I don’t recommend what I’m getting ready to describe, because I’m a seasoned pro, and know how to protect my assets from a character I’m about to describe, but…
If this were me, not knowing any more about this situation, I would first attempt to sign up the drunk boyfriend, after running a credit report to confirm he’s an idiot, unable to handle money; was actually evicted by a half-a-dozen other landlords, and just for giggles, is in fact, a registered sex offender. Then, I would offer him the opportunity to be added to the lease, in return for two hundred dollars per month on top of what I’m receiving now in rent. I also want an additional deposit of “x” dollars (depending on what the primary tenant had already deposited, but just to psychologically reinforce with the potential drunken, child-abusing deadbeat that nothing in life is free, and that we have a business relationship.
Now, in real life …the drunken, child-abusing deadbeat will not take me up on my offer. Why? Because he wants free sex and handouts. Why buy the cow, when the milk is free? Never mind he’s not into liabilities and accountability. That’s why he’s shoplifting a place to live from his girlfriend and from me.
Meantime, I remain the good guy, because I didn’t say ‘no’ to him living in my property. I just explained, “How he could do it,” and he chose to reject my generous offer."
*** That all said, everything is in the open. Drunk, pedophiliac boyfriend now knows the ground rules; realizes that I know he’s been living in my property; and I’ve explained what will happen to him, and everyone involved, if the rules aren’t maintained as agreed, such as forfeiture of their deposits, breach of lease, unlawful detainer, court actions, further damage to the primary tenant’s credit; perhaps a recapture of losses from the cosigner, and the list goes on. And/or drunk boyfriend can find another place to squat.
Anyway…
