Hallmarks of River Hills homes are generous lot sizes and are gracious. With the vast majority of homes built on minimum 5 acre lots, it’s no surprise that most of the housing stock here is priced above $400K. There are two very small older neighborhoods where more modestly priced homes can be found. River Hills is the crème-de-la-crème of Milwaukee County with average home values over $600K. There are no businesses within its borders. There are also no condos nor multi-family dwellings here either.
