For a quick reference on neighborhood information I find Zillow to work the most intuitively. As always it is best to consult either a Real Estate Professional or friends and family members who may live in the desired area for more specific information.
Here is a quick link to Zillows Local Information tab. Just input city name or zip code and you are ready to go.
If you would like to see what is on the market you can use my search which pools directly from the current MLS database.
