I got into the podcast about a month ago and would listen to 3-4 per day while painting the stucco at my rental, great motivator, but needless to say I chewed thru a months worth of data in a couple days.

I don't think NAR/CAR realized they back-doored themselves when they started providing data to third party sites.

I like how the data is laid out. 

If it feels right and you did your do diligence and are comfortable with your data then make the deal.

Sites like realtor.com aggregrate the data.

I'm curious as to why you would make this statement "But the real problem comes when Mexico and Guatemala get it and they don't have the ability to contain it"According to the World Health Organization director: "During the notorious swine flu pandemic, Mexico "gave the world a model of rapid and transparent reporting, aggressive control measures, and generous sharing of data and samples".

It would be great for us to learn and try to extrapolate the data. 

I am trying to build application to pull property information and make decisions based on the data available for the house, neighborhood, properties sold around the same are ect….What is the best fit company/API which can provide API data (XML/Jason) which does the following?

City-Data, Neighborhood Scout and Rentometer are other sites I look at.

Awesome post Jay,Getting some serious heat on it :)As you mentioned, there are many areas in the Midwest that offer a "war zone" entry price, but are actually very very solid neighborhoods.Actually just moved into one lol.Wouldn't rebuilding create even more jobs?
