Marketing
It isn't though, is it? or at least it's not good marketing.
There's a house not far from us which was for sale for ages, and has a similar blindingly obvious 'issue' next door which was cut out of the estate agent's photos. The neighbour adjacent to it said loads of people came to view before turning straight round and driving away again.
If the wind turbines are that obvious when visiting the property, nobody who hates them is going to buy it, so why not show them in the photos?
