That article has a link to the family blog, which has a photo of a WWII postcard they found in the building (with the address, confirmed with Google Street View). That's not even rural Indiana. It's a town within a 500,000 person metro area and about a 25 minute drive from the downtown of the central city, complete with skyscrapers and everything. The town itself has a very solid looking (streetview) walkable downtown area. I looked on Zillow and fixer-upper houses within a few blocks of this building are listed for $35,000 to $90,000. Really nice, immaculate homes in the area appear to sell for $150,000 or so. My guess is that $89,000 is right on target for this area, and I'd bet they spend multiples of that on restoration.
