Capitalization Rate
Definition
The capitalization rate, or cap rate, is a property's annual net operating income divided by its price or value. It expresses the unlevered income yield a buyer receives at that price, before financing and before any change in value: a property with $14,252 of NOI bought for $260,000 has a 5.48% cap rate. Read in reverse, value equals NOI divided by a cap rate, which is how appraisers, fund managers and lenders turn income into a valuation using cap rates observed in comparable sales. A cap rate is only as meaningful as the NOI behind it: in-place NOI from current leases, stabilized NOI after planned lease-up or renovation, and projected NOI in a pro forma give very different rates for the same price. Farmland trades at low cap rates because buyers price in long-run land appreciation and low vacancy, so much of a farm's expected return comes from value change rather than rent.
Why it matters
The cap rate is the bridge between income and value in property investing, which makes it the lever most often pulled to make a deal look attractive. A seller can raise the NOI in the numerator (stabilized or projected rather than in place, light expenses, no vacancy), or a sponsor can assume a lower exit cap rate than the purchase cap rate so the property is worth more when sold. Small changes matter: at $14,252 of NOI, moving the cap rate from 5.5% to 5.0% raises the implied value from about $259,000 to $285,000, a 10% swing with no change in rent. For fractional and tokenized property, where investors rarely see comparable sales, asking for the NOI definition and the cap rate source is the quickest way to test a valuation.
Common misconceptions
- •A cap rate is not a total return. It ignores appreciation, debt, capital spending and fees.
- •A high cap rate is not automatically a bargain. It often reflects higher risk, weaker location or shorter remaining life.
- •Cap rates on different NOI definitions are not comparable. In-place, stabilized and projected NOI give different answers.
- •Farmland cap rates are not too low to be right. Buyers price in appreciation and low vacancy; the question is whether those assumptions hold.
- •An unchanged rent does not mean an unchanged value. A move in market cap rates changes appraised value directly.
Technical details
The formula, both directions
Cap rate = NOI / price (or value).
Value = NOI / cap rate.
Example: $14,252 of NOI at a $260,000 price = 5.48%.
Sensitivity: the same NOI at a 5.0% cap rate implies $285,040; at 6.0%, $237,533.
Farm example: $42,920 of NOI on a $1,760,000 farm = 2.44%.
Which NOI is in the numerator
In-place (trailing or current): what existing leases and costs produce today.
Stabilized: after planned lease-up, renovation or rent increases; an assumption, not a fact.
Projected (pro forma): a forecast for a future year.
Market: what a typical owner would earn, used by appraisers when actual figures are unusual.
Ask which is used, and recompute on in-place NOI before comparing.
Going-in versus exit cap rates
Going-in: the cap rate at purchase, on current or first-year NOI.
Exit or terminal: the cap rate assumed for the sale years later, which sets the projected sale price.
Convention: underwriters often assume an exit cap rate at or above the going-in rate to allow for aging and market risk.
Red flag: a projection that sells at a lower cap rate than it buys at, unless clearly justified; DiversyFund's stated strategy was to renovate, raise rents and sell at a lower cap rate.
Checklist
Which NOI, for which period, with which expenses and vacancy allowance?
Where does the market cap rate come from: comparable sales, an appraisal, a survey?
How sensitive is the value to a half-point change in the cap rate?
What exit cap rate is assumed, and how does it compare with the purchase?
For farms: is the rent current local cash rent, and what costs does the landlord keep?
How investors apply the term
Investors usually apply this term by tying the definition back to the controlling documents and then asking which cash flows, rights, restrictions, or valuation assumptions it changes. A useful review looks at the term alongside fees, leverage, liquidity, reporting frequency, and manager discretion rather than treating it as a standalone concept.
The practical diligence test is simple: identify who benefits if the assumption is wrong, who has control when conditions change, and what evidence the investor receives after closing. Terms that cannot be reconciled to documents, cash movements, and monitoring data should be treated as marketing shorthand until proven otherwise.
Frequently asked questions
- How do you calculate a farmland cap rate?
- Divide the farm's annual net operating income, its cash rent plus any variable rent minus the landlord's costs such as property taxes and management, by the purchase price. A 160-acre farm renting at $300 an acre with $5,080 of landlord costs earns $42,920 of NOI; bought at $11,000 an acre ($1,760,000), its cap rate is 2.44%. Use the landlord's actual costs and current rent, not the gross rent.
- What is a good cap rate?
- There is no universal answer. Cap rates are lower for assets buyers see as safer or faster-growing (prime farmland, core urban property) and higher for riskier or slower-growing ones. A higher cap rate means more income per dollar of price, usually paired with more risk or less expected appreciation. Compare cap rates only across similar assets, dates and NOI definitions.
- Why does the NOI definition matter so much?
- Because the cap rate is a ratio, a higher NOI makes the same price look cheaper. AltStreet's Lofty review found a listing priced at $3,793,150 alongside an appraisal 'at stabilization' that assumed $268,089 of NOI, an implied 7.07% cap rate on projected rather than current income.
- How are cap rates used to value property in a fund?
- Managers and appraisers divide each property's NOI by a market cap rate to estimate value, and changes in the assumed cap rate move NAV even when rent does not change. Streitwise says its NAV rests on market capitalization rates, comparable sales, interest rates, discount rates and NOI, with independent appraisals only in certain instances.
- Does a cap rate include appreciation or leverage?
- No. It is the unlevered income yield at a moment. Total return adds the change in value, and a levered investor's cash yield depends on the cost of debt; see cap rate versus cash-on-cash return.
