I have received an inheritance from my grandfather if 200k. I could use it to pay off a large chunk of my mortgage (currently 350k) BUT I would like to be able to access the money should I need it. With everything that's going on with Covid I am worried I could lose my job and would need this for redundancy. As such I was considering buying a BTL and then I could sell it if needed. However if I do this and there is no mortgage will I be taxed at full wack on the rent? I am quite risk adverse and wouldn't want to do anything risky with it but at the moment it's just sitting in the bank - doing nothing!
