For lenders

Find the defectwhile it is still yours to fix.

Flightline reviews the file at the two points where a finding still changes the outcome: before capital is committed, and before an investor, insurer or auditor finds it.

Two control points.Where capital is at risk.

Prefunding QC reads the file while the loan can still be conditioned, cured or stopped. Post-closing QC tests it before the file leaves your hands for good. Use Flightline at either, or both.

Prefunding QC

Before capital is committed.

The file, read before the loan funds. A finding here can still condition, cure or stop the loan, which is the only point at which a defect costs nothing but time.

  • Findings in time to condition or cure
  • What resolves each one, stated plainly
  • Key figures recomputed from their source before funding

Post-closing QC

Before an investor, insurer or auditor finds it.

The file as delivered, tested against the agency, investor and program requirements that applied on the day it closed. What an investor, insurer or auditor would find, you find first, with time to respond.

  • Requirements as of the closing date
  • A sealed loan audit report for each file reviewed
  • Responses recorded against each finding

One set of findings.The oversight your program owes.

The findings your team verifies on each loan become the reporting the program owes leadership, investors and auditors, without anyone rebuilding them in a spreadsheet.

Loan audit report
Each finding on the file, sealed when it is issued, and a new edition when a finding is resolved.
Monthly QC report
Findings by program, channel, region, review area and test, trended month over month and written for leadership.
Problem spots
The same finding across many loans, located by program, channel, region, review area and test, so you know where the defect is being made.
Corrective action
A repeat finding becomes a plan: root cause, owner, deadline, and the follow-up review that shows whether it worked.

Repurchase exposurestarts as a finding no one made.

A defect that funds becomes a repurchase request, an insurance rescission or an audit finding, each more expensive than the fix would have been. The earlier it is found, the more of the outcome you still control.

What leadership and investors ask, and where the answer is

What defects are we making, and where?
Problem spots locate each repeat finding by program, channel, region, review area and test.
Is this an isolated loan or a pattern?
Each finding is counted across the loans reviewed, not left in one file.
What did we change, and did it work?
Corrective action carries an owner, a deadline and a follow-up review.
Can you show us the evidence?
Each finding cites the page it came from and the section it rests on, in a report sealed at issuance.
