Hello, I am Keith, one of the experts on Just Answer, and happy to help you with your question.
Yes, I am sorry but Just Answer has managed to loose the post.
It is nothing to do with the tax office, they cannot refuse to allow you to take out an additional loan. They have no authority in that matter. Any interest charged would be allowable against the rental income from the relevant dwelling.
I do hope that my reply has cleared the air.
Well, in theory yes, but unless it went into rented property support then HMRC would have valid grounds for refusing to allow the interest against rentals.
Delighted to have been of assistance.
Thank you for your support.
