Lenders lose money on small mortgages. That single economic fact prices out the buyers who can least afford to be priced out – not through bias, but through arithmetic that treats a $100,000 loan the same as a $500,000 one in processing costs.

According to Pavan Agarwal, President & CEO of Sun West Mortgage Company, the average cost to originate a mortgage in the United States – as reported by the Mortgage Bankers Association – sits around $5,000 per transaction. That figure stays roughly the same regardless of loan size. On a half-million-dollar loan, $5,000 is negligible. On a $100,000 loan, it represents five percent of the total – a margin so thin that many lenders will not take on the work.

For a buyer looking at a starter home in a lower-cost market – parts of the Midwest, the rural South, or smaller towns across the country – this creates a frustrating situation. The buyer qualifies on paper. Income supports the payment. But the lender cannot justify the fixed costs of assembling the deal for such a small revenue opportunity.

Who Gets Left Behind

Agarwal frames this as an economic problem that produces discriminatory outcomes without discriminatory intent. “I don’t believe it’s because Americans are purposely trying to discriminate against certain class of people, but it’s just because it’s too expensive,” he says. The result: “Underserved communities get left behind. Minorities, low-income people, people with disabilities- they get left behind tremendously because it’s too expensive.”

The $5,000 is not one big expense. It is dozens of small ones: a loan officer’s time, a processor reviewing documents, an underwriter analyzing a file, compliance checks, title coordination, closing preparation. Each step involves labor. Each step costs roughly the same whether the loan is large or small.

This explains why buyers at the lower end of the market often report longer timelines, less responsive service, and more difficulty finding lenders willing to work with them.

How Automation Changes the Calculation

Agarwal’s company has built an AI-driven mortgage processing platform called Angel AI that he says has brought the per-loan origination cost below $125. At that cost, a $100,000 loan becomes as economically viable to process as a larger one.

According to Agarwal, the platform handles the full origination process – from application through underwriting to funding – with minimal human intervention. Sun West has processed over 200,000 transactions and funded over $40 billion through the system since its deployment.

Sun West is not the only company exploring automation to reduce origination expenses; several fintech lenders and large banks have invested in similar technology. But Agarwal argues the reduction is dramatic enough to change the fundamental economics of lending to lower-income borrowers. “I don’t care. I could do a thousand-dollar loan. It doesn’t matter,” he says.

He points to a mismatch between how borrowers earn money today and how lending guidelines were designed. “The guidelines in America were written back in the 60s and 70s, when everyone was expected to be working for IBM 9 to 5 and getting a steady paycheck,” Agarwal says. “And it doesn’t work that way anymore.” People with gig work, side businesses, and multiple income sources – now common – face documentation requirements built for a single-employer workforce. Lower processing costs alone do not solve that mismatch, but automated systems can analyze more complex financial profiles without the labor cost that makes such analysis prohibitive on small loans.

What This Means for Buyers Seeking Smaller Loans

When a lender seems uninterested in a $100,000 purchase, or when an application moves slowly while a larger loan flies through processing, the explanation may not be credit score or documentation quality. It may be that the borrower is not profitable enough to prioritize.

Even if origination costs drop, lenders still face regulatory requirements, servicing costs, and secondary market preferences for loan size and borrower profile. The cost barrier is one obstacle among several.

One practical step for buyers in this segment: look specifically for lenders that use technology-driven processing or that specialize in lower-balance loans. Credit unions, community development financial institutions, and fintech platforms may have cost structures that make smaller loans worth their effort. According to the Mortgage Bankers Association’s reporting cited by Agarwal, per-transaction origination costs have risen in recent years as compliance requirements have grown – meaning the gap between what small loans generate in revenue and what they cost to produce is widening, not shrinking.
