What the Calculator Measures

Net Operating Income (NOI)

Estimated rental income after vacancy and operating expenses, but before mortgage payments and income taxes.

Cap Rate

NOI divided by the purchase price. It is one way to compare a property's operating return independent of financing.

Cash-on-Cash Return

Estimated annual cash flow divided by the initial cash invested, including down payment, closing costs, and initial repairs.

DSCR

Debt service coverage ratio compares NOI with annual mortgage debt service and can help evaluate how comfortably the property's operations cover the loan payment.

Vacancy & Reserves

Using realistic vacancy, maintenance, and capital reserves helps prevent an investment from looking stronger on paper than it may perform in practice.

Monthly Cash Flow

The estimated amount remaining after vacancy, operating expenses, reserves, management, and mortgage principal and interest.

Need Better Rent Assumptions?

A rental-property calculator is only as useful as the numbers entered into it. If you are evaluating a North Shore property, request a complimentary rent analysis to get a more informed rental estimate before relying on projected cash flow.
