I've been in commercial real estate since 2013, and in that time I've worn three different hats. I've been a broker, I've been a property manager, and I've been an investor and developer.

Thirteen years is long enough to be wrong about almost everything at least once. I've had a $20,000 HVAC unit die two months after closing. I've pitched 50 lenders on a hotel and had 49 of them tell me no. I wrote a proforma on my first deal that was, and I mean this literally, fiction.

So if you're trying to figure out how to get into commercial real estate investing, this is the stuff I wish somebody had handed me in year one. Five lessons that actually moved the needle, and then the exact playbook I'd run if I woke up tomorrow with no money, no network, and no name.
