After redemption period on a tax lien what paperwork do they issue?

[Jocelyn Bernstein]

I have called several title companies and attorneys and none of them can lead me in the correct direction. After the 3 year period to redeem property, what am I to do as the tax payer? Am I just issued another certificate that I paid this years taxes or will I have rights over the property? Should I foreclose immediately or am I supposed to wait the 3 years post? Am I issued some sort of deed after 3 years of paying? This really turned into a money gimmick it seems.
