This financial arrangement allows smaller institutions to originate mortgages that are then purchased by larger entities. Smaller banks or credit unions, lacking the capital or infrastructure to hold a large portfolio of loans, can still offer mortgage products to their customers. The originating institution processes and underwrites the loan, then sells it to a larger entity that handles servicing and assumes the financial risk. An example includes a community bank originating a loan for a local homebuyer and subsequently selling that loan to a larger national mortgage lender.
This system provides several advantages. It expands access to mortgage credit, particularly in areas where larger lenders may not have a significant presence. It allows smaller institutions to generate income from loan origination without tying up capital. Historically, this model has been crucial for supporting the housing market and facilitating homeownership across diverse geographic regions and demographic groups. It allows for focused local expertise during the origination process, while leveraging the resources of larger organizations for long-term management.
