Going-In Cap Rate vs Exit Cap Rate

The going-in cap rate vs exit cap rate comparison is central to commercial real estate modeling: the cap rate at acquisition (going-in) and the cap rate assumed at sale (exit) drive the investor’s hold-period return. If market cap rates fall during the hold period, the exit cap rate is lower, expanding returns. If they rise, returns compress.

Why Cap Rates Differ at Entry and Exit

A property purchased at a 5% cap rate will not be sold at a 5% cap rate unless the market yield for comparable properties remains unchanged. In reality, cap rates shift over time due to changes in interest rates, property risk, market sentiment, and competition for deals.

The going-in cap rate is the yield the investor accepts at purchase: the net operating income divided by the acquisition price. If a property generates $1 million in annual NOI and is purchased for $20 million, the going-in cap rate is 5%.

The exit cap rate is the assumed yield at sale, typically modeled to differ from the going-in rate. If the property is projected to sell at a 4.5% cap rate, the valuation is higher (same $1 million NOI divided by 4.5% = $22.2 million), generating a capital gain beyond the NOI-driven appreciation. If the exit cap rate is 5.5%, the sale value is lower ($18.2 million), eroding returns.

The cap rate spread—the difference between going-in and exit—is a key driver of total return. It is not mere noise; it represents the investor’s bet on market conditions at exit.

Cap Rate Compression: The Bullish Scenario

When cap rates fall during the hold period—often due to declining interest rates, economic stability, or increased investor demand for the asset class—the exit cap rate is lower than the going-in rate. This is cap rate compression, and it amplifies investor returns.

Example: A property is purchased at a 6% cap rate for $10 million, generating $600,000 annual NOI. The investor models:

• Holding period: 5 years
• NOI growth: 3% annually (compound)
• Exit cap rate: 5% (compression of 100 basis points)

After 5 years, NOI grows to $695,500. Under the exit cap rate of 5%, the sale price is $13.91 million ($695,500 ÷ 0.05). The capital gain is $3.91 million, split between NOI growth appreciation ($1.1 million) and cap rate compression ($2.8 million). Cap rate compression alone drives most of the return in this scenario.

This dynamic explains why investors are willing to accept lower yields (higher prices, lower cap rates) on quality properties during economic expansions. They expect cap rates to remain low or compress further, driving capital appreciation beyond rental growth.

Cap Rate Expansion: The Risk

Conversely, if cap rates widen during the hold—due to rising interest rates, recession, or reduced investor confidence—the exit cap rate is higher than the going-in rate. This is cap rate expansion, and it reduces or eliminates capital gains.

Example: The same property is purchased at 6% cap rate for $10 million. But the investor models an overly optimistic exit cap rate of 5% and fails to account for rising interest rates during the hold period. Upon exit, cap rates have moved to 7% due to higher mortgage rates. The same $695,500 NOI is now valued at only $9.93 million ($695,500 ÷ 0.07). The investor has suffered a capital loss of $0.07 million despite 3% annual rental growth.

This risk is real. An investor who buys at a low cap rate in a low-rate environment may face cap rate expansion if rates rise, offsetting any NOI gains. The longer the hold period, the greater the exposure to cap rate shifts.

Modeling the Exit Cap Rate: Conservative Practice

Professional investors do not assume the exit cap rate will match the going-in rate. Instead, they model it conservatively—usually assuming cap rate expansion of 25–100 basis points from the going-in rate. This is a margin of safety.

A disciplined model might look like this:

• Purchase at 5% going-in cap rate
• Assume 5.25% exit cap rate (25 bps expansion)
• Model NOI growth at 2.5% annually

The 25 bps cushion accounts for the possibility that cap rates will normalize upward after a period of compressed rates, or that the market appetite for the property type will decline slightly. If cap rates actually compress, the investor outperforms the model. If they expand less than 25 bps, the investor still delivers acceptable returns.

Conversely, an aggressive investor might assume exit cap rate equals going-in cap rate or even compression, banking on continued favorable market conditions. This can work but carries execution risk.

Market Context and Cap Rate Dynamics

The relationship between going-in and exit cap rates depends on market environment:

• Low-rate environment (2010–2021): Cap rates were historically compressed. Many investors assumed further compression or flat rates at exit, achieving strong returns when that assumption held. Those who did not account for rising rates suffered in 2022–2024.

• High-rate environment (2024+): Investors assume higher cap rates at entry and may project further expansion at exit, leading to conservative returns and lower sale prices.

• Recovery periods: As markets stabilize after a downturn, cap rates may compress naturally as investor risk appetite returns, creating outsized returns for value investors who buy at peak-spread cap rates.

The exit cap rate assumption is not a forecast of the future; it is a disciplined assumption that reflects the investor’s risk tolerance and market view. A value investor assumes expansion (conservative); a growth investor may assume compression (bullish).

Impact on Total Return and Investment Decision

The going-in cap rate vs exit cap rate spread is not an academic detail—it is the difference between a deal’s success and failure. A property purchased at 6% with 3% annual NOI growth looks weak if the exit cap rate is 8% (expansion). The same property looks strong if the exit cap rate is 4.5% (compression). Both are the same property; the only variable is market cap rates at exit.

This is why commercial investors spend significant effort on cap rate forecasting. Some rely on historical ranges; others monitor bond yields and mortgage rates, linking them to cap rate spreads. The best investors recognize that cap rates are mean-reverting—they drift toward historical averages over time—and structure hold periods around those cycles.

Stress Testing and Sensitivity Analysis

Professional underwriting includes sensitivity tables showing returns under different exit cap rate scenarios. A model might show:

This table clarifies that the deal’s viability depends on cap rate trajectory. If the investor can only tolerate a 1.2× equity multiple (6% IRR), the deal only works if cap rates compress or remain stable. If cap rates expand to 6%, returns disappoint. Institutional investors and lenders use this analysis to define acceptable ranges and downside limits.
