Mifflin County presents a price-momentum-versus-underwriting gap: buyers seeking appreciation exposure should investigate rent, flood insurance and listing competition, while income-focused buyers should be cautious. Zillow’s June 2026 county median home value was $199,727, up 7.77% year over year. FHFA’s separate annual 2025 repeat-transaction HPI rose 10.47% year over year and 59.89% over five years. These distinct methods and vintages confirm direction, not one comparable growth rate or a home-value estimate.
Housing economics cannot turn the stated home value into a gross-yield conclusion: market asking rent is not published, so gross yield cannot be calculated. HUD’s $973 two-bedroom FMR is a payment standard, not market rent, and cannot substitute. The effective property-tax rate is 1.45%, and median annual tax is $2,266. These are carrying-cost inputs, but parcel assessments, exemptions, insurance and actual taxes require verification.
Realtor.com’s MLS listing market has 20.56% of listings price-reduced and a pending-to-active ratio of 67.77%; these measure seller concessions and listing status, not closed prices or proof of demand. Net migration was 44 tax-return households, but inbound movers’ average income had a calculated $3,722 gap below outbound movers’, limiting the flow’s purchasing-power signal. The reported investor share was 13.98% across 379 purchase mortgages: participation evidence, not a measure of cash buyers, winning bids or tenant demand.
Inland flood is the dominant hazard; modeled annual building-value loss is 0.17%. Parcel-level flood-zone, claims and insurance evidence is not published in this record, so the ratio cannot assign a cost to any building. QCEW annual covered workplace employment rose 1.48% to 17,231, while Manufacturing, the largest disclosed private supersector, represented 28.52% of private covered jobs. This is not resident employment, unemployment or a forecast. Obtain leases, condition reports, parcel tax bills and closed-sale comps; without them, cash flow, hazard cost and acquisition basis cannot be underwritten.
