They love it there, have somewhat low income (one is a hair stylist and the other works at a restaurant).   

Is it dry camping?

You really can't keep water out from the inside.If you want a dry basement, keep water away from the outside. 

I was pulling my hair out dealing with check ins and outs, cleaners and more!

Gotta work the math -- and it isn't as cut/dry as some posters above suggest.So that brings up: how much does a property manager take out of your hide?  

My contractor turned out to be a scam artist and I am certain he is singlehandedly responsible for about 50% of the gray hairs on my head.

The entryway floor and all the floor I could see was full of hair.

FHA/VA loans trending a hair above 6.5%.

Just because hair is found inside a clogged drain the clog is not the tenant's fault when they rent a unit with ancient plumbing that was 99% clogged the day they moved in. the poor drainage system snags the hair and there is nothing the poor tenant can do to prevent the drain from clogging.

Its never that cut and dry.
