Sublet (ish) arrangement

[Matthew S.]

I have two tenants ready to sign a lease. One will move in next week, the other will move in in May after she graduates. To cover the rent in between, they want to get someone to live there until May. I plan on screening that person like they were a tenant, but how would you handle the lease? I was thinking of keeping the subletter off of the lease and let the arrangement be between him and the tenants, but what are the pitfalls of this? How would you handle this situation?
