Cash-on-Cash Return: The Number I Actually Look At First

What it is

Cash-on-cash return is simple: it's the cash you get back each year, divided by the cash you actually put into the deal.

Take your annual pre-tax cash flow — what's left after debt service, not before it — and divide it by your down payment plus closing costs and any day-one capital you put in. That percentage is your cash-on-cash return.

It's not the same as cap rate. Cap rate looks at the property like you paid all cash for it. Cash-on-cash looks at the property the way you actually own it — with a loan on it. That distinction matters more than most people realize.

How it plays out in retail net lease

Here's the thing about net lease retail: the cap rate tells you what the asset yields, but the cash-on-cash tells you what you yield.

If you buy a single-tenant net lease deal at a 6% cap rate and pay all cash, your cash-on-cash return is roughly the cap rate. But almost nobody pays all cash. Once you layer in financing, the math changes — sometimes a lot.

If your loan rate is lower than the cap rate, leverage works in your favor. Your cash-on-cash return climbs above the cap rate, because you're using the bank's cheaper money to buy a higher-yielding asset. That's the whole appeal of leveraged net lease investing.

But flip that relationship — borrow at a rate higher than the cap rate — and leverage works against you. Your cash-on-cash return drops below the cap rate, even though the property itself is performing fine. I've had clients get confused by this: the real estate didn't get worse, the financing did.

That's why two buyers can look at the exact same net lease property and walk away with two very different cash-on-cash numbers, just based on how they financed it.

What to watch for

• Make sure the number you're being handed is calculated after debt service, not before it — some marketing packages quietly use the unleveraged number and call it cash-on-cash.
• Ask whether the projection includes a reserve for capital expenditures, vacancy, or lease turnover. If it doesn't, the real number is lower than what's on the page.
• Year-one cash-on-cash isn't the whole story on a lease with built-in rent bumps. It generally improves over the hold as rent steps up, assuming the loan payment stays fixed.
• Watch the loan terms closely — interest-only periods inflate cash-on-cash temporarily, and that return typically drops once amortization kicks in.
• A high cash-on-cash number paired with a short lease term or a weaker tenant credit is a trade-off, not a free lunch. Ask what risk is being taken on to produce that number.

How to use it to your advantage

Use cash-on-cash to compare deals on equal footing, not just cap rate to cap rate. Two properties with the same cap rate can produce very different returns once you factor in how each one is financed.

Run the number at more than one loan structure before you commit. Shop your financing the way you shop the property — the spread between your interest rate and the cap rate is doing real work on your return, and it's often the easiest lever you have to pull.

And don't evaluate it in isolation. Cash-on-cash tells you about annual income, not about appreciation, principal paydown, or what happens at exit. A full picture needs all three.

Best case, worst case

Best case:

• Cap rate comfortably exceeds your interest rate, so leverage boosts your annual return
• Rent escalations increase cash flow over the hold while the loan payment stays flat
• Strong tenant credit and lease term support a stable, predictable number year over year

Worst case:

• Interest rate exceeds the cap rate, so leverage drags the return below what an all-cash buyer would earn
• Interest-only period ends, amortization starts, and cash-on-cash drops right when you got comfortable with the old number
• Unbudgeted capital needs or a lease disruption eat into the cash flow the return was built on
