I also track statistics in the towns that I am interested in.  

Look at the statistics for San Diego appreciation.  

I'd like to know what are some key market stats that indicate which areas have a good, growing renter population that you all look for before investing in a rental property? Also, where is the best place to get that i...

@Harold Isaacs I look usually just at: http://www.zillow.comYou can find there many statistics for neighborhoods, cities and states.

The city publishes an apartment statistics page, found here: http://www.wichitafallstx.gov/DocumentCenter/View/24175That publication was during the high oil prices of 2014, but also during a regional 5 year severe drought. 

The statistics on violence against Realtors is pretty high.

There are also pockets in the area where appreciation is possible, too.I've never seen the statistics published, but my guess is that there are thousands of own-of-town investors, many of whom are from around the world, invested in the Memphis market.  

MSA stands for Metropolitan Statistical Area, it is essentially the area around a city that is effected by socially and economically by its relationship to that city.

Then the market will adjust where homes in areas that are too risky just can't get insurance so will draw cash only buyers willing to take the risk on their own, and the areas that are statistically safer will become the norm for people needing mortgages, with the benefit of no surprises when/if  something happens as you know your insurance company is required to cover, maybe just a higher deductible.  

I guess I am another statistic who joins BP and disappears.
