Our BTO Journey – Part 3: Flat Selection

This is the third part of “Our BTO Journey” series where I intend to share my complete journey buying a BTO flat.


Part 1: Why BTO?
Part 2: Application and Balloting
Part 3: Flat Selection
Part 4: EHG, Signing of Lease, Downpayment

In my previous article, I wrote that I got the balloting result of Feb 2021 BTO in March 2021. The email from HDB mentioned that selection would start in April 2021.


Receiving Appointment Date

After waiting in vain for the entire April, finally the long-awaited sms & email from HDB came in early May, telling us that we are invited to book a flat 2 weeks later.

After receiving the sms & email, we logged in to HDB website to download the appointment letter. This is what we see in HDB portal.

BTO unit selection - 2. flat selection details

Inside the appointment letter, there are instructions on things to do before attending the first appointment as well as forms to print out, fill in, sign and submit on the day of appointment. Listing is a list of every unit and its corresponding price in this specific BTO project.

Information Leaflet is just a general information on OCS, how to use HDB portal, HLE, etc. Meanwhile, the sales brochure has information on site plan, unit plan, unit distribution matrix for each block, floor plans of every block, general specifications (eg: door types, wall finishes, etc) and details on Optional Component Scheme (OCS).

On the same page as the above section, when you scroll up/down, there is a section where you can know what’s the last queue number invited for selection of that particular day when you access the portal. Only people who have received appointment date but have yet to attend the appointment get to see this section. It looks like the below image.

Decision Time: Nov 20 vs Feb 21

Because we received invitation for Feb 21 selection first, we had to make decision whether to go for Feb 21 BTO or not. At that time, Nov 20 was still in the midst of selection and we hadn’t received any invitation for Nov 20 yet. We were not sure whether there will still be units available when our turn came for Nov 20, and we did not want to take the risk.

We decided to go for the Feb 21 BTO. Another reason we chose Feb 21 was because our number was low 2-digit, so we had a good chance of getting a very good unit, and even a chance to get a unit at the topmost level.

Applying for HLE

If you’re taking HDB Loan, you need to get HLE (HDB Loan Eligibility) Letter before attending the first appointment for unit selection. We’re taking HDB Loan to save on downpayment (HDB Loan only needs 10% downpayment while bank loan needs 25% downpayment), so we need to submit application for HLE.

Applying for HLE is pretty easy and straightforward. You just need to prepare the necessary income documents in softcopy, then apply online and upload your documents. After submission, if HDB need more documents, they will inform you via sms.

While most people apply HLE after getting an appointment date, we were quite kiasu. We applied even before we knew we were successful in the balloting. That’s because we were afraid that HLE application may take weeks. The truth is, our HLE was approved in 6 calendar days.

We applied for HLE in late February 2021. 2 days after we submitted the application, we received sms saying that more documents were needed. So we uploaded the additional documents on that same day. Then, 4 days later, we received sms informing us on the approval.

Prepare documents

In the appointment letter, there is a list of documents in the Annex 1 that you need to prepare and bring to the appointment (basically it’s quite similar to this list on HDB website). The Annex 1 for everyone is different, depending on their employment type, HDB scheme, their grant eligibility, etc etc.

In addition, there are also forms that you need to fill and sign and submit to HDB officer during appointment (it’s better to fill them in advance before appointment).

The Annex 1 list in our appointment letter didn’t ask for marriage cert, but the list on HDB website includes marriage cert. To be safe, we bought our marriage cert during appointment. The HDB officer did ask for our marriage cert during the appointment, fortunately we brought it.

Submit EHG documents online

In the appointment letter – EHG section, there is a paragraph that says we can submit our documents online (before appointment) for their preliminary assessment.

BTO unit selection - 5. Submit EHG online

Being the typical kiasu couple, we submitted our documents online before the deadline because we want to quickly know how much grant we can get.

From our conversation with our neighbours in the same project, some of them didn’t submit online and they receive grant approval around the same time as us. So, I guess there’s no guarantee that submitting online will lead to quicker result. But we still wouldn’t change a thing even if we could go back in time.


Site Visit

With documents preparation done, it’s time to prepare a list of unit that we want. We have the site plan in the brochure, and we can view the 3D model from HDB website, but something is missing. Seeing the softcopy is not enough, we need to know how it feels to stay in units facing certain direction. Hence, we decided to visit the site so that we can gauge which unit will have blocked view, and which unit will have unblocked view.


To be honest, we can’t really create a shortlist until the day before our appointment. That’s because every time we shortlist a unit, it gets taken by people in front of our q number.

The day before our appointment was one of the toughest days in this BTO journey. We knew that we would be the 4th-in-line on our appointment day (because the last Q on the day before our appt is 4 number in front of us), so we needed to shortlist 4 units in case the 3 group in front of us select the units in our list.

After much deliberation, we could only come up with 3 units, and we still couldn’t agree unanimously on the sequence of our shortlisted units. We keep going back and forth between the unit that face park (but not topmost level), the unit at the topmost level that face other block (but can get a glimpse of the park), the unit at the topmost level facing other project with similar height which is quite far away (but will get afternoon sun). Sigh! I guess the perfect unit doesn’t exist.


On the day of Selection (BTO 1st Appointment)

On the appointment day, we were only allowed to enter HDB 30 minutes before our appointment time. During the 30 minutes, we were allowed to look at the sample of OCS as well as the 3D model.

While other couples sit quietly at the waiting bench, we spent 5 mins looking at OCS and 25 mins thoroughly examining the 3D models. We stood on our tiptoes, half squatted, while taking photos and videos of the model, trying to imagine what our view would be in the units that we shortlisted.

One of the units in our shortlist was taken before our turn (the one that face the park), so we were left with 2 choices. One is my favorite (topmost, face other project that’s far away but west sun), and one is my spouse’s favorite (topmost, glimpse of park, facing other block that’s very near to the unit). After our thorough examination of the 3D model, both of us still hate each other’s favorite. I hate having blocked view, and my spouse hates afternoon sun.

Then our number appeared on the screen. It’s time to choose!


We walked to our designated desk. The HDB officer asked us which unit we want. We asked her for advice, but she declined to give any advice. We spent the next 5 mins discussing with each other, while HDB officer awkwardly waited for our decision. Realising that we were wasting her time, I quickly passed the documents to her to check first, while we continued to discuss on which unit to take.

After what felt like forever, we finally made the decision to go with a unit that’s neither my favorite nor my spouse’s favorite; it doesn’t have blocked view and afternoon sun (yay) but it’s not the topmost level. I believe that’s the best solution. I’m glad we survived the tough task of choosing our future home.

Next, it’s time to sign more papers and make payment of the booking fee/option fee ($2,000). There’s only 1 acceptable method to pay the $2k: by Nets.

The HDB officer asked me to provide additional documents that’s not listed in the list. Because I did not bring it on that day, she asked me to submit the document online.

The officer also explained to us the timeline for payment, and the estimate amount of money that we need to prepare to pay downpayment on the second appointment, in approximately 4 months time.


Wait for Result of EHG and 2nd Appointment

The next step is patiently wait for the result of EHG and the schedule of 2nd appointment (downpayment and signing of lease).

Even though the officer said that 2nd appt will be in approx 4 months time, but we noticed the Option to Purchase (OTP) that we signed is valid for 9 months, so technically it is possible that our second appointment could be postponed to 9 months after unit selection. Oh well.

While waiting, I guess it’s a good time to think about whether we want to pay the downpayment with CPF or cash. On one hand, we do not like the idea of accrued interest that keeps increasing every year. On the other hand, we also want cash liquidity.

We decided that we will pay the downpayment (minus grant) with CPF first. Then, we will slowly pay back CPF to reduce accrued interest.

Everyone has their own preference on whether to use CPF for housing or not. For me, I prefer not to use CPF for housing. I know it’s an unpopular opinion but I have my own reason. I’m planning to write about this topic in the future.


Next post is about EHG, signing of lease and making downpayment. Stay tuned!

    Hello. Single person here applying for the past 2 BTO launches without success. I just finished applying for the Oct launch and saw a comment on my application page: Last BTO queue number invited to book a 2 room-Flexi xxx estate but without the queue number. Would appreciate if you can advise what this means. Any input or feedback will be appreciated.

    Hello! I was just wondering if by any chance, you would know if we are able to reschedule our flat selection appointment date? We are worried that it might clash with our exam dates. Thank you!

    May i know what other supporting documents they required?

    1. prudentdreamer

      Hi Miao Lim, everyone will need to provide different supporting documents, depending on their circumstances. I can’t recall what my supporting documents were, because it’s more than a year already. If I have to guess, it’s probably my ACRA biz profile.

    Hi, Thanks for sharing 🙂
    May I ask how did you know which unit is already taken?
    Is there any special page available for the applicants once the selection activity starts?

    From your experience, do we need to get very front numbers to get the top floor? I was thinking that it is the most tempting floor to people right?

    1. prudentdreamer

      Hi Zeon,
      Yes, there’s a special page to see which unit has been taken, just go to homes.hdb.gov.sg and login via Singpass, then go to “My Profile” and you’ll see the project that you got a ballot number for. Click on it and you’ll see which units have already been taken.
      From my own observation, if the number units available at topmost floor for 5-room is 20 units for example, those with ballot number 40 (2x the available unit) and below has a real chance of getting the topmost level, cos not everyone wants to get the topmost level, some may prefer certain facing and decide not to get topmost level in favor of their preferred facing. Good luck!

    The part on choosing both your favorite flat was quite funny ><. Just to check, I thought we have to use up all our CPF with option to leave up to 20k?

    1. prudentdreamer

      Hi Cat, you’re right, if taking HDB Housing Loan, we need to use up CPF OA or leave 20k inside. I didn’t really explore whether one can choose to pay downpayment via cash or not. Anyway, if HDB doesn’t allow cash payment if there are sufficient CPF, but you want to pay by cash, you can always pay by CPF first, then top up CPF through “Make Housing Refund” on CPF’s website.

    Hi, so did you go with the NOV 2020 BTO queue number for flat selection or FEB 2021 queue number?

    1. prudentdreamer

      I went with Feb 21 BTO cos the invitation to book flat came first from Feb 21 BTO. Also, my q number in Feb 21 is better than Nov 20.

      1. Amy

        hi! i’ve read your blog and truly appreciate the informative chunk that you shared regarding your BTO process!! I just got my ballot number too but its not within the range of units, exactly like your NOV 20 situation. It states that I may get a selection, but there is also an opening in FEB 22, does that mean if i apply for FEB 22, it will forfeit my ballot number for NOV 21?

        1. prudentdreamer

          Hi Amy, congrats for getting a q number for Nov 21! No, you won’t forfeit your number for Nov 21 if you apply for Feb 22. I’d recommend that you just apply for Feb 22 as well, and then evaluate which one you will go for. Most likely, you will get a chance to choose unit for Nov 21, but it will be all lower floors. If you also get a number for Feb 22, you just see which project invite you first and which one you like more. If Nov 21 invite you first, but your number for Feb 22 is better and you like Feb 22 more, then you just don’t attend the appointment for Nov 21 (this also means you reject 1x, each person can only reject 2x before they are suspended from first-timer priority for 1 year). Hope it helps!
