Ive been in the home rental business for 35 years, enough time to see the same scenario before, but it leaves me just as vexed this time as it has before.

The issue is a young couple, about 23 years old, who have been together for a year. She is openly and admittedly 'madly in love' with her boyfriend, going so far as to announce on the initial walk through, that they want the suite because "its so quiet and peaceful and we are going to have a baby here" A bit too much information.

They were fine during the interview, and all their checks were passable - both former landlords I contacted gave them a thumbs up for paying their rent on time and keeping the place clean. Everything was fine except for his credit score which was very poor - but thats not unusual for someone that young who is still learning how to control their finances.

There is another young couple in the lower suite and they met and exchanged pleasantries and seemed to hit it off initially. But one week in, I got the first text from the basement tenants saying that there was yelling and screaming upstairs. I was startled because it seemed unusual compared to the public face they presented. I asked the tenants to inform me if it happened again. Maybe it was just one very bad day I hoped.

It did happen again. The next day at 5 am they were shouting so loudly that I could hear them over the basement tenants phone. I asked the tenants to call the police because it was domestic violence. They were about to call when everything went quiet again and they chose to wait.

There was a lull for a bit and then the third week I got an early morning text again. This time they were not only yelling at each other, they were screaming at another couple, friends supposedly, who were staying with them. There was loud banging and "it sounded like chairs being thrown around"

I told them to call the police, which they did this time but by the time the police arrived everything was calm again. Moments after they left though, everything erupted and the two guys ended up in a fight on the back lawn, Fists went flying and someone got punched although at this point its unclear who punched whom.

The police were called back and according to the account I got, the boyfriend was arrested. He says he wasn't and the police wont give me the report without his permission.

So yesterday I went to talk to them and inspect the house. I cant see any visible damage however it could easily be hidden by the goods piled against the wall, they're still unpacking as they've only been in for a month.

And then my dilemma begins. I KNOW this is a toxic relationship. Ive met this kind of guy before. Smooth talker, good looking, believes he can charm anyone any time. When I told him about the three reports of excessive noise and violence his first reaction was "it won't happen again" and his second was "I will call the other tenants and explain, Im sure we can work this out"

No buddy, no you cant. Because you're an abuser. And you'll do what all abusers do. You'll try to quiet the noise for a time, try to make your girlfriend use a forced whisper instead of an open cry, but it will only be a matter of a week or two and you're going to lose your temper again and we'll be right back where we are now, but probably even worse, because your character has been exposed.

And then I struggle with my place as a landlord but also as a caring human. I LIKE these people. They were charming and fun to get to know. I did extra work for them, getting new appliances in place because she's a specialty cook and loves to be in the kitchen. I made sure everything was 100% because I wanted them to be happy and have a nice place for them and if it happened, their new baby.

But now Im very concerned for her future. She doesnt seem to realize just how deep she is into this toxic mess of a relationship. His comment was 'we fight like most couples' and I abruptly cut him off: "NO! NOT like most couples! Most couples dont wake up the neighbors at 5 am with a screaming match and have a fist fight on the lawn where the cops get called" He looked slightly sheepish for a second and then went right back to his charm defense, saying he would work it out and they just needed 'another chance'.

The reason I think I may want to say more is because of Mercedes. She and her boyfriend rented from me about 10 years ago. It was the same scenario - charming, good looking but very angry boyfriend who lost his temper and went around the house damaging walls and smashing a porcelain sink. He was so rabid I actually brought a friend along to give them their eviction notice because I feared for my safety. That wasnt unjustified and his rage was palpable and extremely scary.

But when he was out of the room I asked Mercedes if she was ok. She said she was nervous, scared, but ok. I said 'I hope you're not going to go with him when he leaves' and she shook her head. The light bulb had come on. "No, the second he's out the door Im out of here. I hope I never see him again." Thank god she was finally seeing things clearly.

I came across her again a year ago online and just sent a friendly hello and if she remembered me and the house. She not only remembered me, she thanked me for helping her escape her hellish relationship. She said she was now in a very good and loving relationship and she couldn't believe how blind she was to even move in with Mr. Toxic in the first place. She said their eviction was a important turning point in her life.

And I see Mercedes in this new tenant. Im just not sure she realizes what she's got herself into. Or else she does and she's not sure how to get out because I cant imagine how violent his reaction would be if she tried to leave.

Which leaves me stuck. They are new to this area. They said they dont have many friends and family is a long way away, so there's no one close who is seeing what the basement tenants and I saw. And we're not sure what to do. The basement tenants are so scared of him they dont even want to be in the same house.

What do you say or not say to someone in this situation? Saying nothing seems irresponsible. Saying too much seems dangerous at least to her safety. So... what do you do? How do I figure out if she even wants help? And if I say something too soon, or too late, he may turn on her and get even more violent...
