Moderno, a 19-unit condo development in the U Street Corridor, did not have a grand opening party and does not hold open houses. The only marketing seems to be a lone sign on the side of the building. Surprisingly, this approach seems to be the key to selling new condos in DC. Housing Complex had a post earlier today about how successful Moderno on the corner of 12th Street and U Street has been in selling units as other developments struggle to get rid of their existing inventory.
