I believe 5% is arbitrary or part of their much larger context regarding diversification, as I frequently see figures like 5%-10% used when discussing the maximum amount of your portfolio that should be invested in any one stock, sector, asset, asset class, etc.Another thing to realize as well is that followers of Dave Ramsey and followers of BP seemingly approach saving and investing in very different fashions but both can work and provide growth and financial stability based on the the person and their situation.It's up to us to determine which school of thought, or combination of the two (or the countless others, for that matter) is the best fit for ourselves.

Then look up the following criteria:Unemployment ratesPopulation growthAge range population changes Median rent ratesVacancy ratesPercentage of job sectors (says be careful in areas that have one dominant sector +25% bc if that sector tanks it will most likely have a neg impact on rents)Top employers (same as above)The you take that data and observe the trend over the last 5 years to try and get a good grasp on how that area is trending.

I know how screwed up the system is because I worked for the County in the Investments Dept for two months before deciding this crap wasn't for me and went back to my old job in the private sector. 

Nearly all of my tenants have recently moved to ABQ for jobs in the healthcare sector, government, and movie industry.

What is the likely impact on the largest sector of the US economy?

I've never invested in this sector;  It is a very different business model.
