Cash Flow Sensitivity

Rent and the interest rate are often the two numbers that decide whether a rental pays for itself. This grid shows monthly cash flow for each combination, so you can see where the deal turns negative.

The figures shown are example values. Replace them with your own; rates, taxes and insurance vary by lender, property and municipality.

Other income moves with rent. Expenses that are a share of rent (maintenance) or of income (management) move with it too.
