These are so basic and yet they are FUNDAMENTAL if you are going to be successful as a passive investor.  

Are there any specific resources you like using for finding these characteristics/fundamentals?

Well, you look for fundamental factors and trends that do not fluctuate quickly and are not dependent on the economy.1.  

It has been this way for over 50 years and I see nothing fundamentally to change this. 

Denver, LA, San Fran, Phoenix, etc. are all "hot" markets and with great market fundamentals.

There is some great fundamental nuggets in the Rich Dad series.I am much like you. 

Do you have additional areas where you believe systems are fundamental?

These politicians are idiots and I fundamentally disagree with the red tape beuracracy they put on entrepreneurs and investors.That all being said as a value investor who's in this for the long haul I can adapt and adjust to anything they throw at me. 

You must maintain good investing principles as with investing anywhere, but the fundamentals and makeup of this market is very solid and offers multiple opportunities.

Fundamentally I think that most people misuse metrics because they annualize them when the assumptions about how the money will work are dissimilar from project to project.
