Views are difficult to price. Unfortunately, there is no "blue book" that we can reference that will tell you exactly what a given view is worth. The short answer is a view is worth what someone is willing to pay for it, which means it is worth a different amount to every buyer.
I agree with Carl. If you want the view, pay slightly more than your competition if it is a resale, or pay what the builder asks if it is a new home. Views of city lights in my experience are more valuable than golf courses in general, but it depends on the specific view you are talking about.
