What is NOI in Real Estate?

Understanding this profitability metric can help you make smarter allocation decisions.

Accredited investors who transition from investing in publicly traded stocks to private real estate must contend with a new lexicon of financial metrics. 

Although investing in private real estate investment funds—like DLP Capital-sponsored funds—means you aren’t managing day-to-day property operations, understanding the math underlying your fund’s portfolio can help you make more intelligent allocation decisions.

One of the most important metrics that allows investors to understand the performance of the assets in a real estate fund is Net Operating Income (NOI).

What is Net Operating Income (NOI)?

Net Operating Income (NOI) is a calculation that describes the ongoing profitability of an income-generating real estate asset. In simple terms, NOI is what’s left over when you take the total revenue generated by a property and subtract all operating expenses.1

Conceptually, a property’s NOI measures its operational efficiency. While NOI removes operating expenses from total income, it excludes major capital expenditure (CapEx) items, such as the cost of replacing roofs, HVAC systems, or parking lots.1

It also excludes debt service and financing expenses (mortgage payments), depreciation, and income taxes (but not property taxes). This isolation makes NOI a measure of how effectively a property is being managed at the ground level.

How is NOI calculated?

The formula for NOI is straightforward:
Net Operating Income = Total Operating Income – Operating Expenses

Here is a breakdown of those two main components:

Total operating income

This is the total potential income from rent, assuming the property is fully occupied, minus losses from vacancies and credit defaults. It also includes ancillary revenue streams, like parking fees, laundry facilities, or pet rent.

Operating expenses

These are routine, day-to-day costs required to keep the property running and generating revenue. Common examples include, payroll, property management fees, routine maintenance, insurance, property taxes, and utilities.

Why NOI matters to private real estate investors

NOI matters for accredited investors, even those investing through a fund. That’s because the aggregate NOI of the properties within your fund impacts your bottom line in three ways:

It drives property valuations

In commercial real estate, a property's value is deeply tied to the income it generates. At a constant cap rate, a higher NOI leads directly to a higher property valuation. If the aggregate NOI generated by a fund rises, per-unit Net Asset Value (NAV) could also rise.

It influences yield

The distributions you receive from a private real estate fund are ultimately derived from the underlying NOI of its assets. A stable, growing NOI across a portfolio of attainable workforce housing translates to reliable cash flow for the fund’s limited partners, assuming below the line expenses remain stable. 

FAQs

A property’s valuation is based on its NOI divided by its cap rate. For example, a property generating $1 million in NOI trading at a 7% cap rate is valued at roughly $14.3 million.

NOI is used in real estate to measure a property’s profitability. This metric allows investors to compare and value properties and assists lenders in underwriting mortgages.

A higher Net Operating Income (NOI) is better. It means the property generates more income relative to its operating expenses and generally results in a higher valuation.
