I have a service called Listingbook which I offer to my clients - it allows you to search via school zones, zip codes, you can draw out a map of the area you are looking within. It updates from MLS every 15 minutes so you have fully updated information almost as fast as I do in my Realtor mls.
If you would like me to send you an inivtation to use it, send me an email.
You use and search, and then just let me know when you have a property you are interested in or want more information- and I'll be happy to get any additional information needed. I live in the old northeast - this is a fast moving area, lots of activity!
Good luck in your search!
