As to #4, very important consideration. About 25 years ago, one of our parents suddenly passed. We moved back to NJ, and we never looked back. Kids lived near the remaining grandparents who made all the birthday parties, important school events, etc. Family is important.
#6- I alluded to this. Is $4,000-6,000/year worth it if you are making less money, and/or driving back up to NJ several times per year to visit friends, family and go to RU games, etc. Not to us.
As to #7- same for a lot of us who have favorite recreation spots. For me, the mountain biking trails in South Monmouth are superb. Can also bike ride to the beach. Our marina is a few miles away. Life is good here, regardless of others' complaints. Also, like that we can get a good sub, pizza, or any type of meal of various types from a wide variety of restaurants.
