From rent to cash flow: the NOI waterfall

Gross rent shrinks at every step: vacancy, operating expenses, the mortgage and reserves. NOI is the property's income before financing; cash flow is what you keep.

Formula

Effective gross income = Gross scheduled income − VacancyNOI = Effective gross income − Operating expensesCash flow = NOI − Debt service − Capital-expenditure reserve

Assumptions

  • 30-year fixed loan, no points; one unit with no other income, HOA or utilities.
  • Vacancy is taken off gross rent; management, maintenance and the capital-expenditure reserve are a share of collected rent.
  • The capital-expenditure reserve sits below NOI: it is cash set aside, not an operating expense.
  • Income taxes, depreciation and appreciation are left out.
