Do you know anything about farming? Do you think you will receive a premium for the iliquidity of your investment?
From what I've heard, it's a bad investment, not liquid, depending on locals to farm your land and not steal from you (unless you intend on plowing the fields yourself).
Lots of scams promising high yields on Nut farms in Latin America/Durian farms in Malaysia/etc/etc/etc have duped countless Doomers to invest and never see their money back. Please do very deep due diligence before you waste your money on this.
The people I have seen who have done it have all underperformed the market significantly︀ but they can at least claim they have some farmland in some godforsaken place in︁ case all hell breaks loose. If it makes you sleep better at night, then I︂ guess it's worth it.
