You're making yourself a hostage to fortune. No matter how cautious and considerate the WG is, and I'm sure many are, you can't legislate for punters who are real nutters, likely to put you in shit with your neighbours, possibly the local fuzz, the council and your freeholder (if applicable). One perfectly nice and considerate girl I knew in the Northeast, living and working in a suburban house that seemed ideally discreet, had one obsessed and vindictive (ex-)punter started putting notes on her neighbours' cars and on lamp posts outing her in the most vile language. She moved shortly afterwards.
