Most builders overlook their most valuable lead source: realtors. While these professionals have direct access to qualified buyers and valuable land opportunities, many builders struggle to build profitable relationships with them. Here are the seven costly mistakes to avoid, and more importantly, what to do instead.   Mistake #1: Waiting for Realtors to Find You Many builders simply list their services online and hope realtors will bring them deals. This passive approach leaves money on the table.    The Smart Approach: Take an active role in building realtor relationships. Start by identifying realtors who list land in your target area. Instead of just introducing yourself, approach them with specific opportunities or solutions to their current listings.   Mistake #2: Not Understanding the Realtor’s Perspective Builders often focus solely on their own needs, forgetting that realtors need quick, reliable commissions.   The Smart Approach: Structure deals so realtors get paid faster.
