Build an AI-powered real estate assistant on WhatsApp using Strands Agents SDK and AWS End User Messaging

This article demonstrates how to build an AI-powered real estate assistant on WhatsApp using Strands Agents SDK and AWS End User Messaging, enabling instant customer responses instead of delayed form submissions.

• Four specialized AI agents handle identity verification, credit scoring, fraud detection, and property valuation using Amazon Bedrock's Nova Lite model
• Strands Agents SDK orchestrates multi-agent pipelines with tool decorators for accessing external data sources like tax authorities and credit bureaus
• AWS End User Messaging Social integrates WhatsApp Business API; incoming messages route through Amazon SNS to Lambda webhook handlers
• Supervisor agent maintains conversation state in DynamoDB and sends interactive WhatsApp messages with buttons, lists, and location cards
• Demo implementation uses India-specific tools: PAN validation, CIBIL credit scores, RERA registration, and bank loan offers with EMI calculations
• Solution deploys serverlessly on Lambda with official Strands Agents Lambda Layer; full pipeline runs in under 10 seconds
• Architecture pattern applies to banking, insurance, healthcare, and ecommerce workflows beyond real estate

The multi-agent architecture enables complex business workflows to be decomposed into focused AI agents that collaborate to deliver instant results directly within WhatsApp.
