In a more typical market a house under not close to powerlines or backing to a busy street will discount 5 to 10%. A house this close would not but might take a few more buyers to see it to get a buyer that isn’t bothered looking at them down the street.
A lot that big can easily command a 10 to 20% premium in any market. After all most of what you are buying here is land value and more land is more value.
Zillow and Redfin valuations cannot account for things like powerlines with their algorithms. Perhaps someday they will but right now the answer is they dont. The only way they could is a house one or two away sold in the same situation in which the valuation of the subject house would impacted by that comp.
