Buy to Let Mortgage in Landlords forum Posted December 20, 2010 · Report reply I'm just looking at options on buy to let mortgages and I can't see much at a decent rate for anything less than 35% deposit. While I can do this, its a bit of a stretch and I'd like to hold some savings back. The situation is that my Mum is presently renting a house where she wants to stay, but the landlord is looking at selling. She retired recently and the way I'm looking at it is that I have a long term trust worthy tennant which covers mortgage and upkeep and that if ever in the future my mum needed care then I would have equity in the house to cover it. I have other businesses so I'm not worried about turning a short term profit on this on the rent I'm just looking to build up equity in the house, but I'd really prefer a half decent mortgage deal on 20% deposit over 25 years. I've checked out Money supermarket etc and I just don't see anything that's floating my boat in terms of mortgage deals.
