  • HOW IS OBMMI DIFFERENT?

  • HOW IS OBMMI DIFFERENT?

    The Optimal Blue Mortgage Market Indices™ or OBMMI™ are uniquely positioned to provide unparalleled transparency into mortgage rates by utilizing observed, real-time lock data from approximately 30% of the market. This data is aggregated daily and split in informative and novel ways, covering not only conventional 30- and 15-year fixed rate indices, but also FHA, USDA, VA, and Jumbo, as well as many Detailed Mortgage Indices of the Conventional 30 group based on Loan-to-Value (LTV) and FICO credit score. The OBMMI deliver the most complete, frequent, and informative view of the mortgage rate environment based solely on observed, real-time transactions.

  • METHODOLOGY & DEFINITIONS

  • METHODOLOGY & DEFINITIONS

    The OBMMI™ methodology is straightforward, simply taking the average rate of all appropriate locks locked through the Optimal Blue product eligibility and pricing engine on a given day. No adjustments to the rates that account for buy-up or buy-down decisions made by individuals are performed.

    These indices leverage data from Optimal Blue PPE lock requests (approximately 30% of all locks nationwide) aggregated on a daily basis and updated nightly with the previous day’s locks. Weekends and holidays are excluded due to lack of data. All applicable product types are included unless otherwise specified, and the breakdown of customer types is by mortgage company (82.49%), bank (15.30%), credit union (1.92%), and service provider (0.30%).

  • RATE INDEX RESEARCH PAPER

    The Optimal Blue Mortgage Market Indices™ (OBMMI™) are a new, rich source of data aggregated from the observed locks of approximately 30% of the mortgage market daily. As the provider of the industry-leading product and pricing engine (PPE) with over 800 customers and supporting over $600 billion in locks annually, Optimal Blue is uniquely positioned to provide the market’s most extensive and accurate view of the mortgage rates consumers are paying. There are other indices that exist, however, they are typically less frequent (updated weekly versus daily), less accurate (use survey or rate sheet data rather than actual borrower locked rate), and less timely (published on a week delay rather than a day). The purpose of this piece is to highlight some of the features of the OBMMI, examine some potential use-cases, and highlight some of the features of the series.
