Not a big fan of Zillow myself, but when it comes to preliminary market trend research, they have one of the nicest formats to demonstrate the trends of each particular area for each particular time frame. You can go as wide in both or as narrow and you can personally modify your parameters.
THE CATCH with Zillow - their estimates of values are almost always wrong, because they do not adjust their for condition or foreclosures/short sale properties. Great format with misleading information is as good as any other unreliable source of info. If you are the type who likes to do your homework first, google market stats from the National Association of Realtors.
For more in-depth analysis, you will be better off with a professional advice form a solid, full-time buyerâ€™s agent with research background and/or a stellar performance record. When you are ready for that stage in your home buying process, check out my background and services and call.
Good luck in the meantime,
