Definition
In real estate, capitalization (or "capping") refers to the process of converting a property's annual income stream into a present value (property price) using a capitalization rate. It is the fundamental income approach to property valuation used by appraisers, lenders, and institutional investors for any income-producing real estate. The process is simple: divide NOI by the market cap rate to derive value.
The Capitalization (in Real Estate) Formula
Variables explained:
NOI is annual net operating income (gross rent minus vacancy minus operating expenses). Cap Rate is the prevailing market capitalization rate for comparable properties — determined by analyzing recent sales. The result is the implied value of the property at that market cap rate.
Capitalization (in Real Estate) Example with Real Numbers
A 6-unit apartment building generates an NOI of $54,000/year. Comparable multifamily properties in the area sell at a 6.5% cap rate. Capitalized Value = $54,000 / 0.065 = $830,769. If you can raise rents by $100/unit/month ($7,200/year additional income), the new NOI = $61,200. New capitalized value = $61,200 / 0.065 = $941,538 — a $110,769 increase in property value from a $7,200 annual income improvement.
Why Capitalization (in Real Estate) Matters for Investors
Capitalization is how NOI growth translates into property appreciation for income-producing real estate. Unlike residential properties (priced by comps), commercial and multifamily properties are valued almost entirely by their income. This means investors can directly engineer property value increases by raising rents or cutting expenses — not by waiting for the market to rise. Understanding capitalization makes you a more sophisticated buyer and seller.

Frequently Asked Questions
How is property value calculated using capitalization?
Property Value = NOI ÷ Market Cap Rate. If the market trades at a 6% cap rate and your property generates $30,000 NOI, its implied value is $30,000 / 0.06 = $500,000. This is the standard commercial real estate valuation method.
How do cap rate changes affect capitalized value?
They move inversely. If market cap rates compress from 6% to 5% (rates fall), the same $30,000 NOI capitalizes to $600,000 instead of $500,000 — a 20% value increase. Cap rate compression is a major driver of multifamily appreciation in low-rate environments.
Is capitalization used for single-family rentals?
It's used as a cross-check, but single-family homes are primarily valued by comparable sales (comps), not income capitalization. The income approach is dominant for 5+ unit multifamily, commercial, and industrial properties.
What is the difference between capitalization and discounted cash flow?
Capitalization uses a single year of NOI divided by one cap rate — it assumes income is constant or growing at a stable rate. Discounted Cash Flow (DCF) models each year of income and a reversion value separately, accounting for varying income growth, rent bumps, and a projected sale price.
