Multiple Applicants and Cosigners

[Paul C.]

I am about to rent out my first property and need some help in how to handle the application and lease process with multiple tenants and cosigners. I have a couple and 2 students(total of 4 that all know each other) that are interested in my property. I plan on running background/credit checks and require that they have 3x rent as their monthly income. The couple says that on their own they should be very close to atleast the 3x rent. The other 2 students dont have any income, but have parents that are willing to be cosigners. How should I handle who cosigns the lease? If the couple qualifies for the entire house, can they "cosign" for the 2 students or does it need to be someone else? If the couple doesn't quite have 3x the monthly rent should I require them to have a cosigner as well? Help is much appreciated. I'm in Atlanta, Ga fyi
