The situation: mine and DH's mortgage is about 60% of the value of our house. Repayments are about 1/3rd of our joint income, but about 3/4 of mine if I had to pay it all myself (this might be relevant!). We are currently in the process of remortgaging our house, and the bank's affordability calculator has said that we could borrow about £120k more than we currently do, so some wiggle room there...
DB and his girlfriend live together nearby in a horrible flat. They've just been told the communal lounge is being turned into an extra bedroom so they have a kitchen plus bedroom. Rent is staying the same. They've looked locally and they couldn't really get anything cheaper that is a reasonable commute for both of them.
They both earn reasonably well, but nothing near enough to buy something. I would therefore like to buy something with/for my brother and have seen a 2-bed flat nearby. We have said the set up would be they are responsible for covering the mortgage each month, so could chose whether they rent out the second room and pay less, or pay have the place to themselves. They would also be responsible for all repairs. Ideally, DB and I will get a joint mortgage and I put down the deposit. We've agreed who gets what equity if/when the flat is sold, and I trust him 100%.
Because of tax implications plus the higher interest costs, I really don't want to get a Buy To Let mortgage, but if I apply for a joint mortgage with DB, they will take the entire repayment on my mortgage (ie assume that DH doesn't pay any of it) when working out how much to lend. The affordability calculator will come up with a 'worst case scenario' where I'm paying both mortgages on my own, and will knock me back, as both repayments would be roughly equivilant to my total take-home pay each month
Is there a way around this?
A friend suggested applying for the mortgage and telling them DH and I are splitting up and our house is being sold, with him staying on and paying the mortgage until that happens, which means the bank will disregard my main mortgage payment. I'm a bit concerned about that level of lying, but she said that reconciliations happen all the time, and the bank won't care as long as the mortgage is being paid, and as my brother will be a joint applicant, and will be living there, they can't port the mortgage to a buy to let one. This seems too good to be true, but I don't know how to investigate it without ringing alarm bells..!
Does anyone have any good ideas? I don't want to talk to my mortgage broker at the moment, in case she smells a rat and it jeopardises our remortgage...
