Thank you for your reply
I will be expected to provide proof of my residential address to the solicitor who will be handling the sale of the house, and also to the conveyancing company and estate agent. I have plenty of proof that I am resident in the Buy To Let property but I have nothing registered at my father's home as I am not living there as yet. I was wondering if I should change my resident status to reflect my father's address in anticipation of my imminent relocation, or will I be solely expected to provide proof of my residency at the BTL property, as that is where I live in actual fact.
Do I need to inform my mortgage lender that I am living at the BTL property or is this uncecessary as they are not going to check now presumably and will just be satisfied to have their mortgage repaid?
