Waukesha County, WI

Waukesha County presents a valuation-versus-income tension: its published yield is modest against a rising county price base, so cash-flow-focused buyers should be cautious while buyers able to test property-level income and flood cost should investigate. Zillow’s county observation for 2026-06 puts the median home value at $512,253, up 5.91% year over year. FHFA’s 2025 repeat-transaction HPI rose 5.36% annually. That separately dated index supports Zillow’s direction, but is neither a home value nor a rate that can be blended with Zillow.

Median asking rent is $1,768 per month, rising 3.48%, and the supplied gross yield is 4.14% before costs. This is measured market rent; HUD’s two-bedroom FMR is a payment standard, not a rent estimate or a yield input. An effective property-tax rate of 1.14% is a material carrying-cost screen against that gross-income measure. No operating expenses, insurance, vacancy, financing terms, or property-level rent are published, so net yield and cash flow cannot be computed.

Listing-market and buyer evidence calls for restraint in reading demand. Realtor.com’s active MLS listings numbered 1,102 and were up 4.70%; 10.91% had price reductions. These are visible asking-market supply and seller concessions, not closed-sale prices or proof of buyer demand. QCEW annual covered employment at county workplaces grew 0.27%, rather than measuring residents or unemployment. Tax-return migration was net positive by 342 households, although average income of inbound movers was $3,636 below that of outbound movers. The supplied investor measure reports 197 investor purchase mortgages against 4,468 total purchases, or 4.41%.

Inland flood is the dominant stated hazard, and modeled climate loss equals 0.09% of building value per year; that county-level ratio cannot identify a parcel’s flood exposure or premium. Missing flood-zone and elevation records, insurance quotes, condition, lease terms, closed-sale comparables, and submarket vacancy data prevent property-level pricing, net-income, and hazard conclusions. Those checks determine whether county-level rent, tax, supply, and climate signals apply to a specific asset.
