I'm just about to move my elderly parents into a house I own but do not live in prior to this I was renting this property out but as my parents Heath has deteriorated and where they live is not a suitable option for them it was either this or the go into care which I did not want. The issue I'm having is I want them to feel secure there I will never need the house and I will continue to pay the mortgage however I do not want any payment from them, the deal we made was I will pay the mortgage they can pay bills ( electric & gas/ water/ council tax / broadband) but do I need to do anything to make this all happen officially / legally? Is it still classed as renting even tho I'm paying the mortgage? Do I need to declare it anywhere? Any advise would be appreciated :)
