My husband and I have been renting our house from my grandmother for 4 years now, and we are ready to buy the house from her. We are guessing the house and property will value around $90,000, but we haven't actually had it appraised yet. But I know that my grandmother is going to take money off of the actual value, and we have been talking about between $65,000 and $70,000. We want to add an addition and a garage to the house and our goal is to get an additional $50,000 added to whatever final price she decides to go with. What I want to know is how hard is that going to be and are we going to have problems with it being a family member selling to us for cheaper, or does that help us out in the end?
