Rental cash flow is not rent minus the mortgage. Start with collected rent, subtract vacancy and operating expenses to calculate net operating income, then subtract debt service. Property management should still be modeled when you plan to self-manage because your time has value and the property may eventually need professional management.
A property that only cash-flows when vacancy, repairs and future replacements are set to zero is not conservatively underwritten. Stress the rent downward and expenses upward before deciding what to offer.
OneDEAL includes capital reserves in its modeled operating expenses. A lender may calculate NOI differently. See the cash-flow and cash-on-cash worked example →
Test a rental scenario →GUIDE 02
Debt-service coverage ratio compares a property's net operating income with its required debt payments. A DSCR of 1.30 means the modeled operating income is 1.30 times the modeled debt service. It describes debt coverage; it does not prove that the price, condition, cash invested or return is attractive.
Use DSCR alongside monthly cash flow, cash-on-cash return, break-even occupancy, liquidity after closing and upcoming capital work. Also confirm how the actual lender defines income and expenses. A calculator estimate is not a loan approval or lender quote.
Compare NOI-based DSCR with rent-to-PITIA methods →
GUIDE 03
A BRRRR refinance is commonly estimated by multiplying after-repair value by the lender's maximum loan-to-value ratio. That is only one limit. The stabilized property's income may support a smaller loan under the lender's DSCR requirement.
The smaller number determines realistic proceeds. From those proceeds, subtract the debt being paid off and refinance costs to estimate cash returned. If the deal leaves money invested, evaluate the remaining equity, monthly cash flow and return on the cash still trapped in the property instead of calling the project a failure automatically.
