Hi @Ran Fridman
Tax liens and deeds are very different from state to state and may be very complex investments. You need to understand the laws/rules for each specific jurisdiction where you want to invest.
There are more detailed answers to your questions in previous BP threads but as a quick answer:
1) Typically a lien or tax deed cannot be acquired before an initial auction. There are some special cases in some jurisdictions but they are not relevant to the average investor.
2) Depends on the jurisdiction and their publishing requirements. Each County typically has a site that may contain a listing. Else, they may be maintained at the site of the law firm that processes them for the jurisdiction.
3) Most will require a known local entity (ie a business registered in that state) or a person. The entity must be formed so that it can legally hold property. How you structure this is also a question for your CPA.
