Total Expert Founder & CEO Joe Welu recently joined the HousingWire Daily podcast to break down how AI is helping lenders have smarter, more personal conversations with borrowers—at a scale that simply wasn't possible before.
In early 2025, Total Expert launched our AI Sales Assistant. Since then, the mortgage industry's relationship with AI has fundamentally changed—and Total Expert Founder and CEO Joe Welu says the results have been unlike anything the company has seen in over a decade of building lending technology.
"The innovation this past 6 to 12 months has been nothing short of extraordinary," Welu told HousingWire's Sarah Wheeler. "The results that we've been able to get with our customers have been really like nothing we've ever seen."
The lending challenge AI is built to solve
At its core, AI Sales Assistant addresses one of lending's most persistent challenges: the gap between an originator’s intentions and their bandwidth. Even the best originators can only connect with so many contacts in a given day, week, or month. And if they want those connections to feel personalized from the borrower or homeowner’s perspective, cookie-cutter emails and phone calls won’t cut it. It takes time. And that’s a very finite resource.
So, originators have a choice: spend time making each interaction more impactful but reduce the number of contacts they can engage or choose quantity over quality and risk eroding your relationships by failing to personalize your communications.
AI Sales Assistant was designed to close that gap not by replacing originators but by giving them something they've never had: perfect memory and infinite reach. Nobody can remember every detail from a conversation they had six months ago, and they can't personally reach out to every past customer when rates drop or when they reach an equity threshold.
"If you think about a top producing originator who wants to stay really deeply connected to their customers," Welu explained, "the dependencies are often just the time and human horsepower required to reach out and engage with every one of those consumers."
AI Sales Assistant is on pace to 130 million calls this year; each one personalized to the borrower or homeowner’s specific financial situation, tailored to meet the lender’s unique brand, and trained to comply with industry regulations.
Context is everything: Introducing Customer IQ
What makes Total Expert's approach different isn't just the volume of conversations; it's the depth of context behind each one thanks to Customer IQ.
Customer IQ aggregates and analyzes the data that matters most for homeownership and lending: servicing data, real-time product and pricing information, conversation history, consent records, and more. It creates a continuously enriched contact record of every customer and lead, so that every human and AI-powered engagement is grounded in what actually matters to that borrower right now—even as short-term priorities shift and long-term goals evolve.
"Context is really about helping our customers understand what matters most to that consumer at any given time," Welu said.
When a borrower mentions during a call that they're helping their child buy a house, or that they're thinking about downsizing for retirement, that context gets captured, fed back into Customer IQ, and made available to the originator so their next conversation will be more personalized and more meaningful.
The human–AI handoff
A key design principle for Total Expert is knowing that there will always be a time when AI needs to step aside and let a human take over. If a borrower hesitates or the conversation isn't flowing, our AI Sales Assistant detects it and seamlessly offers to connect the consumer with an originator in real time or schedule a meeting for a later date.
"Because our AI is trained specifically on mortgage use cases and the types of conversations originators are having every day,” Welu continues. “The AI can sense when conversation isn't going in the direction we want it to," Welu explained. "At that moment, if the originator is available, we can live transfer that customer and just get two humans on the phone."
Lenders have significant control over how and when that handoff happens. Total Expert works closely with each customer to craft conversation flows that match their brand, their compliance requirements, and their vision for the borrower experience.
Unlocking products lenders have left on the table
One of the most compelling use cases for AI in lending is to surface home equity opportunities that originators have historically had little time or interest to pursue. That’s because equity discussions often require educating homeowners on their options for leveraging that equity. If a homeowner doesn’t have an immediate need to pay down debt or fund a large expense, for example, those conversations can quickly become dead ends.
But if Customer IQ identifies a homeowner with significant high-interest revolving debt and available home equity, AI Sales Assistant can leverage that insight to proactively reach out, explain the consolidation opportunity, and send the homeowner a link to start the application—all while keeping the originator informed as the opportunity moves forward.
"The originator retains a customer, their brand stays at the forefront, and the homeowner gets an incredible financial outcome," Welu said. "And now the relationship becomes deeper and more connected because you've been able to deliver something they didn’t expect but definitely needed."
Democratizing what only the biggest lenders could do
Historically, maintaining consistent post-close outreach required massive call center operations that only the largest organizations could sustain. Voice-first AI agents combined with Customer IQ level the playing field for lenders, banks, and credit unions of all sizes.
"What voice AI has done is democratize it," Welu said. "Customer IQ with voice AI gives every lender the ability to say, why can't we have 100% retention of our customers? What's stopping us now?”
Lenders using Customer IQ + AI Sales Assistant have already doubled their recapture rates. And as rate windows open and close with increasing speed, the ability to reach the right borrower at exactly the right moment has never been more valuable.
What's next?
Looking ahead to the rest of 2026, Welu is energized by what he sees as a fundamental reimagining of the lending industry, one where AI elevates people to the highest levels of both creativity and productivity, and where consumers consistently receive the kind of personalized, contextually aware experience that was previously impossible to deliver at scale in this industry.
"I'm excited and energized every day by this reimagining of what’s possible in our industry," he said. "We can elevate people to a place that makes their jobs more meaningful and fulfilling. Ultimately, that will lead to better, more consistent outcomes for consumers. It's win-win across the board."
