Advice please about finances as my partner is moving into my house.
We are both in our 50's with adult children, one of mine is at uni so still lives at home. We both have our own homes with mortgage, and want to keep our finances separate and the houses separate so inheritance for our children is clear. My house stays mine, his stays his. I understand (from fabulous advice on here) that this is a good idea and he must not contribute towards my mortgage or house repairs etc. He will be renting out his flat and this will be at a loss as the rent will not fully cover his mortgage, the service charge and the tax he will pay on the rental income (he's a 40% tax payer), however he wants to work towards paying off the mortgage and owning his flat outright. He can't reduce the mortgage as it needs to be paid off at retirement age. He's happy with this.
So my question is, what does he pay towards the running of my house that he is living in? Does he just pay 50% of utilities? Or a 'rent' payment of possibly more than 50% of utilities? Whats fair? We have similar incomes, I have more outgoings with one at uni and animals, he has the loss from the rental income not covering the flats costs.
