Application rate for last 1 year of BTO projects and SBF launches, breakdown by flat type, can be seen in HDB InfoWeb Appliation Status (outdated link, can someone give me link where I can see application rates for Aug 2021 onward?)
I saved every page in HTML format in my computer (since 2010 to present), also compiled an Excel table with a summary of application rate per BTO and SBF launch. Updated after May 2021 BTO+SBF.
Detailed application rates per BTO and flat type are available in HTML pages, I did not compiled them (yet) into Excel because table format vary from one BTO to other and I don’t know what would be optimal table format. Any suggestions?
Don’t forget to check other databases made by me (100+ databases).
Until October 2015 site redesign, the application rate for past BTO far back as Aug 2010 was still accessible via direct links (http://services2.hdb.gov.sg/webapp/BP13BTOENQWeb/BP13J011BTOAug10.jsp) although no longer visible in the Application Status page. I saved the pages so you can download HTML files from me.
An application rate 3.00 means that number of applications exceed 3 times flat supply, theoretically 1 of 3 people will be invited to select a flat. An application rate 1.00 does not always mean that everyone got a flat, because some flat types gets oversubscribed while others undersubscribed.
For example, the May 2013 BTO set a new record of low applicant rate: 1.07 overall, this does not mean that everyone got a home. The 4-room units got 4.3 in Hougang BTO while in Sembawang BTO the rate was 0.4 (60% flats remained unsold). Stupid idea to launch BTO in such bad location in the same time with SBF, obviously people went in SBF for better located flats.
In May 2015 for the first time HDB announced the launch date 1 week before the actual launch, the application rate being unusual high even after one day of sales, proving that HDB is still undersupply. Surprisingly, first time BTO exceeded SBF application rate.
