Here is my presentation for MAREI (The Midwestern Association of Real Estate Investors) on everything you could possibly want to know about due diligence. It was given before Covid-19, so that's why there's no discussion of that. But pretty much everything else you need to know is covered. And given how essential due diligence is, you will want to watch this one from beginning to end.
