Going-in versus exit cap rate

Also called Terminal cap rate, Exit cap, Reversion cap rate.

The going-in cap rate is year-one NOI divided by the purchase price. The exit or terminal cap rate is the rate applied to the forward NOI at the end of the hold to estimate the sale price. The spread between them is one of the largest and least evidenced assumptions in any underwriting.

How it works

The convention in institutional underwriting is to exit at a cap rate 25 to 50 basis points above the going-in rate. The reasoning is straightforward: the building will be five or ten years older at sale, its remaining economic life is shorter, and assuming otherwise means assuming a buyer will pay more for an older asset in an unknown capital market. Holding the exit cap equal to the going-in cap is a real assumption that should be stated out loud, and expanding it is the conservative choice.

The second convention that matters is which NOI gets capitalised. A buyer at the end of your hold is buying the income of the year that follows the sale, so the exit value should be built on FORWARD NOI, the year after the last year you own it. Capitalising the final year's trailing NOI understates the sale price by roughly one year of growth, which on a five-year hold is not a rounding difference.

Because the sale proceeds usually dominate a levered return, the exit cap does more work in an IRR than any other single input. It deserves a two-way sensitivity against exit timing or rent growth, not a single point estimate, and the downside case should assume expansion rather than compression.

Formula

Gross sale price = forward NOI / exit cap rate
  • Forward NOI is the year after the final year of the hold, not the final year itself
  • Net proceeds subtract selling costs, typically 1 to 2 percent, and repay the outstanding loan balance
  • Convention is exit cap = going-in cap + 25 to 50 basis points, and any tighter assumption should be justified

Worked example

The exit cap, priced

Five-year hold. NOI grows to $3,497,787 in year five and $3,602,721 in year six. Going-in cap 5.40 percent.

Exit at 5.40% (no expansion)$66,717,056
Exit at 5.75% (35 bp expansion)$62,656,017
Exit at 6.00% (60 bp expansion)$60,045,350
Capitalising year-five NOI at 5.75% instead of forwardunderstates by $1,824,939$60,831,078
Value of 25 basis points at exitabout $2,610,000

Twenty-five basis points is roughly $2.6 million, which is about 13 percent of the equity in this deal. The single most consequential number in the model is the one with the least evidence behind it.

The common mistake

Exiting at the going-in cap because the deal needs it to work

When a return falls short, the exit cap is the easiest input to move and the hardest for anyone to challenge, because nobody can prove what caps will be in five years. That is exactly why it should be fixed by policy before the model is built rather than solved for afterwards. If a deal only clears its hurdle at a flat or compressing exit cap, the honest statement is that the deal requires cap rate stability, and that is a market call, not an underwriting result.
