HDB's BTO rules give first-timer families more ballot chances and the largest share of flats in each of the 7 quota categories on this page, with smaller shares set aside for second-timer families.

Who counts as a second-timer, and who is treated as a first-timer
HDB's couples and families page defines the second-timer through housing subsidies taken.
If you and/ or any core member(s) have taken a housing subsidy, you are considered a second-timer.
A subsidised housing unit refers to: a flat bought from HDB; a resale flat bought on the open market with CPF housing grant(s); a Design Build and Sell Scheme (DBSS) flat bought from a property developer; an EC unit bought from a property developer; other forms of housing subsidy (e.g., enjoyed benefits under the Selective En bloc Redevelopment Scheme (SERS), privatisation of HUDC estate, etc.).
Mixed couples are covered by their own line on the modes of sale page.
Couples comprising a first-timer and second-timer are treated as first-timer families with the same priority benefits and privileges.
HDB also names a narrower first-timer group inside the first-timer families.
First-timer families who meet all the following eligibility criteria may qualify for the First-Timer (Parents & Married Couples), or FT(PMC), category: families with at least 1 Singapore Citizen child aged 18 and below, or married couples aged 40 and below (this includes married couples who are expecting and have a doctor's certification of the pregnancy); never owned or sold a residential property before, including an HDB flat; did not have a chance to book a BTO/ SBF flat in the past 5 years prior to their flat application. HDB will assess and inform you about your eligibility after you have submitted your flat application.
How many ballot chances each household type gets
At the end of the application period, HDB will place all eligible applications through a computerised ballot to determine the queue order to book the flats.
HDB's table lists each household status on its own row.
BTO allocation of ballot chances by household status: First-Timer (Parents & Married Couples) 3; other first-timer families/ couples 2; second-timer families 1; seniors 1; first-timer singles 1.
The first-timer family rows differ because of the FT(PMC) category.
FT(PMC) applicants receive 1 additional ballot chance when applying for the BTO/SBF exercises, on top of the 2 ballot chances received as a First-Timer family, for a total of 3 ballot chances for any flat type in any estate. The total is capped at 5 ballot chances.
Additional ballot chances
HDB has announced additional chances, both for first-timer families. They are stated on the modes of sale page.
From the February 2027 sales exercise, first-timer families with or expecting children will receive 1 additional ballot chance for each Singapore Citizen child aged 18 and below, for all BTO and SBF flat applications. First-timer families unsuccessful in 2 or more BTO applications for a Standard flat can also receive 1 additional ballot chance for every subsequent Standard BTO application, capped at 2 additional chances; this does not apply to Plus and Prime BTO flats.
HDB's table sets out the second kind by the number of earlier unsuccessful Standard BTO applications.
Ballot chances by number of previous unsuccessful BTO applications for Standard flats, 0 or 1: typical ballot chances 3 for FT(PMC) and 2 for non-FT(PMC); additional ballot chances 0; total ballot chances 3 for FT(PMC) and 2 for non-FT(PMC).
Ballot chances by number of previous unsuccessful BTO applications for Standard flats, 2: typical ballot chances 3 for FT(PMC) and 2 for non-FT(PMC); additional ballot chances 1; total ballot chances 4 for FT(PMC) and 3 for non-FT(PMC).
Ballot chances by number of previous unsuccessful BTO applications for Standard flats, 3 or more: typical ballot chances 3 for FT(PMC) and 2 for non-FT(PMC); additional ballot chances 2; total ballot chances 5 for FT(PMC) and 4 for non-FT(PMC).
Worked example: how the chances add up for one family
The examples below only add up the rows of HDB's table above. They are illustrations of the arithmetic, not predictions of any result, and they assume the rules apply to the exercise in question. Take a family that meets the FT(PMC) criteria. With 0 or 1 earlier unsuccessful Standard BTO applications it has 3 chances. After 2 unsuccessful Standard applications it has 3 plus 1, which is 4. After 3 or more it has 3 plus 2, which is 5, and that matches the cap of 5 that HDB states for FT(PMC) applicants.
Now take a first-timer family that does not meet the FT(PMC) criteria. It starts at 2 chances. After 2 unsuccessful Standard applications it has 2 plus 1, which is 3. After 3 or more it has 2 plus 2, which is 4. A second-timer family stays on 1 chance on the ballot-chances row, because the additional chances on HDB's page are written for first-timer families.
The third case is the one that removes chances. If that FT(PMC) family reaches 5 chances, then incurs a non-selection count by not booking when invited, its next applications go in the second-timer category for a year and the accumulated additional chances reset to 0. That puts it on 1 chance for that year, down from 5. The rule itself sits under the heading on when a first-timer stops being treated as one.
Flat supply set aside for each group
More flats are allocated to first-timer families as they have more pressing housing needs.
For second-timer families, up to 20% of the public flat supply will be set aside for them.
If there are more second-timer families than the flat supply set aside for them, not all of them will be successful in their flat application.
For first-timer families, as their flat allocation quota is at least a specified percentage, they can receive queue numbers bigger than the flat supply set aside for them.
HDB sets the split by flat type and by project class. The tables below are for non-seniors in a BTO exercise. FPPS is the Family and Parenthood Priority Scheme. FCS (Proximity) is the Family Care Scheme (Proximity). ASSIST is the Assistance Scheme for Second-Timers (Divorced/Widowed Parents).
BTO quotas in Standard projects
BTO flat distribution for non-seniors, Standard flats, 2-room Flexi: first-timer families FPPS 10%, FCS (Proximity) 5%, Others 5%; second-timer families ASSIST 5%, FCS (Proximity) 5%, Others 5%; first-timer singles FCS (Proximity) 30%, Others 35%. For 2-room Flexi flats, the allocation quota is among the non-senior public supply.
BTO flat distribution for non-seniors, Standard flats, 3-room: first-timer families FPPS 40%, FCS (Proximity) 30%, Others 10%; second-timer families ASSIST 10%, FCS (Proximity) 5%, Others 5%; first-timer singles FCS (Proximity) NA, Others NA.

Within the FPPS quota, first priority is given to FT(PMC)s who apply for a 4-room or smaller flat in Standard projects.
BTO quotas in Plus projects
BTO flat distribution for non-seniors, Plus flats, 2-room Flexi: first-timer families FPPS 10%, FCS (Proximity) 5%, Others 5%; second-timer families FCS (Proximity) 5%, Others 10%; first-timer singles FCS (Proximity) 30%, Others 35%. For 2-room Flexi flats, the allocation quota is among the non-senior public supply.
BTO flat distribution for non-seniors, Plus flats, 3-room and bigger: first-timer families FPPS 40%, FCS (Proximity) 30%, Others 20%; second-timer families FCS (Proximity) 5%, Others 5%; first-timer singles FCS (Proximity) NA, Others NA.

For 2-room Flexi flats, the allocation quota is among the non-senior public supply.
BTO flat distribution for non-seniors, Prime flats, 3-room and bigger: first-timer families FPPS 40%, FCS (Proximity) 20%, Others 30%; second-timer families FCS (Proximity) 3%, Others 7%; first-timer singles FCS (Proximity) NA, Others NA.
Priority schemes HDB lists
Priority schemes enhance your chances in the computer ballot for flats offered in the BTO and SBF exercises. You may apply for 1 priority scheme, if your household meet the eligibility conditions when you apply for your HDB Flat Eligibility (HFE) letter. However, priority schemes do not guarantee a favourable queue number for flat selection.
If you qualify for the Family and Parenthood Priority Scheme (FPPS), you may apply for 1 other priority scheme, such as the Family Care Scheme (FCS) (Proximity) or Third Child Priority Scheme (TCPS).
A computerised ballot is conducted for each priority scheme. For example, for a first-timer family with 3 children and is eligible for both the TCPS and FPPS, their application will first be balloted under the TCPS. If that ballot is unsuccessful, their application is balloted again under the FPPS.
The schemes on HDB's priority schemes page are below, one by one.
Family and Parenthood Priority Scheme (FPPS): this scheme helps first-timer married couples with child(ren) and young married couples to get their flat more easily. Up to 40% of the public flat supply for BTO flats is set aside for the applicants.
Family Care Scheme (FCS) (Proximity): this scheme helps parents and their child(ren), married or single, to live with or near each other for mutual care and support. From the July 2025 sales exercise onwards it replaces the previous Married Child Priority Scheme (MCPS) and the Senior Priority Scheme (SPS) (living with or near parents/ married child).
FCS (Proximity) allocation for BTO and SBF flats: first-timer families, up to 30% of the public supply; second-timer families, up to 5% of the public supply for BTO flats and up to 3% for SBF flats.
Family Care Scheme (FCS) (Joint Balloting): from the October 2025 sales exercise onwards, parents and their child(ren), married or single, can jointly apply for 2 units in the same BTO project where there are 2-room Flexi or 3-room flats offered. This scheme replaces the Multi-Generation Priority Scheme (MGPS). If the household is married, it must be a first- or second-timer family applying up to a 5-room flat.
Third Child Priority Scheme (TCPS): this scheme helps families with 3 or more children. From the June 2026 BTO exercise, the TCPS is enhanced. Flat allocation is up to 10% of BTO flats, and up to 10% of SBF flats.
Assistance Scheme for Second-Timers (Divorced/ Widowed Parents) (ASSIST): this scheme supports divorced or widowed persons with children. Flat allocation is up to 5% of 2-room Flexi flats and up to 10% of 3-room flats in Standard projects offered in BTO exercises, as part of the flats set aside for second-timer families.
Senior Priority Scheme (SPS) (near existing home): this scheme helps seniors who wish to buy a 2-room Flexi flat to age-in-place in a familiar environment. The 2-room Flexi flat must be within 4 km of your owner-occupied property (either HDB flat or private residential property).
Tenants' Priority Scheme (TPS): this scheme helps tenants of HDB rental flats to purchase their own home. The quota is up to 10% of 2-room Flexi and 3-room BTO/ SBF flats, shared with applicants under the Selective En bloc Redevelopment Scheme, Relocation, Resettlement, and SLA's acquisition.
Using a priority scheme: what HDB says about picking and checking
HDB asks for a single priority request when you submit the application, and it checks the claim afterwards.
Flat buyers may select 1 priority scheme when submitting their flat application to enhance their chances in the ballot. HDB will assess and inform you about your eligibility after you have submitted your flat application.
One scheme has a distance test that you can run during the exercise itself.
You can use the 'Distance Enquiry for FCS' e-Service to check whether you meet the proximity condition of 4 km to qualify for the Family Care Scheme (FCS) (Proximity). This e-Service is available during the application period of each sales exercise.
If the request needs changing, HDB allows it while the application period is open.
During a sales exercise, you can log in to My Flat Dashboard to change your correspondence address, contact details or priority scheme request, if applicable.
Some schemes need a certificate on booking day, so the paperwork follows the scheme you picked.
At flat booking, if you applied under the Third Child Priority Scheme (TCPS), Family and Parenthood Priority Scheme (FPPS) or Assistance Scheme for Second-Timers (Divorced/ Widowed Parents) (ASSIST), you will need either a doctor's certification of pregnancy or your child's birth certificate.
At flat booking, if you are buying a flat under the Family Care Scheme (FCS) (Joint Balloting) or FCS (Proximity), you will need your birth certificate and your parents' marriage certificate.
When a first-timer stops being treated as one
HDB's application page ties first-timer priority to booking a flat when invited. The cases differ.
For first-timer families, including those under the FT(PMC) category, with 1 non-selection count, subsequent flat applications will be placed in the second-timer category for a 1-year period. Any additional ballot chances accumulated from previous unsuccessful BTO applications for Standard flats will be set to 0.
For first-timer singles and second-timer families, after incurring 1 non-selection count, you will not be able to participate in any sales exercises for a 1-year period.
An application is unsuccessful if you did not receive a queue number to book a flat, or the flats have all been booked before your queue number is due.
What if your plans or your details change after you apply
A ballot application is built from your HFE letter, so changes to the household usually mean going back to the start.
During a sales exercise, all details of the household in the flat application must be the same as the approved HFE letter. For any changes in household particulars or financial circumstances, such as income, you must cancel both your HFE letter and flat application, and apply for a fresh HFE letter. As an HFE letter application takes about a month to process after HDB receives all the required documents, you would not be able to apply for a flat in the ongoing sales exercise.
The town and flat type are tied to the application as well.
During a sales exercise, to change the town or flat type you applied for, you must cancel your existing flat application and re-apply online during the application period with the payment of an administrative fee of $10 (inclusive of GST). After the sales exercise, you cannot change the town or flat type you applied for.
Cancelling is free while the application period is open.
There will be no penalty if the flat application is cancelled during the sales exercise application period. You can log in to the HDB Flat Portal and use My Flat Dashboard to cancel your flat application instantaneously before the end of the application period.
After the period closes, a cancellation request does not remove you from the ballot if it arrives before the results.
If you cancel your flat application after the sales exercise application period but before booking a flat, there is no financial forfeiture. A request received before the release of ballot results cannot be processed, and your application will be included in the computer ballot and assigned a queue position, where applicable. Once a flat application is cancelled, it cannot be reinstated.
A household that has not yet applied for an HFE letter when an exercise opens has a different problem.
Flat buyers who have yet to apply for an HFE letter may apply for one when the 'Apply for HDB Flat Eligibility (HFE) Letter' e-Service resumes. They may then apply for a new flat in HDB's subsequent sales exercises with a valid HFE letter.
What the ballot result does and does not decide
The ballot sets a queue order, and the queue order sets when you are invited to book.
HDB will inform all applicants of the outcome of their application. You may check the status of your application when the ballot result is announced.
A place inside the flat supply has a consequence for what else you can apply for.
If your queue position is within the flat supply, you will not be eligible to apply for a flat in the subsequent BTO/ SBF exercises until after your flat booking appointment.
HDB also lists a case where the penalty for not booking is waived.
HDB will waive the non-selection count for applicants with 10 or fewer BTO flats to choose from, or 5 or fewer SBF flats to choose from.
Common mistakes with the ballot
Four misreadings come up when people read the tables above.
The first is treating the quota percentages as odds. They are shares of the flat supply set aside for each group, and the ballot chances are a separate count.
The second is stacking schemes without reading the rules. HDB allows one priority scheme, with a stated exception for households that qualify for FPPS, and no scheme guarantees a good queue number.
The third is assuming first-timer status is permanent. The non-selection rule on this page can move a first-timer family into the second-timer category for a year.
The fourth is treating a ballot result as a flat. A queue number is an invitation to book, and it only pays off if flats are still unbooked when your number is called.
Does this apply to the November 2026 exercise?
HDB's pages we read do not say which exercise each rule starts or ends with, apart from the start point in the additional-chances line above. We do not claim that the tables apply to the November 2026 exercise.
HDB's Modes of Sale page, read on 9 October 2026, shows 'Last updated 23 August 2026'. The page does not name the November 2026 exercise.
HDB's news release of 1 October 2026 does not mention ballot chances, flat quotas or priority schemes. It states that HDB will launch about 7,960 flats in the upcoming BTO exercise in November 2026.
HDB's news release of 1 October 2026 states that more details will be shared during the sales exercise.
Common questions
Do second-timer families get fewer ballot chances than first-timer families?
Yes, on HDB's table they sit on a lower row. BTO allocation of ballot chances by household status: First-Timer (Parents & Married Couples) 3; other first-timer families/ couples 2; second-timer families 1; seniors 1; first-timer singles 1.
Is a couple with one first-timer and one second-timer treated as second-timers?
No. Couples comprising a first-timer and second-timer are treated as first-timer families with the same priority benefits and privileges.
Can I use more than one priority scheme?
Generally one. Priority schemes enhance your chances in the computer ballot for flats offered in the BTO and SBF exercises. You may apply for 1 priority scheme, if your household meet the eligibility conditions when you apply for your HDB Flat Eligibility (HFE) letter. However, priority schemes do not guarantee a favourable queue number for flat selection.
Can a first-timer family be treated as a second-timer?
Yes, in one case HDB states. For first-timer families, including those under the FT(PMC) category, with 1 non-selection count, subsequent flat applications will be placed in the second-timer category for a 1-year period. Any additional ballot chances accumulated from previous unsuccessful BTO applications for Standard flats will be set to 0.
Is there a set share of flats for second-timer families?
HDB sets a share in its BTO tables. For second-timer families, up to 20% of the public flat supply will be set aside for them.
Can I change my priority scheme or cancel after I apply?
You can while the application period is open. There will be no penalty if the flat application is cancelled during the sales exercise application period. You can log in to the HDB Flat Portal and use My Flat Dashboard to cancel your flat application instantaneously before the end of the application period.
How do I find out whether HDB treats me as a first-timer or second-timer?
Apply for an HDB Flat Eligibility (HFE) letter on the HDB Flat Portal. HDB says the letter assesses your eligibility to buy a flat, and informs second-timers of the resale levy or premium payable for a subsidised flat from HDB.
