I like your model for the start and end dates for your units.

I realize we’d probably want to bring in a real estate attorney, but I’m assuming there are models in place that are probably well-established for such a partnership that I know nothing about.

Travelers, Farmers, Steadily are some who allow this model.

I think you'll see the model continue to evolve in the future, with more "next gen" firms popping up.

Preforeclosure's best model is "going down with the ship". 

This is the model # at home depot.

One being a wholesale model, the other I call the profit maximizer.  

I can run and model numbers and am a CPA so comfortable with the finance side of things.

Now you are telling me my critique of of your business model "gives you motivation".

Kudos to you for doing something to create a secondary income stream. there are 5 income streams in RE rentals, possibly six if you do things a certain way.The reality here is your model (buy box) is suffering from too high an entry and too high a cost of capital.
