I hope this is the right place to post, I wasn't sure whether to put it here or in Property.
DH and I live in a house that is currently mortgage free. He bought it before we met and owns it jointly with his Father. At the time his father's share was supposed to be an advance on his inheritance in order to help him out when he was made redundant, the agreement was that the will would reflect that he had received this money so his sister would get more.
This was a long time ago. There was never any agreement to pay rent but equally his father has not contributed to upkeep or improvements made to the house which have been significant.
I live in the house as DH's wife but don't have my name on the property.
SiL is now experiencing difficulties and FiL obviously wants to help her out too. He has asked if we can buy him out of his share in the house to enable him to help her buy a house.
So I am looking for advice on how we do this both in terms of practicalities and how we do it fairly. I have never purchased a house so don't know much about the practicalities.
My savings aren't enough to buy him out so we would need a mortgage. I don't know what we would be able to borrow or for how long.
