There is a town not far from where I lived in Central NJ that was basically one big retirement village. Some of our friends and neighbors moved from our neighborhood there. DH and I did not find this town, Monroe, NJ, to be an attractive option for us at all. Taxes are low because there are no schools. Everyone is 55+
One of its communities, Rossmoor, has been around forever. Here is a description. I looked up single family homes in Monroe and they range from low to high for 2BR/2 baths. But again, the whole town has a creepy "Cocoon" vibe to it. Not for me.
