Is there a proper documentation process/legal methodology for closing in escrow that goes along with this?

I'm not sure about the methodology used to arrive at the findings, but based on my own local knowledge of the individual areas, the information was pretty accurate. 

Unfortunately, I have another book I'm working on before those, and I haven't been making as much progress on the other book as I was hoping anyway...While Chris' point above is reasonable (a book won't teach you everything you need to know), the general methodology can be learned from reading about new construction projects. 

Definitely start by reading the Ultimate Beginners Guide http://www.biggerpockets.com/real-estate-investingOnce you have a better understanding of the various methodology of real estate investing, start refining your research to things that interest you. 

I won't be moving until sometime in 2016 so I want to start learning as much as I can now to be in a better position to invest not only here in my back yard but all around the world throughout my travels.My goals for REI: are currently to get my first deal done using the methodology of creative financing by the end of 2015.

The methodology for an appraisal is quite different than what you're doing with this spreadsheet.

The methodology for that study has come under fire.

I'm having a hard time with the S.M.A.R.T. goal setting methodology.

To be able to compare multiple properties (cash-flows) using CAP, the CAP on each property must be calculated using he same methodology to be meaningful.On a building like this you might be better off to compare it to its peers using the Gross Rent Multiplier (GRM) which is the ratio of the price of the property (cash-flow) to the annual gross revenue.

Looking at the apprasials they appear to have used a significiantly different methodology of arriving at appraised value.
