Determine Closing cost (WA)

[John Dickerson]

When doing deal analysis how would one determine the possible closing cost?

I have seen that the 'average' persons pay 3 to 5 percent but this number can go as high a 7 percent.

What is the best method or judgment to use when trying to get this number to do my analysis?

Lastly does closing cost percentage change or vary from state to state? I'm out of Vancouver, WA.
