Hi, I borrowed a loan from a bank in Hong Kong before I came to U.K. I used the loan to buy a new house in U.K. after arrival U.K. I let out (rent) the new house. The rent is used to pay the loan interest to the H.K. Bank every month. I need to pay interest of the loan from the bank. As it is an expense of renting out the new house, I would like to know if I can reduce my tax revenue (rent) from my new house in self assessment. Thank you.
