Both have well respected schools - and the quality of schools and access to highways/NYC are among top deciding factors for most of our Basking Ridge has 2 train stations and bus service to the city - Warren does not. Basking Ridge does have lots of parks, but we have very nice facilities in downtown Warren as well as sports fields elsewhere in town.
Two great towns - recommend you look at them - and the inventory availalbe to you in parallel
Unwavering Commitment to Service, Unsurpassed Results
The differences between Warren and Basking Ridge are subtle. As Pat said below, you really can't go wrong with either choice, I think it's a matter of preference. Warren is a regional school district - some prefer the township district format. Basking Ridge had a train station, Warren does not. Basking Ridge has a quaint downtown area - Warren doesn't; but Warren offers a larger selection of shops and restaurants.
Some stats for each town as of today according to the MLS - in your question it isn't clear which town you are saying isn't moving:
Basking Ridge: 159 available listings, 36 sales in the last 30 days (absorption rate: 4.4 months); there are 12 properties in attorney review.
Warren: 128 available listings, 19 sales in the last 30 days (absorption rate: 6.7 months); there are 7 properties in attorney review.
I don't think you need to limit yourself to one town - - go see some homes in Warren - - you will know if it's right for you.
