Why this is the worst time for deficit-financed tax cuts

Mark Zandi is the chief economist at Moody’s Analytics.

I’m no fan of the tax cuts the Trump administration and Republican Congress are trying to jam into law. The cuts won’t help the economy, but they will add to the nation’s debt. Multinational corporations and wealthy taxpayers are clear winners, but it is unclear if small businesses and lower income taxpayers get much if any tax break. The tax code will be simpler for some, but more complex for others.

But I’m guessing you’ve heard all this before. These criticisms of the tax cuts have been well articulated and debated. I won’t rehash them. Instead, let me give you a few less-appreciated reasons why the tax cuts Washington DC is considering are a big mistake.

Lower house prices

The tax cuts will lower house prices in much of the country. Nationwide, the hit to house prices will be as much as 5%, and much greater for higher priced homes, especially in parts of the country where incomes are higher and there are thus a disproportionate number of itemizers, and where homeowners have big property tax bills. The Northeast corridor, South Florida, big Midwestern cities, and the West Coast will suffer the biggest price declines. Counties like Westchester, NY; Cook, IL, and Delaware, PA will see double-digit price declines (see Chart 1).

To connect the dots between the tax law changes and house prices consider that most homebuyers determine how much home they are able to purchase after considering the tax breaks they will receive as homeowners. For those who itemize on their tax returns, this includes the mortgage interest deduction and property taxes. Current house prices thus reflect the value of these tax breaks. In reality, homebuyers don’t do this calculation, but Realtors and mortgage lenders do it for them.

The tax cuts being considered by Congress significantly reduce the value of the mortgage interest deduction by doubling the standard deduction and thus significantly reducing the number of households that itemize and thus take advantage of the mortgage interest deduction. Property tax deductions are also scaled back or eliminated under the tax cut proposals. Also weighing on house prices will be the lower housing demand due to the higher mortgage rates that result from the higher federal budget deficits and debt under the tax cuts.

None of this is to say the mortgage interest and property tax deductions lift homeownership—a selling point others give for these tax breaks. Moreover, prices for lower priced homes in some parts of the country, particularly in more rural and exurban areas where incomes are lower and itemizing less commonplace, should rise modestly if the tax proposals become law.
