Cap Rate vs Cash-on-Cash Return
Definition
The cap rate and cash-on-cash return answer different questions about the same property. The cap rate is net operating income divided by the property's price: the income yield of the asset itself, as if bought for cash. Cash-on-cash return is the investor's annual pre-tax cash flow after debt service (and, done properly, after recurring capital needs and entity costs) divided by the cash the investor actually invested: the yield on the investor's equity. With no debt and no other costs they are equal. With debt they diverge, and the direction depends on the mortgage constant, the annual debt payment as a percentage of the loan. If the mortgage constant is below the cap rate, borrowing raises the cash yield on equity (positive leverage); if it is above, borrowing lowers it (negative leverage), even when the property itself is unchanged.
Why it matters
Property offerings quote whichever yield looks better, and the two can point in opposite directions. When interest rates were below cap rates, debt raised cash-on-cash returns and sponsors advertised them. When rates rose above cap rates, the same debt pulled cash yields below the property's own yield, and some offerings kept paying distributions only by using investor capital or reserves. Knowing both figures for a deal, and the mortgage constant that connects them, tells an investor whether the advertised cash yield comes from the property or from the financing, and how fragile it is to refinancing.
Common misconceptions
- •Cash-on-cash is not the property's yield. It is the yield on the investor's equity after debt.
- •A loan rate below the cap rate does not guarantee positive leverage. Amortization raises the annual payment above interest.
- •Higher cash-on-cash from leverage is not free. It comes with higher risk to equity if income falls or rates reset.
- •Neither measure includes appreciation. Both are current-income yields.
- •A cash-on-cash figure that ignores fees and reserves overstates what investors receive.
Technical details
One property, four ways (price $260,000, NOI $14,252, cap rate 5.48%)
All cash: equity $260,000, cash flow $14,252, cash-on-cash 5.48%, equal to the cap rate.
70% loan ($182,000), 30-year amortizing at 7.0%: debt service $14,530 a year (mortgage constant 7.98%); cash flow minus $278; on $78,000 of equity, cash-on-cash minus 0.4%. Negative leverage.
70% loan, 30-year amortizing at 4.5%: debt service $11,066 (constant 6.08%); cash flow $3,186; cash-on-cash 4.1%. Still below the cap rate, because the constant exceeds 5.48%.
70% loan, interest-only at 4.5%: debt service $8,190 (constant 4.5%); cash flow $6,062; cash-on-cash 7.8%. Positive leverage.
Lesson: compare the mortgage constant, not the interest rate, with the cap rate.
Side by side
Numerator: cap rate uses NOI; cash-on-cash uses cash flow after debt service and, properly, capital needs and entity costs.
Denominator: cap rate uses the whole price; cash-on-cash uses the investor's cash invested, including closing costs and fees.
Financing: ignored by the cap rate; central to cash-on-cash.
Use: cap rates compare properties and set values; cash-on-cash compares the income an equity investor receives.
Questions for a levered offering
What is the loan's rate, amortization and term, and when does it reset or mature?
Is the mortgage constant above or below the property's in-place cap rate?
What happens to cash-on-cash if the loan refinances at today's rates?
Are distributions covered by property cash flow, or supplemented by reserves or new capital?
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
- Why is cash-on-cash return different from the cap rate?
- Because the cap rate ignores financing and the cash-on-cash return does not. The cap rate divides the property's NOI by its full price. Cash-on-cash divides what is left after debt payments by the investor's own cash. Debt that costs less, as a percentage of the loan each year, than the property's cap rate pushes cash-on-cash above the cap rate; debt that costs more pushes it below.
- What is the mortgage constant?
- Annual debt service divided by the loan amount. A 30-year amortizing loan at 7% has a constant of about 7.98%; at 4.5%, about 6.08%; an interest-only loan's constant equals its interest rate. Because amortizing payments include principal, the constant is higher than the interest rate, so a loan can lower cash yield even when its interest rate is below the cap rate.
- Does negative leverage mean the investment loses money?
- Not necessarily. Principal repayment builds equity, and appreciation can make the total return positive. But it means current cash yield is lower with the loan than without it, and that distributions depend more on future value.
- How do fractional platforms use leverage?
- Some finance properties to raise reported cash yields. Ark7's offering materials list 'Selective Leverage: We utilize leverage to amplify cash on cash returns', and AltStreet's Ark7 review notes the parent's return comes from financing acquisitions at rates above the properties' cap rates. Check the loan's rate and amortization against the property's cap rate before relying on a levered yield.
