There is a good chance this tenant will resist moving - and may use every trick in the book to delay that at your expense - because they are getting such a screaming deal at your property.You are wise to systemetize your rent collection. 

The minute they crack the door, he chops the head off the chicken, screams "Baphomet!!!"

The kids scream, Karen runs, and I go to look for the broom, but by the time I had my weapon the mouse had hid somewhere in our master bedroom.

I remember shaking the little guy at three in the morning and screaming STFU!!!!

On monday i am calling the Child protection services on these people for smoking that dope around her baby, who I think is a drug baby because she screams at the top of her lungs for minutes at a time.. some times for over an hour.  

If you're trying to schedule showings around Airbnb visitors, cleaners, etc. it might be a little more challenging.  

Same lease as everyone else--how many visitors, how many nights a month, etc. 

It is time to evict her.And for those who think this is cruel, I'm one of those "elderly" folks (I'm about to turn 65 in a couple of months and if I get one more notice in the mail about Medicare supplemental insurance I'll scream) and a breast cancer "survivor".Your tenant does have a daughter so she is certainly not alone in the world.  

I could either pay a visit or send a letter.What do you recommend?

I tell him this . "  You are renting the house and the land , you are in charge of who you want to visit or be on the property ( except for me doing maintenance or inspections )  I wont put up signs , but you can , and if someone trespasses you have the right to have them arrested .
