I'm going to respectfully disagree. The HT wires will reduce the value of your home. And whether or not it is accurate that they do/don't affect one's health, it is important to realize that this is an emotional issue. You will not convince someone otherwise. Personally, I'm in the camp that says they do affect health and I've walked away from an otherwise perfect home for that reason. Some cultures may also regard it as bad luck/ bad energy. You will not convince them otherwise. Therefore, you already have a reduced buyer pool. If you are buying this home, understand that it may take longer than average for this home to sell.
Wishing you the best!
