Gary, has she checked land over near Harrison? Probably not cheap, nothing is, but I would think cheaper than Rogers area.
I would second this suggestion... Rogers, Bentonville, Springdale, and Fayetteville have turned into a giant continuous megalopolis. Hard to tell where one ends and another starts. And it just keeps growing. Everything along the 71/49 corridor is exploding.
If you like the country life, shop a bit further out.
SW Missouri and NE Oklahoma aren't far from there at all... I can be in Rogers in an hour, sometimes a bit less.
