Can't believe you're been told to ignore this issue or to wait and see what happens....sorry but anyone would think you're buying a £10 pair of shoes which may or may not be suiteable...but hey! that's a £10 pair of shoes we're talking about there, so who cares! This is your new house LOL

Add which, 'newish' estates ALWAYS attract a certain sort of person and you know the type i mean....keeps up with the Jones's, did slightly better to get on a new estate, doesn't want antything happening 'in my back yard'. You won't have to wait long (in my experience) for someone to start making trouble IF you really aren't allowed to park your van.
But then ultimatly, isn't this what you're paying your solicitor lots of money for....? He/she'll be the one who will get this ironed out for you once and for all.
