Exit Cap Rate: The One Assumption That Moves Everything
The exit cap rate — also called the terminal or reversion cap rate — is the capitalization rate a model assumes the property will sell at when the hold ends. Divide the projected final-year NOI by the exit cap and you get the sale price that drives most of a deal's projected profit. Which makes it the strangest number in the model: the single largest driver of the IRR, and the one nobody can actually know.

This guide is for sponsors and GPs who have to write that number down and defend it — to a lender's credit committee, to a sophisticated LP, and eventually to reality. The discipline isn't in predicting the future; it's in choosing an assumption that doesn't require the future's cooperation.
Why one small number dominates the model
The sale usually accounts for the majority of a value-add or development deal's total profit, and the exit cap sets the sale price. Because the cap rate sits in the denominator, small moves produce violent swings in value — a property with $1,000,000 of exit NOI is worth $20 million at a 5.0% exit cap and $18.2 million at 5.5%. That half-point of assumption just moved $1.8 million of investor money.
The asymmetry that matters
Every basis point of exit-cap optimism flows straight to the projected IRR without changing anything real about the deal. It is the cheapest possible way to make a model look better — which is exactly why experienced investors check it first.
This is the first place a sophisticated LP looks in a pro forma, for a simple reason: rents, expenses, and budgets are all somewhat verifiable in diligence. The exit cap is pure assertion. How a sponsor sets it tells the investor how the sponsor treats every number they can't be checked on.
How disciplined sponsors set the exit cap
- Start from today's market cap rate for the stabilized version of the asset, supported by actual comparable sales — not from the cap rate that makes the deal work.
- Expand it for time: the convention is to add roughly 5–10 basis points per year of hold (a 5-year hold might exit 25–50 bps above today's cap). This builds in humility about rate cycles and asset aging.
- Never assume exit-cap compression. Modeling a lower cap at sale than at purchase means underwriting that the market will bail out the deal — if compression happens, let it be upside, not the plan.
- Sanity-check the implied exit price per unit or per square foot against replacement cost and today's comps. An exit price far above replacement cost invites the question of why a buyer wouldn't just build.
- Cross-check against the going-in cap: exiting below your entry cap on an older, shorter-remaining-life asset needs an explicit story (submarket repricing, asset transformed by the plan) — 'our renovation is nice' is not one.
- Stress it: show returns at +50 and +100 bps. If the deal only returns capital at the base-case exit cap, the deal is a bet on the exit cap.
Exit cap vs. going-in cap: reading the relationship
| Relationship | What it implies | When it's defensible |
|---|---|---|
| Exit above going-in | Conservative: value must come from NOI growth, not repricing | The default posture — most institutional models |
| Exit equal to going-in | Neutral market; plan carries the returns | Short holds, stable submarkets |
| Exit below going-in | Assumes the market pays more per dollar of NOI later | Rarely — genuine asset transformation or documented submarket shift |
The relationship is a one-row summary of the sponsor's honesty. A deal underwritten from a 5.5% going-in to a 4.75% exit is claiming, in effect, that the buyer at exit will accept meaningfully less yield than you demanded at entry. Sometimes there's a reason. Usually there's a fundraising deadline.
Note the interaction with the hold period: longer holds compound both NOI growth and exit-cap uncertainty. A 10-year model with a flat exit cap isn't conservative just because the hold is long — a decade is enough time for an entire rate cycle, which is precisely what the per-year expansion convention is trying to respect.
Presenting the exit cap to investors
In the deck and PPM, the exit cap deserves its own line, not a footnote: state the assumption, the comp support for today's cap, the expansion you applied, and the sensitivity table around it. Pair it with the projected sale price per unit so investors can gut-check it against the market they know.
- Show the sensitivity grid (exit cap × rent growth is the classic two-axis table) — it converts your biggest unknowable into a visible risk range.
- If your base case assumes any compression, disclose it explicitly and explain why — burying it is the kind of omission that surfaces in LP diligence and damages the whole raise.
- Remember these are forward-looking statements in a securities offering: label them, keep the basis reasonable, and let the disclaimer do its job. Accuracy and defensibility protect you more than optimism ever will.
Frequently asked questions
What is an exit cap rate?
The exit (or terminal/reversion) cap rate is the capitalization rate a financial model assumes the property will sell at when the hold period ends. Projected final-year NOI divided by the exit cap gives the assumed sale price — typically the largest single component of a deal's projected profit.
Why does the exit cap rate matter so much?
Because it sits in the denominator of the sale-price calculation, small changes swing value dramatically: $1M of exit NOI is worth $20M at a 5.0% cap and about $18.2M at 5.5%. A sponsor can add multiple points of projected IRR just by shaving the exit cap — which is why investors scrutinize it first.
Should the exit cap rate be higher or lower than the going-in cap?
The conservative convention is higher — commonly expanded by roughly 5–10 basis points per year of hold — so returns must come from executing the plan rather than from the market repricing the asset. Underwriting a lower exit cap than entry assumes cap-rate compression, which most institutional underwriting standards treat as speculation.
What's the difference between exit cap rate and terminal cap rate?
Nothing — 'exit cap,' 'terminal cap,' and 'reversion cap' are interchangeable terms for the cap rate applied to projected NOI at sale. 'Going-in cap' refers to the cap rate at purchase.
How do investors evaluate a sponsor's exit cap assumption?
They compare it to the going-in cap (expansion is conservative, compression is a red flag), check the comp support for today's market cap, look for a sensitivity table showing returns at +50/+100 bps, and gut-check the implied exit price per unit against comps and replacement cost. A deal that only works at the base-case exit cap is a bet on the exit cap.
