Historical NOI Versus Projected NOI Cap Rates

Both rates are one year of net operating income divided by a price. A historical NOI cap rate puts income already recorded in the numerator. A projected NOI cap rate puts in estimated income for a defined future period, usually the first year of ownership. The two answer different questions, so a rate is only comparable with another rate built on the same income period and the same price.

What changes when the numerator moves from recorded to projected income

The formula is identical in both cases: NOI divided by price. With recorded income, the result shows how the price relates to what the asset has already produced. With projected income, it shows how the price relates to what a buyer expects it to produce over a stated period.

A historical figure carries no explicit credit for upside from economic or market cycles, or for changes a new owner makes. Buyers can still weigh that upside when they set a price, so the recorded number and the price a buyer pays can drift apart.

The entry cap rate is the projected first year NOI divided by the acquisition price. The exit cap rate belongs to the other end of the hold. It is the capitalization rate expected at sale, so it prices a future buyer’s income and never describes the going-in price.

With NOI held constant, a higher price produces a lower cap rate and a lower price produces a higher one. Any gap between two rates on the same asset therefore comes from the numerator, the denominator, or both.

“It is typically the projected first year’s net operating income divided by the acquisition price. Exit Cap Rate The exit cap rate, sometimes called terminal or reversion cap rate, is the expected capitalization rate at sale.”

Hotel data on how far projected rates sat above historical rates

Going-in rates built on projected first year NOI and purchase price ran 20 to 90 basis points above rates built on historical NOI across hotel product segments. The stated reason was investor expectations of future NOI growth: when buyers price in growth, the projected numerator exceeds the recorded one at the same price.

That spread describes one comparison in one property type. It gives no conversion factor for an office building, a multifamily asset or a different hotel cycle, because the size of the gap depends on how much growth the buyer underwrites.

Historical rates carry their own context. Full-service hotels appraised at the time of sale averaged a 7.5 percent capitalization rate on historical NOI in one annual dataset. That figure belongs to its population and period and does not stand as a current market rate.

Matching the cap rate to the income basis before comparing anything

A cap rate carries the income basis of the NOI it was built on. A rate built on actual or trailing twelve month income sits beside actual or trailing NOI. A rate built on pro forma income sits beside the pro forma.

Underwriting and appraisal review checklists treat this as a consistency test: the capitalization rate should match the income basis used for the subject property.

The reason is arithmetic. A projected NOI that exceeds trailing NOI produces a higher value at any fixed rate, and a projection below trailing NOI produces a lower one. Value then moves with the basis mismatch and says nothing about the asset.

Why transaction rates and appraisal rates can sit far apart

Rates drawn from different populations can differ widely even before the income basis enters. In one quarter, office properties in an institutional appraisal database carried an average appraisal cap rate of 5.6 percent. The 23 office properties sold out of that database in the same quarter averaged an 8 percent transaction cap rate based on in-place income.

That gap reflects appraisal versus transaction pricing and held versus sold assets. The income basis adds a further layer, so the spread cannot be read as the pure effect of historical versus projected NOI.

Before treating a spread as a change in value or risk, the reader checks which NOI sits in each numerator and which price sits in each denominator.

Worked example: one $10,000,000 acquisition priced on trailing and projected income

The figures are hypothetical. A buyer evaluates a stabilized asset at a $10,000,000 price. Trailing twelve month NOI is $800,000, so the historical NOI cap rate is $800,000 divided by $10,000,000, or 8 percent.

Base case. The buyer’s first year budget adds $120,000 from scheduled rent steps and subtracts $40,000 for expense growth. Projected first year NOI is $800,000 plus $120,000 minus $40,000, or $880,000. The projected NOI cap rate is $880,000 divided by $10,000,000, or 8.8 percent, which is 0.8 percentage points above the historical rate at the same price.

Stressed case. Price and trailing NOI stay the same. Rent steps add only $40,000 and expenses grow by $80,000. Projected first year NOI is $800,000 plus $40,000 minus $80,000, or $760,000. The projected rate is $760,000 divided by $10,000,000, or 7.6 percent, which is 0.4 percentage points below the historical rate.

Now the basis mismatch. Comparable sales are assumed to support an 8 percent rate extracted from trailing income. Capitalizing the matching trailing NOI gives $800,000 divided by 0.08, or $10,000,000. Capitalizing the base case projection at that rate gives $880,000 divided by 0.08, or $11,000,000, which is $1,000,000 above the price. The stressed projection at the same rate gives $760,000 divided by 0.08, or $9,500,000, which is $500,000 below the price.

The $1,000,000 and the $500,000 come entirely from the projection, since the price, the trailing NOI and the 8 percent rate are the same in both cases. Each rate here is one year of income over price and says nothing about return over a hold.

Pitfalls and mistakes when historical and projected rates are mixed

An unlabeled rate hides its numerator. A quoted 8.8 percent and a quoted 8 percent on the same asset can both be arithmetically correct, as the example shows, and a reader who assumes both use trailing income will read a 0.8 point difference as a pricing disagreement.

Capitalizing projected NOI at a rate drawn from trailing income overstates value whenever the projection exceeds the trailing figure, and understates it when the projection falls short. In the example the same 8 percent produces values $1,000,000 above and $500,000 below the price depending only on the income basis.

A projected cap rate is an estimate and cannot be reported as realized performance. It rests on assumptions about rents and expenses for a stated period, and it changes with each of them.

A spread from one property type cannot be carried to another. The 20 to 90 basis point hotel range reflected growth expectations in that comparison, and an asset with a different income profile can show a smaller, larger or reversed gap.

Mixing populations contaminates a comparison. Appraisal rates on held assets and transaction rates on sold assets differ in who is in the sample as well as in the income basis, so their difference cannot be assigned to NOI timing.

Questions that make two cap rates comparable

Which NOI period sits in the numerator? The answer places each figure as recorded or forward looking before any comparison starts.

Is the income actual or pro forma? Trailing twelve month income counts as actual, and a rate and the income it is applied to need the same basis.

What does the denominator represent? An acquisition price and an appraised value are different measures, and the ratio changes with each.

What operating changes or market conditions bridge recorded NOI to projected NOI? The size and source of that bridge determine how far the projected rate moves from the historical one.

Does the stated rate describe entry or exit? The entry rate uses projected first year NOI and the acquisition price, and the exit rate is the expected capitalization rate at sale.

Do the compared assets and transactions share a property type and a population? A spread across unlike groups cannot isolate the income basis effect.
