Its seems like the easy route is working with your tenants to keep them happy but if you give them an inch most of them try to take a mile.

"Give them an inch and they'll take a mile" - this can refer to PMs and/or tenants

Leave an inch uncaulked in the very back so leaks can be detected sooner than later. 

Stop what they are doing or leave.Right now they are running your operation not you.I recently had 10 inch move-in 3 days later they had a cat the next day they had a quit or cure issued, pay the pet deposit or leave.

@Absalom Young Yeah.. for months we tried to extend an olive branch and work with her... but if you give her an inch, she takes 10 miles! 

You can decide to not rent to people with green eyes, people over 6ft tall, people under 130lbs, or people who's first name starts with 'A'.

This all goes much deeper than the three inches below the surface where inexperienced real estate operators/investors frolic along with W.

I have always wondered how to get tall of the docs in order. 

The house was built in 1910, wood frame and I just re-checked the attic on our way through (we live out of state) yesterday - it has about 2-3 inches of old blown insulation.We of course didn't buy this as an investment property, so we are only $150 over the mortgage, insurance and taxes on a monthly basis.

@Derrick E.6-inch block plane usually works great on sticky door problems.
