Lease with roommates

[John Cava]

Hi - quick newbie question for the Forum. Renting out a 3 bedroom single family house in Portland, OR with 3 roommates - I know the parents of one quite well, but not the other two and there is uncertainty about one of the roommates.

Is it best to have a lease (1 yr) with all 3 of them on the lease, or should I ask for just one of them to be on the lease? Same with collecting rent - ask for a single check or accept 3?

Thanks in advance for your thoughts. john
