A relative found out recently that the lawyer who recorded a lien for them put his law office as the notification address, not their home address.  10 years later when the guy stopped paying, they found out from the records' office that the home foreclosed and they never received notice because it went to the lawyer's office, now non-existent, not their home. 

Property taxes are public record, so you can use previous years paid and estimate a slight increase.

@David Krulac  there ya go completely different than most states.. out here CA you buy the property at tax sale you get a deed in a few weeks or a month or so from the tax collector you record it.. its yours.. now there is a 1 year statue in CA for the owner to come back and say something was wrong with the sale.. but it is not a redemption they have to prove the county messed up the sale in some way.. the easiest way is to prove the county did not advertise the specified days.. we lost one that way.. but that was one in over a thousand my dad bought over the years.In Oregon for Sure the county commissioners actually have the power to reverse the sale.. but that's just getting it back from the state.. next time I see you I will tell you about one case that is fascinating here. but I don't want to describe it in a public forum and give the bad guys ammo if you know what I mean.
