I don't know if you are still looking in Madison, but interestingly, the line between north and south seems to be inching north these days. Clearly, you get more for you dollar, the further north you go in terms of house and lot size but even in the 'south', ie. south of Route 80, things vary dramatically neighborhood to neighborhood and in relation to Route 1 and the water. The good news is that either area enjoys a wonderful downtown, great beaches and recreation, and award winning schools.
If you need more information, please contact me. I'd be happy to help, and have lived and worked in Madison for most of the past 26 years.
