I've had no luck with their stats or with any of the stuff VRBO posts up there.

Very interesting stats.  

So far, my research shows a good mix of demographics, population, incomes, AND the crime stats seem pretty low... lower than the national average.Anyone investing in Appleton, WI and willing to share your thoughts/experience?   

Any landlord that offers this should have their head examined! 

As @Robin Smith mentioned, for assessing demand I used FurnishedFinder.com/stats; you can see demand data for a given city and some pricing data too.

I would think your insurance agent might have access to some historical information for a specific area as they would want to examine this closely for their underwriting.

Any stats you can provide would be a bonus. 

I am in the process of studying for my licensing exam in the state of Tennessee and plan to work in the Chattanooga area upon completion of the test (which will be quite soon).

Happy to share these stats with you. 

I tend to believe that could be a reasonable stat for the experienced investors, however, I don't know where you even get enough accurate data to formulate anything.
