I am a local Real Estate that Handles that Market. Please let me know if I can be of assistance.

you could check zillow.com and they have prices of sold homes.

A real estate agent should be able to pull the entire MLS listings that have sold on your behalf. . If you work positively with a real estate agent I am assured solutions to all of your questions could be resolved. http://www.lynn911.com http://www.homes-for-sale-dallas.com

Don't know that it will give you stats for the past year, but you can order a market snapshot off the homepage of my website which will give you active as well as closed properties. Just don't know how far back it will let you go. Might just be 6 months. It's free and extremely informative, and it will update you monthly, too!

Hire a Real Estate Agent...that's what we do!
