Understand Top Defects to Help Strengthen Loan Quality
Strong loan quality protects more than your bottom line; it supports sustainable homeownership and builds borrower confidence. Our latest post-purchase file review insights reveal the most common defects and emerging trends impacting lenders today, giving you actionable opportunities to strengthen your quality control (QC) program, reduce risk, and improve loan quality. Explore the key trends to see where your organization may be vulnerable — and what you can do now to stay ahead.
To maximize the benefits of this information, consider:
- Strengthen QC reviews by targeting the defects and patterns showing up most often across the industry.
- Refine discretionary sampling and QC processes to better align with industry best practices.
- Utilize tools, such as Desktop Underwriter® (DU®), DU validation service, or Income Calculator, to drive greater certainty and accuracy.
- Leverage industry defect trends to inform your training programs and improve your controls to reduce the risk of future defects.
Random Sample

Targeted and Discretionary Samples
Discretionary or targeted reviews focus on loans with a higher likelihood of having defects in manufacturing quality.
Below are the top ten initial significant defects identified in our discretionary sample of loan reviews completed last quarter of 2025 and first quarter of 2026 (October 2025 – March 2026).
Top 10 initial significant defects Q4 2025 and Q1 2026: discretionary sample
- Undisclosed liability
- Borrower not employed
- Interested party contributions exceed borrower costs
- Undisclosed mortgage(s)
- Employment validation – borrower not employed
- Misrepresentation of primary occupancy
- Monthly payments not properly calculated
- Inadequate comparable adjustment(s)
- Omission of debts documentation missing/insufficient
- Failure to adjust comparables
What is a Price-Adjusted Loan (PAL)
Many top defects lead to eligibility issues, similar data inaccuracies such as misrepresented occupancy can also result in pricing errors, categorized as price-adjusted loans (PALs).
A PAL is a loan that has one or more defects but would still be eligible for delivery if the correct data were submitted and the applicable loan-level price adjustment (LLPA) were paid.
While PALs are less common than significant defects or findings, they still signal quality issues and potential control gaps. In 2025, the leading driver of PALs across all samples was occupancy - specifically loans delivered as primary residences that were actually investment properties. Other reasons for PALs include incorrect loan to value (LTVs) based on unsupported adjustments and incorrect LTVs based on incorrectly inputs of appraised values.
Findings
Reviewing findings from a random sample can help you identify potential issues early. Although findings do not create eligibility defects, they can signal control gaps and help you reduce risk and improve loan quality. Below are the top ten findings identified in our random sample of loans acquired during the third and fourth quarters of 2025 (July 2025 to December 2025).
Top 10 findings Q3 and Q4 2025: random sample
- Inadequate comparable adjustments
- Failure to adjust comparables
- Insufficient assets to close
- Asset documentation missing/incomplete/ineligible
- Subject physical features reported inaccurately – condition/quality of construction
- Omission of debts - documentation missing/insufficient
- Income not documented - base
- Monthly payments not properly calculated
- Incorrect income calculation – rental income/loss
- Inappropriate comparable sale(s) selection - location
Key insight from the findings
The findings data points to two notable themes. Appraisal-related issues made up four of the top ten findings, highlighting an opportunity to strengthen appraisal review and feedback loops. Share appraisal findings with appraisal management companies or appraisers to help them better understand our appraisal reviews.
Several other findings involved liabilities, assets, and income documentation or calculation issues that may not create immediate eligibility defects but can still signal control gaps that warrant closer attention. For example, consider:
- Check paystubs for garnishments, including child support and alimony.
- Review bank statements for evidence of payments of obligations that do not appear on credit reports.
- Ensure real estate obligations, including tax bills, insurance payments, and HOA dues, which were often excluded or miscalculated, are correctly included.
By making the most of these insights on top defects and trends, you can strengthen your quality control, mitigate risk, and drive long-term success. Start enhancing your loan processing today and reap the rewards of improved certainty, reduced risk, and increased customer satisfaction.
