This document provides an overview of intangible assets and how they relate to real estate valuation. It discusses how intangible assets are identified and the legal tests used. There are typically two circumstances where assessors encounter intangible value: 1) when a property sells and intangible assets are included in the price, along with real and personal property, and 2) when income from a business is used to value real estate in an income approach for property types like hotels and nursing homes. The document then examines the accounting, business, and real estate purposes for allocating intangible assets. Finally, it reviews methods for estimating intangible value, including the cost, market, and income approaches.
