High tension towers can be a problem, most people just don't like them. Years ago I was one of three RE appraisers hired by Cal-Vet when I received a call about a home in Crockett CA. When I was asked to go appraise it, I immediately told my boss at Cal-Vet that we can't loan on that home.
He asked "why?" and I informed him that I knew that house and there are high tension towers all around it. The home is clearly in the fall distance of a tower or two.
He breathed a sigh of relief as he stated "I thought I trained you all better than that, but one of our other appraisers failed to mention it or show it in the photos, and we already made the loan and now we are getting it back." Wow, I couldn't believe it. Then he asked me to go ahead and appraise it so they could figure out what to sell it for.
A few years ago in Charlotte an FHA 203k loan was going from a Streamlined k to a Full 203k and they need a rush consultation. Most of them are rushes, by the way, lol. When I arrived I found a high tension tower adjacent to the house. Again, there was no photo in the appraisal, but the appraiser did mention in the addendum but only casually. If there is a high tension tower within the fall distance of the home, and this one was with twenty feet of a 100' tower, FHA doesn't make that loan guarantee.
I called in to let the lender know about the tower and they killed the deal right then. This can be a conventional loan but in any case the problem needs to be addressed in the reports in all cases.
Once discovered later on after the loan was made the lender would have to repurchase that loan. That is not a good situation.
