Transmission Lines Increase and Decrease Property Values: The Appraisal Journal

September 27, 2016 08:00 AM

CHICAGO (Sept. 27, 2016) – Property values are affected in both positive and negative ways by their proximity to transmission lines, according to an article published this week in The Appraisal Journal.

The Appraisal Journal is the quarterly technical and academic publication of the Appraisal Institute, the nation’s largest professional association of real estate appraisers. The materials presented in the publication represent the opinions and views of the authors and not necessarily those of the Appraisal Institute.

“Property Value Impacts from Transmission Lines, Subtransmission Lines, and Substations,” by Ted Tatos, Mark Glick, Ph.D., JD, and Troy A. Lunt, MAI, analyzes the effects of various types of transmission lines on neighboring property values. The study found some homes are positively impacted by transmission lines that have greenways beneath. Others are impacted negatively, depending on the type of transmission line and distance to the transmission lines or substation. The study – which examines 125,000 home sales over a 14-year period – is distinctive because of its size.

Read “Property Value Impacts from Transmission Lines, Subtransmission Lines, and Substations” in the Summer issue of The Appraisal Journal.

Also in The Appraisal Journal’s Summer 2016 issue:

“Capital Layer Evaluations: Hotels and More,” by Tom Troll, presents a potential approach for the valuation of hotels, nursing homes and other complex properties that present challenges in analyzing and separating values between tangible and intangible components.

“An Empirical Study of the Impacts of an Express Rail Link on Property Prices – Hong Kong Evidence,” by K. F. Man, Ph.D., and Peter P. Y. Mok, examines the impact underground high-speed railways have on nearby property values. The study finds that although underground railways limit future property development, they positively affect sale prices.
