My portfolio is diverse.

Still, with a diverse employment base and three colleges inside the city limits, there's a lot to like about the tenant pool depending on your price range and overall strategy. 

Good credit and relationships with investor friendly lenders will serve you well also.If I let you behind our office doors to see our model you would see a very diverse business strategy, we don't rely on just one area of the market, hopefully protecting us if there is a major correction in a specific area. 

I just read this blog post https://www.biggerpockets.com/renewsblog/places-invest-real-estate in which 6 markets were scored across a few categories:- median rent: median value- rent to income- taxes to value- insurance to value- average appreciation- unemployment- crime- population growthA few people commented afterwards and highlight job diversity, % renters, and % vacancies are also important.As far as sites people use, I’ve only heard of city data but I’m not very familiar with that site.

I have only watched and listened to Maverick on webinars and they seem to do it right and they seem to do it in right places and they seem concerned about a diverse community economy.

Lately, I've focused on places as diverse as AL, NH, and DC. 

The best areas are larger cities that are diverse economy and have increasing population and increasing jobs available. 

:O)Not slamming OKC  just stating that the economy there is not quite as strong as some other areas that are a little more diverse.. does not make it a bad rental market. 

But as Brant said above, they are lower risk and safer than mom and pop shops.Strip center's are also a great alternative and as you said, the diversity creates less risk and more opportunity. 

This provides me some diversity but also more risk because I'd have to have funds always available in the IRA to pay for missed rents.3) Buy 2-3 performing notes.
