One tenant wants to leave, one wants to stay - what are my rights

[Connor Riley]

Hi BP community!  I'm looking for some advise - I'll try to keep it simple and spare you the details.  

One of my properties in Denver, Colorado has two tenants (two 25 year old friends) both on one lease.  Tenant-1 told me in February that he quit his job (prior to the whole COVID-19 issue).  Now he can't find a job.  I am being told by Tenant-2 that Tenant-1 has moved back in with his parents (out of state) and he expects to quit paying rent starting in May and he is expecting his full security deposit back.  Tenant-2 wants to stay in the house and finish out the lease (which is only a few more months) but he can only afford half the rent payment.  

I suggested that they find someone to sublet for the remainder of the lease OR I would be willing to start a new year long lease with Tenant-1 and someone new.  Tenant-1 only wants to finish out the lease (not start a new lease), he doesn't think he can find a subleaser for the last few months, and on top of that he "didn't sign up to live with a random roommate".

I'm trying to be sympathetic with the COVID situation but I'm not sure what to do.  Any adivce?

Thanks in advance!
