How the calculation works
Understand the formula before relying on the result
Net operating income
Recurring operating expenses, including management calculated on collected income, are deducted before mortgage debt service.
Financing and cash flow
The mortgage is modeled with monthly principal-and-interest payments using the selected compounding convention. Annual cash flow equals NOI less annual debt service.
Return and break-even measures
Cap rate uses purchase price, DSCR compares NOI with debt service, and cash-on-cash return divides annual cash flow by down payment plus acquisition cash.
Interpret the result
Start with NOI
NOI measures property operations before financing. It should be supportable by leases, market rent, vacancy, and realistic expenses.
Cash flow depends on financing
Two identical properties can have different cash flow because loan amount, rate, amortization, and acquisition cash differ.
Coverage matters
A DSCR below 1.00x means modeled NOI does not fully cover annual mortgage payments.
Returns require stress testing
Vacancy, repairs, renewals, capital expenditures, and rate changes can materially change the result.
Common mistakes
- Using gross rent as if it were NOI.
- Leaving vacancy at zero because the unit is currently occupied.
- Ignoring management, repairs, utilities, condo fees, or capital work.
- Comparing cash flow without comparing cash invested.
- Assuming lender rental-income treatment matches actual property cash flow.
What lenders review
- Property type, location, condition, and marketability.
- Lease terms, rent roll, market rent, and vacancy history.
- Normalized operating expenses and lender-adjusted NOI.
- LTV, DSCR, borrower liquidity, credit, and experience.
- Appraisal, environmental, zoning, and property-specific due diligence where applicable.
Planning tips
- Use trailing actual expenses when available.
- Run a higher-vacancy and higher-rate scenario.
- Separate recurring repairs from major capital improvements.
- Compare the result with the NOI, DSCR, and investment-return calculators.
- Keep a liquidity reserve outside the acquisition budget.

Frequently asked questions
Questions about this calculation
What expenses are included in rental-property NOI?
Recurring property-level operating expenses are included. Mortgage payments, income tax, depreciation, and major capital improvements are generally excluded from NOI.
What is a good rental-property DSCR?
There is no universal threshold. Lender targets vary by property, borrower, market, lease quality, and transaction risk.
Why can a property have a good cap rate but weak cash flow?
Cap rate ignores financing. A high loan amount, high rate, short amortization, or large reserves can reduce cash flow even when NOI is strong.
Does this calculator show after-tax return?
No. It is a before-tax planning model and does not provide tax, depreciation, or capital-cost-allowance advice.
Can lenders use different rental income than this calculator?
Yes. Lenders may use lease rent, market rent, add-back methods, rental worksheets, vacancy assumptions, or property-specific underwriting adjustments.
