What Cap Rate Compression Means
Cap rate compression means market cap rates decline. Because value equals NOI divided by cap rate, the same income supports a higher indicated value when buyers accept a lower yield.
Expansion is the reverse: cap rates rise and the value supported by a given NOI falls. Investors often call the difference between the purchase cap rate and assumed sale cap rate the exit cap spread.
A Simple Compression Example
Property Value = Net Operating Income / Cap Rate
A property producing $100,000 of annual NOI indicates a $1.67 million value at a 6% cap rate. At a 5% cap rate, the same NOI indicates $2 million. That $333,000 difference comes from the market yield assumption, not additional property income.
The formula also shows the risk. If the exit cap rate rises to 7%, the indicated value falls to about $1.43 million even if NOI remains unchanged.
What Can Move Cap Rates
- Interest rates and the return available from competing investments.
- Expected rent growth, local supply, vacancies, and tenant demand.
- Property type, location, lease quality, age, and capital needs.
- Availability and cost of debt and equity capital.
- Investor risk appetite and the volume of buyers competing for assets.
Underwrite Exit Cap Rates Conservatively
Do not assume compression simply because it improves the projected return. Many investors model an exit cap rate equal to or higher than the entry rate, then check whether NOI growth can support the sale value.
Run several combinations of future NOI and exit cap rate. This separates value created by operations from value that depends on market pricing and makes the downside visible before you invest.
Frequently Asked Questions
Is cap rate compression good for property owners?
It can raise the market value supported by a given NOI, which benefits an owner selling or refinancing. Buyers receive a lower income yield at the higher price, and future expansion remains a risk.
What causes cap rates to compress?
Common drivers include cheaper capital, strong buyer demand, improving growth expectations, limited property supply, and lower perceived risk. The mix varies by market and property type.
How should I choose an exit cap rate?
Use market evidence for comparable properties, account for the building age and expected condition at sale, and test a range. Avoid relying only on a lower exit cap rate to make the projected return work.
