The Acres.... What Goes In A Plat?

So as we know, the Eppstein Residence is for sale. The price has been reduced to $455,000. This makes it the lowest priced Frank Lloyd Wright that we can find in the US and the only one for sale in Michigan.

The Acres is located centrally between Chicago & Detroit as well as being located centrally between Kalamazoo and Battle Creek. It is also pretty close to central between Grand Rapids and South Bend.
