Key Points
The S&P Cotality Case-Shiller national index rose 2.1% in the 12 months through August, up from 1.9% in July, Dean Seal reports.
After inflation, home values fell for the 15th straight month. August's inflation ran about 1.3 percentage points above the home-price gain.
Chicago led the 20 cities for the sixth month in a row at 6.7%. New York rose 6.2% and Cleveland 4.3%. Seattle fell 2%, the biggest decline for a third month.
S&P's Rebecca Kaufman called affordability 'challenging,' citing inflation at 3.4%, Brent crude near $100 a barrel and mortgage rates she put in the mid-to-high 6% range.
The Journal's own table is tougher on rates. Bankrate's 30-year fixed sat at 7.35% on Tuesday and Freddie Mac's weekly survey at 7.32%.

A 2.1% gain sounds fine. Inflation ran about 1.3 points faster, so the house lost ground in real terms.
In one line: Home prices rose 2.1% but fell after inflation for the 15th straight month, so treat your house as shelter first and an investment second.
Home prices rose 2.1% in a year. Good news, on paper. Then check the price of everything else. Inflation ran about 1.3 percentage points faster than home prices in August. So the average American house lost ground in real terms. That's 15 months in a row.
The numbers come from the S&P Cotality Case-Shiller national index, reported by the Journal's Dean Seal. It rose 2.1% in the 12 months through August. July's gain was 1.9%, so the pace picked up. Rebecca Kaufman of S&P Dow Jones Indices noted the real gap narrowed as nominal growth got stronger. She still called affordability 'challenging.' Her list is familiar. Inflation at 3.4%. Brent crude near $100 a barrel. Mortgage rates she put in the mid-to-high 6% range.
That last figure is kinder than the Journal's own tables. Bankrate's 30-year fixed rate sat at 7.35% at Tuesday's close. Freddie Mac's weekly survey put it at 7.32%. We'll report the quote as given. We'd budget off the table.
Chicago up, Seattle down
The map matters as much as the average. Chicago led the 20 cities for the sixth month in a row, up 6.7%. New York rose 6.2% and Cleveland 4.3%. Seattle fell 2%, its third straight month as the biggest decliner. Two homeowners can read the same headline and live in different markets. One is beating inflation. The other is losing to it twice.
Our read
This is housing (M6). The lesson is old. The data keeps teaching it anyway. A house is shelter first. It's an inflation hedge second, and a shaky one in some years. For 15 months the national number has trailed the cost of living. Add property tax, insurance, upkeep and a 7.35% mortgage, and the 'return' on a home gets thin. None of that makes owning wrong. It makes counting the house as your growth engine wrong. Retirement math that leans on the home rising 5% a year needs a second look. The story names no holding of ours. Two homebuilders, D.R. Horton (DHI) and Lennar (LEN), sit in one book each. Nothing added.
The one thing in your plan this touches is the number you've written down for your home's value and growth. The check this week is to open the plan and find that line. If it assumes the house beats inflation every year, change it to flat after inflation and see what else has to move. It's easier to find the leak on a dry day.
What It Means For Your Portfolio
Hold. Count the house as shelter first and growth second
No portfolio action. No house holding is named in the story; the planning point is the growth rate you assume on your home.
General planning principles, not advice for anyone in particular. In a retirement projection, model the house at zero real growth. If it does better, that's a bonus. Keep the growth engine in diversified investments and the roof in the shelter column.
If you're buying now, run the payment at 7.35% and the first few years at flat real value. A home that pencils out on those terms is a home you can keep.
