Net Operating Income (NOI)

A property's effective rental and other income after subtracting operating expenses, but before debt service, income taxes, capital expenditures, and depreciation. It is the core measure used to compare property performance and to value income-producing real estate.

Related: Capitalization Rate, Operating Expense Ratio, Cash-on-Cash Return
Capitalization Rate (Cap Rate)

The ratio of a property's net operating income to its purchase price or market value, expressed as a percentage. It converts a single year of income into an indicative value and lets investors compare risk and return across properties.

Related: Net Operating Income (NOI), Direct Capitalization, Gross Income Multiplier
Direct Capitalization

A valuation method that divides a stabilized year of net operating income by a market-derived capitalization rate to estimate value. It assumes a steady income stream and is most reliable for stable, well-leased properties.

Related: Capitalization Rate (Cap Rate), Net Operating Income (NOI), Discounted Cash Flow (DCF)
Discounted Cash Flow (DCF)

A valuation technique that projects annual cash flows over a holding period, discounts them to present value at a required return, and adds the discounted proceeds from sale. It captures timing, growth, and reversion value that a single-year multiple ignores.

Related: Direct Capitalization, Internal Rate of Return (IRR), Net Present Value (NPV)
Internal Rate of Return (IRR)

The discount rate at which a project's net present value equals zero. It expresses the annualized compound return earned on invested capital, and a project is generally acceptable when its IRR exceeds the investor's required return.

Related: Net Present Value (NPV), Discounted Cash Flow (DCF), Equity Multiple
Net Present Value (NPV)

The dollar amount by which the present value of expected future cash flows exceeds or falls short of the initial investment. A positive NPV suggests the investment earns more than the discount rate applied.

Related: Internal Rate of Return (IRR), Discounted Cash Flow (DCF), Discount Rate
Equity Multiple

Total cash distributions received by an equity investor, including sale proceeds, divided by the equity originally invested. It measures overall profit without regard to timing, so it is usually read alongside a return measure such as IRR.

Related: Internal Rate of Return (IRR), Cash-on-Cash Return
Cash-on-Cash Return

Annual pre-tax cash flow after debt service divided by the equity invested. It shows the current income yield on an investor's own money and is often used for leveraged acquisitions and value-add comparisons.

Related: Net Operating Income (NOI), Debt Service Coverage Ratio (DSCR), Equity Multiple
Operating Expense Ratio

Total operating expenses divided by effective gross income. A lower ratio generally signals efficient operations or a lease structure that shifts costs to tenants, and the figure is compared against similar properties.

Related: Net Operating Income (NOI), Gross Income Multiplier
Gross Income Multiplier

Sale price or value divided by gross annual income. It is a quick screening ratio that ignores expense differences, so it is most useful when comparing properties with similar operating profiles and lease structures.

Related: Capitalization Rate (Cap Rate), Operating Expense Ratio
Effective Gross Income

Potential gross income plus other income, reduced by vacancy and collection losses. It represents the income a property is realistically expected to collect and is the starting point for the operating expense analysis.

Capital Expenditure Reserve

A budgeted annual allowance set aside for replacement of short-lived building components such as roofs, HVAC systems, and parking surfaces. Underwriters deduct it from income to reflect the true cost of sustaining a property.

Related: Net Operating Income (NOI), Deferred Maintenance
Deferred Maintenance

Necessary repairs or replacements that have been postponed, creating a backlog of physical needs. It depresses value, raises future capital requirements, and is a frequent source of post-closing disputes in acquisitions.

Related: Capital Expenditure Reserve, Physical Life Cycle
Physical Life Cycle

The sequence of phases a building passes through, from planning and construction through stabilization, aging, and eventual renovation or demolition. It frames capital planning and the timing of major reinvestment.

Related: Deferred Maintenance, Capital Expenditure Reserve
Highest and Best Use

The reasonably probable, legally permitted, physically possible, financially feasible use of a site that produces the greatest value. It anchors appraisals and redevelopment decisions because value is measured under that use.

Related: Direct Capitalization, Absorption Rate
Absorption Rate

The pace at which available space in a market is leased or sold over a period, usually stated in square feet per month or year. It informs rent growth assumptions, lease-up schedules, and new construction timing.

Related: Vacancy Rate, Highest and Best Use
Vacancy Rate

The share of rentable space that is unoccupied and not generating rent, often expressed as a percentage of total inventory. It signals market balance and drives concessions, renewal strategy, and revenue forecasting.

Triple Net Lease

A lease in which the tenant pays base rent plus its share of property taxes, insurance, and common area maintenance. It shifts operating cost variability to tenants and makes net income more predictable for owners.

Related: Common Area Maintenance (CAM) Reconciliation, Gross Lease, Lease Abstract
Gross Lease

A lease in which the landlord pays most or all operating expenses out of the rent collected. The owner bears cost volatility, so gross leases require careful expense budgeting and rent escalation planning.

Related: Triple Net Lease, Common Area Maintenance (CAM) Reconciliation
Common Area Maintenance (CAM) Reconciliation

The annual process of comparing estimated tenant reimbursements for shared expenses with actual costs, then billing or crediting the difference. Accurate reconciliations protect landlord income and tenant relations.

Related: Triple Net Lease, Escalation Clause

A lease provision that increases rent on a schedule or by an index such as CPI. It preserves the real value of rental income over the term and must be modeled carefully in cash flow projections.

Related: Loan-to-Value Ratio (LTV), Cash-on-Cash Return, Net Operating Income (NOI)
Loan-to-Value Ratio (LTV)

The loan amount divided by the property's appraised value or purchase price. A higher ratio means more leverage and greater risk to the lender, so it is paired with coverage tests in underwriting.
