For those that did not have remedial works completed, it is true that a reduced asking price is quite common. However this is usually due to the sale usually being a cash only purchase as most banks won't lend against such properties.
That said if the property is in a sought after area, even with it being a cash only purchase I have never seen them go for 40-50% below market value.
It may be different depending on where you are, I merely share my personal experience with you.
