I hired an IRA-approved valuation company to value that note at that time.

Are there investors here in Texas that have utilized and would recommend banks they hold series LLC accounts with? 

Better hope paint,carpet,advertising, commissions, and utilities don’t cost $600 or you blew your cash flow, it’s zero.

As mentioned have an attorney or title company draft the note and mortgage.

The mortgage company gets paid off first, then in a traditional sale, the rest minus agent fees and utilities and closing costs goes to the seller.

Plumbing company says its the only way to resolve the issue I have.

The insurance company says it’s too much of a fire hazard.

The paralegal was good at interfacing with title and trustee companies.

One thing I think I would do is either hire a professional market research company and/or get a local high school or college marketing class to do market research and surveys to see if there is interest and demand. 

In the real world, most companies with stock prices that drop down that low are more likely to go completely bust, and whatever you invested will just be lost.Regardless of the game's weaknesses, I think overall it was valuable learning experience.
