If he's insinuating that the land is worth over $3M, he should sell it and buy a less expensive piece of land somewhere else.
3.49 Acres of Industrial Land Offered at $1,800,000 USD
Keep in mind, Carnes paid $750K for it two years ago. And it's commercially zoned, not Industrial like the comp he's mentioning.
Also, the improved property will be valued according to the income it produces. So even if the land is worth $1M, it won't matter to resale.
