These rankings are powered by MMI's nationwide residential mortgage public record dataset. MMI collects mortgage transaction data from recording jurisdictions across the United States, with an average data latency of approximately 22 days from the recording date.
Transactions are matched to NMLS identifiers for loan officers, lenders, and brokers where applicable. MMI then deduplicates, normalizes, and validates this data to create an authoritative mortgage production dataset that powers MMI's analytics, recruiting, marketing, and intelligence products.
Rankings reflect recorded mortgage transactions available to MMI at the time of the last data refresh. Recent activity may continue to update as additional transactions are recorded and processed.
