On topic, I don't know much about sink holes, but the hole in the second picture shows like the thread on a drill or something that had scraped against the side of the hole? Is this normal, or on par with other sink holes? Or is it possible this could have been a mine shaft or something caved in underneath her home? One of the comments suggests it may have been a well.
