Which source provides general data about the physical characteristics of a market area?

The source that provides general data about the physical characteristics of a market area is area maps. Area maps typically illustrate various physical attributes such as zoning, land use, topography, and infrastructure, which are essential for understanding the characteristics of a specific market area. By examining area maps, appraisers, real estate professionals, and researchers can glean insights into how these physical features influence property values and market trends.

In contrast, financial statements focus on the monetary aspects of properties and businesses rather than their physical characteristics. The Register of Deeds primarily deals with property ownership records and legal documentation, which, while important in real estate transactions, do not provide a broader view of the physical traits of an area. Tax assessor records are mainly concerned with property valuations and tax information, which again do not offer the general geographic context that area maps do. Therefore, the utility of area maps in providing a comprehensive overview of a market area's physical characteristics makes it the correct choice in this context.
