What are best tools/ analytic resources for analyzing deals?

[Susan O.]

I'm looking for OOS properties. Some areas I don't know much about.  

What are some suggested tools. I've used City-Data forums also I use crime maps sometimes but i feel that it's not very accurate in depicting things

Is there a aggregated site that pulls census data/ real estate sales etc and has a lot of analytics for searching markets?

I was wondering about heat maps that show good and bad neighborhoods as well?  There's some things like Neighborhoodscout but you have to pay and i've never actually used
