Although the SOP for buying an HDB BTO flat has been well-documented, buying a flat via HDB’s Sale of Balance Flats (HDB SBF) or the new open booking system is a little less talked about.
- HDB SBF launches happen twice a year — typically May and November. The flats here are unsold units from previous BTO launches.
- Then, any remaining unsold units after SBF will be available through HDB Open Booking of Flats. These units were meant to be available all year round. However, Open Booking somehow ended up no longer… open for booking any time of the year. Open Booking is currently ongoing and applications will open on 12 October 2022.

To find the address of the SBF unit you’re interested in, go to the HDB website, click onto SBF, and go to the “Finding a Flat” webpage. You will be shown a map, and individual estates’ details will show up.
For example, if I’m looking for a SBF unit near Hougang MRT station, this is what I will see on the map:
If you were to click into the SBF Hougang Ave 5 bubble, a dedicated webpage will pop-up to show you more details of the available SBF units in this estate:
You will then be able to select your flat size of choice, your ethnicity, and the blocks that are available to you. Then, you’ll be able to see the exact unit number:

2. What is Sale of Balance Flat (SBF)?
The main advantage that buying a balance flat gives is the chance to jump the [BTO] queue. After all, the standard HDB BTO route does have some disadvantages:
- Fewer options: HDB BTOs are launched only a few times a year, and they may not be located in the estate you want.
- Scarcity: Even if HDB has released a suitable location this time round, there’s no guarantee you’ll get a flat because everyone has to go through the dreaded balloting process. Getting invited to select a flat in a “hot” BTO development like Kallang/Whampoa is like striking 4D.
- Long waiting time: Finally, after you manage to secure a BTO flat, there’s still a long-ass wait of at least 4 to 6 years for most BTOs. That’s another 1,460 days you have to spend living at your in-laws’ place. ‘Nuff said.
Key advantages of an HDB Sale of Balance Flat (SBF) include:
- More locations to choose from: Not limited to the 3 or 4 areas in the current BTO launch
- Shorter wait: Because the flat is already under construction (in some cases, ready to move into)
- Viewing: More often than not, your SBF project would already be halfway or even done. You can walk up to the estate to view and check out nearby amenities and try taking the MRT or bus to your workplace etc. If the project is already up, you can even go right up to the unit to check our your potential neighbours.
- Easier to gauge chances: You can see how many flats are available for your ethnicity
But there are also big disadvantages, such as:
- Slim chances: Because the supply is much smaller than HDB BTOs, the chances of a successful application can be slim
- Less choice: Want a high floor corner unit? These might have been snapped up by BTO buyers. If the high floor units are available, they may be ridiculously expensive (that’s why people are not buying)
- Ethnic quota restrictions: Flats may not be available for certain races, especially Chinese
- No cost savings: Sadly, HDB doesn’t have a “reduced to clear” policy for their unsold flats. In fact, balance flats may sometimes cost a bit more
3. Sale of Balance Flats (SBF) vs Built to Order (BTO)
There are 2 ways to get a balance flat:
First, there is the HDB Sale of Balance Flats (SBF), which comprises mainly flats left over from previous HDB BTO launches. These either did not get selected by the BTO ballot winners, or were selected but later given up (e.g. if the applicants decided to break up or go for condo).
So, what if there are any any leftover, leftover flats? Well, they’ll be offered under HDB’s Open Booking of Flats. Here are the differences:
|HDB Sales of Balance Flats||HDB Open Booking of Flats|
|When it’s available||Twice a year (e.g. May & Nov)||All the time|
|Application period||1 week (during sales launch)||Generally open throughout the year (though will only reopen in Sep 22)|
|What flats are available||Leftover flats from previous HDB BTO launch||Leftover flats from previous HDB SBF launches|
|How many units||Around 3,000||Depends, but typically less than 100|
|Unit mix||Most unit types available||Limited unit sizes|
|Locations||Mature & non-mature estates||Mature & non-mature estates, but only a few in each|
|Ethnic quota||Fairly spread out among races||Very few units for Chinese buyers|
Do note that since these are, like I mentioned, the balance flats of the balance flats, they are NOT for fussies.
If you are super duper particular about being on the top floor or the fengshui of your unit, then it goes without saying that you should probably give this a miss. Instead, these balance flats were meant for those in more pressing need of housing, and don’t mind taking a look at what’s available as long as they can get their keys ASAP.
However, from my personal experience, there are some pretty great units at HDB SBF launches. Many couples default on their super hyped $400k or $500k high floor units after realising that they can’t pay up for the hefty down payments, can’t get sufficient mortgage to cover their flat’s price, or umm… broke up.
I got a 23rd floor leftover BTO unit near Clementi MRT in an SBF exercise years ago. And you can actually spend a weekend going around to “view” the units available on the SBF list, create a top 5/ top 10 list, before going to HDB on your appointment day to choose.
The greatest advantage is that the waiting time for open booking flats is way shorter than both SBF and BTO. If successful, you can get invited to HDB to select your flat as early as the next working day of your application! That’s crazy efficient.
Plus, since they are farther along in the HDB BTO timeline, you can expect a much shorter wait for these balance flats to be built. Some might even be available to move into already.
4. What are Sale of Balance Flats (SBF) launches like?
HDB SBF launches happen twice a year, typically in May and November, and coincide with HDB BTO launches. You have to choose either the BTO or SBF route — applying for both during the same launch is not allowed.
You can take a look at the previous HDB Sale of Balance Flats launch in Nov 2021 for an idea of the number of units and flat mix.
One thing that makes HDB Sale of Balance Flats very different from applying for a BTO is the sheer variety and depth of information provided.
With HDB BTOs, it’s a leap of faith. All you really need to do is to choose your preferred location and flat size. HDB provides just the generic map, so you just have to hope that it’ll live up to your expectations.
But with the SBF, HDB provides a ton of information, right down to the block number (so you know exactly where it is), unit number (so you know which floor it’s on), and the ethnic quota (so you know whether you got chance or not).
Plus each batch has some 3,000 units across virtually all flat types and locations, which can really send you into decision paralysis.
Fortunately, each SBF launch is about a week long, so you and your partner/family can take your time (sorta) to carefully review the information available and make your choice. You can only choose one location and one flat type, so please weigh all the factors (especially flat supply!) carefully.
As for the flat itself? Well, it’s the same as the other BTO flats in your block lah, although possibly on a low floor or facing West or some other factor deemed as “dealbreaker” by a picky buyer. To take a case study, my colleague bought a low floor flat in Punggol through an SBF exercise, and the wait was only one year.
5. How to apply for Sale of Balance Flats (SBF)?
We’ve talked about how the time frame for HDB SBF is the same as that of BTOs — and whaddyaknow? It turns out that application procedure is similar as well.
Step 1: Check eligibility. The eligibility criteria, income ceiling, and housing schemes that apply to BTOs also apply to Sale of Balance Flats. For a recap of the criteria, see our step-by-step guide to applying for a BTO or HDB’s official eligibility page.
Step 2: Apply for your flat. Hopefully you have digested all the information available on HDB’s SBF page and made your decision. If so, you may submit a simple online application on the sales launch page, and pay a $10 admin fee. This needs to be done within the 1-week window that HDB usually gives for their BTO/SBF launches.
Step 3: Wait for results. After application closes, prepare to spend the next few weeks in an insomniac state as HDB conducts the balloting process. This is basically a lottery, but HDB has set it up in such a way that your chances are better if you are a first-time applicant, applying as a couple or family. If eligible for one of the HDB priority schemes (e.g. for living near your parents), you can improve your chances.
Step 4: Get your home loan in order. Meanwhile, you’ll want to prepare for a home loan since you’ll need one to secure your flat. If you’re planning to get an HDB loan, you need to apply for an HLE (HDB Loan Eligibility) letter. For a bank loan, you’ll have to ask for an AIP (Approval in Principle) letter from the bank.
Step 5: Hear from HDB. At the end of about 3 weeks, you’ll get a letter from HDB with your ballot queue number. If it’s something ridiculous like #1,735 then GG lah, better luck next time. But if your queue number is reasonably small, you get an appointment with HDB for the event of the year: Your SBF flat selection. *pops champagne*
Step 6: Go to HDB and book your flat. At HDB Hub, you’ll be shown what’s available to you, and, if you like what you see, you can book it on the spot (must pay an option fee of $500, $1,000 or $2,000, depending on the size of your flat). Once you have your finances in order, you can come back and sign the official lease agreement and make the downpayment of 20% (HDB loan) or 25% (bank loan) of the flat price.
While you’re at HDB Hub, do head upstairs to the “MyNiceHome Gallery” to check out the 2-room, 3-room, 4-room, and 5-room new BTO flat layouts and mentally prepare yourself to stay in a teeny weeny house.
Step 7: Key collection. Assuming all goes well, the next time you’ll hear from HDB is when your key is ready. Hurray! Depending on how far along your flat is in the construction process, key collection day can be as early as within 3 months (if it’s already complete) to 2+ years (if it’s a previously-unsold BTO).
6. How to apply for HDB Open Booking flats?
HDB Open Booking was designed to be available all year round, so there was no need to wait till HDB launches a BTO to apply for one or go through the whole balloting process.
It was meant to be first come, first served. You could do it anytime, provided you can find one that you qualify for and suits you.
At time of writing, Open Booking was last open temporarily from 23 March 2022. The next Open Booking will open for applications on 12 October 2022.
If you qualify, you’ll be very pleased to know that the HDB open booking is short and simple.
Step 1: Check your eligibility. As with all flats bought directly from HDB, you need to meet certain age/family/income requirements, so check your eligibility here before applying.
Step 2: Settle your loan. At the same time, you should also obtain an HDB Loan Eligibility letter or loan Approval in Principal letter from your bank. Things move at lighting speed with ROF, so you should prepare all the admin ahead of application.
Step 3: Apply for your flat. No need to wait around for an auspicious date, because balance units are first come, first served. This means that if you see anything you like and have fulfilled all the eligibility requirements, you should apply online immediately. The usual $10 admin fee applies.
Step 4: Get an appointment with HDB. Immediately after application, you’ll receive a queue number and an appointment to book your flat. This can be as early as the same day of your application (if you book before noon on a weekday — otherwise, it’s the next working day). So it’s best to clear your schedule on application day!
Step 5: Book your flat. During your appointment with HDB, you can go ahead and book the flat by paying a $500, $1,000 or $2,000 option fee (depending on flat size). If opting for HDB loan, you also need to submit your HLE letter while booking
Step 6: Sign lease agreement. The next HDB appointment is to sign the official agreement. You will want to make sure you have enough cash/CPF on this day, because it’s also when you’ll be making the downpayment (20% or 25% of your flat), plus legal and stamp fees (1% to 3% of the flat).
Step 7: Key collection. If the flat you booked is already complete, you can collect your keys on the same day as signing the lease agreement. Talk about efficient! Otherwise, you will need to wait till the block is constructed and then collect your key.
7. I don’t have enough money for my BTO or SBF
With an HDB BTO, you have what seems like all the time in the world to save up for your downpayment and sort out your finances.
But due to the chop-chop nature of HDB SBF and ROF, some applicants may run into cashflow issues. To help with that, HDB has a few concessions.
Deferment of HLE: For HDB ROF, if you’re fresh out of school or NS (within 12 months), you don’t need to submit your HLE when booking your flat. You can defer your income assessment until 3 months before key collection — HDB will notify you to submit your income documents then.
Staggered Downpayment Scheme: First-timer couple applicants under 30 years old, or current homeowners looking to downsize to a smaller flat, can request for the downpayment to be paid in 2 parts. Assuming you go for an HDB loan, this means you only need to pay 10% when you sign the lease agreement, and the other 10% at key collection.
(HDB Loan downpayment used to be 10%, then it was increased to 15% in Dec 2021, and subsequently 20% from 30 Sep 2022 onwards).
Deferred Downpayment Scheme: For elderly (age 55 and up) homeowners looking to downsize their current flat to a smaller home, your downpayment due date will be automatically extended until key collection date. When signing the lease agreement, you will only need to pay the stamp duty and legal fees (1% to 3% of flat).
Temporary Loan Scheme: If you’re in the midst of selling your current flat and want to use the proceeds to pay for your new flat, this scheme allows you to get a short-term loan from HDB to help with the cashflow while you wait for the sale proceeds to come in.
8. HDB Loan or Bank Loan for my BTO or SBF?
No matter how long you put off financing your HDB flat, you’ll have to deal with the painful money bit of buying your flat at some point.
Like every other home buyer, you’ll need to decide on who you get your home loan from — whether it’s HDB or a bank.
Requiring no cash downpayment, the HDB loan is the default choice for many new homeowners. However, if you have enough cash for the downpayment, bank loans typically have lower interest rates.
