What is a good cap rate for self-storage?

Stabilized institutional assets in the top 50 MSAs have been trading around 4% to 5% caps, with secondary markets close behind. But the cap rate is the output of NOI and price — underwrite the inputs, not the number.

Why are self-storage cap rates so low?

Self-storage is a safe, predictable asset, and institutional money is paying for that safety and scale in top metros. Low caps reflect confidence in the asset class, not a bargain.

How do you calculate a cap rate?

Cap rate is net operating income divided by price. Change either input and the cap rate changes, which is why it's an output, not a target you set.

Is a higher cap rate better?

Not by itself. A higher cap usually means higher risk or softer NOI. A 5% cap on an NOI that's real and growing beats an 8% cap on an NOI about to shrink.

Do cap rates differ between cities?

Yes. Top-50 MSAs run 4% to 5% for stabilized assets, with secondary markets not far behind. The gap between metros is where the invisible empire lives.

Cap Rate Is an Output, Not an Input. What the Current 4-5% Range Tells You

The trap is buying the cap rate

Here’s the phrase that loses people money: “I want to buy at a 6 cap.” Cap rate is an output, not an input. You do not buy a cap rate. You buy an NOI at a price, and the cap rate is what that math spits out. Lead with the cap rate and you will buy the wrong deal every time.

What the current range actually says

StorageCafe’s July 2026 read: stabilized institutional assets in the top 50 MSAs are trading around 4% to 5% caps, and secondary markets sit not far behind. That is a market paying top dollar for safety and scale. It tells you what money thinks of self-storage as an asset class. It tells you nothing about a specific facility — its rent roll, its tax line, its deferred maintenance. Those are what decide the deal.

How a cap rate is actually made

Cap rate equals NOI divided by price. Three inputs, and every one of them can be cooked. Rent roll overstated. Expenses understated. The tax assessment never verified. Garbage in, garbage out. If the NOI is padded, the cap rate is a lie wearing a percentage.

That’s the rub. Two facilities priced at the same cap rate are not the same deal. One has a rent roll $12Kunder market, an assessment you can contest, and a roof that’s done. The other is the reverse. The cap rate doesn’t know. You have to.

Why a low cap can be a great deal and a high cap a bad one

A 5% cap on an NOI that’s real and growing beats an 8%cap on an NOI that’s about to shrink. The market already prices the difference — that’s why the 4–5% range exists. Buying the low cap is buying the quality you underwrote, not the number. Buying the high cap is buying somebody else’s problem at a discount that might not be deep enough.

Where this meets the pond

Secondary markets sitting close behind the top 50 is the invisible empire showing up in the data. The institutions want the big, safe, top-MSA assets, and they’re paying 4–5% caps to get them. The drive-up facility in the tertiary market, the one too small for them to bother with — that’s where the gap between what you pay and what you can improve still lives. You are not competing with a pension fund for that lot. That’s the point.

The bottom line

Never open a deal with a target cap rate. Open it with a rent roll, a T12, a county call, and a 35–40%expense ratio. Do the math honestly, and the cap rate will tell you what the deal is worth to you. If the number that comes back doesn’t work, the deal doesn’t work. Walk.

Cap rate is an output, not an input. Run the numbers.
