Hi, I am just making an enquiry here. I am currently 35 years old and I am thinking of buying a 4 room resale flat under the singles scheme. Currently, I co-own a 5 room flat with my parents and my brother. My question is this. If I buy a 4 room resale flat and my name and my CPF for that matter is removed from the 5 room flat that I currently co-own, it is most likely that HDB will have to recalculate the existing HDB loan/interest rate for 5 room flat. Actually, I intend to move my parents over to stay with me and sublet the entire 5 room flat to make some income and also to service the HDB loan. The catch is this, my parents and my brother have irregular income. Any chances that this will work out? Thanks in advance for your expert opinion and comment.
