Most private schools cost about the same or more than UOP. Of course, there are a couple exceptions like Loma Linda. With the hikes in UC tuition thanks to the Gubenator, Loma Linda is actually the cheapest CA school now.
Being chepaer than UOP isn't the exception, it's more the norm. Some that are cheaper: Arizona, Loma Linda, Howard, Nova, Harvard, Creighton, UNLV, Columbia, Case, Temple, Meharry, Virginia Commonwealth, Marquette.
So, roughly 90% of the private schools costs LESS than UOP. Some by nearly $100,000.
