History of Sale of Balance Flats

Sale of Balance Flats, comprising unsold leftover flats from past BTO launches, surplus flats from SERS projects, old repurchased flats (including flats from some divorced or fiance couples), are done “when HDB accumulate sufficient flats“, usually twice per year, but this is NOT A RULE. Since 2010 the SBF exercise is done same day with a BTO launch.

In May 2015 HDB announced that have 9,000 unsold flats that will be offered in two SBF exercises concurrent with May and August BTO launches, but in press release of 1 July 2015 HDB announced that the exercise was delayed to September, then the BTO launch was cancelled and mixed up with November BTO launch, and SBF was done at same time. Reason: HDB needed extra time to implement the new schemes of 2-Room Flexi and grants.

Fiance-fiancee couples who break up and do not get married within 6 months after receiving keys, as well as other people who for whatever reason need to sell the flat back to HDB during minimum occupation period, need to pay a penalty of 5% of market value of the flat, but more severely, they lose the first-timer status, and the flat is sold again via Sale of Balance Flats.

SBF brochures

I visted HDB InfoWeb for first time in late 2008 and saved only SBF brochures, being interested in floor plans of individual units. Since early 2010 I started saving every BTO brochure too, so earliest BTO brochures I was able to find were December 2009 ones.

If you are looking for older BTO, you can try your luck below, if the block had leftover / unsold flats you may find block floor plans below (these SBF brochures also contain floor plans of individual flats, repurchased by HDB).

2012-onward SBF brochures I can provide on request basis for some $, because HDB no longer provide one brochure for each town, they provide instead separate files for each site plan, each block plan, each individual flat available for sale, making a total of over 1000 PDF and JPG files for each sale launch, had to spend 10-15 hours right clicking > save file as, until 2016 when I started feeling that I am wasting time downloading brochures for too little benefits.

  1. Hi Teoalida,

    I’m currently in a queue to purchase a 5room or executive unit in Bedok at these two locations:

    1) 634 Bedok Reservoir Rd, Block 634, Singapore 410634 Unit 02-09

    2) Blk 669 Jalan Damai, Singapore 410669 #12-59

    I would appreciate a rough guide for their floor plans as I’ve already visited the locations but can’t seem to fathom how they will look like inside.


    1. 634 = a block 4 different layouts of EA, see floorplans in
      669 = a block with 4-room and 5-room, floorplans posted just above the EA one, most likely the 5-room is like this
      telling me unit number is useless because can’t know on which side of block your unit is
      if you applied via SBF you should wait until application results are finalized as they will publish exact floorplans… rather than asking people online to give you possible floor plans.

  2. Hi,

    I am looking for floor plans of a 5-Rm HDB 122 sqm Block 224 Choa Chu Kang Central.

    Your help is greatly appreciated! Thank you.

  3. I would like to know if the warmness of tiles on one floor of a unit could be affected in any way by the wiring of the ceiling in the unit below it?
    Is this possible in a condo?

    Is there any gap in the flooring of one unit and the ceiling of the one below it?

    1. Why are you asking same thing over and over again, after I answered you?
