I bicycle around this area a lot and have noticed there is a very strong correlation between the house and lot values and the proximity to the power lines. Whether they are or are not a health/environmental hazard, what counts is the market’s perception, and it is very negative.
Another factor that will hurt these values is that most of the houses were put up in the runup to the 2005/6 price peak. The builders went for square footage over lower density, and the neighborhood show it. No amount of architectural gyrations will disguise the fact that your big box is smack next to your neighbors big box, and your 3rd and 4th cars are clogging the available street parking.
The next trend will be downsizing to reasonably-sized houses, shedding some possessions, and heating and cooling a smaller abode. This trend was in evidence in the earlier 1990s correction.
