How saturated is the tax lien investing?

[Chad McIver]

Ive done some research and reading on tax lien certificate and deed investing, and alot of the stats and books are typically pre 2010.  Are double digit returns obtainable still?  What states are ideal?

@Chad McIver A lot of hedge funds have gotten into tax liens since their cost of capital is so low they can acquire these, get their returns and not own the property
