This very credible methodology appears to be doable in every market. 

Thanks for sharing that methodology though.

I dind't drastically change my entire methodology, just became more aggresive and self confident knowing that I could always turn to this site for advice if I felt I was getting in too deep or unsure of my decision making.The biggest benefit I've had from being here is simply reading the forums.

I just think there is more than one way, and it’s a good idea to understand multiple methodologies.

Get your screening methodology in place.   

I love to read and am constantly reading business, marketing, sales, inspiration, methodology, even real estate investing books.These are three books I recommend that I have read in the last 90 days that speak to all different levels of real estate investor and RE business owner.

But not new to "Project Management Methodologies"@Mike Garrett , I completely agree with everything you mentioned.

You don't state your methodology, but in your article your #1 and #2 top appreciation cities are not in the top 100 in size per https://worldpopulationreview.com/us-cities which means you mix and match (IMO) non-comparable cities. 

@Mario BroughtonYou'll find that most to all of these "creative" ideas and methodologies only work when the conditions/situation is correct. 

I'm pretty sure all counties use mass appraisal, so there is hardly a chance that it would use a nonuniform methodology.
