I also see many people buy homes in these communities and then send their children to private schools, which we are fortunate to have many excellent ones close by as well.
Value is in the eye of the beholder, some people find main streets attractive others want lots of land.
Change is good, but Newton still has excellent schools, transportation, and a great commuting location no matter where you are headed.
All towns have or will have to have overrides in order to maintain the quality of the community, from education, infrastructure, police and fire departments. All of which are excellent in Newton and the taxes are a bargain compared to many other municipalities that one may consider.
Fortunately Newton also has a broader tax base than most, as it has some of the countries most desired Malls, two colleges, many office building and parks.
Newton also has had one of the most stable home values in the Country, year in year out. It is an excellent time to buy with these below market interest rates, which are allowing many to get into this community that may not of been able to years ago.
It is not for everyone, and depending on what is important to your perceived values there are many other excellent communities.

I have installed good windows and doors and do not hear the noise from Comm ave.
Also End unit townhouses (2259 and 2269) are further away from Comm ave than other units.
Overall, I think Chatham Village Complex offers a great value. You are right next to Auburndale Park, and close to both major highways (90 and 95). Burr and Williams are some of the best elementary schools in Newton. I wouldn't worry that much about resale values. Although realtors may have a better answer.
