Hi I bought my house in 2005 as a single person and have been claiming mortgage interest relief as a single person since. I got married last year and my new wife and myself now live in the home. So I'm wondering if I can now claim mortgage interest relief at the married rate. Or would it make sense if my wife also claimed mortgage interest relief as a single person. I paid 4500 in interest last year. At this amount will I stand to gain anything from changing? Thanks in advance!
