Waukesha County is very desirable for investors who prefer to keep their distance from the City of Milwaukee and the greater Milwaukee County area. Next to that, the main selling point is Taxes! Property taxes drop significantly once you leave Milwaukee County. As with all metropolitan areas, suburbs become more desirable because they have better or more desirable schools. Better schools are also associated with higher prices and higher rents. Waukesha County, however, does not have the sheer amount of product as its urban neighbor. You can expect strong appreciation in Waukesha County.
