Coming at it sideways, if he is looking to live in it eventually he may be able to get a consent to let, but these differ between lenders and will most likely increase the premium and only be good for a year or so, I'm sure a mortgage company would be mighty suspicious mind if he tries to do this straight after purchase. Get a BTL mortgage if it's a BTL property, and then life is a lot simpler, or save £100 pm on repayments and chance it, plus getting it rented through an agency may be tricky.
