Arizona Tax lien foreclosure/quit claim deed

[Karen D. Schiano]

I have sent Intents to Foreclose on several properties in Arizona.  Two owners simply want to give the land to me because it is remote off grid raw land worth little (but alot to my Christian art retreat expansion for the aesthetic quality of the land) that they don't want to pay off the tax liens on.  Can they simply sign (and notarize) a quit claim deed or do I have to go through the foreclosure process and file with the court?  I'm new to this so I don't know if this is acceptable to Navajo County and they don't do much self help.  I don't know what happens with the tax lien then, I don't know if the county has additional fees they will want paid off or it simply gets dismissed by the transfer of ownership and of course, me paying taxes forward.  Thanks for your help.
