Renting a house owned by a family member?

[Patrick Crehan]

So this summer my girlfriend and I are planning on moving in with each other. Her aunt owns the house that we are looking at and planning on renting. My question to you all is how should we go about it? What are some good strategies, advantages/disadvantages of living in a rental property owned by a family member. Pros? Cons? The people renting it now are paying around $800; could we maybe negotiate a similar rent with agreement upon self maintenance once the current renters vacate? Also what are your guys thoughts on rent to own/lease options or mortgaging in the future? The house is very affordable. Any tips, tricks or ideas would be awesome. Thanks
