Nope. On my mortgage, the mineral owners of my property were anonomous. If I wanted to find out who they were, I would have to go to the county and do a search.
Again, have you ever bought a house?
Another thing that caused me concern when I bought my properties, were easements. Meaning certain people have access right to my property in perpituity.
I was like WTF? Companies such as electric, gas, cable, etc. I understood, but legally there wasn't anything I could do if they wanted to have a sit down in my frontyard.
