A real estate broker, an associate real estate broker, or a real estate salesperson may not refuse to show any residential property or prospective site for a residence that is available for sale, rent, or sublease to a prospective buyer or renter because of: the race, color, religion, sex, marital status, national origin, or, as defined in § 20–701 of the State Government Article, disability of the prospective buyer or renter; or the composition or character of the neighborhood where the property is located. If the representation is made because of the race, color, religion, sex, marital status, national origin, or, as defined in § 20–701 of the State Government Article, disability of the prospective buyer or renter or because of the composition or character of the neighborhood where the property is located, a real estate broker, an associate real estate broker, or a real estate salesperson may not represent to a prospective buyer or renter that the available residential properties, prospective sites for a residence, or listings in a specified price range are limited to those already shown when, in fact, there is an additional residential property, a prospective site for a residence, or a listing in a specified price range that is available and within the price range specified by the prospective buyer or renter.
