Once I have achieved financial independence, I would probably be my own GC on my own investments.

Do I have to financially qualify the buyer and where to find the guidelines to follow?

Probably trying to hide some bad financial history. 

If the former, then I stand on my post.

I will share where I am today financially and what are my future Real Estate Investing goals are.

The financier of the project owns an instrument rental company and would like to make their headquarters out of the parcel.

We have gone out to look at the property, reviewed the financials back to 2016 and met with the seller in person a couple different times.

Our host is Kit Crowne at Righttrac financial.

I've fixed pretty much everything unless it was over my skill set (replacing capacitor on A/C system, for instance; landlord told me when I moved in it was okay to repaint or whatever as long as it improved the house), my neighbors love me - they've told him so; I've resodded the yard twice (FL grass sucks with a dog), had the landscape crew redo the trees in front so they look good, replanted flower beds (perennials), power washed the house every year after wet season ended, ensured the pest control worked...The BUT part ...As a sole practioning consultant (pre-IPO weakness remediation, large financial systems implementations, global audit recommendations for SEC registrants, etc.) at times during the last 3 years things have been sink or sink lower credit wise and the ID theft didn't help (apparently, I bought a car in GA and own some property in TX).

With a short sale, the basic explanation of the process is that the homeowner contacts their lender and the lender reviews the homeowner’s specific situation (financials, hardship and reason they are seeking to sell the property, etc.).
