I bought 150 acres for less than the list price on the place you posted a link to above, but it had no improvements. However, my pond is down in a low spot, near a drainage which drains 1200 acres! Look for something like that and you won't have to worry about water (except in years like this one).

Again, it isn't that hard to know if the property will be able to hold water or not, with a little educated kicking of the dirt so to speak, noticing ponds (or not) on neighboring properties, and talking to knowledgeable folks.
