Are you asking about Raritan Borough (Somerset Cty), or Raritan Township (Hunterdon cty) ? One advantage of Raritan Boro is that the prices are better than Bridgewater Township, but they share the same very highly-rated school system. There is a really cute old-fashioned downtown and many places where you could live so close to downtown shops and restaurants (and the train station) that you would not have to use a car all the time. Train commute to NYC is about an hour and a half.
Raritan Township is further from NYC, encompassing the town of Flemington. Also very charming, with a great school system, but rather high taxes. I won't go into it further until you let me know which one you were originally asking about.
Raritan Boro - my partner and I have an ADORABLE and affordable brick townhouse on our website, very convenient location for a commuter, that you might be interested in seeing. You can see it on our website.
Good luck to you and please contact me if I can be of any assistance.
