My advice - use your cash to learn how to joint-venture on a deal with someone who has experience.

With your experience and a clear goal to build wealth and transition into multifamily commercial properties, you're on the right path.

I’m sharing my experience so others can avoid the same issue. 

That sounds like a strategy that some of the YouTube gurus are teaching to wannabe investors with no money or experience and that is going to end up with a lot of deals going sideways as these buyers will probably fail because overpaying is obviously a bad strategy to begin with. 

I admire your experience !

Does anyone have any experience with these locations?

The diligence varies by county, but my experience has been that they check very thoroughly.

(Note: I'm not a lawyer, but this is my understanding based on my experience)  A human being will need to sign on behalf of the LLC and that human will need to have the authority to sign. 

Many flippers are open to sharing their experience.

Thanks for sharing your experience.
