Influx of multifamiles in the midwest

[Blaine Alger]

I have been browsing the national market recently looking for multifamily properties and I have noticed the abundance of duplexs, triplexes, etc in the states of the midwest. They all seem to be  reasonably priced and in fairly good areas. I understand it is a different  market then what I am used to but 100 to 200 thousand for a duplex or triplex seems like a pretty good deal. Does anyone know why it is so much easier to find a multifamily in this region than anywhere else?
