Polk County presents a carry-focused, not cleanly defensive underwriting case. Zillow’s county observation labeled 2026-06 shows median home value growth of 0.7%. FHFA’s annual repeat-transaction index labeled 2025 rose 1.7%; the direction is consistent, but its different vintage and method cannot be blended with Zillow or treated as a dollar value. Investors relying on appreciation or thin cash flow should investigate carefully, especially inland-flood exposure, taxes, and employment softness.
Measured market rent is published: median asking rent is $1,259 per month, up 2.31%, and reported gross yield is 5.32% before costs. HUD’s two-bedroom FMR is $1,318, a payment standard rather than an asking-rent estimate; market rent is 95.5% of it, but FMR cannot replace market-rent evidence. Carrying costs matter: the effective property-tax rate is 1.68% and median annual tax is $4,396. Insurance, repairs, vacancy, management, financing, and capital costs are not supplied, so net yield and debt-service coverage cannot be determined.
Realtor.com’s MLS evidence indicates softer visible listing conditions, not a closed-sale verdict: median listing price fell 3.98%, active listings rose 5.34%, and 20.66% of listings were price-reduced. These may improve negotiating room, but no closed-sale or absorption measure establishes buyer demand. Net migration was positive at 481 households, while the inbound-minus-outbound average AGI gap was negative $3,405, so household count and purchasing power diverge. The annual 2025 QCEW record covers county-located jobs, not resident employment; covered employment weakened even as average weekly wage rose. Investor purchase mortgages were 8.13% of purchases, showing participation but not dominant competition.
The modeled climate loss ratio is 0.09% of building value per year, while inland flood is the dominant hazard; that ratio is not an insurance quote or a property-level flood determination. Next checks are parcel flood maps and elevation, insurance terms and deductibles, leases, operating expenses, financing, and closed-sale comparables. Without them, this county record cannot establish property-specific hazard cost, net cash flow, or whether listing softness translates into an acquisition discount; it also does not establish conditions across the Des Moines metro.
