Montgomery County presents a split screen: cash-flow investigators can test measured rent, but buyers relying on near-term appreciation should be cautious. Zillow’s 2026-06 county median home value was $346,893, alongside $1,733 monthly median asking rent and a published 5.99% gross yield before costs. That value fell 1.35% year over year, while FHFA’s repeat-transaction HPI rose 2.22% in 2025. These are different vintages and methods, not a combined growth rate; FHFA is an appreciation index, not a home value.
Market rent—not HUD’s $1,573 two-bedroom Fair Market Rent—supports the gross-yield measure. FMR is a payment standard, not an asking-rent estimate, and it must not be substituted into yield. The 1.52% effective property-tax rate raises carrying-cost scrutiny against the rent/price relationship. Insurance, maintenance, financing terms, and property-specific assessments are not published, preventing a net-yield or cash-flow conclusion.
Demand and competition warrant a mixed reading. Tax-return migration shows 8,404 more households moved in than out, and average income was higher for inbound movers; this is household-movement evidence rather than a tenant-demand measure. QCEW reports annual covered jobs at county workplaces, not resident employment, unemployment, or a forecast. The published investor measure puts nonoccupant mortgage purchases at 7.84% of 14,930 purchases, making that activity a minority of recorded purchases. Realtor.com’s MLS evidence shows 4,988 active listings, up 2.33%, and 21.42% with price reductions. Active supply and listed seller concessions require property-level competition checks; neither proves closed-sale pricing or buyer demand.
Risk remains location-specific. Inland flood is the named dominant hazard, and modeled climate loss equals 0.13% of building value per year; it is a ratio, not a dollar loss estimate. Missing flood-zone status, prior claims, insurance quotes, building condition, lease performance, and submarket closed-sale comparables prevents a defensible property underwriting conclusion. Next checks are those items alongside tax assessment and listing-specific concessions.
