HDB SBF & ROF — Complete Guide to Applying for Sale of Balance Flats

hdb sales of balance flat

Although the SOP for buying an HDB BTO flat has been well-documented, buying a balance flat via HDB’s Sale of Balance Flats (HDB SBF) or the new open booking system is a little less talked-about.

If you haven’t already heard, as of 4 Mar 2020, the Housing Board announced that they will scrap the Re-offer of Balance Flats (ROF) exercises. Don’t panic though, the balance flats will still be available all year round, so it’s not like you have to wait for the next launch.

The only change is that instead of the HDB ROF exercise, the unsold units from the HDB SBF exercise will be put up for open booking instead.


First of all, what on earth is a “Balance Flat”?

As alluded above, the main advantage that buying a balance flat gives is the chance to jump the [BTO] queue.

HDB BTOs are launched only a few times a year, and they may not be located in the estate you want. For example, the BTO launches for 2019 are in Punggol, Tampines, Tengah, Ang Mo Kio and Tampines. Tough luck if you’re hoping for a place near your parents in Clementi.

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.

Finally, after you manage to secure a BTO flat, there’s still a long-ass wait of at least 3 to 4 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 Balance Flat 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)
  • 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
  • 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


Sale of Balance Flats (SBF) vs Re-offer of Balance Flats (ROF) vs Open Booking of Flats

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 another flat).

Prior to the announcement on 4 Mar 2020, there was also the HDB Re-offer of Balance Flats (ROF) exercise, but that’s no longer available. Those were the flats left over from the previous HDB SBF exercises… Again, they either had no takers among the successful SBF applicants, or they were selected but later given up.

So without the HDB ROF exercise, what would become of the leftover, leftover flats? Well, they will still be available for purchase, except now, they will be offered for open booking.

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) Open booking throughout the year
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 are 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.

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.


What are HDB Sale of Balance Flats (SBF) like?

HDB SBF launches happen twice a year, typically in May and November. They coincide with HDB BTO launches. (Unfortunately, you have to choose either the BTO or SBF route — applying for both during the same launch is not allowed!)

The last HDB Sale of Balance Flats Launch was in November last year. There were 3,599 flats in that round, in places like Sengkang, Yishun, Bedok, Clementi and Tampines. next Sale of Balance Flats Launch has not yet been announced, but will likely be in May 2020.

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.


How do you apply for HDB 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 10% (HDB loan) or 20% (bank loan) of the flat price.

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).


How do you apply for HDB Open Booking of Flats?

HDB Open Booking is available all year round, so there is no need to wait till HDB launches a BTO to apply for one or go through the whole balloting process. It’s simply first come, first served — all available units will be open for booking from 18 Mar 2020 onwards. 

You can do it anytime, provided you can find one that you qualify for and suits you. Be warned: There aren’t a whole lot of options with this one!

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 HDB ROF 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 (10% or 20% 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.


What if you run into cashflow problems?

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 halves. Assuming you go for an HDB loan, this means you only need to pay 5% when you sign the lease agreement, and the other 5% at key collection.

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.
