Facebook groups build trust for real estate agents by creating a dedicated local community space where agents provide valuable, non-sales content consistently. By sharing neighborhood news, answering questions, and spotlighting community members, agents foster genuine relationships. This ongoing engagement shows care and expertise, encouraging members to view agents as trusted resources rather than just salespeople. As trust grows, referrals and closed deals increase. Agents must prioritize serving the group with at least ninety percent helpful content to maintain credibility and reinforcement.
