Tenant wants to break the lease

[Rich Rodman]

I own a single family with four girls renting it out. They all signed one single lease but split the rent evenly amongst them. I had a call from one of the tenants yesterday explaining that she wants to move out of the house and in with her boyfriend, asking if she can break the lease. 

What is a good option here? I could tell her she can't break the lease, but I think providing a real solution may be a better and more frictionless option. My thought is to give her 60 days to find a new tenant to take over her lease, and I'd obviously look in that time as well. 

Thoughts?
