In Newtown, PA there is a house for sale that has 3 bedrooms, 2 bathes and is 1,579 square feet. The asking price is $420,000.
The unusual feature in the house though is a toilet located on the steps. I guess if you can't make it to the bathroom upstairs or downstairs in time you can stop and use this toilet.
