The balloting process for a new launch condominium in Singapore is a developer-run draw that decides the order in which registered buyers choose a unit. Buyers submit an Expression of Interest (EOI) with identity documents and a cheque during the preview period, receive a ballot number, and are called into the booking room in the sequence the draw produces. Balloting is used when interest in a project exceeds the number of units released on launch day. It sets the queue order and does not reserve any particular unit.
This guide sets out each stage in sequence, the payments that follow a successful booking, the differences between private condominium and Executive Condominium (EC) procedures, and a preparation checklist for first-time buyers.
TL;DR
- Balloting decides the queue order for unit selection when demand exceeds the units on offer, and the draw is random.
- Registration usually involves an EOI, a copy of the NRIC (or other identification) and a cheque, which is typically not banked unless a unit is booked.
- A ballot number sets when a buyer is called, not which units remain, so a shortlist with backup units is needed.
- A buyer who is late, absent, missing documents or found ineligible can be skipped, according to developer eligibility booklets.
- The booking fee is 5% of the price in cash, and a further payment follows when the Sale and Purchase Agreement is signed.

What balloting is and when it is used
A new launch condominium is sold by a developer directly, unit by unit, rather than through a resale negotiation. When a project is popular, several buyers may want the same stack or the same layout, and a first-come-first-served queue would favour whoever arrived earliest. Balloting replaces that with a random draw: each registered buyer receives a number, and the numbers determine the order of selection.
Not every launch is balloted. Smaller or slower-moving projects may sell on a simple queue or by appointment, and a developer may switch to a first-come-first-served method once the balloted queue has been cleared. One developer's eligibility booklet for an EC launch states exactly that: after the balloted queue is exhausted, booking may become first-come-first-served. The specific rules of each project are set out in the developer's own sales documents, which should be read before registering.
The process from preview to booking day
The sequence below is the usual pattern for a balloted private condominium launch. The details (cut-off times, forms, venue) differ by developer and project.
- Preview period. Showflats open to the public (and often to invited buyers first). Pricing is released through a price list, commonly a few days before launch.
- Registration of interest. The buyer submits an EOI form to the developer or its marketing agent. The form records the unit types, price range or specific units of interest, and the buyer's identity details.
- Cheque submission. An EOI is typically accompanied by a cheque, often post-dated or left blank in amount, made out to the developer's project account. Developer marketing material for recent launches describes this as a blank cheque submitted with the EOI, with no payment deducted until a unit is booked. Submission does not oblige the buyer to purchase.
- Ballot number allocation. The developer runs the draw, in many recent launches electronically, and each registered buyer receives a number.
- Booking day. Numbers are called in sequence. When a buyer's number is called, the buyer enters the booking room with the required documents and chooses from the units still available.
- Option to Purchase. On selecting a unit, the buyer pays the booking fee and receives the Option to Purchase (OTP).
How ballot numbers translate into order and timing
The ballot number is a queue position. A low number is called earlier, which gives a wider choice of units, while a high number is called later, after popular layouts and floors may have been taken. Each buyer is allotted a limited time at the selection desk. Marketing-side guides commonly cite roughly 10 to 20 minutes, which makes a prepared shortlist more useful than browsing the unit chart in the booking room.
The draw does not guarantee that every registered buyer will be able to book. If the number of interested buyers is large, those with later numbers may find their shortlisted units sold. Buyers with a late number can still choose a different stack, floor or unit type from what remains, which is why a ranked list is more practical than a single target.
What the booking room looks like
The booking room is the point at which the numbers called become decisions. A sales representative displays the live availability chart, the buyer confirms a unit, and the developer's staff verify identity and eligibility documents. Where a buyer has a bank-loan approval in principle, an HDB Flat Eligibility letter (for EC purchases) or other required document, it is presented at this stage. A buyer who arrives without the required documents risks losing the turn.
What happens if a buyer misses a turn or does not book
Balloting rules are enforced strictly because every skipped slot delays the buyers behind. Developer eligibility booklets set out the consequences. In one such booklet, the examples given are a buyer who is late, absent, lacks documents or is found ineligible: the developer may reject the application or move to the next applicant in the queue.
In practical terms:
- Arriving after the number was called. The developer may pass over the number. Whether a buyer can re-join later in the queue depends on the project's rules.
- Choosing not to book. A buyer whose preferred units are gone is generally free to decline, since the EOI did not create an obligation to buy. Declining ends the buyer's participation in that round.
- Failing the eligibility check. For an EC, this includes the income ceiling and household composition checks. The EC eligibility rules for Singapore should be confirmed before registration.
Where a cheque was submitted and no unit was booked, the buyer should obtain written confirmation from the developer or agent of how and when the cheque will be returned or voided.
Payments and deadlines after booking
The cheque handed in at registration is not the booking payment. The payment is made when a unit is chosen. Under the standard schedule for private new launches, 5% of the price is payable in cash on exercising the Option to Purchase, and a further 15% falls due when the Sale and Purchase Agreement is signed, typically within about eight weeks. The remainder is paid progressively as construction stages are completed.
Stamp duties follow the same early timeline. Buyer's Stamp Duty and, where applicable, Additional Buyer's Stamp Duty (ABSD) are generally payable within a short window after the OTP is granted, and the buyer's lawyer normally manages the stamping. The Inland Revenue Authority of Singapore (IRAS) publishes the ABSD rates. For purchases on or after 27 April 2023, Singapore citizens buying a first residential property pay no ABSD, while a second property attracts 20%. Rates for permanent residents and foreigners differ, and the IRAS page carries the current figures.
A summary of the cash sequence for a private condominium:
| Stage | Typical payment | Usual funding |
|---|---|---|
| Registration (EOI and cheque) | No deduction until booking | Cheque held by developer |
| Option to Purchase (booking) | 5% of price | Cash |
| Sale and Purchase Agreement (about 8 weeks) | 15% of price | Cash and/or CPF Ordinary Account |
| Construction milestones | Progressive instalments | Bank loan, CPF |
| Stamp duties | Due soon after OTP | Cash or CPF, per rules |
Because 20% of the price is committed within about two months, and stamp duties come on top of that, the amount of cash available on booking day is a practical limit on which units are worth shortlisting.
Private condominium, EC and HDB balloting compared
The term balloting covers three distinct processes in Singapore, and they should not be confused.
| Aspect | Private condo new launch | EC new launch | HDB BTO or SBF |
|---|---|---|---|
| Who runs it | Developer | Developer | HDB |
| Eligibility check | Mainly financial and legal (ABSD, loan) | Household, income and HDB eligibility | Set by HDB |
| Ballot method | Developer-designed, often electronic | Electronic ballot with ballot ticket | Computerised HDB ballot |
| Outcome | Queue order for unit selection | Queue order for unit selection | Queue position for flat selection |
For ECs, one developer's booklet describes an electronic ballot held one day before the first day of public booking, with the queue number drawn at random and displayed on screen. The same document describes applicants scanning a ballot ticket into the electronic balloting system and depositing it in a ballot box. Procedures like these vary by project, so the booklet for the specific EC should be consulted.
The choice between an EC and a private condominium also affects the rules that follow after purchase. The Minimum Occupation Period (MOP), the eligibility conditions and the resale pathway are covered in the comparison of ECs and condominiums.
Preparing before balloting day
The pre-launch period is where most of the decisions are made. A buyer with a sound budget and a ranked shortlist is able to act within the few minutes available in the booking room.
Set the budget before looking at the price list
A buyer's ceiling is determined by the Total Debt Servicing Ratio (TDSR), the downpayment (including the cash portion that CPF cannot cover), and stamp duties. Calculating this in advance avoids selecting a unit that the bank later declines to finance at the required loan quantum. The haio affordability check gives a personalised estimate against a target budget, and a bank in-principle approval confirms it.
Buyers who still own a property should also review the sequence of purchase and sale, since it affects ABSD and cash flow. The rules and costs are covered in the guide to buying first and selling later in Singapore.
Build a ranked shortlist with backups
A workable shortlist contains units at three levels:
- Preferred units (the ideal stack, floor and facing).
- Acceptable alternatives in the same unit type at a similar price per square foot (psf).
- Fallback units that still meet the budget and the intended holding period, whether for owner-occupation or rental.
Popular layouts can sell quickly, and guides on new launch buying recommend preparing backup units for that reason.
Check the price against the surrounding market
Launch prices are set by the developer and are best judged against recent transactions in the area. Nearby condominiums with comparable age and tenure provide a benchmark. The Singapore property market data for H1 2026 gives wider context, and project pages such as Affinity at Serangoon or Seletar Park Residence show how price history and transactions are presented for individual developments.
Documents to bring
- NRIC, or passport and employment pass for foreigners
- The cheque or cheques specified by the developer
- Proof of address and, for joint buyers, details of each party
- Bank loan in-principle approval, if obtained
- For ECs, the HDB Flat Eligibility letter and any other eligibility papers named in the booklet
The developer's checklist for the specific project takes precedence over this general list.
Perspective
Balloting is often described as a matter of luck, but the outcome depends largely on what the buyer has settled beforehand. A ballot number fixes a position in the queue. The buyer's budget, shortlist and understanding of the payment schedule determine whether that position can be converted into a purchase.
At haio, we combine Singapore residential property data sources so that a buyer can compare a launch price with recent transactions, test the budget with a personalised affordability check, and review the mortgage rate environment before the preview period ends. Our view is that transparent pricing information is most valuable before a cheque is submitted, when the buyer still has the full range of choices.
For buyers who want deeper analysis, haio+ adds premium analytics and valuation reports to the free tools.

FAQ
Is the cheque submitted with the EOI cashed?
Developer material for recent launches describes the cheque as one that is not deducted until a unit is booked. Practice depends on the project, so the developer's terms should be read and any return of an unused cheque confirmed in writing.
Does a good ballot number guarantee a unit?
No. A low number is called earlier and has more units to choose from, but the buyer must still select a unit that fits the budget and be eligible when called. A late or absent buyer, or one lacking documents, can be passed over in favour of the next applicant in the queue.
Can a buyer join the ballot with a bank loan not yet approved?
Registration usually does not require a completed loan, but the booking fee is payable in cash on the day and the loan is needed within the weeks that follow. An in-principle approval and an affordability check before registration reduce the risk of committing to a unit that cannot be financed.
Is EC balloting the same as private condo balloting?
They follow a similar logic of random queue numbers, but ECs carry additional eligibility checks, and the booklet for each project sets out its own procedure, including an electronic ballot held a day before public booking in the example reviewed. The EC eligibility guide covers the qualifying conditions.
