I am a single lady of over 64. I have one commercial property in International Plaza, which is my monthly income. I am a Singapore citizen & currently I am renting an HDB flat. I would like to buy a 2 bedroom HDB. Can I do that considering I have a commercial property ? What is the procedure of buying one & how long will it take , before I can buy a new HDB ? My income is about $3000/ thank you.
