Hello my name is ***** ***** I will help you.
Just to be clear it's the property you live in, not the one you rent out which has a mortgage?
Thanks. The answer is no.
If you had taken a buy to let on home 1 only which is rented out then yes the interest would be deductible.
But you can't deduct the Interest for home 2 because it is not let out. It needed to have been secured on home 1 which would have meant it was allowable.
I am sorry if this is not the answer you want and certainly not the one I want to give you, but I have a duty to be honest.
Can I clarify anything for you about this today please?
If I could invite you to rate my answer before you go today please, otherwise the site does not credit me for the time spent with you today. Thanks and good luck. Alex
