Waterloo’s Zillow ZHVI typical home value is $149,410, while Zillow ZORI typical observed market rent is $898 a month. That produces a 7.2% gross yield—annual ZORI divided by ZHVI—before every operating cost, vacancy loss and financing. The typical value is 2.6x ACS median household income, and annual ZORI equals 18.8% of that income. This is an affordability and revenue frame, not a net-return measure or a forecast.
Citywide, Waterloo has 32,143 housing units, and 8.9% of all units are vacant; renters occupy 37.9% of occupied units. This tenure and vacancy profile describes the citywide stock, not the availability or leasing prospects of a subject property. ACS surveyed occupied housing reports a $152,600 median owner-reported home value and $923 median gross rent, including contract rent plus selected utilities. Those ACS measures differ in period and construction from Zillow’s typical value and observed market rent and should not be averaged.
Single-family homes are 73.3% of city stock, and large multifamily units are 6.4%, a structure mix that does not identify purchasable inventory. Among city renters, 45.4% pay at least 30% of income toward gross rent, indicating affordability pressure without proving capacity for higher rents. Of vacant units, 27.2% are for rent; this reason share does not measure available investment inventory. Population is 67,008, down 1.3% between overlapping ACS five-year vintages; the comparison is neither annualized nor a five-year event count and may reflect boundary changes. Median household income is $57,480, poverty is 16.6% and unemployment is 5.3%. These facts cannot predict property lease-up.
In Black Hawk County, county listings had a median 50 days on market, and the county price-reduced share was 14.8%, offering negotiation context but not a city liquidity measure. In the broader Waterloo metro, metro employment fell 2.2% year over year while metro months of supply was 1.8, pairing a demand caution with current supply context without describing Waterloo alone. The national 30-year mortgage rate was 6.66%, a national financing benchmark rather than a quote for a Waterloo borrower or property.
Keep underwriting property-specific. Verify unit-level rent comparables, lease terms, concessions, payment history, turnover and downtime; inspect systems and deferred maintenance; and budget immediate work and reserves. Obtain the tax bill, assessment status, insurance and hazard quotes, utility responsibility, management cost and financing terms. Confirm title, zoning, permitted use and compliance, then stress cash flow for lower rent, higher vacancy and larger repairs instead of relying on gross yield.
