A findingyou can defend.

Before a finding is published, a second automated review tries to rebuild it from the source documents and the guideline. If it cannot, the finding goes back and does not publish. What reaches your team is a finding that stood up to that check: what was found, and each path that would resolve it.

2026-002087FHA purchaseOpen findings
FindingEvidence conflictsA $12,400 deposit lands two days after a new personal-loan tradeline that the application does not list

What the file shows

The tri-merge credit report (page 3) shows a personal-loan tradeline opened August 12, 2026, with an original amount of $12,500 and a monthly payment of $384.

The August bank statement (page 2) shows a deposit of $12,400 posted on August 14, 2026, two days after the tradeline opened per the credit report.

The Uniform Residential Loan Application's liabilities section (page 3) does not list a personal loan anywhere among the borrower's disclosed monthly obligations and payments.

How Flightline reached this conclusion

Governing requirements

Requirement

Borrowed funds as a liability

FHA Single Family Housing Policy Handbook 4000.1II.A.4.deffective Jan 1, 2026

Borrowed funds secured or unsecured must be documented as a liability of the borrower and are not an acceptable source of funds to close without that documentation.

Why it applies

This is an FHA-insured purchase where borrowed funds must be documented as a liability rather than treated as cash to close, so a personal-loan tradeline opened days before a matching deposit reaches directly into both the liabilities section and the funds-to-close calculation.

Why this matters

If the deposit is loan proceeds, both cash to close and the qualifying debt-to-income ratio must be recomputed with the $384 payment included, moving the ratio to 47.1% and threatening eligibility, insurability, and salability of the loan as structured.

Explanations

Explanation and basisAssessment

A personal-loan tradeline for $12,500 opened August 12, 2026, and a $12,400 deposit posted two days later, funding 74.9% of the $16,566 cash to close; the liabilities section does not list the loan, and the file does not establish whether the deposit is loan proceeds.

Best-supported explanation

The deposit is unrelated to the tradeline and reflects a coincidental transfer from another source

Evidence considered

No transfer confirmation or source statement identifying the deposit's origin was located in the file.

Plausible · unverified

The personal loan belongs to a co-borrower or another party, not to this borrower

Evidence considered

The credit report used to identify the tradeline is pulled under this borrower's own name and file.

Not ruled out

The tradeline was opened for an unrelated purpose and the proceeds were not deposited into this account

Evidence considered

The two-day gap between the tradeline opening and the deposit was weighed against typical loan-disbursement timing.

Your standards,cited to the section.

Each finding is measured against the agency and investor requirements that apply to the loan, then your overlays, then your QC plan. It cites the requirement it applied, to the section, as it stood on the review date. Guides change; a citation to the wrong edition does not survive a rebuttal.

When your QC plan says the question is what applied at application or closing instead, the review follows it.
