Gaithersburg rental market at a glance
Median gross rent in Gaithersburg: $2,058, about 21% above the Maryland median of $1,705. Median owner-occupied home value: $496,500, about 18% above the Maryland median of $419,900. Those are citywide medians, so an individual address can sit well on either side of them. Dividing a year of median rent by the median home value gives a gross rent-to-value ratio of 5.0%, on the low side, so the payment, not the rent, usually decides whether a file clears. It mixes apartments and houses, so treat it as a compass and not as the number for any one property.
