I have lived in Edison since 1983 and both my kids went through the public school system. The Edison schools are very good.
So it will really depends on what you are looking for as far as size of the home, price range etc. The "north" side of Edison (zip 08820) is typically a bit pricier than the south side (zips 08817 and 08837), though there are homes in all price ranges/styles throughout the town.
Give me a call for a no obligation discussion of what you are looking for. I am sure I can help you find a home in the area. 908-675-0167
