NOI: does the property cover its operating costs?
Use modeled NOI to inspect income after vacancy and operating costs, before debt service. Positive NOI is not the cash left after paying the loan.
Transparent underwriting
How the calculator turns property assumptions into cash flow, debt coverage, returns, and strategy comparisons.
These numbers answer different questions. Start with the property’s operations, then its debt payments, then the cash you have invested. A favorable percentage alone does not make a deal affordable or a forecast reliable.
Use modeled NOI to inspect income after vacancy and operating costs, before debt service. Positive NOI is not the cash left after paying the loan.
Use monthly cash flow to inspect the modeled operating surplus or shortfall after required debt payments. Check whether reserves are included; repairs and vacancies do not arrive evenly each month.
Use cap rate to relate annual modeled NOI to the strategy’s property basis, not to your down payment. It does not tell you your cash return after the loan payments.
Compare annual pre-tax cash flow with modeled cash invested. Inspect that cash amount, not just the down payment: closing costs and project cash can also matter. A larger down payment changes both debt service and invested cash, so do not assume it improves the percentage.
DealCooker’s NOI may include reserves and financing-dependent fixed costs such as PMI. Its cap rate is therefore not necessarily a conventional unlevered cap rate. Most acquisition views use purchase price as the basis; BRRRR uses ARV. Compare like definitions and periods, not just labels.
Follow the rental worked example or inspect the BRRRR example. Replace illustrative inputs with verified property facts before relying on a result.

Short version
DealCooker is a pre-tax real estate underwriting model. It connects acquisition cash, financing, strategy-specific income and expenses, reserves, debt service, refinance events, and sale assumptions into one traceable projection.
Modeled property income after vacancy and operating costs, before debt service. Depending on the strategy, DealCooker’s modeled NOI may include reserves and fixed costs such as PMI, so it may differ from lender or accounting NOI.
Modeled monthly NOI minus required monthly debt service. DealCooker may also show a view before selected reserves for transparency.
Annual modeled NOI divided by the basis used for that strategy. Most acquisition views use purchase price; BRRRR uses ARV. Because modeled NOI can include financing-dependent fixed costs, treat this as a DealCooker metric—not a universal unlevered cap rate or appraisal.
Modeled NOI divided by modeled debt service. A ratio above 1 means NOI exceeds debt service, but lender definitions and thresholds vary.
Annual pre-tax cash flow divided by modeled cash invested. It is sensitive to leverage and does not replace a full hold-period analysis.
ROI measures total modeled gain relative to invested cash. IRR annualizes the timing of initial cash, operations, refinance events, additional contributions, and exit proceeds.
Airbnb host fees apply to room revenue plus charged cleaning fees. The long-term rental placement-fee input is informational and excluded from returns; budget actual leasing costs separately. A HELOC amount is the actual draw, not a credit limit. BRRRR cash left after refinance is different from the money needed at the start.

Model boundaries
No. It projects user-entered assumptions. It does not guarantee rent, occupancy, financing, appraisal, costs, refinance terms, sale value, or returns.
No. Results are pre-tax estimates. Tax treatment varies by property, activity, ownership, jurisdiction, and taxpayer; use a qualified tax professional.
No. DealCooker is not an appraisal, broker price opinion, credit decision, loan quote, or commitment to lend.
Confirm the rent roll, leases, market rents, expenses, insurance, taxes, title, zoning, permits, inspections, contractor bids, financing, and exit assumptions independently.
