Perhaps they would entertain it as part of the deal as a cashflowing rental for them?

To my point, that is a very specific type of investing, and obviously the worst of it is being shown for entertainment. 

But no one that stupid is going to ever get to the point where they are entertaining a 100-unit, so there's no point in trying to market to that person, they don't really exist at that scale (and, to they extent that they do, they aren't falling for real estate scams, they are falling for crypto/nft/blockchain/ai [+ next years buzzword, whatever that is] type scams). 

It took a few decades to go from a hype to the backbone of almost everything from commerce to entertainment. 

But if I could actually cashflow and be profitable, I'd certainly be willing to entertain other areas of Hawaii. 

That is certainly worth entertaining.

When people express interest (no pun intended), you should have a package prepared to share out (not right away necessarily - but after you've entertained the topic at a high level) that includes your project experience (past flips) and schedule of real estate (rentals) as well as settlement statements that can back up your purchase price and exit.

Have you entertained restructuring the 2nd you have on the property and increase the loan amount? 

Payroll was significantly higher, entertainment costs, food, utilities...everything was pretty much under budgeted.

If you decide to entertain this, due diligence will involve digging deep into the business financials to understand cashflow, solvency, and liquidity, his personal finances, and searching for any liens or UCCs in place.
