UK Landlord Forum / Life

Hello, I have a propertry I purchased in July 2006,  I lived in this propertry until end of March 2018. There is no mortgage on the propertry which is rented out. I live abroad so am classed as a non resident landlord. I have a couple of questions
1. If I decide to move back to this propertry in the next few years, how long do I have to live there to avoid paying CGT?
2. How will the new tax laws affect me when they come in to force in April 2020 if I decide to sell the propertry after this date?


If you need further information to answer my question, please let me know.
Thanks so much.
