Home loan Residential Security Maps were developed in the early 1930s by a New Deal (federally-sponsored) corporation established for the purpose of home refinance. The Home Owners' Loan Corporation created by the Roosevelt administration was initiated to prevent home foreclosure in the United States. Though the actual agency was not liable for "redlining" it did provide regulatory structure for racial bias in the private mortgage industry. A common definition of redlining states that it is the practice of denying or limiting financial services in certain neighborhoods based on racial or ethnic composition without regard to applicants’ creditworthiness. It refers to the red line (red frame) used to mark communities where financial institutions were not likely to invest. HOLC was a part of the Federal Housing Administration’s portfolio.
