In 1965, William Spencer began his career as Loan Officer for Bankers Mortgage Company, based in Sacramento, California. There he had the opportunity to work with and learn from Ray Lapin, who later became the first Director for the Federal National Mortgage Association (Fannie-Mae). Spencer was a leading mortgage banker in the firm within two years.

In 1970, Spencer opened his own mortgage banking firm, Sutter Mortgage Corporation. Before long he was closing an average of 200 loans per month, specializing in spot loans, forward takeout commitments and subdivision construction . He trained loan officers and processors; was the underwriter for all loans and granted the unusual authority by FNMA, FHMC, FHA & VA to fund his own loan approvals immediately from his desk. He merged this firm with a national bank.

In 1980, in the San Francisco Bay Area, William Spencer Financial was founded and Spencer began arranging financing for commercial, industrial and agriculture real estate with private, institutional and Small Business Administration (SBA) funds; selling and purchasing loan portfolios for banks and arranging their participations. Today, he continues to offer exceptional solutions to almost any real estate loan request, assisting both large and small clients with simple and complex projects, with maximum effort to search out and obtain the very best financing and conditions for each and every loan request.

Spencer taught real estate finance and economics at the university level for many years and also conducted numerous private seminars for Banks, Realtors and individual investors. He is a real estate broker licensed by the state of California.
