Hi Peter, as mentioned by the rest that you are allowed to keep your HDB and purchase the condo provided that MOP is fulfilled, there are 2 other factors that you need to know. 1) if your current HDB is not fully paid, the maximum amount that the bank is willing to loan you is only 50% of the valuation of the next property. What is means is that for 800k property, you would need to have at least 400k cash/cpf. If you include the ABSD/BSD, it could be a stretch for most upgraders. Do give me a call @ 81613790 or email me: email@example.com if you would like to find out more on the financial planning to your next home purchase.
