West Allis duplexes and multi-family investment properties are plentiful. One of Milwaukee’s largest suburbs, West Allis was settled in the 1830s and grew up around the factories that gave it its name; it was incorporated as a city in 1906. Centrally located, residents are a short drive from anywhere in metro Milwaukee. The city is home to Wisconsin State Fair Park, the Milwaukee Mile, the Pettit National Ice Center (the U.S. Olympic speed skating training facility) and the West Allis Farmers Market, one of the largest in the state, which runs through the warmer months.
West Allis offers affordable homes with a mix of single-family houses, bungalows and duplexes, plus lots of shopping and dining along Greenfield Avenue and Highway 100. Many neighborhoods are filled with well-maintained duplexes, and besides being attractive investment properties, West Allis duplexes for sale are popular with first-time homebuyers. It is one of the area’s most active markets for a “live in one unit, rent the other” purchase.
