Your question is one frequently heard by experienced realtors, but not easily answered.
There are a lot of factors to consider i.e commute, price range, ratings of schools, age of children, likes and dislikes in houses etc. etc.
What I suggest is to sit down for a consultation with a local realtor who knows the area, and go over these and any other questions. Give the realtor all the information you can. Than he/she can do a search for you including the criteria you have come up with, and than you can both begin looking at some of these homes together.
My office is in Parsippany, and Denville and Parsippany are two areas we deal with every day.
Please feel free to give me a call and I would be happy to sit down with you and get you started. I'll even throw in a free cup of coffee. My cell phone is the best way to reach me, as I am in and out of the office. 201-618-0309
