@Mark Gallagher - on the Lehigh County site I see that they specifically state those are separate costs:https://www.lehighcounty.org/Departments/Sheriffs-...But elsewhere, at least from what I have seen, the bid amount includes those amounts, thus reducing the net amount available for distribution to the various claimants.

The issue is the dangling, but highly unlikely, risk of another claimant coming forward later, especislly after you've significantly improved the property.Alternatively, you could spend the time and money to research the deceased Father's family tree, then skip trace any heirs and offer them something for their interest(s).

Adding your name to the policy may or may not be an issue if a claimant is trying to pierce the veil of the LLC to get at your assets.

My corporate structure makes the fight more complicated for them and my attack dog can also counter making things much harder for some average claimant.  

Your Father may be able to receive possessory benefits from his Father's house, however he is not the only possible claimant besides his siblings.

@Chris Purcell In my state you would have to either file a lawsuit against the claimant, or wait several years for the lien to drop off. 

When loan was made and property offered as collateral, it is possible that title or escrow, then lender, missed something;Blown sale or defect in foreclosure, occasionally procedural but usually concerns noticing;Or, Secured creditor or entitled claimant challenging bank's foreclosure.There may be other reasons.

You somewhat have to sort through the BS to get the few real facts because the claimant, of course, is always slanted toward their own views.

Actual' Possession - The claimant must physically possess the property in order to claim title [the fence...].'

Sounds like your claimant pulled a fast one on you.
