Any advice for Tax Lien starters?

[Jack Zuchars]

Toying with the idea of tax liens. Mostly because it seems to involve somewhat lower cash outflow. My questions to the group are,

-what should I absolutely watch out for?

- I've heard FL and TX are good states to start with tax
liens, is it true? Any advise here?

- I find it hard to believe someone who is behind on
property taxes will pay the lien holder back taxes and
15-20% interest! Do Lien holders almost always end up
evicting the owner? Isn't that a long process?

Thanks again.
