Duplex w/daughter who lives on property

[Martha Price]

Hi:

I am have some money to invest and do not want to go in the stock market. My 25 year old daughter wants to buy a duplex and live in one side and rent the other but she does not have the income to handle this on her own. I would be providing 1/3 of the 20% down. I have no idea how to structure the deal so that it is fair to both. How are repairs handled? How are rent payments handled? How is the value of her living in one of the units handled?

Would love any input.

Thanks, MArti
