What is a good cash-on-cash return?
A practical framework for judging cash-on-cash return, including leverage, risk, cash invested, market context, and why a high CoC can be a warning sign.

The short answer
There is no universal good cash-on-cash return.
A cash-on-cash return is a first-year, pre-tax cash flow measure divided by the cash invested. Whether it is “good” depends on what you are comparing it with and what risk you are accepting to get it.
Many US investors screen for a high single-digit cash-on-cash return on stabilized rentals. A range of roughly 6% to 10% is common in conversation. But that is a convention, not a standard, and it can be misleading in either direction.
A 6% return on a stable property with conservative financing may be better than a 12% return built on optimistic rent, understated expenses, and a short-term loan. The number is a starting point, not a verdict.
What the number actually measures
Cash-on-cash return is:
Annual pre-tax cash flow ÷ cash invested × 100
Annual cash flow is net operating income minus annual debt service. Cash invested is the cash required to close and stabilize the deal: down payment, closing costs, immediate rehab, lender fees, and other upfront cash.
That means the result is sensitive to three things:
- The operating assumptions behind NOI
- The loan terms behind debt service
- The cash-invested convention behind the denominator
Change any of them and the cash-on-cash return changes, even if the property is exactly the same.
For an all-cash purchase, there is no debt service, so cash flow equals NOI. The cash-on-cash return becomes the all-in cash yield on the property. It should be compared with the cap rate and with other low-leverage alternatives, not with a leveraged return from a different deal.
A context framework, not a rule
The ranges below are illustrative. They are a way to start a conversation, not a scoring system. Markets, property types, financing costs, and investor goals vary too much for a single threshold to be meaningful.
| Cash-on-cash range | What it often suggests | What to check |
|---|---|---|
| Negative | Current income does not cover operating costs and debt service | How will the shortfall be funded? Is there a credible path to positive cash flow? |
| 0% to 3% | Thin cash return; the case may depend on appreciation, principal paydown, or tax benefits | Are reserves funded? What happens after a vacancy or tax increase? |
| 4% to 6% | Modest leveraged cash return | Is the property in a low-risk market? Is the loan constant below the cap rate? |
| 6% to 10% | A common screening range for stabilized rentals | Are the rent, vacancy, and expense assumptions realistic? |
| Above 10% | Strong on paper; often higher leverage, higher risk, or optimistic assumptions | What is driving the result? Is the downside case still acceptable? |
The table is deliberately broad. A 5% return in a supply-constrained market with low leverage may be a deliberate core investment. A 15% return in a declining market with a balloon loan may be a speculation. The label should match the risk.
Compare it with the right benchmarks
A cash-on-cash return does not exist in a vacuum. Put it next to other numbers that answer different questions.
Cap rate is the property’s unleveraged operating yield. It tells you whether the property itself is priced to produce income before financing. If the cap rate is below the loan constant, leverage is likely reducing the cash yield.
Loan constant is annual debt service divided by the loan amount. It captures the full cost of the mortgage, including principal. Comparing the cap rate with the loan constant gives you the leverage spread.
Cash flow per unit is a budget check. A property can show a respectable cash-on-cash return on a small down payment while producing very little cash per unit. That matters when a vacancy or repair arrives.
Reserves are not optional. A deal that looks good before reserves may look thin after you set aside money for turnover, repairs, and capital replacements. Decide whether reserves are inside NOI or held outside it, and be consistent.
Alternative returns matter. If a low-risk investment offers a comparable yield, a leveraged rental with tenant, maintenance, and financing risk should offer a premium. The size of that premium is a judgment call, but it should be explicit.
The leverage test
Leverage can make a cash-on-cash return look strong. It can also make a deal fragile.
When the property’s cap rate is above the loan constant, the leverage spread is positive. The debt is accretive to the property-level cash yield. When the loan constant is above the cap rate, the spread is negative. The debt is reducing the cash yield, even if the cash-on-cash return is still positive.
A high cash-on-cash return from a low down payment is not free. It usually means:
- A larger loan payment relative to the property’s income
- Less equity cushion if values fall
- More sensitivity to interest rates at refinance
- A tighter debt-service coverage ratio for the lender
- Less room for vacancy, repairs, or a tax reassessment
The right question is not “how high is the return?” It is “what happens to this return if the loan resets, the rent falls, or the property sits vacant for two months?”
Why a high number can be a warning sign
A cash-on-cash return is only as good as its inputs. Some of the common ways a high number appears:
Optimistic rent. The pro forma uses market rent that the property has never achieved, or ignores concessions and turnover costs.
Low vacancy. The model assumes near-full occupancy in a market with seasonal demand, long lease-up, or a large new supply pipeline.
Understated expenses. Taxes are based on the seller’s assessed value, insurance is a placeholder, maintenance is a percentage that does not match the age of the property, and capital items are excluded.
Deferred maintenance. The property looks cheap because it needs a roof, HVAC, plumbing, or a full make-ready. The rehab cost belongs in cash invested and in the cash flow plan.
Aggressive financing. A short-term, interest-only, or low-doc loan can produce a higher cash-on-cash return in year one and a much larger risk at maturity.
Tenant concentration. A multi-unit property with one tenant paying most of the rent is not diversified just because it has several doors.
Market risk. A high return in a declining market may be compensation for risk, not a bargain. Verify the demand drivers, supply pipeline, and exit assumptions.
None of these means a high cash-on-cash return is bad. It means the number needs a story that survives the downside case.
Stress-test before you decide
A good cash-on-cash return should survive a reasonable range of outcomes. Try these tests:
- Increase vacancy by 2 to 3 percentage points.
- Reduce rent by 5% and hold expenses constant.
- Increase property taxes by 10% to 20% after reassessment.
- Increase insurance by 10% to 25% in a stressed market.
- Add a capital reserve if your base case excluded one.
- Raise the interest rate by 1 percentage point at refinance.
- Model a 30-day vacancy between tenants plus a make-ready cost.
- Check the result with a 10% lower purchase price and a 10% higher purchase price.
If the deal only works in the base case, the base case is doing too much work.
Set a target that matches your strategy
A target cash-on-cash return should come from your own requirements, not from a generic list.
A core, low-leverage investor may accept a lower cash return in exchange for stability, appreciation, and a lower loan constant. A value-add investor may accept a lower year-one return because the plan includes renovation and rent growth. A high-leverage investor may target a higher current return to compensate for refinance and vacancy risk.
Write down the target before you run the deal. Then ask whether the deal clears it with conservative inputs. If the answer depends on the best-case rent and the lowest plausible vacancy, it is not a comfortable margin of safety.
How the cash-on-cash calculator helps
The cash-on-cash return calculator shows the all-in cash invested breakdown, the down-payment-only return, the cap rate, the loan constant, the leverage spread, the break-even interest rate, financing scenarios, and a cash-on-cash projection.
Use it to compare the same property under different down payments and loan terms. Then change the operating assumptions and see which output moves most. The goal is not to find a single “good” number. It is to understand which assumptions the deal depends on.
For the underlying math, read the cash-on-cash return formula. For the property-level comparison, read cap rate vs. cash-on-cash return. For the monthly budget view, use the rental cash flow calculator.
Bottom line
A good cash-on-cash return is high enough to compensate you for the risk you are taking, robust enough to survive a downside case, and based on conservative inputs.
There is no universal threshold. A high single-digit return is a common screening range, but the number only means something when it is paired with the cap rate, the loan constant, realistic expenses, funded reserves, and a clear financing plan.
Use cash-on-cash return as one lens on the deal. Then check the assumptions behind it before you call it good.
Common questions
Frequently asked questions
What is a good cash-on-cash return on a rental property?
There is no universal answer. A common screening range for stabilized, conventionally financed rentals is roughly 6% to 10%, but the right target depends on the market, property type, condition, financing, and the investor's required return. A higher number is not automatically better if it comes from optimistic assumptions or higher risk.
Is a 10% cash-on-cash return good?
A 10% cash-on-cash return can be attractive, but only if the cash flow, vacancy, expenses, and reserves are realistic. A 10% return on a property with deferred maintenance, a high vacancy market, or a short-term loan may carry more risk than a 7% return on a stable property with conservative financing.
Should cash-on-cash return be higher than cap rate?
It can be higher when the loan constant is below the property's cap rate, which is positive leverage. It can be lower when the loan constant is above the cap rate, closing costs are high, or the deal has negative leverage. Neither result is automatically good or bad; the spread explains the direction.
What is a good cash-on-cash return for an all-cash purchase?
For an all-cash purchase, cash-on-cash return is essentially the all-in cash yield on the property. It should be compared with the cap rate and with other low-leverage alternatives, not with a leveraged cash-on-cash return. The absence of debt reduces financial risk but also removes the possibility of positive leverage.
How much vacancy should I assume when judging cash-on-cash return?
Use a vacancy assumption that reflects the local market and the property type, not a best-case number. Stress-test a few percentage points above your base case. A deal that only works at 3% vacancy in a market with seasonal demand or long turnover times is fragile.
Does a high cash-on-cash return mean a deal is low risk?
No. Cash-on-cash return is not risk-adjusted. It can be high because the down payment is low, the property is in a high-risk segment, the rent assumption is aggressive, or the expense estimate is incomplete. Check the inputs and the downside case before treating the number as a green light.
