For years, private parking spaces in the District have been rising in value. Now, this small and elusive form of D.C. real estate has reached the same lofty plateau as the beachside condo. In August, Kay Parry, a management professional living in Adams Morgan, started posting e-mails on her neighborhood discussion group: “Your Adams Morgan Parking/Garage Space for My Mexico Vacation Condo!” Parry had been searching unsuccessfully for a spot for months when she decided to try some fresh bait. In exchange for a year or so of free parking, Parry and her husband are willing to trade their entire weeklong claim to a condominium time-share in Cabo San Lucas. The one-bedroom, two-bath, hacienda-style suite features a view of the Pacific, a poolside bar, and a complimentary shuttle to downtown Cabo. “So far, nobody’s contacted us with an offer,” says Parry. —Felix Gillette
