My newest online time suck is a little website called Historic Properties. It lists historic houses and buildings in all states of repair/disrepair - from an exquisite pristine condition multi-million dollar estate to a 15K church to an old theater. Many are in the South (apparently old historic property is free down there...), but I've managed to find a few local Midwest gems.
This Glenview, IL house is only $1.
Or how about one of John Deere's old residences for only $182,500
Or maybe this 5K shotgun shack. Shotgun not included.
