Fond du Lac, WI — Mobile Home Park Investments

Fond du Lac, Wisconsin — “Fondy” to locals — sits at the southern tip of Lake Winnebago in east-central Wisconsin, about 75 miles north of Milwaukee and 55 miles south of Green Bay. As the county seat of Fond du Lac County and a city of approximately 43,000, Fond du Lac is one of Wisconsin’s most important manufacturing hubs, home to major industrial employers whose workforce creates sustained demand for affordable housing. For mobile home park investors targeting Wisconsin’s productive mid-state corridor, Fond du Lac deserves serious consideration.

Fond du Lac Market Overview

Fond du Lac County has a population of approximately 103,000, with the city proper anchoring roughly 42% of that total. The city’s economy is manufacturing-heavy, with several nationally recognized industrial firms headquartered or operating major facilities locally. This manufacturing concentration has historically insulated the local economy from the service-sector volatility that affects tourism-dependent or retail-dominated communities.

Median household income in Fond du Lac County runs approximately $60,000–$65,000 — at or above the Wisconsin state median. However, entry-level and production-floor positions often fall in the $35,000–$50,000 range, placing many workers in the income bracket that manufactured housing most effectively serves.

Why Fond du Lac for Manufactured Housing Investment

• Manufacturing workforce demand: Production workers at Mercury Marine, Stellantis, and other major employers represent the core demographic for manufactured housing — steady incomes that make lot rent highly affordable.
• Below-market rents vs. Milwaukee: Lot rents in Fond du Lac are meaningfully lower than Milwaukee MSA parks, creating acquisition opportunities at cap rates difficult to achieve closer to Milwaukee.
• Limited apartment supply growth: Fond du Lac has seen minimal class-A multifamily development, reducing competition for the workforce renter segment.
• Lake Winnebago corridor: Seasonal and retiree populations add a secondary demand layer, particularly for park-model units near the lake.

Local Lot Rent Data and Trends

• 2015: ~$275/month
• 2017: ~$305/month
• 2019: ~$335/month
• 2021: ~$360/month
• 2023: ~$390/month
• 2025: ~$425/month (estimated)

These rents remain attractive relative to Fond du Lac’s manufacturing wage base. An employee earning $20–$24/hour grosses $41,000–$50,000 annually, making a $425 lot rent approximately 10–12% of gross income — one of the more compelling affordability ratios in the Wisconsin mid-state market.

Zoning and Permitting Landscape

Fond du Lac’s zoning ordinance designates mobile home parks as a permitted use in specific residential and mixed-use zones, consistent with Wisconsin’s Chapter 66 manufactured housing provisions. The city and county operate separate zoning jurisdictions. Wisconsin prohibits municipalities from outright banning manufactured housing, but local standards on minimum lot size, setbacks, and site improvements apply. No rent control exists in Wisconsin.

Infrastructure: Water and Sewer Access

Fond du Lac operates a well-developed municipal water system drawing from Lake Winnebago and groundwater sources, along with a municipal wastewater treatment facility. City-limit parks generally have full municipal water and sewer connections. Rural Fond du Lac County parks may use private well and septic, requiring careful due diligence on system condition and capacity.
