<prompt> Human: So, i have 40k saved up. My father wants to gift a loan to me in order to help me achieve the 20 for a down payment to avoid PMI. He also wants to go with no sellers help. It is a great deal and I am happy that my father trusts my financial decisions in terms of going in on a large purchase like this. He wants to own whatever of the house he puts the money down for and when I sell the house, he gets the money back. I am thinking of him as a silent investor. My question to PF is, any insight on how I should structure this with him? What legal documents? Do you foresee an issue with this? anyone in PF ever done this with a parent? If 20 down is 90k and i am only contributing 40k is that a bad move on my part to not have the majority of the 20?Side note: the area I live in is up and coming, fast. Major developments going on in a US city on the east coast.Any insight is appreciated.Thanks everyone, this was very helpful. I will definitely be examining this closer with my father. Assistant: How long would it take you to save up the rest of the 20 down payment?Human: I could be there in 1 year to 1.5 years if I really nail down on my spending habits.  <response>: With that time frame, its not worth it to mix family and money.
