Montgomery County presents a decision tension: Zillow’s supplied county median home value is $146,068, down 0.84% year over year, while FHFA’s separate annual repeat-transaction HPI rose 15.5%. These figures point in opposite directions but do not resolve each other: Zillow is a home-value estimate, while FHFA is an index rather than a dollar value. This is a verify-first county for buyers relying on rent coverage; those unable to validate leases, taxes, and flood costs should be cautious.
Housing economics remain unproven. HUD’s two-bedroom FMR of $919 is a payment standard, not market asking rent. Because market rent is not published, the reported home value cannot be paired with rent into gross yield, and FMR cannot fill that gap. The 1.65% effective property-tax rate provides a county-level carrying-cost screen, not a parcel tax bill, insurance quote, or operating-expense record.
Realtor.com’s MLS listing-market evidence shows more visible supply and potential seller concessions: active listings rose 57.35% year over year, median marketing time was 84 days, and 18.12% of listings had price reductions. These are asking-market measures, not proof of buyer demand or closed-sale prices. Migration was nearly balanced at net 5 tax-return households, although supplied inbound average AGI exceeded outbound average AGI by $7,358; that small flow does not establish broad housing demand. Investors accounted for 14.15% of 106 purchase mortgages, indicating participation rather than control of county purchase mortgages.
Risk limits remain material. The modeled annual climate-loss ratio is 0.18% of building value, consistent with the identified inland-flood hazard, but it is not a parcel-specific loss forecast. QCEW reports covered workplace employment down 2.06% in its annual county series; Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy or resident labor market. Next checks are closed-sale comparables, lease and vacancy evidence, parcel taxes and insurance, flood-zone and claims history, and property condition; without them, rent coverage, basis, and hazard-adjusted carrying costs remain unverified.
