HDB Resale Flat Prices Database

Database of HDB resale flat prices in Excel format

On 1 April 2009, HDB improved its Resale Flat Prices e-service, now showing transactions for last 1 year instead of last 3 months, also added flat model beside floor area. I copied the listings for 1 year (April 2008 – March 2009) in Microsoft Excel, which were displaying 20 per page. I spent about 10 days at 5 hours per day. I did this for purpose of personal analysis, for example estimate average apartment size nationwide and per town, and showing the results of analysis in HDB Statistics page. Few months later HDB showed all transactions in a scroll-able list rather than 20 pages, allowing me to copy transactions much faster, so started to update my database once per year.

Is possible (and legal) to obtain a mobile phone numbers database?

Homeowners associations does have phone numbers of some owners (is a good practice to give your contact info to be announced in case there is a problem in your home while you are away), car insurance companies also have phone numbers of their clients, but what makes you to think that they would give their database to you or potential competitors? Also, distributing / selling phone numbers without owner consent is ILLEGAL all over the world. In Singapore you can be fined up to $10,000 or up to 12 months of jail according
