Exit cap rate stress
The exit cap rate that returns nothing to equity is the rate at which sale price, less selling costs and fixed closing items, exactly equals the debt payoff. When selling costs are a percentage of price, it equals exit NOI multiplied by one minus that percentage, divided by the debt payoff plus the fixed items. Equity can reach zero while gross value still exceeds the loan, because closing costs absorb the difference. A second, lower rate marks where equity stops getting its contributed capital back.
The cap rate that zeroes the sale check
Equity receives nothing when the sale price, less selling costs, equals the debt payoff. Price is exit NOI divided by the exit cap rate, so the rate alone sets the size of the pile. The payoff and the fixed closing items sit ahead of equity whatever size the pile turns out to be.
When selling costs are a percentage of price plus a block of fixed closing items, the break-even rate has a closed form. Multiply exit NOI by one minus the cost percentage, then divide by the debt payoff plus the fixed items. Any exit rate above that result produces a shortfall, and any rate below it leaves a positive residual.
Debt and fixed items do not move with price. Only the percentage cost does.
The payoff is the balance at the sale date, plus any prepayment charge the model includes. An interest-only loan holds the balance flat, while an amortizing loan lowers it each year, which lowers the dollars ahead of equity and raises the break-even rate. A deduction belongs in one place only: a cost counted inside the percentage cannot also sit among the fixed items.
Above the threshold the arithmetic turns negative. That figure is a closing requirement, and equity receives zero. Whether anyone funds the gap is a separate question from the sale math.
Which year of NOI gets capitalized decides what the stress measures
A cap rate is the first year of expected NOI divided by price, and the exit cap rate is the rate expected at sale. Because the definition uses the first year of expected income, a sale value capitalizes the buyer’s first year, which is the year after the closing date.
The same building can carry two rates depending on the income basis. An apartment building can show a 5.5% going-in rate and a 6% rate once rents are marked to market. An exit stress that does not say which income stream sits in the numerator leaves the reader unable to tell which of those two rates is being stressed.
A pure cap rate sensitivity holds NOI fixed and moves only the rate. A combined sensitivity moves both, and its result mixes two questions. Keeping them apart shows whether a sale fails because buyers pay less per dollar of income or because the income itself is lower.
At a fixed rate, the same equation solves for the NOI at which equity reaches zero: the cap rate multiplied by the sum of the payoff and the fixed items, divided by one minus the cost percentage. That figure translates an exit rate into an operating hurdle a property manager can be measured against.
Comparing entry and exit rates carries weight only when both use the same income definition.
Worked example: a $24 million sale that falls to a zero residual at an 8% exit cap rate
The inputs are hypothetical. Exit NOI for the first year after the sale is $1,200,000. The loan is interest-only, so the payoff at sale is $14,600,000. Contributed equity was $6,000,000, and no distributions were made before the sale. Selling costs are 2% of price, and fixed closing items are $100,000. Both cases use the same capital and the same sale date, and only the exit cap rate changes.
Base case at a 5% exit cap rate. Price is $1,200,000 divided by 0.05, which is $24,000,000. Selling costs are $24,000,000 multiplied by 0.02, which is $480,000. Price less selling costs is $23,520,000. Less the $100,000 of fixed items, that is $23,420,000. Less the $14,600,000 payoff, the equity residual is $8,820,000, which is $2,820,000 above the $6,000,000 contributed.
Stressed case at an 8% exit cap rate. Price is $1,200,000 divided by 0.08, which is $15,000,000. Selling costs are $15,000,000 multiplied by 0.02, which is $300,000. Price less selling costs is $14,700,000. Less the $100,000 of fixed items, that is $14,600,000. Less the $14,600,000 payoff, the residual is $0, and all $6,000,000 of contributed equity is unrecovered.
Between the two cases the exit rate widened by 300 basis points. Price fell by $9,000,000, which is 37.5% of the base price, and the residual fell from $8,820,000 to $0.
The threshold can be solved directly. The retained share of price is 1 minus 0.02, which is 0.98. Exit NOI multiplied by 0.98 is $1,176,000. The payoff plus fixed items is $14,600,000 plus $100,000, which is $14,700,000. Dividing $1,176,000 by $14,700,000 gives 0.08, an 8% exit cap rate.
At 8% the price is still $400,000 above the loan, since $15,000,000 minus $14,600,000 is $400,000. Selling costs of $300,000 plus fixed items of $100,000 are also $400,000, so the gap closes exactly. A comparison of price with debt alone would show a cushion that does not exist.
Capital loss starts well before the wipeout. Equity gets its $6,000,000 back only when the residual reaches that amount, so the denominator becomes $14,700,000 plus $6,000,000, which is $20,700,000. Dividing $1,176,000 by $20,700,000 gives about 5.68%. That is about 68 basis points wider than the 5% base case.
The same wipeout can come from income. At a 5% rate, the NOI that leaves zero equity is 0.05 multiplied by $14,700,000, divided by 0.98, which is $750,000. That is $450,000 below $1,200,000, a 37.5% decline, and it produces the same $15,000,000 price as the 8% case.
Basis points versus percent of the rate: how an exit cushion gets stated
An exit cushion is stated in one of two units: basis points added to the rate, or a percentage applied to the rate itself. One base case assumes a 5.75% exit cap rate with a 10% increase in the rate, applied on a straight line at 2% per year. Another description drifts the market rate up 2% per year across the first five years and describes the result as a 10% cushion to current levels. The two descriptions agree, since five annual steps of 2% reach 10%.
Basis point assumptions come in different lengths. Underwriters have used 100 to 150 basis points of expansion between purchase and sale, and in one case the market rate tightened during ownership, so the expansion never occurred. Others scale the stress to the hold, with 100 basis points over 10 years or 50 basis points over five.
Credit-focused criteria apply a wider stress. Rating criteria for conduit loans set loan-specific cap rates typically more than 200 basis points above a loan’s actual rate, and where they are not, the rate may be adjusted to keep a cushion of up to 200 basis points.
The decision test compares the stated cushion with the distance to the zero-equity rate. In the hypothetical, that distance is 300 basis points, twice a 150 basis point cushion. A deal whose underwritten expansion stops well short of its own wipeout rate has room. A deal whose wipeout rate sits inside the underwritten expansion has already priced in a loss of all equity.
The exit rate cannot be observed until the sale. Sparse transactions weaken the sales comparison approach, and shifts in rate expectations move discount rates and exit cap rate assumptions, so a single point estimate of the exit rate carries more uncertainty in thin markets.
“Our base case capitalization rate on exit already assumes a 10% increase in the rate. We do this on a straight line basis and increase the rate 2% per year.”
Zero equity at the sale differs from zero recovery over the hold
Zero proceeds at the sale means the property residual is zero. Total recovery for an investor also depends on cash received before the sale, so an investor can finish with a zero residual and still have received capital back during the hold.
A second threshold sits closer to the base case. Equity gets its contributed capital back when the residual plus prior distributions reaches that capital, so the rate solves the recovery equation using contributed equity less prior distributions. Capital loss therefore begins at a lower exit rate than the wipeout rate.
Aggregate equity and a single investor class need separate calculations. The property math ends at cash available to equity, and the partnership terms allocate it. A preferred return is an entitlement within that allocation and adds no cash to the residual.
A cap rate is one year of NOI over price on an unlevered basis. It describes pricing at a point in time and does not measure return or IRR over the hold.
Mistakes that misstate the equity wipeout threshold
Gross value above the loan balance looks like equity until the closing bridge is applied. In the hypothetical, a $15,000,000 price sits $400,000 above the $14,600,000 payoff, and selling costs of $300,000 plus fixed items of $100,000 absorb exactly that $400,000. The correct test measures cash left after every modeled deduction.
Treating the wipeout rate as the point where trouble begins overlooks the capital recovery threshold. In the hypothetical, equity stops getting its $6,000,000 back at about 5.68%, well inside the 8% wipeout rate. Between the two rates the investment returns some cash and still loses money.
A percentage increase gets confused with a percentage point increase. A 10% increase applied to a 5.75% exit rate scales the rate by a tenth and adds nothing close to 10 points. Compounding the same annual step lands slightly higher than a straight line, so the model needs to state the starting rate and the resulting exit rate.
Holding NOI flat while calling the result a cap rate stress hides how value moves. Value depends on NOI divided by the rate, so a 37.5% NOI decline at the 5% rate produces the same $15,000,000 price as the 300 basis point widening. A downside that pairs weaker income with a wider rate is steeper than either alone.
Mixed income bases make rate comparisons ambiguous. An entry rate uses projected first-year NOI over the acquisition price, and an exit rate built on a different income stream folds an income change into what looks like a pure rate change. A cap rate is a single year of income over price and does not measure return or IRR over a hold, so stacking it against a hold-period return compares unlike quantities.
A lease-up delay drains interest reserves, calls for new sponsor equity and cuts the debt that trailing income supports at refinance. A worked example traces these effects.
Checklist questions for an exit cap rate stress
Which year of NOI does the exit rate capitalize? The answer fixes the numerator and keeps cases comparable.
Does the sensitivity move only the exit cap rate? A separate line for any NOI change shows whether the result isolates pricing or mixes pricing with operations.
Which deductions sit between gross price and distributable cash? The closing bridge lists percentage costs and fixed items once each.
Is the debt figure the payoff at the sale date? Amortization and any prepayment charge change the denominator of the threshold.
Is the stated cushion in basis points or as a percentage of the rate? The unit determines the arithmetic that produces the stressed exit rate.
How far is the zero-equity rate from the underwritten exit rate? Expressed in basis points, that gap can be set against the cushion the model assumes.
At what exit rate does equity stop recovering its contributed capital? That rate is lower than the wipeout rate and marks where losses begin.
Does the threshold describe aggregate equity or one investor class? The answer shows whether the math ends at the property residual or continues through the waterfall.
