I found this one listed for sale on Craigslist. They stated in the advertisement that they were getting $600 rent for a duplex in Rich Hill, I thought that was currious so I did some reasearch to see what you could rent in Bates County.
So it would seem that $300 a month is not that far from the norm, I doubt I'd offer them $65,000 but if the property is in good shape it might not be a bad deal at
