What Cap Rate Means (Simple)
Cap rate is one of those terms that sounds more complicated than it is. In plain English, it is the yearly return a commercial property would generate if someone bought it with cash. The math is straight forward: net operating income divided by purchase price. A building that throws off $100,000 a year in NOI and sells for $1.25 million has an 8 percent cap rate.
What makes cap rate useful is the quick comparison it gives across very different buildings. An industrial flex property near M-59 in Shelby Township and a small retail strip in downtown Rochester might look nothing alike, but their cap rates put them on the same scale. Lower cap rates mean the market sees the property as safer or more desirable, so buyers pay more per dollar of income. Higher cap rates mean more perceived risk or more work ahead, and the price reflects that.
In the Rochester and Macomb County market, cap rates swing a lot by product type. Newer single tenant net lease buildings on Rochester Road with a national credit tenant often trade in the 6 to 7 percent range. Older multi tenant flex properties along the Van Dyke corridor or near Hall Road usually price closer to 8 to 9, and aging value add industrial in Warren or Roseville can push past 10 when vacancy or deferred maintenance is in the picture. The cap rate tells a buyer at a glance where a deal sits on that risk spectrum.
A common trap is treating cap rate like a score. It is not. Two 8 percent cap properties can look identical on paper and behave completely differently. If one has a tenant with a lease expiring in eight months and a roof that is twenty years old, the real return after a release and a capital project can be far lower. If the other has a long term tenant with scheduled rent bumps and a new HVAC system, the same cap rate is far more durable. The number is only as good as the income behind it.
Michigan buyers should also remember that the property tax line inside NOI will change when the building sells, because taxable value uncaps at transfer. A seller’s tax bill might be $22,000 because the value has been capped for years, while the buyer’s first full year could be $34,000. TDG Commercial rebuilds pro formas using the buyer’s expected tax basis so the cap rate reflects what the owner will actually experience.
Anyone comparing commercial real estate across Rochester MI and Macomb County benefits from talking through cap rates with someone who knows the submarkets. TDG Commercial, a group of top commercial realtors in Rochester MI, walks owners and buyers through the numbers behind the number and points out where the real risk sits.
Cap rates also move with interest rates. When lending rates climb, cap rates tend to follow because buyers need higher returns to cover higher debt costs. The opposite happens in a low rate environment. Investors watching the Rochester and Macomb County market over the last few years have seen cap rates widen across most product types, which has pushed prices down from the peak levels of a few years ago. That is actually good news for buyers with capital ready to deploy, because deals that did not pencil before are starting to work again.
One final note on cap rate. The figure used in a pro forma should reflect market cap rates today, not what cap rates were when the seller bought the building. A seller who purchased five years ago at a 6 percent cap cannot price the building the same way if the current market is trading at 8. TDG Commercial uses recent Macomb County comps to set a realistic cap rate assumption, which protects buyers from overpaying and helps sellers price correctly the first time instead of sitting on the market and chasing the price down.
