Sioux Falls’ supplied Zillow measures put the typical city home value at $336,151 and typical observed monthly market rent at $1,327. That pairing implies a 4.74% gross yield before every operating cost, debt service and acquisition expense. The value equals 4.42x ACS median household income, while annualized Zillow rent equals 20.96% of that income. This is a screening frame for affordability and top-line revenue, not a property return or a forecast.
The city has 90,271 housing units, with a 4.74% citywide vacancy rate and renters occupying 40.45% of occupied units. ACS reports a $292,400 median value for surveyed owner-occupied housing and $1,035 median gross rent for surveyed renter-occupied housing, including selected utilities. Those ACS measures describe occupied housing and differ in concept and period from Zillow’s typical value and observed market rent; combining or averaging them would obscure the underwriting baseline.
Among city renters for whom burden is measured, 40.72% spend at least 30% of income on gross rent. Single-family homes account for 60.56% of city housing units, while large multifamily buildings account for 17.64%; neither share measures purchasable inventory. Of vacant units, 46.72% are classified as for rent, a survey reason rather than proof of units currently competing for tenants. Population was 13.75% higher across the overlapping ACS vintages, subject to possible boundary changes. Median household income is $75,970, poverty is 9.62%, and unemployment is 2.53%; these describe city demand capacity and constraints, not causation or property-level tenant quality.
In Lincoln County, county listings show a 50-day median market time; this county measure does not describe the city alone. In Minnehaha County, county listings show a 42-day median market time; this county measure must remain separate from Lincoln County. The broader Sioux Falls metro has 2.2 months of supply and 0.34% job growth; both metro figures provide market context rather than city measurements. The national Freddie Mac rate for a thirty-year mortgage is 6.58%, a national financing benchmark rather than a local borrowing quote.
The central limitation is that every headline measure is aggregated: Zillow is citywide, ACS is surveyed city context, and the wider records use different geographies and denominators. Underwriting should therefore replace the screening yield with a property-specific rent roll and expense model. Verify attainable rent and concessions, purchase terms, taxes, insurance and hazard exposure, utilities, management, maintenance, capital needs, vacancy assumptions, financing, title, inspection findings and legal use. Compare the subject only with genuinely comparable properties; citywide tenure, stock and vacancy facts cannot establish lease-up speed.
