Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

  1. Bullet Reduced property value - They may not cause cancer, but high-voltage power lines are definitely ugly. Multiple studies of property values of homes within sight of big power lines shows a decreased value of the real estate of up to 10%, and averaging around half of that.

    There is even one advantage to living near high-voltage transmission lines: lightning protection. The support tower and upper level of wires act as a lightning rod to protect homes in a wide radius from a lightning strike.
    At The Villages, Florida, where we live, the developer put golf courses and a nature preserve under a high-voltage power line that runs diagonally across the community, with landscaping, lakes, and meandering paths. Homes facing the power lines sell at a premium, but that is not the case elsewhere.

    So, if you buy a home near a power line, it will not affect your health, but will likely impact your property value when you sell.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
