I work in data science at Freddie Mac where my team crunches a lot of mortgage data for machine learning, data mining, and data visualization. 

You've got such a well-oiled machine, why mess with a good thing? 

They are a machine, they go to the court house everyday for court case related to eviction and they file online.

Like a self-fulfilling prophesy  The fact that it gave you a hinky feeling goes to show that it's not something you'd be comfortable with, so that's a good indicator that your tenants wouldn't love it either.You just can't treat people badly, and then expect them to be a long-term ATM machine that spits out rent every month forever.But, of course, your PM probably makes money every time the place turns over, so they don't care if they are irritating the tenants and having to get a new tenant every year, because none of the tenants want to stay after their lease is up.

They are not going to be real interested in your "value add" or your increased NOI because you kicked out the laundry vending  company, bought your own machines and doubled your monthly laundry reciepts...

Her laundry machines are in the basement, but we are very close to just locking her out of there regardless since she hasnt paid rent anyways.

I had a washer/dryer combo unit installed as I didn’t have room to stack machines. 

So yes, at some point things like the water heater and laundry machines DO make a difference.
