Boyfriend is coowner of a house with his sister, he wants to sell but she doesn't
Rent the property?? Is that a possible solution? Since selling the house is not an option and living in it isn't either, then perhaps renting it is the way to go? Since no explanation for the sister's motives is given, i'd speculate it is a mixture of emotional and financial concerns. Maybe mostly emotional. I imagine letting go of the one physical thing that has memories of you and your parents attached to it is very difficult. I don't think getting a lawyer or doing what's convenient for only your boyfriend is the way to go...But that's my own personal opinion. Clearly, he only has one close family member left alive. Creating permanent wounds in that relationship will cost more along the way. And quite frankly, if the house is owned 50-50, don't you need both owners to sign the deed to sell the house anyways? If renting is not an option, then maybe refinancing the mortgage to lower payments? Or Airbnb it only half the time? Or rent it out for events to help with payments? Or ask the sister for a little money...Not for half the mortgage, but at least a few hundred dollars to maintain the house and heat. If she is indeed concerned with the property, then maintaining it to prevent serious damagae is in her interests, no matter her income.
