Tenant's boyfriend moved in

[Andrew S.]

Happy Monday BP, 

I have a good tenant who has moved in her boyfriend.  I was notified after the fact. They have been a good tenant for ~8 months into a 12 mo lease and have discussed renewing the lease in other conversations.  They have been proactive with other communications.  I asked their boyfriend to complete a rental application and a background check, but they have been avoiding/ slow on returning it for 2 weeks now. 

After some research, I decided to have their boyfriend not be on the lease but rather an approved guest.  If they break up in the future, I don't want to deal with who gets the place, etc. She is still responsible for the rent and her original security deposit.  The lease lists guests not allowed > 7 days, which has been discussed in person with the tenant and her bf.  

Should I care much about having her boyfriend complete a rental app (employer info, rental history) and a background check?  

Thanks
