I have decided personally that it makes more sense to buy large-cap stocks or industry-specific ETF’s (exchange traded funds) because the management fees are low, and it is easy to get in and out.
Everyone’s risk tolerance and investment goals are different, but I would definitely avoid land in the middle of the desert without mineral rights or “regular” water (i.e. not from wells).
Land is so illiquid, and speculative, that it does not seem like it would an investment suitable for almost anyone’s retirement.
