Real estate data firm UrbanDigs is getting into the lead-generation game. A new service, dubbed “Sell My Apartment,” connects sellers with three potential sales agents within a matter of hours, said founder Noah Rosenblatt. “Kind of like eharmony for real estate is where we’re heading.” He said the service is a way to help sellers connect with a qualified agent, and for agents it’s a way to get a foot in the door.
