Mackinac County presents a valuation-confirmation problem rather than a straightforward momentum case. Buyers relying on appreciation should investigate the mismatch: Zillow’s county observation labeled 2026-06 reports a 7.54% year-over-year gain, whereas FHFA’s 2025 repeat-transaction HPI declined 6.09% year over year after a 64.74% cumulative five-year increase. These are different methods and vintages: FHFA is an index, not a home value, and neither measure establishes a sale price. Caution is warranted until property-level sales and condition data show which signal applies to the target.
Housing economics cannot yet support a yield screen. Median market asking rent is not published, so gross yield cannot be computed. HUD’s $1,023 two-bedroom Fair Market Rent is a payment standard, not an estimate of asking rent, and must not be substituted. Carrying costs still require attention: the effective property-tax rate is 1.07%, with median annual tax of $1,863. Underwrite actual rents, taxes, insurance and operating costs by property; the record supplies no insurance cost, vacancy, expense, or financing evidence.
Realtor.com’s MLS listing-market evidence points to more visible supply and some concession risk, not closed-sale demand. Active listings numbered 92, up 30.5% year over year; median marketing time was 38 days and 6.08% of listings had reductions. Tax-return households moving in numbered 384 against 394 moving out, while in-mover average AGI was lower than out-mover average AGI. Only 2 of 72 reported purchases were investor purchases, indicating limited reported investor participation; it does not establish cash-buyer activity or buyer demand.
Risk limits remain property-specific. Inland flood is the dominant hazard, and the published modeled annual climate-loss ratio cannot be treated as a property-level dollar-loss estimate; flood zone, elevation, insurance quote, deductible and mitigation history are absent. QCEW annual data cover workplaces in the county, not resident employment; they show employment declining and average weekly wages rising, while leisure and hospitality is the largest disclosed private supersector rather than the whole economy. Obtain comparable closed sales, market-rent and lease data, tax bills, insurance and flood records; without them, price support, yield and resilience cannot be concluded.
