Real estate buyer enquiries coming in over WhatsApp needed constant back-and-forth — answering config and budget questions, sharing brochures, tracking document status and booking site visits — which ate up a relationship manager's day on repetitive conversations.
We built a stateful AI agent on n8n that tracks each buyer's stage (enquiry, docs, visit booking) across the whole conversation, pulls live inventory to answer config and floor questions, auto-sends brochures, flags hot leads and completed paperwork to the RM, and books site visits directly onto the calendar with a WhatsApp confirmation.
