How the Mortgage Lender Performance Gap Has Widened Since 2020
The cost gap between top and bottom-performing mortgage lenders has nearly tripled since 2020, and it hasn't meaningfully closed since. From 2008 through 2019, the average difference in per-loan production expense between top-20% and bottom-20% lender cohorts was $941. From 2020 through 2025, that gap widened to an average of $2,626 per loan, peaking near $5,000 per loan in 2023 (MBA Newslink, "Chart of the Week: IMB Total Production Expense"). This is what happened during that stretch, and why the gap has stayed wide even as the market has settled.
What Do the Numbers Actually Show?
The trend line is stark. A gap that averaged under $1,000 per loan for over a decade nearly tripled starting in 2020, and even in 2025, well past the initial disruption, the top 20% of lenders averaged $10,074 in per-loan production expense while the bottom 20% averaged $12,603, a $2,529 gap that remains more than double the pre-2020 norm (MBA Newslink, "Chart of the Week").

What Happened Between 2020 and 2023 That Widened the Gap?
The timeline lines up with one of the most volatile stretches in recent mortgage history. The 2020–2021 refinance boom drove origination volume to a peak above $4 trillion, and lenders staffed aggressively to keep up. When rates spiked in 2022 and volume collapsed, industry headcount didn't shrink in proportion. The Bureau of Labor Statistics estimates roughly 295,000 people currently work in core mortgage lending and brokerage roles, down from the 2020–2021 peak but nowhere near halved, even as volume fell close to half from its 2021 high (HousingWire, "The 200-Basis-Point Gap"). Lenders carrying fixed staffing costs built for boom-era volume absorbed that mismatch directly as rising cost per loan, and the lenders least able to flex their staffing down fastest are exactly the ones that show up in the bottom-quintile cohort.
Why Didn't the Gap Close as the Market Stabilized?
This is the part worth sitting with. The volume shock that started the widening happened years ago, but the gap in 2025 remains more than double its pre-2020 average. That persistence suggests the widening wasn't purely a temporary shock effect that would naturally correct itself once volume stabilized. It points to a structural divide: lenders who built flexible cost structures during or after the disruption have maintained a real advantage, while lenders still carrying costs sized for a different volume environment haven't closed the gap on their own.
What Does This Trend Tell Us About Staffing Models Specifically?
The timing is difficult to read any other way. A widening driven substantially by a headcount-to-volume mismatch during a period of extreme volume swings points directly at staffing rigidity as a central factor. A fixed, in-house staffing model sized for one volume environment gets punished hardest exactly when volume swings sharply in either direction, up or down. A more flexible staffing model, one that can expand or contract with actual pipeline volume rather than requiring a multi-month hiring or layoff cycle, is structurally better positioned to avoid this kind of cost exposure the next time volume moves sharply.

What This Means Going Forward
MBA is forecasting continued origination growth into 2026, but rates have remained elevated and volatile, and another meaningful volume swing in either direction is a realistic possibility, not a remote one. The lenders building flexible cost structures now are the ones positioning themselves to avoid repeating the widening this data has already shown once. Waiting until the next volume shock to address staffing rigidity means absorbing the same kind of cost exposure that's kept this gap wide for five years running.
Frequently Asked Questions
How much has the lender performance gap grown since 2020? The average difference in per-loan production expense between top and bottom-quintile lenders grew from $941 (2008–2019) to $2,626 (2020–2025), peaking near $5,000 per loan in 2023.
What caused the gap to widen during this period? A significant mismatch between origination volume and industry headcount. Volume surged during the 2020–2021 refinance boom, then fell close to half from its peak after 2022, while headcount didn't contract proportionally, leaving many lenders with fixed staffing costs spread across far fewer loans.
Has the gap started shrinking as the market has stabilized? Not meaningfully. As of 2025, the gap between top and bottom-quintile lenders remained more than double its pre-2020 average, suggesting the widening reflects a structural divide in cost discipline rather than a temporary shock that would correct on its own.
