How Does Loan Prospector Work?

Using statistical models, credit data from the national credit repositories and the loan application data details a mortgage originator supplies, Loan Prospector assesses the "Three C's – Credit Reputation, Capacity and Collateral" and the layers of risk to assist the originator in the originator's determination of a borrower's creditworthiness and the acceptability of the loan application.

For conventional/conforming mortgages, Loan Prospector: For each loan assessed, Loan Prospector provides the following results
  • Determines eligibility for assessment
  • Assesses borrower's credit reputation and ratios
  • Determines a risk profile by measuring the layers of risk present in the mortgage application
  • Determines the minimal appraisal report, required if any
  • Determines Freddie Mac purchase eligibility


Please note that Loan Prospector assesses only a loan's eligibility for sale to Freddie Mac and does not analyze compliance with laws, regulations or ordinances, or any requirements imposed by your regulator. It is possible that a loan that otherwise meets Freddie Mac's purchase standards may violate a state or local law or regulation; because of that violation, the loan would be ineligible for sale to Freddie Mac& Please consult with your legal counsel and/or a compliance services vendor to assure that your loans comply with all applicable laws, regulations, etc.
