Could you be a creditor claimant?

Even local courts may have local rules.Generally, legal publication such as "Notice of Petition" to creditors and other potential claimants will not provide you sufficient actionable information to market and merely notifies others that a Decedent's estate is being probated.You can monitor obits and research if decedent owned property.You can use the legal pubs to pull indivisible files at the courthouse as well as those  that did not require legal publication.Alternatively, you can pay a researcher (whom you are likely to find at the courthouse records researching files) and pay them to collect data to your specifications. 

The second issue is a liability as, in theory, the LLC provides a layer of protection in that the potential claimant can't penetrate into your personal assets; the LLC would simply file bankruptcy, and that would be it.

I'm not an insurance agent or adjuster but unfortunately have some experience from the claimant side. 

If your LLC is sued, the claimant can seek damages from your LLC.

The 'counter notification submitted' image James posted above states that if the counter claim is accepted, it is sent to the claimant for review.

& liensTitle - All persons on record title Interests - All persons who are or would be claimants if any record owner deceasedOpportunities - List if ways to monetize the asset (fix and sell, fix and rent, develop, etc.)When you're "in the crunch" (deal time) it's pretty hard to tell your prospective seller that you need to stop and read a book or take a class. 

That is some miracle by a newbie success claimant!

Another claimant to the land sued him as a “trespasser.”

And as you said, most of the industry disagrees with you about notifying the potential claimants, which makes my point all the more.
