What the calculation measures
This combines operating and financing metrics so you can see why a property can have a reasonable cap rate but weak leveraged cash flow.
How to interpret the result
Run rent, vacancy and repair-cost scenarios rather than relying on the listing projection.
Run scenarios instead of one answer
Change the most uncertain input and compare outcomes. A calculator is most useful when it shows sensitivity, not when one estimate is treated as a guarantee.
Limits and assumptions
Use detailed tax, insurance, capital expenditure and financing data before making an investment decision.
