This is being phased in from 6 April 2017 and will be fully in place from 6 April 2020. For the 2018 to 2019 tax year, you can only claim 50% of the cost of getting a loan, or alternativefinance to buy a residential property that you let, and 50% of any interest on such a loan oralternative finance payments.
