I don’t want to appear rude, but don’t you think you might stand a better chance if you told the potential purchasers up front about the quarry? If I was buying and had to pay money to find out there was a potential quarry, I wouldn’t go any further out of principle. If on the other hand they already know, it isn’t a problem!!
When I bought my first house, a new quarry was planned for the area and prices rocketed. I managed to sell my house with no problems, although circumstances are probably a little different.
I take it you aren’t having to get a HIP, otherwise the information would be provided in the pack.
I do hope you sell your house and realise your dream, but just thought I should speak as a third party.
