In the last year or so two very big, very old trees were cut down in our circle. Both were unfortunately a risk that the property owners didn’t want to deal with (one an issue with possible falling limbs, the other was threatening a sewage line.)
While I understand that, the loss of both trees can have an impact on how the neighborhood is seen, and reduce property value.
Likewise, I think transformer statues are cool. If I lived on the street, I wouldn’t be surprised if it affected my property value, and potential buyers. I would be annoyed, though.
This is why people formed HOAs, and why people like them.
