Weekly Inflation Outlook: Not Worried About House Prices

 | Jul 25, 2022 04:49AM ET

  • Higher mortgage rates historically associated with higher house price growth
  • Buying a real asset with levered, tax-advantage loans is still a good idea 
  • This week we will see an acceleration in money velocity when Q2 GDP is reported.
  • There is a lot of data this week, but of those, there are really two bits of information that are illuminating at some level on inflation.

    First, we will get a number of housing-related indicators. There is a huge debate at the moment between people who have a 15-year memory and expect home prices to collapse as the economy slows, and people who have a 50-year memory and expect home prices to continue to do pretty well as inflation supports the nominal prices of real assets.

    I am a dinosaur, or an elephant, or an elephantine dinosaur, and I have a long memory. I also lived and traded inflation markets through the 2007-2009 collapse; so I remember very poignantly how unique that period was. Count me in the camp that expects home prices to decline in real terms, but not in nominal terms.

    Naturally, increases in mortgage rates have a dampening effect on home-buying traffic and home sales. Increasing the monthly mortgage payment by 40% will price some buyers out of the market. But the important thing to say is that rational buyers will still buy, unless they actively expect home prices to underperform inflation for an extended period of time. Here’s why:

    If I can buy a product that is growing at the rate of inflation—as home prices do, over long periods of time, and finance that at less (after tax) than the rate of inflation, then it’s a win.

    Suppose a home buyer is taxed at the top marginal tax rate of 37%, and gets a 5% mortgage with 20% down on a $500,000 home. Then the homeowner will break even—ignoring property taxes, but also ignoring the value of the home as a place to live—if this is true:

    Rise in home equity = after-tax mortgage cost

    Home value today * expected inflation = (1-tax rate) * 5% * financed amount 

    $500,000 * expected inflation = (1-0.37) * (5% * $400,000)

    $500,000 * expected inflation = $12,600

    Expected inflation = $12,600 / $500,000

    Expected inflation = 2.52%

    Ergo, even if inflation falls to the Fed’s target level, and home prices do no more than keeping up with inflation, the homeowner still breaks even on the investment portion of the home ownership decision.

    Yes, that’s not as attractive as it was a year ago. Here’s a handy little chart showing inflation breakevens from TIPS (using the Enduring Investments’ derived real yields series prior to 1997) and from home ownership. I always use the top tax bracket, and assume the home is 80% financed at the 10-year Treasury rate + 2%.
