Is it better to sell HDB and buy another house or sell HDB and rent a house now?

Depends on how much you want to earn and what you need the money for? Short or long term goals?

Generally your own house shouldn’t be considered as an investment or smth you profit from since it’s something you need. Your needs should always take the first priority!

However, you can choose to sell and rent as that would give you cash at hand assuming you don’t payback CPF. Which you could then invest it else where. Cash is King always!

Or you can just rent out your current house now for a higher price as compared to the rent you pay for another house to stay in. Then that way you’ll have additional cash flow every month. But this is risky if you can’t find people to rent to.

Ultimately your goals will decide which is the best option for your family
