Waukesha County

Waukesha County sits firmly at the appreciation end of the spectrum, and the numbers leave little ambiguity about that. The median home price of $502,911 against a median rent of $1,870 produces a gross rent-to-price ratio of just 0.0446, one of the thinner yields you will find in Wisconsin. The cap rate at a modeled purchase price works out to 2.9%, and the cash-on-cash return at 20% down, a 6.85% rate, and estimated expenses comes to negative 14.74%, with monthly cash flow running roughly negative $1,421. That is not a rounding error; it is the structural reality of a high-price, modest-rent market. On the appreciation side, the county earns an 89 out of 100 score, and home prices grew 6.02% year over year, which is the engine this market actually runs on. Its overall score of 51 and a national percentile rank of 27 out of 1,000 counties reflect that the appreciation upside does not rescue the investment-grade cash-flow picture for most underwriting scenarios.

The investor this county suits is someone specifically seeking price appreciation and is comfortable carrying a negative monthly position, either through cross-collateralization with other cash-flowing assets or via a longer hold thesis where equity growth covers the carry. A value-add operator who can meaningfully push rents above the $1,870 median would improve the picture at the margins, but even a 15% rent premium still leaves you well below breakeven on cash flow given the mortgage obligation of $2,636 per month on a standard 20% down structure. A pure cash-flow buyer has no real business here. The affordability index of 28 and affordability score of 28 out of 100 confirm that both owner-occupants and tenants are stretched, which limits organic rent growth and keeps the renter pool somewhat constrained relative to the price base.

Waukesha County's position as the affluent western suburb of Milwaukee anchors its rental demand in a way that raw county-level data does not fully capture. The county's population of 407,290 and its consistent home price trajectory reflect a market that attracts higher-income households priced out of ownership, generating demand for higher-end single-family rentals rather than entry-level units. That dynamic supports the $1,870 median rent even in the face of thin yields, but it also means that your tenant base has options and that vacancy on poorly positioned or deferred-maintenance product can be sharp.

The tax and insurance carry in Waukesha deserves its own line on your underwrite. Using the state-average effective property tax rate of 1.85%, annual property taxes on a $502,911 purchase run approximately $9,304, and annual insurance adds another $1,157, for a combined monthly tax and insurance burden of $872. At 1.85%, Wisconsin's state-average rate is high enough to matter materially in a market where the gross yield is already thin, and it is already embedded in the negative cash-flow figure cited above. Critically, that 1.85% is a state-average estimate from the Tax Foundation's 2024 data; actual county and township assessments in Waukesha can deviate from that figure, so pull parcel-level tax history on any specific target before closing. This is not a market where you can afford to be approximate about carry costs.

The concentration risk worth naming is price sensitivity. At a $502,911 median and a 2.9% cap rate, valuation is almost entirely a function of continued appreciation and buyer demand, not income support. If rates stay elevated or local employment softens, there is very little income cushion to hold values. A stability score of 50 out of 100 reflects that this is not a recession-resistant cash-flow fortress. Demographic risk is relatively contained given the county's population base and suburban positioning, but regulatory exposure around any future rent stabilization at the state or municipal level would hit this market harder than lower-rent markets simply because the income figures here are larger in absolute dollars.

Against its comparison set, Waukesha is the most expensive market listed and the lowest-scoring neighbor by overall rank, despite having the second-highest appreciation score in context. La Crosse County offers a rent-to-price ratio of 0.0489 on a $314,821 median with an overall score of 54, making it a meaningfully more favorable cash-flow entry. Eau Claire County comes in at a $309,357 median with an overall score of 54 and a rent-to-price ratio essentially matching Waukesha's at 0.0447, but at roughly 60% of the purchase price. Ozaukee County, at $470,334 and an overall score of 55, is the closest neighbor in character and price, and its slightly better rent-to-price ratio of 0.0454 and higher overall score suggest it may offer a marginally more balanced profile for investors who still want Milwaukee-metro exposure without going fully into Waukesha's price tier. Choose Waukesha specifically when your thesis is price appreciation in the Milwaukee suburban corridor, you have the balance sheet to carry negative cash flow, and you believe the county's affluent demographic supports long-term equity accumulation that the income statement alone cannot justify.
