Just done our papers and collected our keys for our BTO flat this week. Here's our findings:

1. CPF will be wiped out 2 weeks later after key collection

2. Loan period starts on your key collection date

3. But your first CPF deduction will only commence 2 months later (means more interest to pay since principle amount remains undeducted for 2 months). I think CPF is trying to build create some buffer such that the CPF OA account has some money 2 months later after the wipe out.

4. If one wants to do a partial captial repayment (means to pay off some of your HDB debt in addition to your regular loan repayments to cut down on the total interest incurred), the minimum amount is $5000 and I had just learnt from the HDB website that the date will be one month later upon your application.

Hope this helps and wish all of you who are taking part in the year 2016's last launch of 10 000 BTO flats and Sales of Balance flat the best of luck!
