The soil is fertile and will grow grains and cotton just fine. It is true there was a severe drought from 1916 to 1918, but the rains seem to be returning. The crop you are thinking about growing is grain sorghum since it can usually make it through dry weather and you don't have irrigation water available. The main use of grain sorghum is a feed grain to fatten animals and you have some doubts about the ability of people to afford meat. The main attraction to this farm is that you can afford to buy a place that's big enough to grow a lot of crops.
Land prices are still low because of drought.
The second possibility is a grain farm in Swisher County on the High Plains. This is an exciting possibility because Swisher County is getting irrigation water from the Ogallala Aquifer now. That aquifer is over 500 feet below the surface and has millions of gallons available for pumping. The natural grassland is very fertile. Since the land has not been farmed, there is little problem with disease or insect pests except for the grasshoppers.
