I make a plastic tray out of that thicker clear non-adhesive shelf liner to protect the cabinet from leaks.  

They gave me a large plastic bag what holds 50 lbs of quarters (it is some sort of security bag), I weigh out 50 lbs of quarters, fill the bag, drop them off at the bank about 3 times a year, they credit my account $1,000.

We had one of those plastic kiddie pools that we used as an "exercise pen."

It looks in decent shape, has 4800 miles, but has scapes in the plastic on one side where it looks like it was dropped.

We now do quarterly inspections of our properties to make sure tenants are not painting, changing light fixtures, installing backsplashes, staining kitchen cabinets, spray painting the patio, etc.

I have one door and my primary residence that I rent out the upstairs.In my rental over the last year I have had the following issues/calls:In the first week (when I think you will get the most calls from tenants):Toilet seat was wobbly (It was-very easy fix)Toilet seat wasn't flushing (plastic trip device broke. $10 fix)After that I had 2 calls over the course of the year:The AC unit wasn't draining properly and was leaking out into the house.

Covered patio to sit in the fresh air with some grass and flowers and talk.

I feel like if the plastic underpayment pad is put on properly, it would be adequate protection.
