Where is the best place or person to understand the rules

[Vincent Chen]

Just the beginner for tax liens investing, read books and posts of BP forum.

Understand the key of the tax liens is to details of the rules which determine the method and strategy and the rules differ from county to county.

So I would like to know that where/who is the best way to know all the details for the tax lien investing in the particular county?

Thank you very much
