That's a pretty wealthy area.
Around here, the wealthiest areas are filled with mansions instead of condos, varying in age from 100+ years old to built 5 years ago. Around Lake Calhoun and the other 4 lakes in South Minneapolis is where one of these mansion pockets is, while all around the shores of Lake Minnetonka in the western suburbs is one huge concentration of them, most notably the suburb of Orono, where many execs of the Fortune 500 companies in the area reside. Mansions tend to be built by large lakes around here.
