The Challenge

Client Problem

Real estate agencies lose high-intent leads during non-business hours. Human sales agents spend excessive time asking repetitive intake questions regarding budget, location preferences, and timelines instead of focusing on closing deals.

Prompt Engineering

Controlling the LLM

Engineered a multi-stage prompt state machine with explicit system instructions, role guardrails, and structured turn-taking logic. The LLM extracts buyer metadata while maintaining a natural, empathetic tone.

Workflow

Conversation Flow

  • Greeting & Intent Detection — Warmly greet caller and classify inquiry context.
  • Structured Lead Qualification — Collect budget range, preferred locations, property type, and target timeline.
  • Knowledge Grounding — Match buyer parameters against available property listings in real time.
  • Appointment Scheduling — Confirm callback preferences and write lead data via webhook.
Business Value

Measurable Outcomes & Cost Savings

Provides 24/7 coverage with immediate responses. Eliminates missed after-hours leads, boosting qualified sales pipeline volume while reducing manual support overhead by an estimated 35%.
