If you need an HDB flat urgently, but can't afford to wait four or five years for a BTO flat, one way to fast-track the process is to buy an HDB Sale of Balance Flat (HDB SBF).
In this article, we'll explain what an HDB SBF is and how it compares against a BTO flat and Open Booking of Flat. And should you decide that you'd like to apply for an HDB balance flat, we'll also guide you through the eligibility criteria and application process for HDB Sale of Balance Flats 2021.
What Is the HDB Sale of Balance Flat (SBF)?
HDB SBF Scheme is essentially a housing sales exercise that pools together unsold flats (or HDB balance flats) from past BTO launches, remaining flats from Selective En-bloc Redevelopment Scheme (SERS) projects, and any flats repurchased by HDB.
The SBF exercise occurs twice yearly. In the first SBF exercise of 2021, 2,494 flats were on offer.
Previously, all unsold flats from HDB SBF exercises will be first offered through the ROF exercises. If these flats remain unselected, they will be made available for open booking.
However, in March 2020, the government announced the Re-Offer of Balance Flats (ROF) scheme would be removed to allow home buyers to obtain their flats more quickly.
With the removal of ROF exercises, all unsold BTO balance flats will be first be offered through the HDB Sale of Balance Flat scheme. If they remain unselected, these HDB Sale of Balance Flats will be then be offered for open booking, instead of going through another round of HDB ROF exercise like in the past.
HDB Build-to-Order (BTO) Flats vs Sale of Balance Flats 2021: What’s the Difference?
Under HDB’s Sale of Balance Flats scheme, you get to choose from a wider range of locations compared to the BTO scheme
Here are some of the key differences between HDB’s BTOs and HDB SBFs.
1. HDB Sale of Balance Flats Have a Shorter Waiting Period
The main difference between the HDB SBF and HDB BTO flat is the shorter waiting time.
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 3 to 4 years. But with construction delays, the estimated waiting times for flats launched this year and last year range between 3 to 5.5 years.
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). Therefore, you can get your flat a lot quicker.
This is especially great for young couples who do not want to delay marriage to have a home, or do not want to spend money on rental while waiting for their BTO unit to complete. Single unwed parents and seniors also stand to benefit from the shorter waiting time of HDB SBF exercises.
SBF launches happen twice a year, and coincide with some of the BTO sales launches. This year, HDB's Sale of Balance Flats 2021 exercise happened in May 2021, and the next launch is slated for November 2021.
Even though both HDB BTO and Sale of Balance Flats 2021 sales exercises occur at the same time, however, you can only apply for one scheme at any given time.
2. HDB’s Sale of Balance Flats Scheme Offers You More Locations to Choose From
Conversely, since the HDB SBF scheme pools together unsold flats from many different projects, HDB Sale of Balance Flat launches are located in both mature and non-mature estates across Singapore. While there are fewer total units available for sale, you have more locations and options to choose from when applying for an HDB balance flat.
3. You Have a Slimmer Chance of Selecting an HDB Balance Flat That You Like
When you apply for a flat under the BTO scheme, you’re basically balloting for a chance to be able to pick the best flat out of the bunch.
On the other hand, things are different when you apply for an HDB balance flat via the HDB SBF scheme.
Since HDB SBF sales are ‘leftover’ flats from previous sales exercises, these flats are 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.
Having said that, this isn’t the case for every unit offered through HDB SBF. Some may simply have ended up in the pool because previous buyers were picky, couldn’t afford them, or had to give up the unit due to other reasons. So, depending on your luck, you could actually have a unit that’s perfectly desirable.
4. There’s More Information About Sale of Balance Flats Compared to BTOs
Another perk of the HDB SBF 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 balance flats, as well as the ethnic quota when you want to apply for HDB SBFs.
5. HDB SBFs Are More Expensive Than BTO Flats
Whilst HDB's Sale of Balance Flats are still subsidised by the government, they are still more expensive than BTO flats. However, they still cost much lesser compared to HDB resale flats.
6. HDB SBFs Must Comply With Ethnic Race Policy (EIP)
Buying an HDB Sale of Balance Flat also comes with the race quota restriction: it might not be available for certain racial profiles, particularly Chinese.
7. It’s Harder to Secure an HDB Balance Flat
Since there is much fewer HDB Sale of Balance Flats units available compared to BTO flats, your chances of securing a Sale of Balance Flat is slimmer.
HDB Sale of Balance Flats (SBF) vs Re-offer of Balance Flats (ROF) vs Open Booking of Flats
In the past, any HDB Sale of Balance Flats that were not selected, were pooled together in another exercise known as the Re-offer of Balance flats (ROF).
Just like how HDB Sale of Balance Flats are the 'balance flats' from BTO exercises, HDB ROFs are the remaining flats that were not selected from previous HDB SBFs. Think of them as the HDB balance flats of the HDB balance flats.
However, as mentioned above, the HDB ROF exercise has been scrapped. Any balance flats from HDB SBF will be made available through an open booking system on HDB's portal.
Here’s a comparison table highlighting the key differences between HDB SBFs and Open Booking of Flats.

How Do I Buy an HDB Sale of Balance Flat?
Thinking of applying for an HDB SBF flat in 2021? Unfortunately, May's application period is over, but do look out for the HDB SBF launch in November on HDB's portal. You may also try your luck with Open Booking of Flats, available on the same portal.

1. Apply for Your HDB SBF Flat Online
Once HDB announces the sale of unsold flats, you can proceed to submit an online application within the application period, provided you meet all the eligibility criteria. Each launch is about a week-long, so you do have some time to make a decision among the flats.
2. Await Results and Get Your Finances in Order
Following this, if your application is successful, you will be shortlisted via a computer ballot. The results are usually announced in about three weeks.
If luck is on your side and you have a short queue number, then your chances of getting the flat you really want are much higher. First-time applicants and couples have higher chances of securing an HDB Sale of Balance Flat.

If you’re taking out a bank loan, you’ll need to request an Approval-in-Principle (AIP) letter from your bank.
