You really need to understand how your local court archives and manages files. 

Does Washington have an archive of old fire insurance maps that might show the occupancies of structures?

The research means going to either the Archives on Hill Street in downtown LA and or the Recorders office in Norwalk.  

@Cody BarrettI use the CMS system we previously had in-place for my other business, but one should use whatever medium is most comfortable and convenient as you are more likely to stick with it.In the case of electronic communications, it is very easy to archive email and SMS correspondence.   

I think investing in real estate could help us archive this goal.

Serious investors spend the time and money to learn how records are archived in your state and county's public records office. 

So I've watched a pretty good presentation on 'hard money' from Rich Club's webinar archive. 

Perhaps one method to familiarize yourself with various strategies is to check out the podcast archive and sign up for the weekly webinars.

The book teaches you how to not make the common mistakes in building your business and provides you with a framework on how you can successfully grow a business either solo or with a partner.I also suggest going through the back archive of Pod Cast's.
