BSI was founded in 1986 in Pennsylvania. Over the years, the company has originated, audited and serviced several billion of dollars mortgage loans. With the success attained in offering these services to clients, BSI was ranked as a Tier 1 servicer by Freddie Mac and Superior by Fannie Mae for servicing quality.

Until 2005, BSI operated as the mortgage group of a bank based in Indiana. In 2006, an investor group acquired BSI from its parent bank and transformed it from a lender and servicer into an exclusive service provider and outsourcer to its clients. It does not originate or service mortgages on its own account.

In 2007, BSI acquired the outsourcing division of The SRS Group, one of the largest loan due diligence and quality control firms in the industry. BSI today serves over 180 clients ranging from Wall Street securitization group to banks, credit unions and mortgage bankers.
