Is it possible to refinance from HDB to bank loan without topping up cash?

Apparently the amount the bank will lend you is based on the bank's own valuation of your property. So, 75% of the bank's valuation may not be the same as 75% of your original HDB valuation. It could be more, it could be less. I was told that the paydown can be made with CPF or cash. So, depending on your liquidity, CPF may be an option... (although, you would need to do your math if it's worth missing out on the 2.5% interest if you kept it sitting in your OA). I'm no expert as I'm also in the midst of exploring options to refinance my own HDB loan too. Just sharing what I've found out so far. Good luck! ​​​
