How to analyze a rental property
This page gives the complete order of operations for analyzing a residential rental, from gross rent through to the stress tests that separate durable deals from fragile ones.
Each metric answers a different question. Cap rate asks what the property yields unlevered. Cash-on-cash asks what your cash earns. Debt coverage asks whether it survives. You need all three.
- What this is
- The full analysis sequence for a residential rental.
- Who it is for
- New and experienced investors underwriting a purchase.
- The problem
- Investors often calculate one metric and stop, then discover the deal fails on a dimension they never measured.
- What happens next
- Work through the numbers, then have taxes, insurance, rents and condition verified for the specific address.
1. Gross scheduled income to effective income
Start with market rent for every unit, add any other income such as parking, storage or laundry, then subtract vacancy and credit loss.
The result is effective gross income, and it is the only income figure that belongs in the rest of the analysis.
2. Operating expenses to net operating income
Subtract taxes, insurance, utilities, maintenance, capital reserves, management, and administrative costs. Do not subtract the mortgage, depreciation or income tax — those are not operating expenses.
Effective income minus operating expenses is net operating income, the number that drives both cap rate and value.
3. Returns
Cap rate is net operating income divided by price, and it lets you compare properties independent of financing. Cash-on-cash is annual pre-tax cash flow divided by total cash invested, and it tells you what your own money earns.
Debt service coverage ratio is net operating income divided by annual debt service. Below 1.2 is where lenders get uncomfortable, and they are usually right.
4. Stress the deal
Re-run it with rent five percent lower, vacancy at two months, the interest rate one point higher, and a full roof replacement in year three. Deals that only work in the base case are not deals; they are bets.
Finally, confirm the exit: who buys this property from you, and at what cap rate, if you need to sell in a weaker market?
The steps, in order
- 1
Establish market rent
Use comparable units currently leasing, not the seller's stated rents.
- 2
Apply vacancy and credit loss
Five to eight percent in most markets, higher for turnover-heavy unit types.
- 3
List every operating expense
Taxes as reassessed, rental insurance, utilities, maintenance, reserves and management.
- 4
Calculate net operating income
Effective gross income minus operating expenses, excluding the mortgage.
- 5
Calculate returns
Cap rate, cash-on-cash return and debt service coverage ratio.
- 6
Stress test
Lower rent, longer vacancy, higher rate and one capital event.

What is a good cap rate?
It depends entirely on the market and property class. In strong metros four to six percent is common; in secondary markets seven to nine percent. The useful comparison is against other properties in the same market, not a national benchmark.
What is the difference between cap rate and cash-on-cash return?
Cap rate ignores financing and measures the property. Cash-on-cash includes your loan and measures your invested cash. Leverage can raise cash-on-cash well above cap rate — and it magnifies losses just as efficiently.
Should I include my own labor as an expense?
Yes, at market rates for management and maintenance. Otherwise you are comparing a property's return against alternatives that do not require your weekends.
How do I estimate expenses on a property I have not owned?
Use actual tax records, get an insurance quote for the address, request twelve months of utility bills, and apply market ratios for maintenance and reserves. Seller-provided expense sheets consistently understate maintenance.
What return should a rental produce?
Many investors look for eight percent or better cash-on-cash in year one, with total return including principal paydown and appreciation well above that. Set the threshold from your alternatives, not from convention.
How does depreciation affect the analysis?
Depreciation reduces taxable income without reducing cash, which improves after-tax return, but it is recaptured on sale. Analyze pre-tax first, then consider tax effects with your accountant.
