Closing Disclosure Variance Check Agent

Fee changes beyond tolerance are found and resolved before closing

Closing Disclosure Variance Check Agent: what goes in, what the agent does and what you get

What it does

Borrowers get a loan estimate early and a closing disclosure days before closing, and some fees change in between. Some may change by rule only within a set tolerance. Few people compare the two line by line. This agent reads both documents, matches each fee, and calculates the change. It checks each against the tolerance category: no tolerance, ten percent in total, or unlimited. It flags the changes beyond tolerance and drafts a question to the lender asking for the reason and any cure. After the lender replies, it rechecks the corrected figures. It also prepares a plain message to the client explaining the changes. The broker approves client messages. Edge case: the borrower chose a different title company, so the agent moves those fees to the tolerance group that applies.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

A fee is flagged when it rises above its tolerance group's limit. The ten percent group is checked in total, not per line.

  • Zero tolerance for lender and transfer fees that cannot rise
  • Check the ten percent group as a total
  • Move fees to the right group when the borrower changed providers
  • Reopen any issue still beyond tolerance

An example run

What happensA loan estimate shows $1,150 in recording and transfer fees. The disclosure shows $1,320. Those fees are zero tolerance, so the agent flags the $170 rise and drafts a question. The lender replies that a revised disclosure with a cure will follow. The agent checks the new disclosure, sees a $170 credit, and the broker approves a note.
