Analytics firm Interthinx plans to launch the Equifax (EFX) undisclosed debt monitoring system as part of its service. The debt monitor detects new debts issued to borrowers during the  critical 30-to-45 day quiet period of the loan application cycle. From the time a loan application is filed to its closing, underwriters are generally unable to detect new debts issued to the applicant during the extended quiet phase. This often leads to a situation where loans are approved without the appropriate level of scrutiny, the firms contend. To help financial institutions with these undisclosed risks, analytics firm Interthinx plans to incorporate the Equifax undisclosed debt monitor into its FraudGUARD technology. The incorporation of the system will allow Interthinx clients an opportunity to obtain instantaneous updates on every new debt listed under a loan applicant’s name. So if a borrower obtains an auto loan while waiting approval on a home loan, the system will notify the underwriter, giving them a realistic portrait of the borrower’s financial commitments. “Our research shows that $43 million in auto loan payments were potentially overlooked during mortgage underwriting in the first three quarters of 2010. Through our relationship with Interthinx, we have made it easier than ever before for mortgage lenders to access unique industry solutions that help them identify this type of hidden debt,” said Steve Meirink, Equifax mortgage growth initiatives leader. “Teaming with Interthinx, a proven leader in mortgage fraud detection, has created another way for financial institutions to make better underwriting decisions.” Write to Kerri Panchuk.
