Tax Lien Property in AZ

[Bret W.]

Not sure if this is the right category... hopefully it is.

There is land behind my house that is being used for storage. The land has no access to the street. It appears at some time the property owner of the house in the front of the lot installed a fence and sold the back portion. The only access if from the alley. The owner is storing a boat and a pull-behind trailer on it. I have never seen or met the owner. I did some research to reach out and offer to buy the land. I would love to build a garage/workshop on it. After a little digging, I noticed the taxes have not been paid since 2006 and a tax lien is available for last year, all other years already have a lien placed on it. The owed taxes plus interest is +-15k. 

What are my options for purchasing this land? What do you recommend.
