A group that may be viewed as generally in favor of fewer taxes – the National Association of Home Builders – is not happy that the mortgage interest deduction could disappear in the Trump tax cuts:

That’s because one day before, House Ways and Means Committee Chairman Kevin Brady (R-Tex.) informed NAHB that he would not be including a homeownership tax credit as part of the new tax legislation, which will be released on Wednesday.

NAHB’s chief executive, Jerry Howard, had spent months working on this new tax provision with Brady’s aides, but House leaders wouldn’t allow its inclusion, Howard was told. The next day, Howard and other NAHB officials gathered on a conference call and debated what to do. They agreed unanimously — kill the bill…

The home builders are seen as among the most influential Washington corporate forces, not only because they have members everywhere but are often big fundraisers for politicians and have a close connection to the economy, development, hiring and economic growth.

They are incensed about proposed changes to tax law that, they believe, would eliminate the need for almost all Americans to itemize their tax deductions, an adjustment they think would nullify the need for middle-class Americans to deduct their mortgage interest from their taxes. They are also incensed that the bill would strip away the ability of Americans to deduct their state and local property taxes from their federal taxable income. Both these changes, NAHB argues, would raise the cost of buying and owning a home.

This part of the tax code has been debated in recent years (ranging from fiscal cliff issues to 2010 post-housing bubble discussions). And, more broadly, the United States is the only developed country that subsidizes mortgages in the ways that we do.

It is not a surprise that certain interest groups would oppose changes to the tax code that they perceive could affect their business. At the same time, any perceived effect on housing – not only a major part of the economy but also symbolically important as a marker of the middle-class lifestyle – is going to draw a lot of attention. And this area also involves the interests of fairly wealthy Americans:

But this national wealth-creation policy has several negative side effects. Since tax benefits are most useful for people with taxable income, U.S. wealth-creation policy is predominantly for people who already have wealth. These high-income households don’t consider their tax benefits to be a form of government policy at all. For example, 60 percent of people who claim the MID say they have never used any government program, ever. As a result, rich households can be skeptical of public-housing policies while benefiting from a $71 billion annual tax benefit which is, functionally, a public-housing policy for the rich. As Desmond writes, “a 15-story public housing tower and a mortgaged suburban home are both government-subsidized, but only one looks (and feels) that way.” In short, an asset-building, wealth-creation, or welfare policy that’s run through the tax code can hurt the overall push for more direct forms of welfare—like simply giving money to the poor…

But more generally, people need money to buy houses. The United States still lags almost every advanced economy in the amount of money transferred from the rich to the poor. One major reason is that the tax code has become a vehicle for incentivizing wealth-creation among households who already have the most wealth, even as the government has soured on policies that spend money directly on the poor. It’s hard to find a better exemplar of this sorry fact than the juxtaposition of America’s affordable housing crisis and the untouchable sanctity of the mortgage-interest deduction.

In other words, the interests of the NAHB are not necessarily with the Americans who most need housing but with those who can purchase more expensive new homes. Thus, the mortgage interest deduction is just another piece of evidence regarding a bifurcated American housing market.
