Ranch Prices

How are the prices will change in the coming years?
I am 14 now and trying to decide the amount of money needed to saving for future ranch. How much are prices likely to go up (or perhaps down) by then? Not only in the cost of land, but in general.
They are rock bottom more or less at the moment, so hopefully that goes upstairs. If they do to the economy will never recover.
