Watch out for 8% mortgage rates

The Consumer Price Index report of April 10 showed that inflation, at least at the consumer level, is more stubborn than many investors and economists had hoped.

The result was a nasty selloff in stocks as many on Wall Street and elsewhere realized that the Federal Reserve isn't going to cut interest rates in the near future and maybe not in 2024.

The selling hit just everyone nationally involved in real estate:

  • Homebuilders D.R. Horton  (DHI) , off 6.4%. PulteGroup  (PHM) , down 6%.

  • Home-improvement retailers Home Depot  (HD)  and Lowe's  (LOW) , each down 3%.

  • Online real-estate broker Zillow  (Z)  dropped 6%, and home-financial company Rocket Cos.  (RKT)  dropped 12.8%.

  • The iShares U.S. Home Construction ETF  (ITB)  slumped 4.7%. The ETF's holdings include builders, building-supply companies and related companies.

The CPI report also raised fears that mortgage rates would shoot up just as the annual home-buying season shifts into high gear.

The consensus is still that rate cuts are coming — but maybe just two cuts, says Sam Stovall, chief investment strategist at CFRA, the New York securities-research firm.

The first cut won't come until September, Stovall predicted Wednesday, with the second not landing until December.

That means there's little fuel to pull interest rates lower. The yield on the 10-year, to which mortgage rates are most closely linked, is up some 35 basis points in April.

Mortgage rates are higher because they move closely with bond yields.

Rising rates will make the buying and selling of homes more challenging as the big spring/summer buying season starts.

How high could mortgage rates go? As high as the day the 30-year rate hit 8% last October?

Maybe. It would require just about everything to go wrong:

  • A big jump in oil prices.

  • Increasing violence in the Middle East and in Ukraine.

  • A sudden loss of faith in the ability of financial regulators to regulate markets.

  • Continued pressure from U.S. financial deficits.

Negotiating the situation now

On Wednesday, the daily survey of Mortgage News Daily, which covers mortgage markets and rates offered by lenders around the country, showed 30-year mortgage rates at around 7.34%.

That was up from 7.06% on Tuesday, 6.9% on March 11 and 6.6% at the end of  December.

So let's say you're looking at paying $350,000 for a home with a 20% down payment. That means a mortgage of $280,000.

The monthly principal-and-interest payment just went up from about $1,844 on March 11 to $1,927, a change of $83 a month. That's $996 a year, or a 4.5% increase.
