Have a question about a passage in my real estate textbook

[Brandon Snyder]

Hey all.

I'm going to take a class to start getting my real estate license at UCLA (class starts later this month), and I'm reading a passage in my textbook that was badly written.  I'm hoping any of you can help me make sense of this.  I'm re-typing it word for word.  The bold sentences are what I have the most difficulty with.  Does "the greatest ownership in real property" mean whoever has the greatest ownership in real property?  What does "unqualified" mean?  Can anybody word this better so it's easier to understand?  The passage goes:

"An estate in fee, sometimes known as a fee simple estate, is thegreatest ownership interest in real property.  An estate that is unqualified, of indefinite duration, freely transferable, and inheritable.  It is known as an estate of inheritance or a perpetual estate because the owner may dispose of it in his or her lifetime or after death  by will. This is the most common type of estate that is transferred in a normal real estate transaction.  If the property is transferred or sold with no conditions or limitations on its use, it is known as an estate in fee simple absolute."

Thank you very much for your help!
