Nick...It's been a few years since I've priced farm land...But 8-10 years ago in eastern NC farm land was bringing $1,000-1,500 an acre...In Iowa, where you are it would run $1,200-$1,800 an acre...
Now, these are very rough figures and don't consider highway frontage, buildings, creeks, etc...

Here in NC, the growth of cities and developement is ruining the family farm...In 50 yearsif you don't own land in NC you probably will not be able to hunt on private land...
