Next you should know your affordability. If you haven't already contact a lender and get prequalified. Once you know your affordability you can research the value of homes located in the area you circled on the map. Find areas that offer you a good selection of homes in your price range. This may help you zero in on one to three school districts.
Once you have done this now you can do a focused neighborhood search for things that are important to you. The internet is loaded with information. However, through your job you may know people who already live in these areas. Ask them your questions. Also, drive through these areas at different times of day and simply observe. Stop in to stores buy a soda and ask some questions. Consider making appointment to visit the schools. Stopping by a police station may be helpful as well.
Once you do these things it will probably become very clear where you want to live. Good luck.
