Better.com and OpenAI Revolutionize Mortgage Underwriting with AI
Online mortgage firm Better.com has partnered with OpenAI to launch a ChatGPT application designed to dramatically reduce the time it takes to underwrite a mortgage or home equity loan. The latest tool, announced on Thursday, March 5, 2026, combines Better’s mortgage engine with OpenAI’s models, potentially cutting the underwriting process from an average of 21 days to as little as 47 seconds.
AI-Powered Mortgage Processing
The application, available to loan officers at banks, mortgage brokers, and fintech firms, automates dozens of underwriting checks. This includes appraisals, title reports, income verification, credit reports, and other key metrics. According to Better CEO Vishal Garg, the system operates by simultaneously running parallel workflows, leveraging a “multiple tool call with a super long, extended logic tree and a very large context window” within OpenAI’s models CNBC.
Disrupting the Mortgage Industry
The launch expands Better’s existing collaboration with OpenAI, which already includes an enterprise-wide deployment of ChatGPT across its 1,400 employees and the use of OpenAI’s multimodal models Business Wire. Garg stated the app represents a shift for Better, evolving from a direct lender to a “mortgage-as-a-service” tech platform. The company aims to enable competitors to approve loans faster and reduce costs, directly targeting industry leaders like Rocket Mortgage and United Wholesale Mortgage (UWM).
Market Reaction and Cost Savings
News of the partnership caused a significant market reaction on Thursday. Better stock experienced a jump of as much as 5%, even as shares of Rocket Mortgage fell by as much as 6% and UWM shares dropped nearly 6% CNBC. Better claims to have already reduced the cost to originate a loan from the industry standard of $9,200 to approximately $3,000, passing the savings on to consumers New York Post. Garg estimates that the new AI-powered platform could eliminate a $20 billion “tax” currently paid by American consumers annually for mortgage underwriting.
The Tinman AI Platform
The tool is currently known as the Tinman AI Platform and is available to loan officers and financial institutions, with potential for direct consumer access in the future New York Post. Leah Price, General Manager of Tinman AI Platform, highlighted the inefficiencies within the mortgage industry and the potential for significant cost reduction.
Looking Ahead
OpenAI’s Giancarlo Lionetti expressed pride in partnering with Better to revolutionize the mortgage industry, making home financing cheaper, faster, and easier for American families CNBC. Better CEO Vishal Garg indicated that this partnership is just the beginning, suggesting further advancements and applications of AI in the mortgage sector.
