I am selling my previous primary residence which I bought in Sept 2001 and moved out in Sept 2011 . Since then I put that one for rent . Now selling that property . Two questions - Since I am selling within 3 years after moving out am I liable for Capital Gains Tax ? Secondly with the sale , after paying the mortgage , the remaining amount do I have to put in my current mortgage ( which is now my primary residence) to avoid capital gains tax ? or can I use that money for something else. Your suggestions much appreciated.
