The National Association of Home Builders says it's open to changes to the mortgage-interest deduction — a major policy shift that could have significant implications for the Trump administration's proposed tax reform, Politico's Lorraine Woellert reports. The break benefiting homebuyers was preserved as part of the tax framework released last week, but the reform plan also calls for increasing the standard deduction, a shift that would make the mortgage interest deduction less valuable. The National Association of Realtors last week criticized the administration's plan, even though it left the mortgage tax break in place. "This proposal recommends a backdoor elimination of the mortgage interest deduction for all but the top 5 percent who would still itemize their deductions," the group's president said.
