I've seen as many as seven...surprising the structure could hold the weight with added load of snow in winter!

Hands on expectance far out weights reading books.

Minimal upkeep, industrial strength supplies at cheap prices.

I’d be unnerved about losing 500$ a month If your going to Subsidize their rents they can Atleast pull their weight around the place instead of just sitting around watching jeopardy in their craft- matic adjustable beds  .

Using materials with a higher density than water, composites, metal, plastics etc. etc. you can either do something and hope it floats, or you can find the necessary equations and figure out first the weight of it all, cross reference that with the water displacement weight, and calculate FIRST whether the boat will float or not.Everyone that does DMM is basically building boats this first method.EVERYONE that does DMM is  shoots arrows in the dark, and HOPE some will stick.

In my area, most of them last for about 2-3 months before giving up.  Keep

Not to mention since they are already going through Chapter 13 BK that means they already have multitude of payments on numerous assets in which they’re behind on, so relieving them of a monthly mortgage may be a huge weight lifted off their shoulders.

Justin,Look at Homeaway and Airbnb for similar properties, then see what their rates are and see how full their calendars are.This should give you an idea of how much they are bringing in annually.If you put it this in a spreadsheet and make a column for each property it should be easy to do the math.Then you'll need to deduct for Mortgage payments, cleaning, utilities, upkeep, advertising and Property Management.You can pretty quickly see what the numbers shake out to be.You could also play with the numbers like different mortgage payments, PM or doing this yourself, different rent levels etc.You may be happy with a 50% or 75%  offset on your overall costs since you primarily want a second home/vacation place for your family.

Thanks for your thoughts @Robert Gilstrap, I'm sure that for a novice landlord a PM company is worth thier weight in gold. 

The only real difference is you will only weight the part of the monthly rent they have to come up with that is not covered by their voucher.
