Tax Sale Prep

[Nghi Le]

I'm planning on attending my first tax deed foreclosure sale/auction in a couple of months in Seattle, WA (King County).  Just wanted to see if anyone has been to this specific auction before, and what was your experience like?

Some general questions about tax sales:
I'm considering driving by all of the properties to check them out (after I narrow down the list online).  Would you guys recommend that, or is that a waste of time?  Do the majority of them not make it to the auction?  If so, is it because investors are reaching out to them before the auction (and is that legal)?
