There are a couple of clues, in the movie, that reveal the location of the house used in the film.

First, when Carl and the boy (Frank) are toting laundry from the Econo-O-Wash to the boy's house, you can see a street sign that says "VINE ST" (see image right).

Later in the movie, you can see the house number (see image below-left).

By driving virtually, in Google maps, you can find that the house is located at the corner of Vine and South Main at: 522 South Main Street, Benton, AR 72015 (see image below-right).

As you can see, there is no longer a deck on the left side of the house (where Doyle's band played) and the left-neighbor's house is no longer standing. Last, you can't see any beer bottles sitting on top of a window-unit-air-conditioner (as in the movie), but that's the house!
