Unauthorized occupants in LTR?

[Cory Lucas]

Hey BP, I've been reading up on all the posts I can, but I'm to the point where I'd like some specifics answered in regards to my personal situations if you please. Thanks in advance

So, I have one residence that I just re-upped their lease, when I received their updated tenant info they have an extra person listed on there. So, for one I'm happy they were forthright, but at the same time it's not someone listed on the lease. They've been good tenants so far, hardly ever call for issues and pay on time, very nice, good people. That being said I of course don't want to rock the boat, but know I can't let this slide. So, any good thoughts on how to go about it? My thought was send them a message saying I see we have so and so listed as an occupant, we'll need to run a background check and get them added to the lease. But my real kicker of a question is do I raise rent more or let that be? I feel I should, but of course that has the potential to sour the relationship on their end. My remedy I've thought of so far is to say we need to add them to the lease or they would need to vacate the property, if they'd like to stay it's an extra $100 a month if they're willing to pay it providing their background check comes back ok and we would need to further prove income? Thoughts?

 My second situation is I believe I have someone residing in a residence that has not been brought to my attention. Do I just go by for a certain amount of time and document the vehicle I've noticed in the drive? Pretty sure I know who it is too as this person was there one day when I had to do some maintenance, claimed he was just there temporarily, but I'm pretty sure he's staying there now. Then any advice on following through on that one if he is indeed staying there?
