The Loan Guaranty Service is the program that helps veterans obtain housing by guaranteeing their Department of Veterans Affairs (VA) home loans and other housing related programs to help buy, build, repair, retain, or adapt a home. The service has processes to assist veterans who are behind on their mortgage, or to penalize a servicer that is not following protocol. The service also ensures that lenders are not making bad loans by requiring a too-strict quality control and review process. For more information, visit Military.com's VA Home Loan section.
