Brown County presents a valuation-versus-income tension: investors relying on current cash flow or an easy resale case should investigate, not treat modest appreciation as sufficient. Zillow's June 2026 county median home value was $157,468, up 0.38% year over year. FHFA's 2025 repeat-transaction HPI rose 4.06% year over year. Both measures have positive direction, but FHFA is an index, not a home value; their different methods and labelled periods cannot be combined into one growth rate.
Measured market rent is not published, so gross yield cannot be computed. HUD's two-bedroom FMR of $961 per month is a payment standard, not an asking-rent estimate, and cannot replace market rent. The 1.10% effective property-tax rate is a carrying-cost input alongside acquisition price, but insurance, maintenance, vacancy and assessment evidence are not published. Realtor.com's MLS listing price, active listings, days on market and price-reduction figures are also absent, preventing a read on visible supply, concessions or marketing time.
Demand evidence is mixed and narrow. QCEW's 2025 annual workplace series—not resident employment, unemployment or a forecast—shows covered employment up 1.01%; the average covered-worker weekly wage was $916. Trade, transportation, and utilities held 262 jobs, or 26.98% of private covered employment: the largest disclosed private supersector, not the whole economy. Tax-return migration was negative by 8 households, with a $17,098 AGI gap indicating lower average income among arriving movers. Investor mortgages were 2 of 19 purchases, or 10.53%, showing participation in a small purchase count rather than proven buyer depth.
Inland flood is the dominant hazard; modeled annual building-value loss is 0.10%. That county-level ratio requires parcel flood-zone, insurance-premium and deductible review and cannot be converted here to dollars. The thesis can fail if actual rents do not cover operating costs, flood terms undermine carrying costs, or unpublished MLS conditions show illiquidity. Obtain rent rolls or contemporaneous asking rents, tax bills and assessments, insurance quotes, flood maps and recent closed-sale comparables; without them, cash-flow and exit-price underwriting remain unsupported.
