Booking a new launch condo in Singapore runs in five stages: registering interest (the expression of interest, or EOI), the ballot that sets the queue order, unit selection on booking day, payment of the booking fee against an Option to Purchase (OTP), and the exercise of that option within a fixed window. Only the fourth stage creates a financial commitment, and the figures a buyer needs for it (financing, stamp duty, cash and CPF) are best settled before the first. haio publishes transaction data and an affordability check for exactly that preparation.
TL;DR
- Submitting an EOI registers interest in the allocation process. It is not a purchase, and it is not a binding reservation.
- The ballot decides the order in which buyers are called, and a queue number is a turn, not a unit.
- The booking fee is paid when an OTP is granted. The option lasts 3 weeks from delivery of the documents, and 20% of the price (less the booking fee) is due on exercise or within 8 weeks of the option date.
- If the option is not exercised, the developer refunds 75% of the booking fee within 4 weeks after expiry.
- Financing, cash and CPF should be worked out before booking day, because the decision is made at the showflat within minutes.

The booking process at a glance
The sequence is the same for most private launches, although each developer sets its own dates, forms and showflat rules.
| Stage | What happens | Commitment |
|---|---|---|
| 1. Preparation | Budget, loan eligibility, shortlist of projects and unit types | None |
| 2. EOI | Interest is registered with the developer or its appointed sales team | None, if no option has been granted |
| 3. Ballot | Where demand exceeds supply, queue order is assigned | None |
| 4. Unit selection | The buyer is called in queue order and chooses from units still available | Not yet binding |
| 5. Booking fee and OTP | The booking fee is paid and the developer grants an option | Booking fee at stake |
| 6. Exercise | Sale and Purchase Agreement (S&P) signed and the next payment made | Binding purchase |
The sections below take each stage in turn, with what it requires and where buyers most often lose ground.
Stage 1: preparing before any registration
The booking itself is quick, and the preparation is where the process is won or lost. A buyer who arrives on booking day without a settled budget has to decide on price, floor and stack under time pressure.
Four items are worth fixing first:
- A realistic price ceiling. This depends on income, existing debts, the loan the bank is prepared to grant, cash available and CPF Ordinary Account savings. haio's Affordability check is built for this step, and haio also publishes the latest mortgage rates so that the monthly instalment can be tested at the rate a lender is quoting.
- A shortlist of projects and unit types. Comparing a project's launch pricing with recent transactions nearby shows whether an asking price is in line with the market. The Transactions data on haio lists past transactions by project, and individual project pages such as Suites at Bukit Timah or Affinity at Serangoon show price history. For a view of how developers arrive at launch prices, haio's note on condo pricing strategy in Singapore is a useful companion.
- A financing position. Many buyers obtain an in-principle approval from a bank before committing, so that the loan quantum is known rather than assumed.
- A cash plan. The booking fee, stamp duties, legal and financing costs, and a reserve after completion all draw on cash and CPF. The progressive payments after the S&P follow a schedule set by regulation, so the cash-flow plan should extend well past booking day.
A second-stage check for households that own a property is how much the current home is worth and when it will be sold. A launch purchase that depends on a sale not yet completed is one of the commonest reasons buyers fail to proceed when their number is called. Homeowners can obtain a data-based estimate through haio's valuation tools.
Stage 2: the expression of interest (EOI)
The EOI is the registration step. It tells the developer which buyers want to take part in the allocation and, usually, which unit types they are considering.
The question most first-time buyers ask is whether it commits them. It does not. The disclaimer on the Thomson Reserve project website is representative: it states that submitting an enquiry or registering interest is not a binding reservation, an option to purchase or any contractual commitment, and that any purchase is governed solely by the Option to Purchase and the Sale and Purchase Agreement signed with the developer. Project terms differ, so the terms printed on each project's own form and website are the ones that apply.
Practical points at this stage:
- Forms and identification. Developers ask for identity details, and for a joint purchase the details of every buyer. Names on the EOI should match the names intended for the OTP.
- Unit type preferences. Where the form asks for unit types, listing only those that fit the budget keeps the shortlist honest.
- Registration window. Windows are set by each developer and can be short. The developer's website or showflat gives the current dates, which is why this article does not quote any.
A buyer who registers and then decides against buying loses nothing financially as long as no option has been granted, which is the stage at which money is first paid.
Stage 3: balloting and the queue number
When more buyers register than there are units released, the developer runs a ballot. The result sets the order in which buyers are invited to choose a unit. Where demand is lower, buyers may simply be admitted in order of registration or by appointment, so a ballot is not universal.
Two details cause confusion:
- A registration or ballot reference is not necessarily a queue position. The reference identifies an entry, and the ballot result sets the selection order. The message or ticket received after the EOI should be read for which of the two it is.
- The queue number is a turn, not a unit. A buyer called early chooses from more units, but nothing obliges that buyer to book one. Buyers called later often still find a suitable unit, because some buyers ahead of them do not proceed. A step-by-step account of the allocation mechanics is in haio's guide to the new launch balloting process.
It follows that a good queue number does not substitute for preparation. A buyer with loan approval, a budget and a shortlist at a middling number is in a stronger position than one with an early number and none of the three, since the latter may hesitate when called or be unable to proceed.
Stage 4: booking day and unit selection
On booking day, buyers are called in queue order, normally in small groups, and shown the units still available, usually on a sales board or screen in the showflat. When a unit is chosen, it is removed from the available list, so a delay in deciding can mean the preferred unit goes to the next buyer.
The decision is easier when each of these has been settled in advance:
- A ranked list of units. A first choice and two or three fallbacks by stack, floor and facing, each with a maximum price.
- A reference price per square foot. Comparing the quoted price per square foot with nearby launches and resale transactions shows whether a premium for a high floor or a view is in line with the market. Haio's data tools are designed for this comparison.
- A decision to walk away. If nothing on the shortlist is available at a price within budget, leaving without booking is a legitimate outcome, and no cost is incurred.
- Everyone present who must sign. Joint buyers who disagree at the counter lose time that the queue does not give back.
The unit is chosen from a sales gallery and a model flat, so the buyer commits to a home that does not yet exist. The floor plan, the orientation and the surroundings therefore deserve more attention than the showflat finishes. Haio's property viewing checklist covers what to look at when visiting, and a pre-settlement inspection checklist is useful again at completion, when the finished unit is inspected for defects.
Stage 5: the booking fee and the Option to Purchase
Once a unit is chosen, the buyer pays the booking fee and the developer grants an Option to Purchase. In a new launch of uncompleted private housing, the form of the option is prescribed by the Housing Developers Rules, so its main terms are the same across developers.
According to the Housing Developers Rules on Singapore Statutes Online, the booking fee is the consideration for the developer granting the option at the stated purchase price. It may be paid by cheque or cashier's order crossed "Account Payee only", or by telegraphic transfer to the vendor's project account. The payment method accepted on the day is confirmed by the sales team, so it is worth arranging in advance rather than at the counter.
The OTP is the first document with legal force. It fixes the unit, the price and the period during which the buyer alone may decide to proceed. haio's explainer on how an OTP works in Singapore sets out the clauses in more detail.
Stage 6: exercising the option and the deadlines that follow
The same rules set the time limits, and they are strict:
| Item | Rule under the Housing Developers Rules |
|---|---|
| Option validity | Expires 3 weeks after the prescribed documents are delivered to the purchaser or the purchaser's solicitor |
| Exercising the option | Sign and return the S&P execution copies before the option expires |
| Payment on exercise | 20% of the purchase price, less the booking fee, on exercise or within 8 weeks after the option date |
| If not exercised | The vendor refunds 75% of the booking fee within 4 weeks after expiry |
| Early expiry | The option ends earlier if the purchaser gives written notice of not wishing to exercise |

A worked example
Take a unit with a purchase price of S$1,500,000 and a booking fee of S$75,000 (the booking fee is set in the option and varies by project, so S$75,000 here is an illustration). If the buyer exercises the option, the payment due on exercise is 20% of S$1,500,000, which is S$300,000, less the S$75,000 already paid: S$225,000. If the buyer lets the option lapse, the refund is 75% of the booking fee, S$56,250, and the remaining S$18,750 is forfeited.
The example shows why the 3-week window is used for the work that should already be done: reading the S&P with a lawyer, confirming the loan, and arranging cash and CPF for the payment. The progressive payments that follow are tied to construction stages, and they are covered in a separate schedule, so they are not repeated here.
Common reasons bookings fail
The pattern is consistent across launches. Buyers called in the queue often cannot proceed for reasons that were knowable beforehand:
- Loan approval has not come through.
- The existing home has not been sold, or the timing of its sale is unclear.
- The stamp duty position, including any additional duty that applies to the buyer's circumstances, has not been confirmed.
- A cheque or transfer has not been arranged.
- The joint buyers have not agreed on the unit.
Each item can be settled in the weeks before booking day, which is why the process rewards preparation more than speed. Buyers who treat a strong queue number as a reason to commit also take a risk: the number gives first choice of units, and it says nothing on whether a specific unit is worth its price.
What has changed recently
Rules for new launch sales can be updated by the authorities, and developers revise their own procedures between projects, including the use of electronic registration. Because the cooling measures, stamp duty rates and lending limits that frame a purchase can move, the figures in force at the time of booking come from the relevant government agencies and the developer's own sales documents. The statutory option terms in this article are those of the Housing Developers Rules cited above.
Our perspective
The booking process is short, and most of the risk sits before it. A buyer who walks into a showflat with a verified budget, a ranked list of units and a price reference has made the important decisions already.
At haio, we built the platform around that preparation. The Affordability check turns income, debts and funds into a price range, the mortgage rate information shows what a loan costs at current market rates, and the transaction data shows what comparable homes have actually sold for. Together, these let a buyer judge a launch price against evidence, not against the momentum of the day.
The same applies to agents who want to show clients neutral figures, and to homeowners who need to know what their current home is worth before committing to a new one. We combine Singapore's residential data sources so the comparison is made in one place.

FAQ
Does submitting an EOI commit me to buying?
No. An EOI registers interest in the allocation process, and the developer's own disclaimer typically states that it is not a binding reservation or an option to purchase. The first commitment arises when the booking fee is paid and an OTP is granted, so each project's terms should be read before registering.
Is a good queue number a reason to book?
No. The queue number sets when a buyer is called, and it gives a wider choice of units. Whether a unit suits the budget and the household is a separate question, and walking away without booking is a valid outcome.
How long do I have after receiving the OTP?
Under the Housing Developers Rules, the option expires 3 weeks after the prescribed documents are delivered to the purchaser or the purchaser's solicitor. The S&P execution copies must be signed and returned within that period, and 20% of the price less the booking fee is paid on exercise or within 8 weeks after the option date.
What happens to the booking fee if I do not proceed?
If the option is not exercised, the vendor refunds 75% of the booking fee within 4 weeks after the option expires. The remaining 25% is not refunded, so the decision to proceed is best taken with financing already confirmed.
What should I prepare before booking day?
A price ceiling based on income, loan, cash and CPF; a ranked list of units; an in-principle loan approval; and the booking fee in a payment form the developer accepts. Haio's Affordability check covers the first of these.
