First rental home. Advertising/contracts

[Gleason Jones]

I'm 20 years old and in my junior year of college. I recently just bought my first rental home (3 bed two bath,residential zoning) with a co-sign from my dad. I have a small lead on a family that might be interested from a friend. Other than that I don't really know how to advertise the house or what all should be included in the legal contract with the renter. So any ideas would be greatly appreciated for a newbie. Thanks
