Which appraisal approach is most appropriate for valuing an income-producing property such as an apartment building?

The income approach (income capitalization) is the primary method for valuing income-producing real estate like apartment buildings, office buildings, or shopping centers. The appraiser estimates the property's net operating income (income after operating expenses but before debt service) and divides it by a capitalization rate to arrive at value (Value = NOI / Cap Rate). The sales comparison approach is most relevant for residential homes, and the cost approach is most useful for new, special-purpose, or unique properties where comparable sales are scarce. A competent appraisal often considers all three approaches and reconciles them, but the income approach carries the most weight for investment property.
