The U.S. mortgage ecosystem is entering a period of elevated fraud risk, driven by shifting borrower behavior, volatile market dynamics and an evolving regulatory landscape. New analysis from Cotality’s National Mortgage Application Fraud Risk Index indicates that third-quarter mortgage fraud exposure is rising in key segments—and the macro environment surrounding oversight agencies adds another layer of uncertainty.
For lenders, compliance leaders and QC executives, the latest data signals a need for heightened vigilance and operational recalibration.
Fraud Risk Climbs, Especially in Investor Applications
According to Cotality, approximately 1 in every 118 mortgage applications in Q3 showed signs of potential fraud. While this reflects an 8% increase year over year, the report also noted a modest quarter-over-quarter improvement. Still, the broader trendline points to sustained pressure.
Cotality highlighted a particularly sharp rise in risk alerts related to declining home prices, which grew by 400% year over year—an indication that falling valuations are incentivizing misrepresentation.
The most consequential insight may be the surge in undisclosed real estate debt, a trend fueled largely by the growth in investor activity. With nearly a third of home sales in the first half of the year involving investor-buyers, Cotality observed that many investors are juggling multiple mortgages across multiple lenders, in some cases refinancing them simultaneously.
This dynamic creates opportunity for undisclosed liabilities and layered risk—especially when lenders do not have visibility into parallel applications.
Loan-Level Fraud Patterns Signal Expanding Vulnerabilities
Cotality tracks six categories of mortgage fraud, and undisclosed real estate debt was the only category to rise annually. However, sub-indicators related to income, identity and occupancy fraud also trended upward.
The highest-risk application types were:
a) Investment properties: 1 in 45 applications flagged
b) Multifamily loans: 1 in 26 applications flagged
Both segments grew their share of total mortgage applications year over year, with investor-buyer share rising from 7.3% to 10%, and multifamily applications climbing from 1.1% to 1.8%.
This shift in mix—toward segments with higher baseline fraud risk—amplifies exposure for lenders who may be understaffed or under-optimized in fraud prevention infrastructure.
Unlike consumer complaint-based fraud indicators, Cotality’s methodology reviews millions of loan applications algorithmically, flagging behavioral and data-integrity anomalies at the file level. This helps surface emerging fraud patterns before they become headline losses.
Geographic Hotspots Reflect Uneven Market Stress
Certain states showed significantly higher fraud-risk acceleration:
a) Ohio: +55%
b) Delaware: +41%
c) Kansas: +35%
d) Vermont: +35%
e) Oklahoma: +33%
While not all regions experienced broad deterioration, the data suggests concentrated pockets of vulnerability where economic conditions and property-value trends are shifting more rapidly.
Oversight Disruption at the Federal Level Complicates the Landscape
Overlaying the rise in fraud risk is an unprecedented development: the active unwinding of the Consumer Financial Protection Bureau (CFPB) under Acting Director Russell Vought. In recent public statements, Vought reiterated his intent to shut down the agency, leaving only a small number of political appointees and essential personnel in place.
The CFPB, established through the Dodd-Frank Act in 2011, has historically played a critical role in standardizing mortgage-fraud enforcement across states and federal partners—including the FHA, VA, Fannie Mae and Freddie Mac. Its dissolution introduces several challenges:
a) Reduced harmonization of enforcement standards
b) Delayed rulemaking cycles
c) Greater reliance on state regulators with varied authority
d) Intensified GSE-led enforcement
Legal developments are accelerating this shift. The Department of Justice recently issued a legal opinion suggesting the Federal Reserve may not be able to lawfully fund the CFPB going forward. By early 2026, the bureau may be unable to meet its statutory funding needs.
This regulatory uncertainty is unfolding precisely as mortgage fraud complexity grows, aided by technology-enabled identity manipulation and multilayered borrower profiles.
Industry Responses Highlight Rising Operational Pressure
Industry attorneys and compliance leaders acknowledge heightened enforcement activity from GSEs in 2025, including more frequent lender approvals being revoked and additional placement of firms and individuals on exclusionary lists.
There is also a growing industry emphasis on tightening guardrails around occupancy fraud, particularly in business-purpose lending—an area experiencing strong deal flow and investor participation.
As Timothy Ofak of Weiner Brodsky Kider notes, undetected borrower fraud has downstream implications, including repurchase demands and indemnification obligations. The financial exposure can be substantial, especially for lenders without rigorous QC and data-validation systems.
State regulators, meanwhile, continue to monitor lender-side compliance, though jurisdictional limits prevent them from policing consumer-side fraud. While the loss of CFPB partnership is viewed as “unfortunate,” many state agencies report they are continuing operations without material disruption.
Strategic Takeaways for Lenders and QC Leaders
With fraud risk rising—especially in investor and multifamily segments—lenders should prioritize:
a) Strengthened income, identity and occupancy validation protocols
b) Cross-lender visibility strategies, including advanced data-matching solutions
c) Enhanced file-level audit routines across pre-funding and post-closing
d) Scenario planning for heightened repurchase and indemnification activity
e) Active monitoring of state-level enforcement shifts as federal oversight evolves
The intersection of elevated investor activity, rising undisclosed-debt patterns and regulatory transition marks a critical moment for lenders to reinforce their fraud-risk posture.
