County property auction sales

[Pandu Chimata]

LA county property auction sales are coming up next month. I head property tax liens takes the first place over the other mortgage liens.  How do we figure that out ? Even if the property tax liens takes precedence, once the property tax lien is paid off, should the mortgage lender come back to get their dues ?

I want to make sure how does this works if we buy the property at property tax auction sale ?
