It's a solid list except for that 1/3 acre thing. That's a pretty big lot in eastern MA, especially inside 128. If you're OK with outside 128 in North Andover, Groton, and other such areas it can be found, but it's going to be an older home. And by older I mean probably late 1800s/early 1900s homes.

Inside 128, with the desire for good school systems, you'll be lucky to find 1/4 acre, most lots of that price range and bedrooms will be 1/10th or less. And age will vary from 1800 to 1950s as far as age. Newer homes will be much higher.
