Today's banks are unabashedly international businesses which thrive on providing services and taking advantage of opportunities throughout the world. Long gone are the days of the local Savings and Loan as the provider of the community's mortgage needs. Instead, behemoths of consolidations dominate today's lending scene, thriving off of large economies of scale that make any potentially smaller competitors shutter. This change in the role of banking in the community, although the largely the product of intentional moves by the banking industry and Congress, is not without its effects on the real estate industry, particularly the residential market.
In order to explain the effect of big banks on the residential real estate market, one must understand the role of local banks prior to the expansion and consolidation of banks that led to the current situation. Until the 1980's, US mortgage lending was dominated by small local banks and Savings and Loan Associations (S&L's), local banking entities that engaged in lending and offering savings deposit accounts. Initially, S&L's were heavily regulated and restricted from offering consumer loans and investing deposits in most of the investment vehicles available in the market. The Savings and Loan model relied on a favorable treatment by the Federal Reserve to allow for an increased spread between the rate charged on mortgage lending and the rate offered on deposit accounts. S&L's also frequently managed underwriting risk with local market knowledge.
