That will help to protect you personally too in case legal action is filed on your business.  

Again, if you're going to get into holding the note or lending, you want to make sure you're protecting your investment (your cash) completely!

Our agent quotes some NEW law that supposedly protects buyer's financial details.

I was planning on vetting property, managing rehab, managing property mgt, managing finances (payouts, etc) managing LLC (asset protection strategy), etc., etc., etc. :)However!!!!

What should I do to protect myself?

I was given an answer by him, but I would feel much better if I was 100% sure that this property is TIED to the LLC and is what is protecting my investment.

It helps protect yourself for sure from the poorly trained legal people or from people that claim to be in the industry, BS and scam artists.

And the use-cost of placing the filing principals' address(es) for your LLC if you want this entity form to give your business (and you and your household) the asset protection (separation and anonymity) the LLC is designed to do.  

You will still want to have adequate Liability (includling an umbrella) but the LLC generally protects from the claimants going after your personal Assets.  

If he threatens you, I would file for an order of protection and no contact.
