I'm assuming its a greatest hits, plus its kind of fun to listen to how the podcast has evolved over time. 

I learned most of this through podcasts, youtube videos, and other investors sharing their deal analysis sheets with me, but it's important to understand that your spreadsheet is always changing and evolving. 

@Chris Shelton For me it was a matter of personal preference which has evolved as time has passed.

Books can often be written for a period in time and a mentor can evolve and help you evolve as the times change.

Over time the structure evolves and sytems are installed.  

Your strategy should evolve as your personal situation and market situation changes

MA is a particularly complex state and court interpretations of foreclosure statutes evolve. 

I've been working on a project to tap into the evolving tiny house market and have ZERO clue as to what a real estate developer does exactly.

We eased into it by starting with EVOLVE to handle listings and reservations while we handled the rest, then took over the listing/reservations ourselves.

Evolve does that for 10%.
