Three roommates not getting along, plans to leave one behind

[Kay M.]

Hello Everyone,

Tenants in my rental are not getting along with their roommate.  Two of them are brothers (tenant A&B) and are planning to leave.  I have been getting rental verification requests from other properties they've applied to.  The 2 brothers moving out (tenant A&B) say that once they find a place, they will give me plenty of notice, but say they do not want to tell their roommate (tenant C) that they are looking until they find a place, because tension between them is already high and they don't want to make things worse.

My concern is, that these tenants have been in my property for 10+ years.  Originally, I approved their application to rent my place based on Tenant A income.  He was able to pay for the rent on his own income.  Tenant C, could not afford the place on his own, but since there were 2 other roommates, I thought it was ok.  If both tenants leave, I am worried that tenant C will be on his own, unable to pay for the rent and with the eviction moratorium in place, I'm unsure what to do with the lease which ends in July.  I'm suspecting the 2 are planning to leave around the time the lease ends or leave earlier and give me 30 days notice.

What are the next steps I should take or do I even have a choice?  Can I ask for a another credit check for the single remaining tenant and based on that, ask him to sign a new lease?  Any advice for next steps appreciated!
