trying to get financed to buy a home or looking for rent to own, what should I know?

I'm getting evicted from a house I've lived in since May. I never had a lease or anything, the landlords were friends of my fiance's mom. I'm tired of renting to be honest, so I'm going to try to get financed to buy my first home. my fiance is in college and I'm in beauty school, my fiance is employed. we have a 2 year old daughter. since we are a young couple I'm sure our credit isn't great if we even have any. we're also a low income family, but we are not trying to go through section 8. our rent was $450 & we always had it on time. we also have a lot of friends offering to move in with us and pay shares of the rent if they can have their own rooms. If you have any information or advice you can give me that would be great, thanks!
