The local Rent Act, Code 1940, Supp. VI, 45 — 1611(c) defines “rent” as “the consideration, including any bonus, benefit, or gratuity, demanded or received per day, week, month, year, or other period of time as the case may be, for the use or occupancy of housing accommodations or the transfer of a lease for such accommodations.” Discussing the question of security deposits, the United States Emergency Court of Appeals in Shaker Parkway Co. v. Porter, 157 F.2d 920, 924, said: “Making a security deposit in connection with the rental of housing accommodations constitutes both a detriment to the tenant and a benefit to the landlord within the classical definition of ‘consideration’. The tenant forgoes the use of the money and subjects himself to other burdens and risks in making the deposit; the benefits to the landlord are fairly obvious, as the complainants are well enough aware.”
