Mortgage Production Ranking Methodology
How TopMortgageOriginators.com rankings are produced from MMI’s nationwide residential mortgage public record dataset.
~95% county coverage
MMI collects mortgage transaction data from recording jurisdictions covering approximately 95% of U.S. counties — sourced from official county and parish recording offices, not surveys or voluntary submissions.
Daily ingestion, ~22 day latency
MMI ingests new public-record filings on a daily cadence; individual transactions typically appear in the dataset about 22 days after the recording date. Latency varies by jurisdiction because recording cadences differ by county.
NMLS-matched, deduped, validated
Transactions are matched to NMLS identifiers for loan officers, lenders, and brokers where applicable, then deduplicated, normalized, and quality validated to produce an authoritative production view.

Frequently asked questions
Where does this data come from?
MMI collects residential mortgage transaction data from public recording jurisdictions across the United States. The dataset is sourced from official county and parish recording offices — not from voluntary lender submissions or surveys.
How much of the country does the dataset cover?
MMI ingests mortgage recording data from jurisdictions covering approximately 95% of U.S. counties, which together account for the overwhelming majority of residential mortgage origination volume nationwide. The remaining ~5% are smaller jurisdictions where electronic recording feeds are unavailable or impractical to aggregate; their absence has a minor effect on national rankings and varies by state.
How current is the data?
Recorded mortgage transactions typically appear in the MMI dataset approximately 22 days after the recording date. Latency varies by jurisdiction because recording cadences differ by county.
How often is the dataset updated?
MMI ingests new public-record filings from recording jurisdictions on a daily cadence. That means newly arriving transactions reach the dataset every day, but each individual transaction still carries the ~22 day average latency between when it was recorded with the jurisdiction and when it appears in MMI — the time it takes for the recording office to publish the filing electronically and for MMI's pipeline to ingest, deduplicate, normalize, and validate it.
How are loan officers, lenders, and brokers identified?
Transactions are matched to NMLS identifiers for loan officers, lenders, and brokers where applicable. NMLS is the Nationwide Multistate Licensing System, the industry-standard registry for residential mortgage licensing in the United States.
How are duplicates handled?
MMI deduplicates, normalizes, and validates the underlying transactions to produce a canonical view of mortgage production. Records are matched across recording jurisdictions and identity-resolved to a single transaction even when the same loan appears in multiple filings.
Why might these rankings differ from lender-reported figures?
Rankings on TopMortgageOriginators.com use recorded public-record mortgage transactions available to MMI at the time of publication. They may differ from self-reported rankings, survey-based lists, or lender-reported production figures because they reflect what was actually recorded with the relevant jurisdiction.
