Net operating income (NOI) is the total revenue a property generates minus all operating expenses, excluding mortgage payments and income taxes.
NOI is one of the most important metrics in real estate investing because it shows how much income a property produces from operations alone. It is calculated by taking gross rental income, subtracting vacancy losses, and then subtracting operating expenses like property management, insurance, taxes, and maintenance. While NOI is most relevant to income-producing properties, understanding it helps any real estate owner evaluate the true cost of ownership.
GoForth, a luxury co-ownership company, focuses on personal-use luxury homes rather than income-producing rentals, so NOI is not the primary metric for its owners. However, GoForth provides detailed annual budgets that break down all operating expenses, giving the four co-owning families full visibility into the cost structure. This transparency allows owners to understand exactly where their money goes and how efficiently the property is being managed.
