I currently rent the flat I live in. I intend on moving into a property I own but have been renting to tenants (through an agency). If after two or three years or so I then decide to sell the property and move back to a rented flat will I have to pay capital gains tax?

Arthur Weller replies:
Since you own this property and will have lived in it for two or three years you will be eligible to partial principal private residence (PPR) relief from capital gains tax, based on the proportion of the time you lived in it as your PPR, to the amount of time you owned the property. If the time that you lived in it as your PPR was (say) half the time you owned it, half the gain will be exempt from tax (note that after April 2020, the rules for the PPR lettings exemption will change).
