There's a dangerous mentality which comes across farmers frequently. The neighbor is getting out of farming for whatever reason and putting their land up for sale. Land is typically held for decades, and having any of your neighbors selling their land may never happen again in your lifetime.
So farmers end up paying ridiculous amounts of money for land which will give them a very small positive, or often a negative, return on investment.
And good luck if you want to get into farming. The capital expenditure is ridiculous, even just for 40 acres of land. Medium quality farmland was running $6,800/acre in 2017. [1] $272,000 get you 40 acres without buildings, equipment, animals, seeds, a well, etc. It's so easy to hit $500k even if you went with used equipment. If you tried this, you'd probably want to build your own brand and get people willing to pay a significant premium for your product rather than trying to grow commodity products.
