Hello, I am a solicitor with 20 years experience. i will try to help you with this. Yes it sounds like you will have to pay CGT on the profit you make on the sale. This will be charged at either 18 or 28% depending on your situation but it sounds like to will be 18% from what you say. Gains for the period you lived in the property will be exempt as will. If you have lived in it since 1982 this will be true and various other reliefs and exemptions may apply. It is not possible to calculate your likely tax bill on the Just answer service and it is something that your conveyancing solicitor should be advising you about.
