I remember specifically hearing all the reasons back then why land prices would stay high. Some were: “they are not making any more of it”, “farmland is disappearing because of urbanization”, “have to feed the world”, a subset of that “China”, “investors taking their money out of equities markets and into “real assets””.
There were more but can't recall them.
Last year, and my cousin leveraged a few 100K in farm land, I reminded him of that. He just said that things were different now and that he had to grow to survive.
Honestly I hope he guessed right, but my uncle told me that they are one bad harvest from losing most of it.
