A tax lien is usually levied on a property especially when a homeowner comprises and fails to pay county or local taxes related to a property. The taxing body/authority in such a situation will move and put the given property on tax lien. Once the tax lien has been levied; the tax body will then issue a tax lien certificate which can be bought by an investor who can be selected by several methods. Random selection can be made from those who have submitted a bid and other methods which can be sued to pick on a potential investor does include premium method, bidding down on the interest and bidding down on the ownership (click here to read more on the selection methods).
