Key Insights to Remember
- Automation has long been woven into mortgage lending since the 1990s, yet it stands apart from the fresh wave of generative AI innovations.
- Nowadays, an emerging number of lenders are harnessing generative AI to ramp up loan processing capabilities and guide borrowers through the maze of loan options.
- A broader regulatory framework remains a prerequisite for generative AI to gain widespread traction in mortgage lending.
The Idea of AI Listening In: How Comfortable Would You Be?
Imagine every exchange with your lender is quietly accompanied by an AI assistant, attentively taking notes behind the scenes.
This practice isn’t the norm yet, but it’s rapidly inching toward becoming standard operating procedure. Leading mortgage providers are increasingly championing AI as a game-changer that accelerates and simplifies the lending process, all while boosting the volume of loans they can handle.
What exactly does AI entail? How might it serve you within the mortgage labyrinth? And what safeguards are in place to shield you? To clarify these points, we reached out to specialists at forward-thinking mortgage tech firms.
Unpacking the Distinction: Generative AI vs. Classic Automation
Mortgage lending today predominantly leans on automation tools like Fannie Mae’s Desktop Underwriter to handle much of the workload. However, when discussing AI, it’s crucial to separate the well-established automation solutions from the buzz surrounding generative AI, fueled by breakthroughs such as ChatGPT and DALL-E.
“Many throw around the term AI, yet few actually deploy true generative AI,” remarks Brad Seibel, president of Sage Home Loans. According to him, technologies supporting online lending and rapid preapprovals have been in play for quite some time. (Notably, Sage is part of Red Ventures, Bankrate’s parent company.)
A prime example in underwriting is OCR—Optical Character Recognition—which enables loan officers to digitize text from scanned or photographed documents, whether typed or handwritten.
Christopher Jaynes, VP of Product Forward Home Loans at Sage, positions OCR squarely within traditional machine learning paradigms. While machine learning is a subset of AI, it’s distinct from generative AI. In mortgages, OCR assists in digesting uploaded paperwork to assess your eligibility and tailor loan offerings.
Generative AI, on the other hand, is a newer breed of technology that synthesizes existing data to craft fresh content. Jaynes notes that generative AI complements OCR by refining the gleaned information.
Josh Zook, CTO of Rocket Mortgage, adds, “Though AI has been part of the game for years, it’s the surge around generative AI that’s unlocking new potential across the mortgage cycle.”
Let’s explore how lenders are weaving generative AI into their workflows.
Generative AI As Your Virtual Mortgage Guide
Chat functionalities on lender websites aren’t a novelty, but today’s tech enhancements empower them to offer richer, more insightful interactions. Borrowers can now engage with AI chatbots to uncover various loan options, estimate eligibility, and even kick off applications.
Robert Heck, SVP of Revenue at Morty (an online mortgage platform), observes, “A growing number of companies leverage chatbots to facilitate real conversations with consumers about their mortgage needs—covering everything from product discovery to completing the 1003 loan application form via AI-driven dialogues.”
Understanding Form 1003 (URLA)
The Universal Residential Loan Application, known as Form 1003 or URLA, is the standardized document devised by Fannie Mae for mortgage applications.
Picture landing on a lender’s website, starting your loan paperwork through a chatbot, while generative AI quietly powers the backend, seamlessly moving your application toward underwriting and eventually closing.
Speed and Precision: Generative AI’s Role in Loan Processing
For loan officers juggling voluminous applications, generative AI emerges as an indispensable ally in extracting and organizing vital information.
Jaynes points out, “Anyone familiar with mortgages knows the mountain of documents involved—your closing packets alone can reach 300–400 pages of contracts, disclosures, and supporting paperwork.”
With AI’s ability to distill sprawling paperwork into digestible insights, loan officers are better equipped to guide borrowers smoothly through the process.
“These AI-powered tools function like co-pilots, accelerating comprehension of complex and lengthy guidelines, sometimes spanning over 1,400 pages,” says Heck. “They help teams zero in on concrete criteria more rapidly.”
Moreover, generative AI excels at interpreting scanned materials—pay stubs, bank statements, W-2s—enhancing the fidelity of document processing.
| Documents processed monthly | 1.5 million |
| Document type identification accuracy | 70% |
| Data extraction accuracy from documents | Over 90% |
According to Zook, Rocket Mortgage has achieved notable success, using AI to correctly identify 70% of incoming documents and extract upwards of 90% of their data. This not only trims down manual data compilation time but also reduces human errors.
Beyond paperwork, AI tools are eavesdropping on client calls, capturing crucial information during conversations.
“Our AI listens in while bankers chat with clients, pulling out critical details that typically require manual entry,” describes Zook. “This frees bankers to focus on nurturing client relationships instead of wrestling with administrative tasks.”
Such AI-driven transcription diminishes the risk of errors born from human oversight, enhancing accuracy.
Potential Pitfalls: When AI Trips Up
Generative AI may cut down on human slip-ups, but it’s not flawless. “Hallucinations”—errors emerging spontaneously—pose a risk.
Jaynes explains that language-focused generative AI models, like ChatGPT, predict text sequences from massive corpora and excel in linguistic tasks but stumble with math.
When crunching numbers crucial to mortgages, guessing isn’t an option. Although OpenAI introduced hybrid models where AI generates code to calculate figures, accuracy remains inconsistent, says Jaynes.
Another troubling issue lies in bias. For instance, analyses revealed ChatGPT-4 nudged prospective homebuyers towards racially segregated neighborhoods, matching Black buyers with majority-Black areas and white buyers with predominantly white neighborhoods. This bias was especially stark in cities like New York and Chicago.
Before being embraced wholesale, lenders and borrowers must place their faith in AI developers and the fairness of their outputs.
Regulatory Roadblocks: Why Adoption Will Be Gradual
“Given the mortgage industry’s heavy regulation, change unfolds over years, not months,” Heck observes.
Government bodies are beginning to weigh in on AI’s role in housing finance. In September 2023, the CFPB clarified that lenders must explicitly state grounds for credit denial, even when AI contributes to the decision.
CFPB Director Rohit Chopra emphasized: “Artificial intelligence expands data usage and reasons for denial, but creditors must offer clear explanations. No special exemptions exist for AI.”
Furthermore, HUD released guidelines in May 2024 detailing compliance requirements when using AI and algorithms in mortgage advertising, reinforcing the regulatory guardrails.
“We’re still in the infancy of generative AI’s potential,” concedes Jaynes.
More governance and direction from policymakers are essential before AI becomes commonplace. Since mortgages sold and securitized must align with strict criteria, AI’s role remains limited until these institutions adapt.
Seibel adds, “Even if AI suggests a paystub isn’t necessary because employment looks verified, banks demand that documentation to purchase loans. Adoption hinges on the entire loan lifecycle accepting these AI decisions.”
The Enduring Power of the Human Connection
Despite rising automation, many borrowers yearn for human interaction during the mortgage process.
“People generally seek and place trust in genuine human touchpoints,” Heck remarks, highlighting the emotional stakes involved in buying a home.
Rocket Mortgage’s Zook sees AI as a liberator of human potential rather than a replacement.
“Our approach pairs AI’s strength in data management with humans’ knack for personal coaching,” he explains.
AI handles data entry and uncovers patterns, allowing loan officers to guide borrowers empathetically through their journey.
“We maintain human oversight in all lending decisions; AI never replaces the final sign-off,” assures Zook.
Ultimately, the human stamp of approval remains the cornerstone of mortgage lending—and that’s unlikely to shift anytime soon.
