There are many good options, I would recommend Hingham to be considered(depending where you are a 20-30 min drive into Boston). Hingham may have everything you are looking for and more. There is Nantasket beach very close and a popular summering area, more than a couple private schools(which most have above average test scores or higher, I spoke with a student at one particular girls high school and she gave me the just that it is the school for girls who like sports and want to be academically challenged, in her words "girls that come from here say college is easy compared to high school", I know elementary is where your children are at now, but I always consider the future. And they do have some nice private elementary schools as well; if they're into music the South Shore Conservatory is also in Higham). Your budget is on target for this area getting something very nice, even with a pool. They have a good amount of functions like a 'family fun day' etc. And you might even consider what was voted as "one of the most beautiful streets in America", Main St (I grew up in So Cal and visited family often in LA, and I have to say it is quite comparable to the nicest streets there, maybe even a little better because of the sidewalks being set so far back from the road), there are some homes listed currently on this street that fall within your budget. This is an excellent time to buy in your price range, you may get more than you thought. I would highly recommend taking a look here in your search. There are many towns that could be great for you and your family(Cambridge, was recently voted as the safest town in the US on Yahoo, and they too offer some very nice amenities that you may want to consider, not to mention it is right next to Boston), I wish you the best of luck and hope you find a home that you love. If you have any questions or want furthur insight, please don't hesitate contacting me.
