What is HDB Open Booking of Flats?
These are unallocated flats that are consolidated from previous BTO Exercises and Sale of Balance Flats Exercises. It also includes completed flats that are repossessed or bought back by HDB. These flats are subject to the usual eligibility requirements such as ethnic quota, income ceilings and housing schemes.
The queue system is on a first come first serve basis, so you can get a confirmation on your flat really fast and you can also choose from flats that are already completed (subject to availability of course).
While these flats may not be your ideal first choice units, but it does give you a roof under your head and you might even discover a gem amongst it all.
