MISMO 3.4

Mortgage Industry Standards Maintenance Organization version 3.4 — the canonical XML schema for loan applications, used widely by LOS systems.

RateStack accepts MISMO 3.4 XML at the loan-import endpoint and maps it to the canonical RateStack loan shape. ULAD (Uniform Loan Application Dataset) follows MISMO 3.4 conventions and is also supported.
