PLUMB BOB IS A CHAT — YOU TYPE OR TALK, IT FILLS THE REPORT.
Plumb Bob is a conversational co-pilot for residential appraisers preparing for the November 2, 2026 UAD 3.6 mandate. Inspection notes to compliant XML, without the form-filling — plus a compliance check that flags what would bounce, before you submit. Keep the forms software you already use — Plumb rides along.
PRIVATE TO YOUR ACCOUNT · NOT A GSE-VERIFIED DELIVERY PLATFORM — RIDES ALONGSIDE THE VERIFIED SOFTWARE YOU ALREADY USE
Describe the property the way you'd tell a colleague — or dictate it, or upload your field notes as a PDF. No fields to find.
Plumb Bob drafts each section; you confirm or correct it. It refuses to finish a report that contradicts itself.
Compliant UAD 3.6 XML, a URAR PDF, and a submission ZIP — you still deliver through your own forms software.
Describe the subject in plain language. No tabs, no forms, no field-by-field navigation.
Drop in field photos. Plumb Bob identifies rooms, fixtures, and surfaces — and flags condition evidence for your rating. It never assigns a C1–C6 you didn't state.
Every line traceable back to the documented market rule it came from. Defensible by design.
Generated against the published UAD 3.6 schema and checked against the Appendix H-1 rules before you submit through your own verified software.
Reviewable draft in the standard URAR layout. XML and PDF stay in lockstep.
Validated before delivery — full XSD plus roughly 400 of the 508 Fatal Appendix H-1 rules (~78%), with the exact count printed on every report. Errors surfaced in plain English, not stack traces.
You don't have to take our word for it.
Fannie Mae and Freddie Mac publish five complete sample scenarios with the official UAD 3.6 file each should produce. We run every scenario's narrative through Plumb Bob and compare our output to theirs, field by field — ground truth by construction.
What Plumb captures, it gets right — and what it doesn't check, it says plainly. A PASS here never claims more than it measured. That's the whole product.
