How LendingTree built a multi-agent mortgage assistant on Amazon Bedrock

Buying a home is one of the biggest financial decisions most people face, and LendingTree built a multi-agent mortgage assistant on Amazon Bedrock to make the process more straightforward.

What happened

Buying a home is one of the biggest financial decisions most people face, and LendingTree built a multi-agent mortgage assistant on Amazon Bedrock to make the process more straightforward. The assistant educates borrowers, understands their situation, and provides tailored options in a natural conversation. Borrowers must weigh purchase or refinance, conventional or government-backed, 15-year or 30-year terms, and fixed or adjustable rates. On top of that, there’s jargon like “discount points,” “origination fees,” and “debt-to-income ratio. ” It’s no wonder many people feel lost before they even start.

Practical impact for readers

LendingTree has been helping consumers sort through these choices for over 25 years, connecting millions of people with lenders to find competitive mortgage offers. The company was built on a belief that everyone deserves the tools and knowledge to make confident financial decisions. The AI-powered mortgage assistant is that next step.

Details worth verifying

The solution had to meet the same standards that have guided LendingTree from day one: accurate information, transparent guidance, and rigorous protection of user data. Operating within the regulatory requirements of the mortgage industry means content filtering, personally identifiable information (PII) protection, and compliance oversight aren’t optional features. They’re non-negotiable. That made Amazon Bedrock and its built-in guardrails the right foundation.

Who should act or wait

“Our goal was to be a trusted partner in the home-buying journey, a guide that educates consumers, understands their situation, and matches them with the right offer. The foundation models and built-in guardrails in Amazon Bedrock let us deliver that with security and compliance from the start.

What is still unclear

Many companies in the industry have added chatbots for basic questions. LendingTree wanted to go further, answering the hard questions and matching borrowers with competitive offers. That took more than one agent.
