Built for UAD 3.6 and the redesigned URAR

Market-time adjustments you can defend.

UAD 3.6 moves adjustment support out of the addendum and into the report itself. AppraTrace turns your local sales into clear, reproducible support for the market-conditions (time) adjustment, and every professional decision stays yours. We're inviting residential appraisers to help shape it before public release.

UAD 3.6 · Mandatory since November 2, 2026

The report changed. The need to support your adjustments didn't.

The redesigned URAR replaces the familiar forms with one structured, data-driven report. Commentary that used to live in the addendum now goes into dedicated fields in each section.

What changed

  • Adjustment support and market analysis move into the report's own sections
  • More structured, machine-readable data for reviewers
  • Less room to hide thin support in a long addendum

Where AppraTrace fits

  • Evidence for the market-conditions (time) adjustment from your local sales
  • A clear written record of your time-adjustment support that you can adapt for the report
  • A reproducible workfile behind every number, ready for review

AppraTrace is an independent tool. It is not affiliated with or endorsed by Fannie Mae or Freddie Mac, and it does not certify UAD compliance; you remain responsible for your report.

How it works

From local sales to adjustment support you can defend.

01 · Evidence

Start from market data

Work from local sales. AppraTrace checks the data, flags what needs attention and fits the time trend while holding living area constant.

02 · Judgment

You make the call

Review the estimate, its uncertainty and its limitations. Choose your adjustment and record your reasoning. Nothing is applied automatically.

03 · Workfile

Export a reproducible record

Export your documented support and a workfile with a complete audit trail and a checksum, so a reviewer can verify exactly what you relied on.

Your judgment

Built to support appraisers, not replace them.

We say plainly what AppraTrace does, and what it never does.

It does

  • Fit and show the market trend in your data
  • Show uncertainty and limitations honestly
  • Record every decision with your reasoning
  • Support supervisor review of trainee work

It never

  • Selects an adjustment for you
  • Concludes a value
  • Hides the data behind a score
  • Claims compliance on your behalf
Your data

Private by design.

Firm isolation

Each firm's work is kept separate and checked on every request.

Demo data provided

Council members work with realistic demo datasets. Nothing of yours is required, and uploads stay off during the closed beta.

Full audit trail

Every step is recorded and verifiable. Testing activity is recorded only to improve the product.
