I actually bought land, a vacant lot right outside the city. I was planning to build a house and a big garden on the rich soil. Until I discovered that the entire house that once stood on it had been buried in it. Since it was built before 1970 lead contamination is a certainty. Also I learned from a neighbor that the boomer kikes who sold it to me at a bit below market rate bought it from the county for a pittance just 5 years ago.
As for buying farmland, I also looked into that, and everywhere outside of remote arid shitholes it is outrageously overvalued. Especially anywhere within an hour drive of a city. In very rural areas it's more reasonable but there are only like 500 acre parcels for sale. On average it takes something like 50 years of leasing out farmland to pay back the cost of buying it. Although inflation somewhat helps. That's why the only ones who can afford to buy farmland are billionaires and investors looking for a place to park their capital as a hedge against inflation. But it's in a huge bubble that cannot last seeing how financially assfucked the average farmer is.
Then the elephant in the room is the number of boomer homeowners. Once all those old fucks retire, as they are just starting to en masse, and an economic crisis likely guts their 401k and other income streams, they will no longer be able to afford living in a mansion alone while having a payment on their heavy duty truck, RV and boat all while their kids live 1,000 miles away and can barely pay rent. Either they will be forced to sell their mansions and move in with their kids or vice versa. Either way the supply shortage will quickly turn into a flood of supply as people are forced to stop being financially retarded. Might not happen soon but it will at some point, it's inevitable.
