You may find it helpful to get a Market Insider report. It's free on my website at http://www.movingsouthofboston.com/mimarket/zip/02370/ . Just copy and paste the link.
You'll see that the median price for July is $285,000, median days on market is 92, community information, compare areas, school information. You'll also see a graph showing list to sold price.
I hope this helps.
All the best,
Success! Real Estate
