Reading the results
The top number is monthly cash flow after the mortgage, with cap rate, cash-on-cash and net operating income.
Quick checks show debt service coverage, gross rent multiplier, the 1% rule and the break-even rent. Where it goes shows equity, total cash flow and total return in years 5 and 10.
Estimates to check
Figures are before income taxes and depreciation. Verify rents with active comps and expenses with actual bills. Growth rates are assumptions.
