You will be able to explain how a BTO flat is priced, how long you wait and what the minimum occupation period locks you into.
A Build-To-Order (BTO) flat is sold by HDB before it is built. You apply during a sales launch, receive a queue number by ballot, choose a unit if your number comes up, then wait for the building to be finished. HDB sets the price at launch. Unlike a resale purchase, you are not bidding against other buyers on the day, and the price does not move while you wait.
That waiting period is the first cost most buyers underprice. From the day you book to the day you collect your keys, you still need somewhere to live. For many couples that means renting or staying with family for years. HDB publishes an estimated completion date for each project, and it is worth writing that date down before you apply, because every plan you make for those years depends on it. A resale flat, by contrast, can be yours within months of agreeing a price.
The second cost is the lock. Every HDB flat comes with a minimum occupation period (MOP): a stretch of years you must live in the flat before you can sell it on the open market, rent out the whole flat or buy a private property. The clock does not start when you apply. It starts when you collect your keys. So the real time from application to the first day you could sell is the building time plus the MOP.
Work it through with example figures. Suppose your flat takes four years to build and its MOP is five years. You apply at 28, collect your keys at 32 and can first sell at 37. If you expect a job move, a growing family or a parent who may need care in that time, the flat has to fit all of it, because selling early is not allowed except in narrow cases HDB approves.
The length of the MOP and the other conditions depend on the flat. HDB now classifies new flats into different categories, and some carry a longer MOP and stricter resale conditions in return for a lower price or a better location. These rules have changed several times, and they may change again. Check the conditions for the exact launch on the HDB website before you apply, and read them again before you book a unit.
None of this makes a BTO a bad choice. The price is set by HDB rather than by the market, grants can lower it further, and a new flat starts with a full lease. Many owners in popular towns sell well after the MOP ends, because buyers will pay for a newer flat with plenty of lease left. But any gain is only available once the MOP clears. Until then, the money you put in is tied to that flat, and any CPF you use is building up accrued interest that must be refunded to your CPF account when you sell. Module 8 shows how that refund comes out of the sale proceeds before you receive any cash.
So the honest comparison between a BTO and a resale flat is not price against price. It is price, plus the cost of waiting, plus the years you are locked in, against a higher price that you can move into sooner and that comes with a shorter lease. Lesson 1.2 looks at the resale side, and lesson 1.5 puts both into one sheet over ten years.
For now, pick one BTO launch you would realistically apply for. Write down its estimated price, the town and flat type, its estimated completion date, the MOP that applies to it, and the year you would actually be free to sell. You will carry those figures into the comparison at the end of this module.
