Frequently Asked Questions

Real estate investors typically aim for at least $200 to $300+ in net cash flow per month per unit (door) after setting aside all reserves.

It takes the purchase price, the capital invested, the gross annual income, the annual operating expenses, and the annual debt payments. From those it derives the cash flow figures without needing a month-by-month expense breakdown.

Net operating income is the gross annual income less the annual operating expenses. Subtracting the annual debt payments from that gives the annual net cash flow, and dividing by twelve gives the monthly figure the tool displays.

Both the purchase price and the gross annual income have to be above zero. If either is left at zero the calculator halts with the message 'Please enter valid revenue and purchase details.'

No. It works from annual totals: one gross income figure, one operating-expense figure, and one debt figure. Combine your taxes, insurance, maintenance, and management into those annual amounts before entering them.
