If I think that property would most probably have sold for $300k on that day and under those market conditions then that's what I'm going to say. 10 times out of 10. Risk management is the user's job, not mine. Predicting what they think might happen in the future is their job, not mine. Making judgements about how wise/foolish their borrowers are is their job, not mine. Deciding what their max LTV is their job, not mine.
And yes, it's very common for value conclusions from different approaches to value to be different from one another; sometimes very different.
