Why Does The Mortgage-Interest Tax Deduction Still Exist?

This is the latest story in our series on money in politics.

If you have a mortgage on your home, you can deduct the interest from your taxes. It’s a popular, well-entrenched policy. But according to one policy adviser to a U.S. senator, “the mortgage-interest deduction, from a purely policy perspective … makes no sense.”

It’s a view that’s supported by a mountain of academic research: The mortgage-interest tax deduction benefits the rich more than the poor, has little effect on home ownership and isn’t even really a bargain for homeowners because it raises home prices.
