Let's look at extremes to understand the concept.  

You could offer it to a seasoned flipper with the concept when it sells, help them to set a reasonable time frame, they pay off your mortgage.

Basically My job is to find the deals that are so good, that pretty much any cash buyer will take it, as long as the numbers are ran correctly.

I watched the webinar in the Brrrr strategy last month and I didn't quite grasp the concept of this strategy.

My goal was to have him hire subs, mange contractors, bid jobs and basically handle the rehabs for my flips and rentals.

Older homes in our area often have a functioning forced air furnace with ducts for all 1st floor rooms but gravity registers (basically holes-with-grills through the 1st fl ceiling/2nd fl floor) for the 2nd floor.  

I can understand the desire to avoid large costly legal bills but there is not going to be an easy way around getting the right attorney to defend the right concepts of the whole situation.  

I recently bought a strip center in City of Gray, GA which is basically vacant with only 1 tenant, but the water and sewer bill was around 600$ (the usage was well within the allowed 2000 gallons for the base charge).

This ultimately got resolved, I basically told them I won't be signing off on any contingencies unless we get the signed estoppels.
