It is never a good idea to lend money to family. So why would buying a home from family be any different? It is a huge financial transaction! How do you agree on the price? How do you as the buyer know that the price is correct and fair to you? How does the seller arrive at the price? How do you determine the condition of the house? Do you really think house has nothing wrong with it just because it is owned by family? Do you think that the family who sells you the house will leap to the rescue when you find unknown problems exist in your new house? Who is going to pay the lawyer who draws up the paperwork? (You are not planning on doing that yourself, are you?) Who is going to pay the title company for their work - and the escrow company or attorney, as the case may be in your area? Are you paying cash? If not, have you gotten approved for a loan? Are you going to have inspections of the house? If you are going to have inspections, what will you do with the information that they reveal? If repairs need to be made or the selling family agrees to make repairs but the repairs are not made, what will you do? If you find out the house has problems that the seller does not want to fix what will you do? What if the seller offers to fix the problems themselves?
Are you and the members of the selling family ready to not speak to each other ever again?
