Summary: The Department of Veterans' Affairs (VA) Loan Guaranty Program, which guarantees mortgage loans for qualified lenders, provides additional assistance to those who face financial hardship and possible foreclosure. This report discusses VA's supplemental loan servicing program. GAO (1) assesses VA's implementation of its policies and procedures for servicing troubled loans and (2) analyzes VA's measures for assessing the effectiveness of its supplemental servicing program and ability to generate meaningful data for overseeing and improving loan servicing. GAO found that the three regional loan centers it visited generally conformed with VA policies and procedures and had procedures in place to ensure that VA's loan servicing representatives complied with VA policies and procedures. Two issues affect VA's ability to effectively manage its supplemental servicing program. First, VA lacks meaningful performance measures that would allow it to accurately assess the effectiveness of its program. Second, VA's computer system has been unable to generate useful and timely management reports that regional loan center managers and headquarters staff could use to manage their supplemental loan servicing program.
