Grand Rapids’ current Zillow ZHVI is $313,551 and ZORI is $1,627 per month. The pairing implies a 6.2% gross yield before operating costs, financing and capital work. Against ACS median household income, the Zillow value is 4.54x income and annualized Zillow rent is 28.2% of income. These citywide typicals frame price and rent, not any listing’s economics.
Citywide vacancy is 5.5%, the renter share among occupied units is 46.0%, and the median year built is 1953. ACS reports an owner-reported $244,500 median home value and $1,266 median monthly gross rent. ACS describes surveyed occupied housing, with gross rent including contract rent and selected utilities; Zillow instead tracks a typical value and observed market rent for a different measure and period. The series are not interchangeable and should not be averaged.
Direct city depth shows 49.1% of renter households spend at least 30% of income on rent. Single-family units are 61.5% of housing, versus 14.1% in large multifamily structures. Among vacant units, 36.5% are classified for rent; this survey reason share is not available investment inventory. Population increased 0.1% between overlapping ACS vintages, a change that should not be annualized and may reflect boundaries. Median household income is $69,108, while poverty is 16.9% and unemployment is 5.2%; these describe demand constraints, not tenant quality, future rent growth or leasing speed.
Kent County listings had a median 32 days on market and 16.1% with price reductions, while the Kent County property-tax rate was 1.11%; these county measures do not set city or parcel outcomes. The broader Grand Rapids metro had employment down 0.3% year over year and 1.4 months of supply; neither metro measure describes city rentals. Nationally, the Freddie Mac 30-year mortgage rate was 6.58%, a financing benchmark rather than a borrower quote.
Underwriting is limited by citywide typicals, overlapping surveys and broader-geography indicators with different denominators. Verify the property’s price, legal units, achievable rent and utility responsibility; obtain parcel taxes, insurance and hazard terms, inspection findings, repair and replacement reserves, vacancy and turnover assumptions, management costs and a loan quote. Recalculate cash flow and yield from property-specific inputs rather than treating city vacancy, ACS burden, or county and metro statistics as guarantees.
