Montgomery County presents an underwriting tension: a published market-rent yield and rising covered-worker wages sit beside softer price and MLS listing signals, net out-migration, and inland-flood exposure. Buyers who can verify a property-level lease and flood cost should investigate acquisition basis; those relying on near-term resale, FMR support, or broad county averages should be cautious. County-level evidence does not establish neighborhood tenant depth, insurance, or condition.
At Zillow’s county 2026-06 observation, the $627,198 median home value was down 1.43% and the $2,346 monthly median asking rent was down 0.32%. The supplied gross yield is 4.49% before costs. HUD’s two-bedroom FMR is a payment standard, not asking rent; it cannot substitute for the measured market rent. The effective property-tax rate is 0.87%, a carrying cost to test against the yield. FHFA’s 2025 annual repeat-transaction HPI, not a home value, rose 1.32%. That reading cannot be averaged with Zillow’s decline because their methods and vintages differ.
Realtor.com’s 2026-06 MLS evidence describes the visible listing market: median listing price fell 8.26%, active listings rose 14.22%, median marketing time was 37 days, and 18.29% of listings had a price reduction. These are asking prices, visible supply, marketing time, and seller concessions—not closing prices or proof of buyer demand alone. Tax-return movers show more households left than arrived and a higher average AGI among leavers, weakening the interpretation of migration as a purely volume statistic. The 5.84% investor share of 8,709 purchase mortgages identifies a buyer cohort, not all-cash activity or competitive intensity.
The modeled annual climate-loss ratio is 0.06% of building value, aligned with inland flood but not a property loss estimate; it warrants parcel flood-zone, elevation, drainage, insurance-quote, deductible, and coverage review. Supplied QCEW annual data cover jobs at county workplaces: employment fell while average weekly wage rose, and Professional and business services was the largest disclosed private supersector, not the whole economy. QCEW is neither resident employment, unemployment, a forecast, nor a metro CES/LAUS series. Missing property-level lease terms, occupancy, turnover, expenses, insurance, flood claims, financing, and closed-sale comps prevent underwriting net cash flow, buyer depth, and flood-adjusted value.
