It isn’t rocket science. Be the area expert, and know the area roads. You have one chance to impress a client with your expertise, why lose it over something so simple? Get to know your market, drive your area, ask other agents to help you, and if all else fails admit if you are not familiar with a place but offer to get more information and get back to the people. Honesty will always win over false bravado and poorly deserved “expert” titles.
