The definition of __________ appraisal includes the phrase "One in which the property to be appraised, the form of ownership, or the market conditions are atypical."

The term "complex one-to-four family residential property" specifically refers to properties that may have unusual features, ownership situations, or market conditions that necessitate a more in-depth appraisal process. This definition captures scenarios where the typical appraisal methods might not be sufficient due to the unique attributes of the property in question.

In this context, "atypical" suggests that the property or its circumstances deviate from standard, easily comparable properties. This complexity can arise from factors such as unique architectural styles, mixed-use spaces, or specific zoning regulations that differ from the norm. As a result, appraisers must apply a more nuanced approach to evaluate the property's worth, considering not just the physical structure but also its market position and ownership intricacies.

Other types of appraisal, like standard residential properties or government-owned properties, typically deal with more traditional and standardized scenarios, which is why they do not fit the description provided. Commercial property appraisals, while potentially complex, cover a broader category that encompasses various types of income-generating properties rather than focusing specifically on the nuanced complexities of one-to-four family units.
