Some investors believe the only way to accomplish anonymity is by using the Wyoming LLC, which is not true but it could add to the advice you are getting.

Quote from @David Little: Generic advice from a non-attorney.An LLC is useful for two things: anonymity and legal protection.

Basically the WY LLC that offers anonymity and charging order protection owns the TX LLC (or a TX series LLC).

They can provide some modicum of anonymity, and are great tools for estate planning, but they aren't designed for asset protection.

The business trust (Delaware statuary trust) provides asset protection, anonymity, pass through benefits, no LLC filing fee, and the banks don't care given the owners are the same as the trustees.

You can also walk into the local building department and ask 'anonymously' to find out if they are required.

So, do your research but if you have specific questions about the property code violations, you might stay anonymous to the code inforcers as you ask the questions.

Anonymity is nice, but if you will be the one making offers, cleaning it up, hiring contractors, buying insurance, screening renters, signing leases, etc. you probably won't have any anonymity.
