Meanwhile, singles can either apply on their own or with up to three other singles.
But you'll have to be at least 35 years old, and can only apply for a 2-room Flexi flat in a non-mature estate.
There are two flat options for seniors sold via the BTO route. These are:

Be sure to apply for the HDB Flat Eligibility (HFE) letter before the BTO sales launch. It will inform you on your eligibility on the following:
Note that for this May 2023 HDB BTO, you'll need to do the following:
1. Preliminary HDB Flat Eligibility (HFE) check before you submit your BTO application
2. Apply for the HFE letter within 30 days of doing this preliminary check. You'll need the HFE letter when you go for the flat booking appointment.
You must meet the following criteria to be eligible for an HDB housing loan.
An HDB loan can finance up to 80 per cent of your flat's price or value (the lower of the two). The remaining down payment of 20 per cent can come from cash, CPF, or a combination of the two.
A private bank loan requires you to pay at least 5 per cent of your flat in cash. Another 20 per cent can be paid through a combination of cash or CPF. Up to 75 per cent of your flat price or value (the lower of the two) can be financed by the bank.
The bank’s mortgage officer will give you the details of any other requirements.
HDB will launch the sale of new flats through the BTO exercise every three months in February, May, August and November.
At the same time, they'll announce the locations and estimated number of units of the projects for the next BTO launch. You can browse through these details on HDB’s Flat Portal.
Every BTO launch has a one-week application period. During this time, you can apply for a flat online. There is a non-refundable administration fee of $10 to apply.
For the May 2023 HDB BTO exercise, the application period runs from May 30, 3pm to June 5, 11.59pm.
You are only able to apply for one flat type at one location for each launch, so do take the time to plan out the pros and cons list as soon as you find out about the available BTO exercises.
It’s not a first-come, first-basis. So you don't have apply right after HDB launches an exercise! During the week-long application period, HDB will update the BTO application rate daily (at 8am, 11am, 2pm and 5pm). So you can monitor the application rate in the meantime to gauge your chances of getting a BTO queue number.
Applicants tend to outnumber the available units, especially in mature estates. As such, a balloting process is used to decide who gets the flat (for more details on how the ballot works, visit the HDB website).
You will know the results of the ballot up to two months later. HDB will send you a notification as to whether you’re successful. Remember to check your email!
Once you've gotten your BTO queue number, you should be checking the HDB Flat Portal regularly to see the progress of the flat selection. Knowing which flats are left will help you shortlist the best unit for you before your BTO flat booking appointment.
If you're shortlisted, you'll be invited for an appointment to book a flat four weeks after the ballot results.
You'll have to bring the following documents to the appointment:
You’ll also need a valid HFE letter before you go for the flat booking appointment.
Bring your Nets card too! At this stage, you’ll need to pay the option fee.
Flat type | Option fee |
2-room Flexi | $500 |
3-room | $1,000 |
4-room and bigger | $2,000 |
The option fee will form part of the downpayment.
If you’re applying for the Deferred Income Assessment, you'll have to apply for it during the flat booking appointment. Head over to HDB’s website for more info on this.
Within nine months, you will be invited to sign the Agreement for Lease.
At this stage, you'll be required to pay for the following:
HDB will notify you of the exact date that the development will be finished. From there, all you need to do is wait to collect your keys.
Application for a BTO unit from start to finish will take at least four to five years, during which you and your partner should be financially prudent and start saving enough to pay for your mortgage as well as your renovation.
