When I first got my flat, there is no 20K buffer arrangement, I wipe out my OA. I didn't keep a buffer of several thousands by investing it away, maybe because I am confident of the security of my job.

My first decision in on the allocation of payment of OA to our mortgage. I wipe out my OA monthly contribution and my wife pay the balance. The rationale is my wife can stop working temporarily if she is pregnant or if she needs to take care of kids.

When the HDB officer mention there insurance payable etc, I smile and say there is bonus which will increase CPF contribution monthly too.

My first working decade, especially the first 5 years, my CPF account is a joke. It never really grow, I kinda of even secretly blame myself and wife for this arrangement.

I had plenty of people asking me ...
