Updated 2026 · Based on median market data for Fond du Lac, WI
The median monthly rent in Fond du Lac, WI is $1,070, translating to $12,840 in annual gross rental income per unit. The rent-to-price ratio is 0.38% — well below the 1% rule, making pure cash flow investing challenging at median prices and requiring investors to target below-median purchases or value-add strategies. For context, a 0.38% rent-to-price ratio means that for every $100,000 invested in property, you collect approximately $382/mo in gross rent. The gross rent multiplier of 21.8x means it takes 21.8 years of gross rent to equal the purchase price — a high ratio that reflects price appreciation outpacing rent growth.
Renters in Fond du Lac spend approximately 24% of the local median household income ($53,700) on rent. This is well below the 30% threshold, suggesting significant headroom for rent increases. The 30% affordability ceiling puts maximum supportable rent at approximately $1,343/mo — a full $273/mo above the current median of $1,070. This gap represents real upside for landlords who invest in property upgrades that justify premium rents.
The vacancy rate in Fond du Lac is 5.5%. This is a healthy vacancy rate that indicates balanced supply and demand. You should be able to find quality tenants without extended vacancies, though expect normal turnover periods of 2-4 weeks between tenants. Budget for one month of vacancy per year in your underwriting to be conservative. Population growth of 0.5% annually provides stable demand.
Fond du Lac's GRM (price divided by annual rent) is 21.8x. A GRM above 16x means the property is expensive relative to its income. Investors here are typically betting on appreciation rather than current cash flow, which adds risk if the appreciation thesis does not materialize. For comparison, the national average GRM for investment-grade rentals is approximately 13-15x. To beat Fond du Lac's median GRM, target properties where you can achieve rents above $1,070 through renovations, better marketing, or targeting underserved tenant segments — or buy at a discount to the $280,000 median price. Every point lower on GRM translates to roughly 0.5-0.8% improvement in your cap rate.
At the median rent of $1,070/mo, a single-family rental in Fond du Lac generates approximately $12,840 in gross annual income. After accounting for 5.5% vacancy ($706 lost), property taxes of $5,264, insurance (~$1,120), and maintenance (~$1,120), the estimated NOI is $4,630 per year, or $386/mo. Adding an 8% management fee ($1,027/yr) reduces investor cash flow further. Before debt service, you are looking at approximately $3,603/yr in landlord net income. Whether this is attractive depends on your total capital invested — at a $56,000 down payment, the unlevered yield on equity from NOI alone is 8.3%.
Rent growth in Fond du Lac is driven by the interplay of population growth (0.5%), income growth, and housing supply constraints. With 0.5% population growth, organic rent growth will be slower — roughly 1.5% annually, taking rents from $1,070 to $1,153 over 5 years. The affordability headroom of $273/mo between current rents and the 30% income threshold provides substantial room for rent increases without pushing tenants into financial stress.
The median income of $53,700 supports a mixed tenant base of young professionals, small families, and long-term renters. In a smaller market of 50,000 residents, word-of-mouth and local listing platforms may be more effective than national sites for finding tenants.
Fond du Lac is a smaller market where professional PM options may be limited. Fees can run 10-12% of rent, and the quality of available managers varies widely. At $1,070/mo, management costs roughly $118/mo. Self-management makes sense if you are local, have fewer than 5 units, and the rent level justifies your time — at $1,070/mo, self-management of a small portfolio saves meaningful dollars but professional management becomes economical at 3-4 units.
