Montgomery County presents a price-versus-underwriting tension: Zillow’s supplied county observation reports a $230,218 median home value, up 5.01%. FHFA’s 2025 repeat-transaction HPI increased 1.68%, and its cumulative five-year change was 55.21%. The measures use different methods and supplied observation periods; they cannot be averaged. Appreciation-sensitive buyers should investigate transaction-level comparables and employment exposure before treating the Zillow direction as underwriting support.
Rental underwriting is constrained: market rent is not published, so gross yield cannot be computed from the supplied home value. HUD’s $905 two-bedroom FMR is a payment standard, not asking rent, and cannot substitute. The effective property-tax rate is 0.74%, with a $1,265 median annual tax. These carrying-cost figures should be modeled against actual lease quotes and assessed-value or tax-bill review; the record does not show insurance, maintenance, financing, or property-specific assessments.
Demand evidence is mixed rather than conclusive. In the supplied annual QCEW record, covered employment at county workplaces declined 3.61%, while the average weekly covered-worker wage rose 2.75%. Manufacturing, the largest disclosed private supersector, accounts for 31.32% of total private covered jobs, creating a concentration question rather than describing the whole economy. Net tax-return migration was positive, but inbound movers’ average income was $2,103 below outbound movers’—a calculation from the reported averages. Investors made 41 of 309 purchases, or 13.27%; that is buyer-competition evidence, not proof of rent demand or owner-occupant demand.
Inland flood is the named dominant hazard, and modeled annual climate loss is 0.12% of building value. This warrants parcel-level floodplain, claims, deductible, and insurance checks rather than a dollar-loss estimate. Realtor.com MLS listing price, active listings, days on market, price-reduction share, and pending ratio are not published, preventing an assessment of visible supply, marketing time, seller concessions, or current listing competition. QCEW is workplace-based covered employment, not resident employment or unemployment. Verify market rents, leases, flood insurance, tax bills, and comparable sales before testing whether price, income, and hazard costs align.
