@Brody Veilleux, to say "cash flow is tax free" is, at best, grossly misleading and, at worst, flat out wrong.What is true is 1) taxes are based on net income and 2) cash flow does not equal net income. 

Depending on the state he will likely not have any sort of case at this time.

Sort of like a fishing village, but great beaches, parks, etc. 

You'll need some sort of active income, whether it's wholesale, fix and flip or lending.

Maybe they could do some sort of private reverse mortgage?

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.The City of Detroit has 183 Neighborhoods we’ve analyzed.PM us if you’d like to discuss this logical approach in greater detail!

And what is the best way to sort and filter it before feeding it into these call center servcies?

I really do not want to back out of the deal, but curious if I could negotiate a reduced price or something of the sort.

They've had time during the week to get things sorted. 

Any sort of walkability is a huge plus since you can't add much more value other than a typical remodel.Good luck!
