What is the term for gross rentals minus operating expenses minus principal and interest payments?

The term for gross rentals minus operating expenses minus principal and interest payments is correctly defined as Free Cash Flow. This concept refers to the amount of cash generated by a property after all the operational costs and debt obligations have been accounted for. It reflects the true cash available for distribution to investors, creditors, or for reinvestment.

Net Income, while related, typically refers to the profit of an entity after all expenses, taxes, and costs, but it does not focus specifically on cash flow. Spendable Income, although it implies availability of cash, is not a standard term commonly used in real estate or finance to describe this calculation. Operating Profit generally refers to earnings before interest and taxes but does not account for principal payments on debt, making it an insufficient representation of cash availability in this context.

Therefore, Free Cash Flow captures the essence of the calculation by demonstrating the liquidity available from an investment property after necessary expenses and financing costs are deducted.
