finally done right.

Stop re-typing the same data across forms. AppraisalOS reads your contracts, pulls public records, and auto-fills your UAD 3.6 report — so you focus on the appraisal, not the paperwork.

Real comps. Real adjustments.

Map, grid, and AI-suggested adjustments with reasoning you can defend.

MISMO 3.6 native.

Sketch

The only sketch tool that lives where your report lives.

Aivre and the rest send you to a different app. We don't. Draw it, label it, calculate it, and watch the GLA land in the form before you finish the wall.

  • Multi-level support with auto GLA roll-up
  • ANSI Z765 area calculations enforced
  • One-tap MISMO exhibit attachment
  • No subscription to a second sketch app

Aria · your review partner

She reads the whole file
before you click export.

Aria runs every gate — XSD, UAD 3.6 compliance, package completeness, conditional-required rules — and explains exactly what's missing, in plain English. No AI slop. No nagging you while exporting anyway.

Mentorship

Bring a trainee along
without the paperwork tax.

The real bottleneck for new residential appraisers is not demand — it's the number of supervisors willing to take one on. We built a workflow for the supervisor first: per-section signoff with coaching notes, an hours log you approve once, and a clean experience-log export the trainee carries to their state board.

Durable supervisor link

Add a trainee once. Supervised files inherit the relationship.

Per-section signoff

Approve or send back each URAR section with a coaching note.

Hours the supervisor approves

Inspection, report, research, review, training — per file, one click.

Experience-log export

ZIP with manifest + CSV + JSON of approved hours. A transcript, not a certificate.

Trust

The export button
has a conscience.

Every other tool nags you in the UI then exports anyway. AppraisalOS enforces blockers in the server route. If the readiness engine, the lock, or the supervisor signature isn't there, the deliverable doesn't happen.
