How does the process for HDB loan repayment work between the paying parties work? Do we have the flexibility to change the amount paid based on % or absolute amounts as and when needed?

Hello! I'm assuming you're using the HDB loan your flat.

if I'm not wrong, you can change the allocation amount at any time you wish.

According to the CPF website, in order to do that:

1. Bring along your identity card to the HDB branch office which is managing your flat.

2. Complete the 'Application for withdrawal under Public Housing Schemes' (HPS/9).

3. HDB will forward the completed form to the Board for processing.

Hope this helps! :-)
