Every person has a different idea of where they see themselves living and raising a family. One must see if the school systems meet their needs, how the places of worship are, if thats important to them and how each area within a community may differ as well. Get a buyers agent to drive you around, view the different schools, look at the mcas scores, see what % graduate and go onto college, view different different areas within a community and see if it is as you imagine and want. Read information on line about the community, speak to the local police dept, to see if it is a safe area you are considering. Lastly speak to your future neighbors.
Some want to be close to their employment, transportation, friends, family ect. We are very fortunate in that there are so many great places in Massachusetts to raise a family.
