I don't really see it that way - how much do you want to know about it? if you are buying a Victorian house, for example, it's safe to assume that most of it is shot to f***.
You could spend a lot of time, effort and money trying to quantify exactly how bad it is, but to what end?
Isn't just the feature of a crappy system where you offer a price for something that you don't know the condition of beyond a cursory glance
