The Mortgage Bankers Association released a paper focused on how the various aspects of its reform proposal could impact consumer costs and concluded any impact would be minimal.The trade group explained that costs under the MBA proposal, which calls for multiple privately owned guarantors, are likely to be similar to costs in today’s mortgage market. “While the precise impact on consumer costs from true housing-finance reform may be difficult to gauge, we know that attempts to shortcut reform through recap and release would lead to much higher costs for consumers,” said the MBA, adding that global investors have been clear that they don’t want to return to a world of implicit guarantees.
