I like their podcast, but the BP thread about their turnkey approach/methodology was definitely a contested hot topic!

There are so many ways to make (and lose) money that it really comes down to simply your investment methodology (appreciation, value investing, cash flow, tax planning, etc.), your investment vehicle (REI, stocks, business ownership, etc.), and your ability to execute (can you follow your objective and succeed). 

Additionally, in talking with numerous assessors, they do not agree on the methodology to be used in calculating FMV.  

My answer is.....let me give you the methodology for determining the cost. 

Lying under a sink wrestling with getting ancient faucets loose is really getting old. 

My goals are to first learn the methodologies that have proven to benefit investors in the two Sarpy and Douglas county regions and position myself to have more options in the future when opportunities to diversify my portfolio are discovered.I am looking forward to mingling with all of you both in-person and via the online community.

Valuation methodology is completely different for MF (5 units or greater) vs SF and scale is a close complement as @Ivan Barratt notes. 

@Ian Walsh I concur, human element and broad-stroke analysis is the best methodology, but I learned from running my own business for 25 years, it is best to work on your business instead of in your business. 

@Erik Nordgaard appraisal methodologies don't really vary my market.

A buddy walking with a cell phone is not going to know if roof is good, electric panel is ancient, if the foundation is sinking, you may need to go there when you do not have the tools in play.
