I bet the estate agent said, don't bother tidying up as the market is so mad at the moment, anything will sell!
Last time we bought, the market was like this and we were shown 2 houses much like this where the old people lived in about half the house and hoarded in the other half so we could only see half the rooms. The estate agent wasn't bothered that at all and basically said if we didn't buy it, somebody would.
