Tenant Issue - Thoughts?

[Elliot Larkin]

Hi There,

I've got an issue I haven't encountered before as a landlord, the lease is just under the girl's name. Today is the last day of the lease for a sfh I own and I got a message from the boyfriend of the girl on the lease saying, "----- and I broke up and she left. I'm running behind on the move out, I'm planning to be out by January 15th." 

Context: Property is in Florida, my mother-in-law is moving in and doesn't need to move in immediately (she is flexible), the guy who texted me is not a good apple (the only reason I rented to them is because the girl is responsible). 

I like to avoid evictions for the sake of damage to the property, time it takes to evict, and cost of eviction. If I don't file an eviction, what form should I use to extend the lease to the 15th since the girl on the lease is gone and now it is this guy?

Really appreciate your consideration, Happy New Year!

Id tell them it is fine, but we expect Januarys rent to be paid in full
