I stay in a resales HDB 5 rooms for 10 years, i believe it already meets the MOP. I am interested to buy a condos to stay and keep my HDB flat for my parents to stay. There are still some outstanding loan for my HDB flat, am I allow to buy a condo if i have not clear the HDB loan (about 100K)? What will be the min cash value for a 850K condo? Can I use part of my CPF to pay for the monthly loan for the condos as my current loan only use less than 50% of the cpf max cap for housing ? I have about 100K in my cpf, can I use this fund for the condo ? Thank you.
