Tenant wants to add boyfriend - as sublet

[Rhonda Blue]

What should I do.

Tenant so far has been very good.

She just recently asked me about adding her boyfriend. She is a single mom recently divorced past 2 years with 3 kids and has a good job and is  a quality tenant so far. 

She asked if she could move her boyfriend in. I had him fill out an application and do a credit report. He has awful credit and I can't verify his recent rental history seems sketchy self employed past 8 years not verifiable. Past child support arrears on credit bankruptcy under 550 score. 

I would not rent to him. 

What do I do. 

She wants to remain primary responsible for rent. 

Do I ad an addendum that he is allowed to reside there not liable for rent. 

I would not rent to him.

UPDATE: I did let my tenant move her boyfriend in. I mentioned to her that I wanted to NOT change the lease so he would reside there as her guest. SHE LOVED that idea because her home and her children were her priority. GOOD thing to because 3 months down the road she had to have him forcibly removed from the home by the POLICE due to Domestic Violence issue and the Police told him that he was a guest and had no rights under the landlord tenant laws to remain in the home because he had NO LEASE. It worked out for my tenant and for us. 

She has since moved to another state to be closer to her family but took fantastic care of the property.
