I know places where the squatters would be leaving in body bags.

I think there are definitely going to be some people 'holding the bag' when the music stops. 

What keeps each partner from just walking away and leaving the remaining partner(s) holding the bag?  

Sometimes I buy microwave popcorn and leave a bag or two in front of the microwave. 

This old bag again. 

We came with batteries , a few new smoke detectors to replace ones not working, lightbulbs and a flashlight, and tool bag. 

My concern is that he starts to look at the numbers (before, during, or after) and realizes he isn't really making any money for all the work involved and jumps ship leaving you holding the bag. 

The house had been broken into a couple times and we found a bag of the good stuff during clean out.

I've arranged for my PM to take a smaller percentage since I'm still the one handling bookings, doing small maintenance and keeping up with supply inventory.A better example is the service I get from my housekeeper at my new rental in Tennessee: she does the post-stay walk-through, cleans, and provides or maintains the inventory of supplies (she provides quite a bit: trash bags, toilet paper, basic toiletries, dishwashing soap, hand soap; the things I provide, she'll let me know when supplies are low, and I'll have new items shipped to her house).  

Trying to find the bottom dollar tow is pointless, you may as well start bagged for free towels.
