I know this has probably been done before but I am getting conflicting advise. I bought a house 11 years ago for £14700, it was paid cash. MIL has stayed in it rent free all that time, I have never lived in it. It is now worth around £100,000. I would like to sell it soon and buy another property but from what I can gather I will have to pay so much in CGT that I won't be able to afford to buy another. About £13000 paid to upgrade, (not by me) and I am retired on a state pension, just started in business but not earned much yet. Does anyone know what I would be due CGT? Thanks.
