A ballot result from the Housing and Development Board (HDB) is not a flat. It is a position in a queue, and between that position and a set of keys lie a construction period, four or five visits or payments, and a sequence of documents that each change what the buyer owes and what the buyer would lose by walking away. The price of the flat is only one of the sums involved: an option fee, stamp duty, legal fees, registration and survey fees, an insurance premium and the first service charge all fall due at fixed points.

This guide follows a new flat bought in a Build-To-Order (BTO) exercise in Singapore from the day the ballot result arrives to the day the minimum occupation period starts running. It uses HDB's administrative annex for the June 2026 exercise, the MyNiceHome guides that HDB publishes for buyers, the CPF Board's page on housing expenses and one published HDB letter. How the ballot itself works, what Standard, Plus and Prime flats are and which grants exist are left to other articles. Where an official page could not be read on a point, the guide says so and does not fill the gap.

HDB, Annex B to the June 2026 BTO exercise, and HDB's published letter of 31 May 2021 for the forfeiture.

A ballot result is a queue position, not a flat

HDB's Annex B for the June 2026 exercise describes the mechanism in a few lines. Applicants are shortlisted by computer ballot, and HDB shortlists between 100% and up to 200% of the total flat supply, taking its quotas into account. Each shortlisted applicant receives a queue position. Applicants who are not shortlisted are told that the application was unsuccessful.

The upper figure matters. When up to twice as many households are shortlisted as there are flats, a queue position can sit beyond the number of flats on offer. Holding one is therefore an invitation to choose if flats remain when the turn comes, and the annex words it that way: applicants are invited to book "subject to availability of flats for their ethnic group when their turn is due". The last phrase refers to the ethnic quotas: a flat that is still unsold may no longer be available to a given buyer's group.

A queue position also ties the applicant's hands for a while. According to the same annex, an applicant whose queue position falls within the flat supply cannot apply in later BTO or Sale of Balance Flats exercises until after the booking appointment. The household is, in effect, committed to seeing that appointment through before it tries anything else.

From the result to the appointment

Two official timetables exist, and they are not identical. MyNiceHome's guide to buying a BTO flat, a page dated 29 June 2026, says that HDB emails the outcome of the ballot within 2 months after applications close and that the booking exercise starts about 4 weeks after the results are released. It adds that the booking exercise may run over several months.

Annex B gives the dates of one exercise. Applications for the June 2026 launch ran from Wednesday 17 June 2026 to Wednesday 24 June 2026; queue positions were to be communicated in August 2026; and booking is tentatively scheduled to commence in December 2026. For that launch the interval between results and the first appointments is therefore longer than the 4 weeks of the general guide. The annex is the document specific to the exercise, and a buyer's own letter from HDB is more specific still.

MyNiceHome says HDB notifies each buyer of the booking appointment about 2 weeks before its date. The time in between is for watching the supply shrink. The guide describes a watchlist on the HDB Flat Portal that notifies the buyer when units on it are booked by others, and Annex B notes that applicants can check the availability of flats for their ethnic group on the portal before going to the HDB Sales Office.

The booking appointment and the option fee

The appointment takes place at HDB Hub. MyNiceHome lists what to bring: identity documents, proof of the relationship between the applicants, and other documents where they apply, for example a certification of pregnancy or a child's certificate.

Three things happen at the appointment. The buyer chooses a unit from those still available. The buyer may add items under the Optional Component Scheme where the project offers it; MyNiceHome explains that their cost is added to the purchase price and that they are installed during construction, so the decision made that day changes every later percentage. And the buyer pays the option fee.

The option fee depends on the flat type. Annex B for June 2026 sets it at S$500 for a 2-room Flexi flat, S$1,000 for a 3-room flat and S$2,000 for a 4-room, 5-room or 3Gen flat, payable on booking. MyNiceHome gives the same scale and places Community Care Apartments in the S$500 band. The annex states that payment is made by debit card or eNETS through the AXS mStation application or an AXS e-Station. Both sources say the fee forms part of the downpayment: it is an advance on the next payment, not a charge on top of the price.

Young couples learn two things at this appointment without applying for either. MyNiceHome's guide for young couples, dated 13 April 2026, says HDB informs buyers when they book whether they qualify for Deferred Income Assessment and for the Staggered Downpayment Scheme. Both are described further down.

Not booking has a price of its own. Annex B says a first-timer family that does not book a flat when flats are available has its later applications moved to the second-timer category for one year, and stays there for another year if it again does not book. Other applicants who do not book cannot apply for any flat in later public sales for one year, and a non-selection count cancels the applicant's existing applications. HDB waives the count for an applicant who had 10 or fewer BTO flats to choose from, or five or fewer Sale of Balance flats.

Signing the Agreement for Lease

The second document is the Agreement for Lease. Annex B says HDB invites buyers to sign it within nine months after booking. MyNiceHome adds that the signing is done at HDB Hub and that identity documents are needed.

The downpayment is due at the signing, and its size depends on who lends. The annex puts it at 10% of the flat price for a buyer taking a housing loan from HDB and 20% for a buyer taking a loan from a financial institution, payable from CPF savings, cash or both. A buyer borrowing from a financial institution must produce the lender's Letter of Offer before signing, which means the bank loan has to be arranged during the nine months, not after them.

The loan ceilings explain the rest of the arithmetic. Annex B records that from the October 2024 BTO exercise the HDB loan covers at most 75% of the price, down from 80%, and that the limit for loans from financial institutions remains 75%. MyNiceHome's table for an HDB loan, or for no loan at all, shows 10% at the Agreement for Lease and 15% at key collection. Its column for a loan from a financial institution, re-read on 10 October 2026, is headed with a loan-to-value limit of 55%, not 75%. Under that heading it shows 20% of the price at signing in two variants, one with a minimum cash payment of 5% of the price and one with a minimum of 10%, the remainder coming from cash or CPF savings, and two amounts at key collection, 5% and 25% of the price. As a matter of arithmetic, 20% plus 5% leaves 75% to be borrowed and 20% plus 25% leaves 55%, so the column may describe two cases of which only one limit is labelled in the text that could be read. The page does not say which buyers each variant applies to, and the 55% heading does not match the 75% of the annex. The difference is recorded here as it stands, not resolved.

Who handles the legal work also depends on the loan. MyNiceHome says HDB acts as the buyer's solicitor when the loan is from HDB. With a loan from a financial institution the buyer appoints a private solicitor, usually from the bank's panel.

Stamp duty and legal fees, as official pages state them

MyNiceHome says stamp duty and legal fees are payable when the Agreement for Lease is signed, without giving amounts. The amounts are on the CPF Board's page on HDB option fees and housing expenses, published on 28 April 2026.

Buyer's Stamp Duty is charged in tiers. The CPF Board gives 1% on the first S$180,000 of the price, 2% on the next S$180,000, 3% on the next S$640,000 and 4% on the next S$500,000. The duty is rounded down to the nearest dollar, with a minimum of S$1. The page says the duty applies to documents relating to the purchase and is paid upfront with the legal fees, and it notes that Additional Buyer's Stamp Duty may apply to some buyers on top, a matter it refers to the tax authority.

For a flat bought from HDB with a mortgage to HDB, the CPF Board states the legal fee as a scale on the price: S$0.90 per S$1,000 on the first S$30,000, S$0.72 per S$1,000 on the next S$30,000 and S$0.60 per S$1,000 on the remainder. Where a bank lends and a private lawyer acts, the same page puts the cost at about S$2,500 to S$3,000 on average, a figure it gives as an average.

The example assumes a price of S$450,000, chosen only for the arithmetic, an HDB loan at the 75% ceiling and no optional components. The duty is 1% of S$180,000, then 2% of the next S$180,000, then 3% of the remaining S$90,000. The legal fee applies the three rates to S$30,000, S$30,000 and S$390,000. The downpayment of S$45,000, the S$67,500 at key collection and the loan of S$337,500 add up to the price.

The CPF Board also lists fees of a fixed amount. Which of them apply to a given purchase depends on the loan and on who acts, and the page read for this guide was not specific on every line, so they are shown as the Board lists them and not added up.

On paying these sums, the CPF Board states that Ordinary Account savings can pay legal fees and stamp duty in full, and that for a property still under construction the stamp duty is paid directly through CPF. For a completed property the order is reversed: the buyer pays in cash first and claims reimbursement from CPF afterwards. Whatever is drawn from the Ordinary Account for the purchase, legal fees and stamp duty included, has to be refunded to the account when the flat is sold. The Board's page says option fees cannot be paid with CPF, in a passage placed with its section on resale flats; MyNiceHome describes the option fee for a new flat as paid in cash.

Paying the downpayment in two parts

Two arrangements soften the signing for young couples, and both are assigned by HDB at booking and not applied for.

The Staggered Downpayment Scheme splits the downpayment into two instalments: a lower one at the Agreement for Lease and the remainder at key collection. MyNiceHome's guide for young couples sets three conditions. Both applicants are first-timers, or one is a first-timer and the other a second-timer. The couple applied for its HDB Flat Eligibility letter on or before the younger applicant's 30th birthday. And the flat booked is an uncompleted flat of 5-room or smaller. The guide says the first instalment depends on whether the loan is from HDB or a bank and on whether Deferred Income Assessment applies, but gives no percentages.

Deferred Income Assessment is for couples whose income does not yet describe them. MyNiceHome's condition is that at least one applicant is a full-time student or a full-time National Serviceman, or completed full-time studies or National Service within the 12 months before the application for the eligibility letter. For such a couple the assessment for the Enhanced CPF Housing Grant and for an HDB housing loan is made closer to key collection instead of at application.

Annex B supplies the one percentage that could be read. From the June 2024 BTO exercise, young couples eligible for Deferred Income Assessment pay 2.5% of the flat price as downpayment, and the balance is payable when the flat is ready for key collection. On the S$450,000 flat of the worked example, 2.5% is S$11,250, against S$45,000 at the full 10%. The relief is one of timing only. If the HDB loan again covers 75% of the price, the other 25% is still S$112,500, and S$101,250 of it moves to the day the keys are handed over. The annex also mentions a Deferred Downpayment Scheme alongside the staggered one, without describing it.

The wait for completion

None of the pages read gives a construction period, and none is given here. What MyNiceHome does describe is how a buyer follows progress: through HDB's online service for checking an application for a new flat purchase, which shows the project's Probable Completion Date.

The wait is not a pause in the buyer's obligations. MyNiceHome asks buyers to report changes in their household or their financial circumstances to HDB as soon as possible. A purchase rests on the facts of the application, and a couple assessed late under Deferred Income Assessment will have its grant and its loan settled on the figures of the later date.

A household that already owns a flat has a deadline that begins at the other end of the wait. Annex B says that after collecting the keys, buyers have up to six months to dispose of their existing flat. It also mentions a contra facility or a temporary loan, which may be available once HDB has approved the resale application for the existing flat and which is redeemed from the net sale proceeds.

Key collection day

MyNiceHome says HDB notifies the buyer by email and SMS within 2 weeks before the key collection appointment, which is held at HDB Hub. The buyer brings identity documents and the Certificate of HDB Fire Insurance, and needs Singpass access and a digital device to apply for the CPF withdrawal online.

The guide lists four payments for that day:

1. the balance of the purchase price, from cash, CPF savings including housing grants, or the housing loan;
2. stamp duty on the mortgage and legal fees;
3. the Home Protection Scheme premium, payable to the CPF Board, where the instalments of an HDB loan are paid with CPF;
4. the first month's service and conservancy charges, payable to the Town Council.

Fire insurance is a condition, not an item on the day's bill. MyNiceHome says a buyer with an HDB loan must buy HDB fire insurance from HDB's appointed insurer with cover starting on the key collection date, and must renew it every 5 years while the loan is outstanding. The CPF Board gives the cost: a five-year premium of S$1.11 to S$6.68, depending on the size of the flat. The Home Protection Scheme is a different cover. The CPF Board describes it as mortgage-reducing insurance that protects against losing the flat through death, terminal illness or total permanent disability; its premium depends on the case and no amount is published on the page read.

The loan follows the keys. With an HDB loan, MyNiceHome says the loan is disbursed at key collection and the monthly instalments start on the 1st day of the month after it.

One more deadline starts that day for couples who applied as fiancé and fiancée: MyNiceHome says they must solemnise their marriage within 3 months of collecting the keys.

The occupation period starts with the keys

MyNiceHome's page on flat types, dated 24 June 2026, defines the minimum occupation period as the period during which the owners must live in the flat before they can sell it on the resale market. It is calculated from the date the keys are collected. Standard flats carry five years; Plus and Prime flats, at least 10 years.

Two consequences follow from that starting point. The first is that the clock is tied to an event, not to a calendar promise. In its published letter of 31 May 2021, HDB wrote that the period runs from the point of key collection, which can be earlier or later than the estimated completion date of the project. The time spent waiting for the flat counts for nothing towards it.

The second is that the period measures occupation. MyNiceHome says time during which the owners do not occupy the flat is excluded, for example when the whole flat is rented out or when the lease has been infringed. During the period the owners cannot sell the flat, rent out the whole flat, acquire a private residential property or apply for another BTO flat, though spare bedrooms may be rented out if HDB's other criteria are met. The page says enforcement for non-occupation ranges from a financial penalty to compulsory acquisition of the flat, and that an owner can check whether the period has been met through HDB's online service for flat details.

Cancelling after booking: what the pages confirm

A buyer's exposure grows at each stage, and the official pages read for this guide document the stages unevenly.

Before booking, the cost of withdrawing is the non-selection rule set out above: a year in the second-timer category for a first-timer family, a year's bar on applying for others, and the cancellation of existing applications.

After the Agreement for Lease is signed, the cost is a share of the price. HDB's letter of 31 May 2021 states that a buyer who cancels after signing will forfeit 5 per cent of the flat purchase price. On the S$450,000 flat of the worked example that is S$22,500, which is half of the S$45,000 paid as a 10% downpayment and twice the S$11,250 paid by a couple on the 2.5% instalment. The same letter says HDB will consider appeals to waive the forfeiture or the occupation period on a case-by-case basis. It dates from 2021, and no later official statement of the percentage was read.

What this guide leaves open

Several items a buyer will meet are missing from the pages that could be read, and they are named so that the figures above are not stretched to cover them.

The first instalment under the Staggered Downpayment Scheme is known only for couples on Deferred Income Assessment, at 2.5%; the percentages for other eligible couples, by type of loan, were not read. The rate of stamp duty on the mortgage paid at key collection, the Home Protection Scheme premium, the amount of the service and conservancy charges and the premium for each flat type within the fire insurance range are not on the pages read. Nor is the treatment of rounding and tax on HDB's legal fee scale for a new flat, or the allocation of each fixed fee between new and resale purchases.

The downpayment for a buyer borrowing from a financial institution is 20% at signing according to Annex B, but the loan ceiling for that case is stated as 75% in the annex and headed 55% on MyNiceHome, as noted above. The length of construction is not on the pages read. And the two cancellation points in the callout remain unconfirmed.

Each signature moves the buyer's stake up a step: a queue position, then an option fee, then a downpayment, then a lease with years of occupation attached.
