Tax Liens or assignment

[Stephen Mallen]

I have a property next door and the taxes are owed, it will go for auction February the taxes are only around $300 for the past two years.  The property is only worth  around $6000. I know the past owners are not going to pay. The property is in Arizona so its 3 year redemption period. Should I wait tell auction and buy or pay the back tax and hold the lien for 3 years. Also is there anyway to receive a insured title faster then the 3 year wait and or is it faster to buy at auction to receive title faster?
