Which Which States Benefit Most from the Home Mortgage Interest Deduction?

"Earlier this week, we reported that the Trump administration may consider reducing the cap on the home mortgage interest deduction from a maximum of $1 million acquisition debt to $500,000. We estimated that this proposal could raise as much as $95 billion to $300 billion over the next decade, depending on how the cap is structured. We also found that the tax increase would primarily fall on high-income taxpayers because they are more likely to own larger homes and have more mortgage debt. Middle- and lower-income taxpayers would be much less likely to face a tax increase.
Changes to the home mortgage interest deduction would also impact certain parts of the country differently. There is a large degree of geographic disparity in who claims the mortgage interest deduction. . . a map that shows the average deduction amount taken per tax return, or the total amount of home mortgage interest deducted in a state divided by the number of tax returns in a state.
Two primary factors influence how much home mortgage interest is deducted in a state: state housing prices and state income levels.
Regional housing prices directly impact mortgage interest payments . . .
Income levels also impact the amount a state claims in mortgage interest. Higher-income taxpayers are more likely to purchase larger homes and have more mortgage debt . . . "
