As Mike points out,
it's all about what you pay.
I know the previous owners paid $1 billion (for what I assume was much more than one property)
But again, it's all in what you paid for the property, and again as Mike points out, what it costs to operate.
If everyone "knows" you can make a fortune owning Pebble Beach and "gouging" tourists, doesn't the price eventually paid to purchase it get bid up to where you have to charge "outrageous" prices to turn a profit?
What should Sebonack charge for initiation having paid $45 million for the property before building cottages, golf, clubhouse?
Seems like it'd be hard to charge less than $250,000 unless you wanted it to be really crowded in peak times.
