Brian Erhahon, 29, leads his 275 agents with a pay-it-forward attitude. “Anything I can do to share information, and be open and accessible so that agents get what they need, I’ll do it,” says this first-generation Nigerian-British-American. Whatever it takes to help them grow their business, he’s on it. If an agent needs an assistant, he’ll search for talent and help conduct interviews. In their high-inventory market, he’ll bring in high-volume real estate pros from around the country to talk up their systems. All agents in his area—even from competing companies—are welcome to these events, which have drawn upwards of 200 attendees. “We’re open and transparent and just like to collaborate,” Erhahon says.
