Clinton County’s underwriting tension is that a reported 5.11% gross yield against a $260,967 median home value and $1,112 median asking rent is only a pre-expense screen. Visible listing-market friction, carrying costs, and limited migration require deal-specific verification. The county merits investigation by investors able to confirm rent and flood exposure parcel by parcel; buyers needing rapid resale liquidity or relying on broad county appreciation should be cautious.
The 0.93% effective property-tax rate is a recurring carrying cost, but net yield cannot be calculated because operating, insurance, and financing expenses are not published. HUD two-bedroom FMR is a payment standard, not an estimate of asking rent, and cannot substitute for measured market rent in yield. Zillow’s county value rose 4.13% in 2026-06, while FHFA’s repeat-transaction HPI increased 8.31% in 2025. They point in the same direction but use different methods and labeled periods, so they cannot be averaged or treated as one appreciation interval.
Realtor.com MLS listing-market evidence shows active listings rose 47.01% year over year, median marketing time was 49 days, and 20.44% of listings had price reductions. These are visible asking-market supply and seller-concession measures, not closed-sale prices or proof of buyer demand. Tax-return migration showed a net outflow of 8 households, with incoming average AGI $66 below outgoing average AGI; this does not establish tenant demand. The investor measure places non-occupant purchase mortgages at 4.53% of 486 purchases, indicating participation rather than dominance in recorded purchases.
Risk limits remain material. Modeled climate loss equals 0.08% of building value per year and is consistent with inland flood as the dominant hazard; it is modeled loss, not a parcel-specific flood determination. QCEW annual covered employment at county workplaces declined 0.53% in 2025; it is neither resident employment nor an unemployment measure. Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. Missing property condition, insurance and flood-zone quotes, lease and rent rolls, sale comparables, vacancy, and financing terms prevent a net-yield, resilient carrying-cost, or exit-liquidity conclusion.
