Last June, I pointed you to Eric, the real estate agent in Chicago who does showings by bike. The Wall Street Journal reports on what they call a nascent development: Agents Show Houses by Bike, Pointing Out Paths, Racks, 'Tuck-Under' Garage. The article talks about how bike-friendliness is becoming an important criteria for many home buyers, and riding a bike around the neighborhood is naturally a good way to determine that.
In Boulder, Colorado, Pedal to Properties is a full service real estate company that keeps a fleet of bicycles for clients to use on showings. They go out every Wednesday night with their clients on bikes.
Update: Eric the Chicago real estate agent was interviewed for a similar story.
