I currently own my own home and rent out a room which covers roughly half of the mortgage. My current tenant is moving out and I will likely get someone else. I have 4 bedrooms. I am in a relationship that we both see as long term, we are both in our thirties, we have discussed buying together in the next year or two and I would sell my property then. I have asked him if he had thoughts on what our financial agreement would be and he said if I wasn’t to have a tenant he’d pay me half of everything but as half of my mortgage is being covered he’d pay half expenses, food etc. I understand that he would be contributing to my equity should he pay rent which is not necessarily fair and I don’t want to sour the relationship by monetizing it. He has a good financial attitude (savings, investing) and I get that money he is saving by not paying rent would go towards our own home. The relationship is not very old so it’s in the back of my mind what if it doesn’t work out for one reason or another. Am I being a bit foolish here with this arrangement?
