Montgomery County presents a valuation-versus-underwriting tension: the Zillow county observation labeled 2026-06 puts the median home value at $200,474, up 6.9% year over year, while FHFA’s 2025 repeat-transaction index fell 8.27% over its annual measure. Investors able to verify unit rent, flood exposure and insurance should investigate the discrepancy; purchasers relying on a headline value trend or a modeled yield should be cautious. These are differently dated, differently constructed measures, not a single price trend.
FHFA’s 2025 index also shows a 49.53% cumulative five-year gain, but it is an appreciation index rather than a dollar home value and should not be averaged with Zillow’s observation. A $925 two-bedroom HUD FMR is a payment standard, not asking rent. No county market rent is published, so gross yield cannot be computed. Carrying-cost review starts with a 0.64% effective property-tax rate and $1,037 median annual tax; neither establishes taxes for a particular property.
Household movement is modestly positive: 616 tax-return households moved in and 548 moved out, a calculated net gain of 68; incoming movers’ average income exceeded outgoing movers’ by $6,490. That supports a demand lead worth testing, not proof of tenant demand. Investor mortgages were 3.58% of purchases, suggesting limited measured non-owner competition but not a count of cash buyers. QCEW’s 2025 annual average recorded 8,764 covered jobs, down 1.89%; the $966 average weekly wage applies to covered workers. Manufacturing is the largest disclosed private supersector, not the whole county economy.
The central risk is inland flood: modeled annual climate loss equals 0.14% of building value, a county-level estimate that requires parcel-level flood, elevation, insurance and deductible review. No Realtor.com figures are published, so visible MLS supply, marketing time and seller price reductions cannot establish buyer competition or exit liquidity. Also absent are market rent, operating expenses and property-specific condition; without them, an underwriter cannot determine gross yield, net operating economics or whether the value-signal conflict is investable.
