Inventory Is Up. New Construction Is Down 38 Percent. Only One of Those Lasts.

Here is the number everyone is repeating this month. Home sales rose 7 percent in July, the strongest annual gain of 2026, according to Zillow's July Market Report. Pair that with for-sale inventory that keeps climbing off its 2021 lows, and the story writes itself. The buyer finally has room to breathe, and Southeast Michigan has settled into a calmer, better-supplied market. That read is half right, and the half it misses is the one that decides where prices go next.

There are two kinds of inventory, and the market treats them as if they were the same thing. They are not.

Borrowed Supply Versus Built Supply

The inventory improving right now is mostly borrowed. It is existing owners who finally decided to list, homes changing hands inside a fixed pool of houses. That kind of supply expands and contracts with rates and sentiment, and it can reverse in a single quarter. Built supply is different. It is new homes added to the total stock, and it is the only thing that permanently loosens a tight market. On that measure Southeast Michigan is heading the wrong way. New residential construction permits filed in Detroit are down roughly 38 percent year over year through mid-July, and Michigan's own statewide housing plan through MSHDA puts the shortage in the tens of thousands of homes a year. We are not building our way out of anything. We are trading the same houses back and forth.

The Pipeline Is Already Flattening

Watch the leading indicator, not the headline. That 7 percent sales gain reflects contracts signed weeks earlier, when the 30-year fixed was still in the low 6s. Since then rates have climbed to roughly 6.74 percent as of mid-August, the highest in more than a year, and newly pending listings are up just 0.3 percent from last year. Zillow flagged that the pipeline of future sales is running dry. So the closings look strong while the fuel behind them thins out. Layer the permit slowdown on top of that, and today's selection starts to look like a window rather than a floor.

How to Play a Market That Is Looser Than It Will Stay

• •Judge the market by your own city and price band, not a national sales headline.
• •Separate borrowed supply (owners listing) from built supply (new construction) when you hear that inventory is up.
• •If you are buying, treat the current selection and negotiating room as a window a rate cut can close.
• •If you are selling, compete on preparation and honest pricing, not on hope that scarcity carries a weak listing.
• •Watch permits and pending listings, not just closings, if you want to see the next move before it reaches prices.

The national feed will keep telling you inventory is up and the pressure is off. In a region that is not building enough homes to meet its own demand, that comfort has a shelf life.
