FICO Models and Credit Scoring

There are many different types of credit risk models. Some models are built for specific segments of the finance industry, including credit card, automobile, and mortgage industries, to name a few examples.  In the mortgage industry, there are numerous proprietary risk models developed by the credit repositories and mortgage insurance companies.  The universally accepted mortgage models are those developed by Fair Isaacs, called FICO models.  

Each of the three credit repositories supports several FICO mortgage models.  This happens because Fair Isaacs refines its FICO models with each repository every four to five years, and the repositories continue to support previous versions.  At the same time, the credit repositories officially advise their customers (credit agencies) to migrate to the new models, but older versions are often supported for years before they are retired.  The main reasons that mortgage lenders fail to migrate to the newest FICO model are due to internal programming limitations, especially those related to underwriting systems.  New models are also regulated by Fannie Mae and Freddie Mac.  

LandSafe uses the latest FICO scoring models approved by Fannie Mae and Freddie Mac:
