Tenants Bf has apparently moved in unannounced

[Tony Cavalli]

I was made aware that my tenant's Bf or baby daddy has apparently moved into the house with out notifying the property manager or myself... How should I handle this situation? Rent still comes in on time, but my manager has stated that when work is being on the property that this gentleman is always there by himself playing video games or something. On top of that a nice older (hotrod i guess) car has been there as well. I believe that its his...  Do I step in and make him fill out an application and run his credit? or leave the issue alone since rent is coming in on time?

from personal experience DONT LET IT SLIDE.  Had a boyfriend move in once and while I did not realize he had until too late, (it was a medium size apartment complex) within the next month the 8 sheriff officers were there and kicked down the door to haul him off due to outstanding warrants.  I would not run his credit but I would make him do an app and run his background.  You want to know who is living in your property at all times.  If he refuses to do this then you know there is a problem and you need to get them both out asap.  If he does it no problem then you are home free and if they are good/decent folks.  they will not mind a bit and will understand.
