Raw land is going for anywhere from $2,000 - 5,000 an acre. Our taxes are cheaper down here but you're state still has much cheaper land.
That is about in-line with our area, about $3K an acre, depending on proximity. Head north a little and it gets up to $10K an acre. I looked at a parcel in Fairport, it was $500K for 100 acres. A bit steep for overworked land, but I am sure a developer will snap it up and cram 200+ houses on it.
