Income misrepresentation and document risk.
Borrower-supplied documents were always the weakest evidence in a file. These are the patterns lending teams encounter, and the records that surface them.
Risk
Income misrepresentation and document risk.
Borrower-supplied documents can be among the most vulnerable evidence in a loan file because the applicant controls what is presented. Independent government-source records give the lender a source outside that document chain. AI-assisted generation and widely available editing tools have reduced the skill and time required to create convincing financial documents, making independent source verification increasingly important.
Altered wage documents
A W-2 or pay stub adjusted upward is among the most common misrepresentations, and one of the hardest to spot by eye. Wage & Income data shows W-2, 1099 and other payer-reported information available in IRS records, giving the lender an independent source to compare against borrower-provided wage documents.
Undisclosed income and employers
Payer-reported W-2, 1099 and interest information available in IRS records can identify income sources that may not have been disclosed on the application.
Identity-data mismatch
A valid SSN combined with a name or date of birth that does not correspond to SSA records can produce a No Match. Comparing all three data elements against SSA records can expose mismatched or constructed identity data — but a Match does not, by itself, prove that the applicant is the legitimate holder of that identity.
Patterns
What tends to show up.
| Pattern | How it presents | What surfaces it |
|---|---|---|
| Inflated wages | Stated income materially exceeds reported wages | Wage & Income transcript |
| Fabricated employer | Verification of employment cannot be independently confirmed | Payer named on the transcript |
| Undisclosed business | Contractor income beside a stated salaried role | 1099-NEC on the Wage & Income transcript |
| Overstated business income | Prepared statements exceed the filed entity return | 1065, 1120 or 1120-S transcript |
| Non-filing | Borrower claims a return that never posted | Account Transcript |
| Synthetic identity | Thin file, valid SSN, name and DOB do not fit | SSA verification, all three elements |
| Deceased SSN | Number belongs to a deceased individual | Death Master Index screening |
None of this makes the underwriting decision. Government-source records give you facts that do not depend on the applicant's choice of documents — what you do with a discrepancy remains yours to judge.
The core idea
A fraudulent file can agree with itself.
Every document below came through the applicant. They corroborate one another exactly as an underwriter would hope, which is precisely what makes the comparison beneath them matter.
Consistency inside the loan file is not the same as independent verification outside the loan file.
A discrepancy is a reason to investigate — not proof of fraud.
Fannie Mae’s random post-purchase sample of loans acquired in Q3–Q4 2025 ranked misrepresentation of income as the second most common initial significant defect. Misrepresentation of primary occupancy ranked first.

Two different problems, often confused.
Mortgage fraud is usually sorted by what the party was trying to achieve. The distinction matters because the two look different in a file and call for different responses.
- Income inflated
- Employment misstated
- Occupancy misstated
- Assets misrepresented
- Straw buyers
- Property schemes
- Industry participants involved
- Multiple coordinated transactions
Our records are most useful where the risk involves income, employment and payer-reported data, business tax information, or SSA identity-data discrepancies. They contribute far less to property valuation schemes, occupancy misrepresentation or title fraud — which are real risks, but not ones a transcript answers.
What to look for
Income and identity red flags.
A short list of the signals that intersect with government-source records. Industry fraud resources list many more, covering property, occupancy and transaction risk.
A red flag is a reason to investigate. Government-source verification supplies independent facts that help the lender determine whether the difference is an error, an underwriting defect, incomplete documentation or potential misrepresentation. The presence of one or more red flags does not by itself indicate fraudulent intent.

Found a discrepancy in the file?
Government-source verification does not determine fraudulent intent. It gives the lender independent facts to investigate before relying on the borrower-provided record.
