Cooperatives or “affinity groups” are keeping quiet on what effect recent changes made by Fannie Mae regarding volume discounts will have on their businesses. To date, the three most widely recognized lender co-ops – Capital Markets Cooperative, Lenders One, and America’s Mortgage Cooperative – have said little or nothing on the situation, at least publicly. However, mortgage bankers close to the issue say it could affect Lenders One the most since the company once promoted a pricing advantage it enjoyed as a marketing tool. Some cooperatives charge members for their services upfront, while others only receive a percentage of the value derived from each secondary market transaction.
