Every conversation is a lead.
When a buyer is ready, she tells them exactly where their details will go and asks if they would like the listing agent to message them. Only then does she take their name and WhatsApp number, reading it back to be sure. No forms. Nothing to fill in. You receive the lead with a brief: what they want, their budget, their timeline, the questions only you can answer, and the recording of the call, so you hear how keen they are before you reply.
