We're buying at the moment and offer was accepted a month ago around 95% of asking price. I'd agree that starting with 10% or even 15% is acceptable as market condition couldn't be worse right now and buyers are in a great position to bargain hardly. The property we're buying is in Zone 1 so it should qualify for your standard but again it really depends on what sort of price range you're looking at. For example > 1M market you may still face strong competition as richers are still around
