Hi
I don't know how much you know about the dispersal of money within the state of wisconsin, buy if you want to move up here this is what I've observed.
I'm going to give you some logistics to Wis and the where abouts of, and who's holding all the dough that might need financial planning. It would be good to have a Wisconsin map in front of you or online so you can follow along.
Marinette is a bit north of Green Bay (an hour?) on the Wisconsin/Michigan border separated by the Menomoniee River (i think)
If you look at the map, start at I-43 and go north of Milwaukee County. Next is Ozaukee County. Most of these cities/villages etc are mega-wealthy (Mequon, Thiensville, Cedurburg, Grafton, Newberg, Kohler) Most of the money is generational, older money. Head up to Green Bay and Door Cty. The money is there and so are some very rich football players and old Chicago residents. In Milwaukee Cty, just a few cities are worth investigating -very old money . . . Whitefish Bay, Shorewood, Bayside. And South of Milwaukee include, Greendale, Franklin, Muskego, Oak Creek.) These are areas of "newer" money and only some money, not a lot-its up and coming.
However, your two best bets in the state are Lake Country and the Fox River Valley. If you look at a map and follow I-94 about 25-35 miles west of Milwaukee. Average costs of homes in this area is about half a million. There about 15-20 lakes that are being built around. For the most part this money is from new upper echelon executives who work in Milwaukee, Madison or somewhere in-between. The cities include Hartland, Merton, Oconomowoc, Pewaukee, Nashotah etc. Then there is the Fox Valley cities including Appleton, Oshkosh, Neenah, Menasha. These are all old paper processing mill towns. As paper processing was sent elswhere, printing and advertising plants replaced then, but kept some paper processing going so its a mix of old and new money. This area is built around Lake Winnebago.
Last, there is always Madison–politicians, doctors, research facilities, new technology start-ups, professors, multiple universitie,etc.
Any of these areas would be 4-5 hour drive (or less) to your wife's mother in Marinette. You could even have one office somewhere in the middle and then maybe a satellitte office from your car.
You probably knew most of this stuff but I thought I'd just throw it out there for whatever its worth. Take Care. -Mykal-
