I would like some advice regarding buying a house for my parents. My parents live in Surrey and we live in London. We cannot move out of London due to job/ school etc. My parents are getting old and want to move closer to us, which I think is a good idea. They have a mortgage free house worth about £400K. If they were to buy a house near us, they would beed at least £700k, so that would be £300k beyond their budget. They are retired and getting a mortgage in their name is impossible. My parents have asked us if we could get a joint mortgage so that I could take care of the mortgage which we are happy to do. Mortgage payment is not a problem for us. Our house is worth £800k and we have about £200k left on the mortgage. My husband and my job pays us well with an annual income before tax about £120k.
I am worried about the tax implication if we buy a second house with our parents. If we buy a 700k house, my parents will pay an upront amount of 400k, we can put 100k deposit and get mortgage for 200k. But does it mean we pay the stamp duty for second house for all 700k? Is it possible for my parents to pay stamp duty for their share of 400k (moving house stamp duty) and we pay the stamp duty for 300k ( second house rate)? Get two titles for the same property on a shared ownership property? I dont have any siblings so there wouldn't be any conflict with regard to inheritance. I just cannot think about paying second property stamp duty for the full 700k. Would love to hear from others and no judgment please 🙏🏻
