Loan and MBS Data and Analytics

Berkshire uses assumptions derived from its collateral database for internal modeling purposes and for completing predictive modeling assignments. Some clients, however, want to search the data for their own terms, on their own terms. We offer that flexibility, and we offer data hosting and analysis as a subscription service to those clients. If however, you desire expert analysis, a fresh perspective, and unique solutions, Berkshire offers those services through our Predictive Modeling service. 

Data Platform Overview

Berkshire tracks monthly performance on more than 20 million privately securitized loans (2.5 million active) and over 239 million agency mortgages (41.5 million active.) Some of the highlights of our data platform are:

  • Massive, up-to-date MBS and ABS databases (Agency data going back 30+ years, non-agency going back 15+ years)

  • Loans mapped to pools, groups and CUSIPs (except for CAS and STACR loans originated before agencies started provided loan level detail by security)

  • Secure web hosting on our public cloud platform (powerful, easy-to-use tools for defining queries, slicing and dicing)
  • Rich data field content, continuously gathered, updated, normalized, verified, and validated (agency data updated monthly upon release, non-agency data within hours or days after release, depending on shelf)
  • Pre-defined and custom reporting and exports to Excel
  • Custom model building
