HDB BTO application guide: ballots, ceilings and flat types

Build-To-Order (BTO) projects are sold in launches a few times a year. You apply online during the window, and projects with more demand than units are allocated by a computer ballot.

Ballot position

Your queue number decides which flat you can pick. Family priority schemes, first-time buyer status and parenthood quotas all affect your odds, so apply under the scheme you genuinely qualify for.

Choosing a flat type

2-room Flexi suits smaller households and buyers who want a lower price. 4-room is the most common choice for couples with children, and 5-room gives the most room for the same lease terms.

After you get the letter

You will be asked to attend a flat selection appointment, sign the lease agreement, and then wait for completion. Budget for stamp duty, legal fees, and the deposit for the flat you selected.
