The HDB Sale of Balance Flats 2025 exercise will be held in February 2025. This upcoming Sale of Balance Flats (SBF) exercise will see more than 5,500 units on offer, making it the largest SBF launch ever.
In the past, the exercise was held twice yearly in May and November. However, the stabilisation of BTO application rates saw HDB announcing that there will only be one SBF exercise and three BTO exercises held in a year from 2024 onwards.
In this article, we’ll explain the HDB SBF 2025 exercise and how it compares against the BTO and OBF launches. We’ll also guide you through the eligibility criteria and application process.

What Is the Sale of Balance Flats Exercise?
SBF scheme is essentially an exercise that pools unsold flats from past BTO launches, surplus flats from Selective En bloc Redevelopment Scheme (SERS) projects, and any flats repurchased by HDB.
The HDB Sale of Balance Flats 2025 is a way first-time homebuyers who can’t wait four or five years for a BTO flat or pay for an HDB resale flat to secure an affordable home.
Number of SBF Units Launched (Nov 2020 to Feb 2025)
| February 2025 | About 5,500 |
| February 2024 | 1,588 |
| May 2023 | 1,500 |
| Nov 2022 | 1,071 |
| May 2022 | 1,952 |
| Nov 2021 | 1,798 |
| May 2021 | 2,494 |
| Nov 2020 | 5,220 |
The last HDB Sale of Balance Flats 2024 exercise has concluded. Of these SBF 2024 flats, about 12% of the SBF units on offer were completed, with the rest in various stages of construction.
According to HDB, the 2024 SBF application rates for first-timer families for 3-room and bigger flats was 10.5. If you are interested in the full breakdown of SBF 2024 application rates for each neighbourhood and for the different flat types, you can view the 2024 SBF application rates here.
HDB BTO Flats vs SBF Flats: What’s the Difference?
1. SBF 2025 Units on Offer Have a Shorter Wait Time Than BTO Flats
Since the construction of BTO flats will only begin if at least 70% of flats are booked, this means the process is longer as the waiting time is usually about three to four years. These factors can weigh on first-time homebuyers who are considering marriage and having kids soon.
In contrast, HDB SBF launches sell leftover flats from projects that are either under construction or have already been completed (that are ready to be moved into). As a result, you can anticipate receiving your home much sooner.
This is especially great for young couples who do not want to delay marriage until they have a home, or do not wish to spend money on rental homes while waiting for their BTO unit to complete. Single unwed parents and seniors also stand to benefit from the shorter waiting time for the SBF exercise.
In the upcoming HDB Sale of Balance Flats 2025 exercise, four in 10 of the units will be completed. The rest of the units will be progressively completed from 2025 to 2028.
2. HDB SBF Launches Offer More Locations to Choose From Than BTO Flats
Since the scheme pools unsold flats from many projects, the HDB SBF launches are located in both mature and non-mature estates. While there are fewer total units available for sale, you have more locations and options to choose from.
The flat supply for the Sale of Balance Flats 2024 exercise was set at 1,588 flats. The Sale of Balance Flat 2024 location were for homes in areas such as Ang Mo Kio, Clementi, Sengkang and Jurong West. The bulk of the units offered were 4-room and 2-room Flexi units.
The location of the upcoming HDB Sale of Balance Flats 2025 units have yet to be announced. But it is likely we can expect many available locations and a wide range of SBF 2025 unit types due to the bumper crop of units offered in the HDB Sale of Balance Flats 2025 exercise.
3. You May Not Get a Unit You Like
When you apply for a BTO flat, you’re essentially balloting for the opportunity to choose the best flat out of the bunch. However, applying for a flat under the Sale of Balance Flats exercise is different.
Since the HDB SBF units available are ‘leftover’ flats from previous sales exercises, these flats are sometimes considered ‘undesirable’ by previous buyers due to the units’ location. For example, lower floor units that are close to the centralised rubbish chute disposals, west-facing units, or units with obstructed views.
Likewise, you may not like where the SBF 2025 units are located or find a home in a neighbourhood you want in the HDB Sale of Balance Flats 2025 launch.
Having said that, this isn’t the case for every leftover flat. Some desirable units might have ended up in the SBF 2025 pool due to previous buyers being indecisive, financial constraints, or having to give up the unit for other reasons like a breakup. Therefore, depending on your luck, you might just find your perfect SBF 2025 unit.
4. There’s More Information About SBF Units Compared to BTO Flats
Another perk of the sale of balance scheme is that HDB provides information down to the last detail.
In addition to the location, type, flat size, and map (things that are provided in BTO sales), you will also know the block and unit numbers of the SBF 2025 flats, as well as the HDB quota.
For example, once the HDB Sale of Balance Flats 2025 release date is announced, more information about the HDB Sale of Balance Flats 2025 units will be made available. Homeowners could look up BTO projects and view floor plans before making a decision on their SBF 2025 unit.
5. SBF Units Could Be Slightly More Expensive Than BTO Flats
Even though the government also subsidised HDB’s Sale of Balance Flats units, they can be slightly more expensive than BTO flats. However, they still cost much lesser compared to HDB resale flats.
6. SBF Units Are Subject to the Ethnic Race Policy (EIP)
Buying an HDB Sale of Balance Flats unit also comes with a race quota restriction: it might not be available for certain racial profiles, particularly for Chinese persons.
7. It’s Harder to Secure an SBF Unit than a BTO Flat
Since there are much fewer HDB SBF units available compared to BTO flats and there is more interest in SBF flats due to the shorter waiting time, your chances of securing a unit tend to be slimmer.
Already, if you compare 2024 SBF application rates to that of 2024 BTO application rates, you’ll see that the competition for SBF units is fiercer. The same will likely apply for the SBF 2025 units.
Additionally, the SBF exercise favours first-timer families who are parents or already married the most. Those who qualify under the FT(PMC) scheme get three ballot chances, whereas other first-timer families/couples only get two ballot chances. So if you’re only engaged to be married, this is something you’ll want to take note of.
Second-timer families and singles get only one ballot chance.

How Do I Buy an HDB SBF 2025 Unit?
1. Secure Your HFE Letter
You need a valid HDB Flat Eligibility (HFE) letter if you intend to apply for the upcoming SBF 2025 launch. Your HFE letter is valid for nine months.
As it takes 21 working days for you to receive the outcome of your HDB HLE letter and longer during peak periods (i.e. before and during the month of a BTO or SBF launch), do apply for your letter early. Don’t leave the HFE letter application to the last minute!
2. Apply for the SBF 2025 Exercise
From the HDB HFE letter, you’ll know how much you can loan and the grants available to you. Then, you can work backwards to figure out what type of housing you can afford.
When it is announced that the HDB Sale of Balance Flats 2025 is launched, you can proceed to submit an online application within the application period for your ideal flat. This is provided you meet all the eligibility criteria.
Each launch is about a week-long, so you do have some time to decide between the flats.
3. Await the Results
Following this, if your application is successful, you will be shortlisted via a computer ballot. The HDB SBF results are usually announced in about one and a half months.
If luck is on your side and you have a short queue number, then your chances of getting the flat you want are much higher. Check out the SBF flat distribution for non-seniors in mature and non-mature estates on the HDB website to better understand your chances.
4. Book Your Flat With HDB and Get Your Finances in Order
Congratulations if you’re one of the lucky ones who got an SBF flat! You will then be invited to book your flat according to your allocated queue number and unit availability. You’ll be shown what’s available to you when you go to the HDB Hub for your appointment, and if you like what’s available, you can make the booking on the spot.
This is when you will also need to pay the Option fee: it’s $1,000 for a 3-room flat and $2,000 for a 4-room and bigger flat. If you are buying a 2-room Flexi flat, the option fee is $500.
Also, you’ll want to get your finances to purchase your flat. If you’re taking out a bank loan or one from a participating FI, you should move to get prequalified and secure your In-Principle Approval (IPA).
