Any market data tools out there?

[Bob Jaeger]

Hi Gang!

I'm looking for websites or other places I can find real time data on real estate sales so I can make solid decisions on where to focus my investing efforts.  Specifically, I'd like to focus on Days on Market less, Months of Inventory and Median Price to back into which towns near me.  I realize I could ask my realtor to do this for me but I'd like to know if its out there somewhere I could do it myself.

Also, what other sources or data points do you look at such as population and job growth do you look at when considering where to invest and more importantly where do you get the data?

Thanks in advance for your help!!
