Ottawa County presents a decision tension: a modestly rising Zillow home value sits beside far slower FHFA index movement and no published market rent. Buyers who need present cash-flow coverage should be cautious; reviewers testing basis and operating costs should investigate further. At Zillow’s 2026-06 county observation, median home value was $142,292, up 1.97% year over year. FHFA’s 2025 repeat-transaction HPI rose 0.54%. It is an index, not a dollar home value, and its distinct vintage and method cannot be averaged with Zillow’s change.
Carrying costs have a measurable tax component: the effective property-tax rate is 0.62%, with median annual tax of $763. The record does not publish market asking rent, so gross yield cannot be computed from this evidence. HUD’s $937 two-bedroom FMR is a payment standard, not an asking-rent estimate, and cannot replace market rent in the calculation. Therefore price and tax can frame basis and carrying costs, but not rent coverage.
On Realtor.com’s MLS listing market, active listings increased 13.70%, adding visible supply; this is asking-market evidence, not closed-sale pricing or proof of demand by itself. QCEW reports 12,885 annual average covered jobs at county workplaces, down 0.38%; it is neither resident employment nor an unemployment reading. Tax-return migration was net positive by 11 households, and arriving movers had average AGI $661 above departing movers, a slight income edge but limited flow evidence. Education and health services was the largest disclosed private supersector, not the whole economy. Investor activity was 17 of 252 purchases, a minority that still warrants competition checks.
Inland flood is the dominant hazard, while modeled climate loss equals 0.27% of building value per year; that is a county-level expected-loss ratio, not a parcel forecast or an insurance quote. Underwriting remains limited by unpublished market rents, leases and vacancy, closed-sale comparables, and parcel flood and insurance costs. Those absences prevent confirmation of yield, all-in carrying cost, and resale liquidity. Next, check rent comps, executed leases, transaction comps, flood mapping, elevation, insurance terms, condition, and tax-assessment detail.
