the specified period, the OTP will generally lapse and the buyer will lose the right to purchase the property under that OTP. The Option Fee is generally forfeited to the seller, but its treatment depends on the specific OTP terms. After signing the OTP, buyers should therefore confirm the Option Period expiry date, the method of exercise and any related payment requirements.
Exercising the OTP means that the buyer formally exercises the right to purchase the property.
Simply put:
Seller issues the OTP = The buyer obtains the option to purchase the property within the agreed period
Buyer exercises the OTP = The buyer exercises that option in accordance with the OTP terms
The buyer must exercise the OTP in the manner and within the period specified in it. This usually involves signing and delivering the exercise portion of the OTP and paying the agreed Exercise Fee, if applicable.Once the OTP has been validly exercised, both parties are generally required to proceed with the sale in accordance with the transaction documents. The buyer should not treat the transaction as an ordinary “reservation” that can be cancelled at will. If the buyer subsequently fails to complete the transaction, this may result in a breach of contract and related legal and financial consequences, depending on the contract terms and circumstances.
Buyers should therefore confirm their loan arrangements, funding and key transaction terms as far as possible before exercising the OTP. After exercising it, the buyer must still fulfil the agreed payment, stamp duty and other transaction obligations.
When purchasing a Condo in Singapore, buyers also need to account for property stamp duties.Two common types are:
BSD (Buyer’s Stamp Duty)
BSD is generally payable when purchasing property in Singapore. It is usually calculated on the higher of the purchase price or market value and is charged at the applicable progressive rates.
ABSD (Additional Buyer’s Stamp Duty)
Whether ABSD is payable and the applicable rate depend on factors such as the buyer’s profile and the number of residential properties already owned. The applicable rate is generally determined by the buyer’s status and circumstances at the time of purchase.
BSD and ABSD are generally payable within 14 days after the relevant purchase document is signed in Singapore. If the document is signed overseas, they are generally payable within 30 days after it is received in Singapore. Buyers should include stamp duties in their overall purchase budget, rather than calculating only the property price and down payment. The lawyer should confirm the amounts, applicable rates and payment deadlines based on the buyer’s circumstances and transaction documents.
After the OTP has been exercised, the lawyer will continue handling the legal process for the property transaction, commonly known as conveyancing.
In simple terms, the lawyer handles the legal and title-related procedures required for the transaction, helping the parties complete the sale in accordance with the transaction documents and arranging for the transfer of ownership.
The main work includes:
• Reviewing the property title and relevant registration information;
• Reviewing and preparing the legal documents required for the transaction;
• Communicating with the seller’s lawyer;
• Coordinating with the bank and lending institution, where applicable;
• Preparing the legal documents required for Completion;
• Checking the transaction terms, source of funds and payment arrangements.
At this stage, the buyer mainly needs to provide the lawyer with the required information, sign documents and make the necessary funding and loan arrangements.
For buyers, the process can be understood simply as follows:
The OTP and its exercise establish whether the buyer is proceeding with the purchase under the agreed terms; conveyancing deals with the legal procedures and prepares for payment, transfer of ownership and handover at Completion.
The funds for a Condo transaction generally come from three main sources:
Cash + CPF + Bank Loan
The conditions, uses and payment timing for each source may differ. Buyers should plan their funding throughout the transaction in accordance with the OTP, loan documents and the lawyer’s payment instructions, rather than preparing only a single “down payment”.
Cash
The buyer will generally need to prepare part of the down payment, as well as stamp duties, legal fees and other related costs. The Option Fee and any amount payable when exercising the OTP must also be paid in the manner specified in the OTP. Some payments may be due before Completion; the amounts and timing depend on the transaction documents and the lawyer’s instructions.
CPF
Subject to CPF requirements, buyers may apply to use their CPF Ordinary Account (OA) savings to pay part of the purchase price, stamp duties, legal fees and related costs, or to service a housing loan. The amount that can be used is subject to CPF rules and conditions, including the property’s valuation and remaining lease. CPF funds must be applied for through the lawyer and are not automatically available.[3]
Bank Loan
If the buyer is purchasing the Condo with a bank loan, the buyer should complete the loan application, valuation and loan documents in good time and satisfy the bank’s disbursement conditions. The bank will disburse the loan in accordance with the loan documents and transaction arrangements, usually with the lawyer coordinating the funds for payment of the purchase price balance at Completion.
Buyers should plan for payments at each stage, including OTP-related payments, stamp duties, legal fees, the Completion balance and other costs. They should also set aside funds in case the valuation is lower than the purchase price or the available loan or CPF amount is insufficient.
Completion is an important stage at which the buyer and seller complete the payments, transfer of ownership and other transaction procedures in accordance with the transaction documents.
Completion will generally involve:
• The buyer paying the remaining purchase price using cash, approved CPF funds and the bank loan;
• The buyer’s and seller’s lawyers completing the transfer of funds and documents;
• Repayment of the seller’s outstanding housing loan, if applicable, and completion of the related procedures;
• Registration of the transfer of ownership;
• Handover of the property and keys as provided for in the transaction documents.
The Completion Date is specified in the transaction documents. The bank loan and CPF funds usually need to be available before or on Completion, as arranged by the lawyers. The buyer should ensure that all funds and documents requested by the lawyer are ready.
Before Completion, the buyer should confirm that:
• The loan has been approved, the relevant documents have been signed, and the bank’s disbursement conditions have been met;
• The CPF application and funding arrangements have been handled as required;
• The required cash is available and will be paid in accordance with the lawyer’s instructions;
• BSD, any applicable ABSD and other costs have been paid by the relevant deadlines;
• All documents requested by the lawyer have been signed or submitted.
Completion is not simply a matter of signing documents; it is the legal stage at which the transaction’s payments, transfer of ownership and other completion procedures are carried out in accordance with the agreement. However, the transfer of ownership and physical handover do not always take place at the same time. The handover date and whether the property must be vacant depend on the transaction documents.
After Completion, the buyer will generally take possession of the property and receive the keys in accordance with the transaction documents. If vacant possession is agreed, the keys and access devices are usually handed over around Completion. If the property is sold subject to an existing tenancy, the buyer must take over the property in accordance with the tenancy and transaction documents and may not be able to move in immediately after Completion.
The handover will generally involve:
• Collecting the property keys, access cards and related devices;
• Liaising with the Condo’s MCST or Managing Agent;
• Checking the condition of the property and any items agreed to remain;
• Arranging water and electricity accounts as required;
• Confirming the existing tenancy, rent, deposit and tenant handover arrangements, if applicable.
If the property is to be delivered vacant under the agreement, the buyer can arrange renovation, own occupation or rental according to their plans. If it is sold subject to an existing tenancy, the buyer should confirm the tenancy period, rent, deposit, obligations under the tenancy and handover arrangements, and take over the property as agreed.
Completion is an important transaction milestone, but the handover arrangements and subsequent management matters should still be checked against the transaction documents and the property’s actual condition.

First-time Condo buyers do not need to memorise every technical term, but they should understand these key dates:
① OTP Date
When is the OTP signed, and when does the Option Period begin?
② Option Period
How long does the buyer have to decide whether to proceed in accordance with the OTP terms?
③ Exercise Deadline
What is the latest date by which the buyer must exercise the OTP in the required manner?
④ Stamp Duty Deadline
When are BSD and any applicable ABSD due? The payment deadline generally runs from the date the relevant purchase document is signed. If the document is signed overseas, the deadline generally runs from the date it is received in Singapore. The lawyer should confirm the applicable document and deadline.
⑤ Completion Date
When must final payment and the transfer of ownership be completed? Whether the property handover or key collection takes place on the same date also depends on the transaction documents.These dates run throughout the transaction. Missing a deadline or failing to prepare funds in time may result in a breach, additional costs or disruption to subsequent arrangements.
Buying or selling a Condo in Singapore does not end with signing the OTP; the transaction moves into the execution stage from that point onwards.
The process can be summarised as:
Seller issues the OTP → Option Period → Exercise OTP → Stamp duty and funding arrangements → Conveyancing → Completion → Handover as agreed
For buyers, the main priorities are to confirm loan arrangements, prepare funds for each stage and keep track of the key dates. Understanding when each stage takes place, what needs to be done and when payments are due can make the transaction clearer and help reduce problems caused by inadequate funding or timing arrangements.
