How it works

Three steps, thirty seconds.

01

Upload your XML

Paste or drag the rejected file. We validate it against MISMO 3.4 ULDD/ULAD schemas and the published Fannie Mae, Freddie Mac, and Ginnie Mae rule packs.

02

See every error explained

Field-level results with the rule citation, plain-English description, and a one-line fix. Free to view; even before you pay.

03

Download the corrected file

Pay $19 once or $199/month for unlimited fixes. Submit and verify acceptance.

Coverage

Five rejection categories MISMOFix is built to handle.

ULAD field mismatches

LoanPurposeType enum mismatch, EnergyEfficientHomeIndicator missing

Fields present in the XML but with values that don't match the ULAD enumeration or are missing required indicators.

ULDD field-level validation

NoteRatePercent precision, LoanIdentifier ↔ UniversalLoanIdentifier consistency

Numeric precision, cross-field ID consistency, and format rules that the GSE delivery engines enforce.

Borrower demographic format errors

HMDA RaceCategoryType, gender, ethnicity coding

HMDA demographic field encoding that fails delivery because the enum values don't match the spec.

Property valuation / UCDP mismatches

PropertyValuationAmount vs. delivery package value drift

Appraisal and AVM value fields that don't reconcile with the UCDP delivery package.

Appraisal report ID linkage

AppraisalIdentifier ↔ UCDP doc-file ID mismatch

The appraisal identifier in the MISMO file doesn't match what UCDP has on file for that document.

Frequently Asked Questions

When does MISMOFix launch?

Target Q3 2026. We'll email you when it's live. Joining the waitlist gets you first access at the lowest price tier.

What does the waitlist give me?

First 30 days free at the monthly tier, plus a permanent 20% discount on file pricing. You also get direct access to the product team for feedback during the beta window.

Will you train AI on my MISMO file?

No. The tool processes files in-memory, retains them for 24 hours for download access only, then deletes. Rule explanations come from a fixed knowledge base of the MISMO 3.4 spec and published GSE implementation guides; not from your data.

Why build this?

The team behind Confer is mortgage operators. We watched lenders pay $5K–$15K/mo for ACES-class enterprise QC tools while small lenders had nothing. MISMOFix is the per-file alternative for the long tail.
