How can I make this a win - win?

[Brandon Becsi]

My mother in law has a home that she hasn't lived in in over 10 years that she is trying to sell. Its an old farm house in Virginia on 19 acres. She's asking $125k on open market but I could probably get for 100k being family. It needs about 10-15k work immediately to make livable/rentable. After basic repairs ARV around 160k-180k. She owes 45k on it and her current payment is $500mo. What is something I could offer her to be win -win for both of us? I want property for rental and to have the land. I could rent for about $1200mo.
