There is a house with 7 foot ceilings in our neighborhood. It has been on the market since 1999, no kidding. The owners did manage to rent it out from 2002 until last summer (2007), but now it is empty again and the realtor's sign is back up.
However, this isn't an "old" house, it was just a design screw up. From what I understand, the original owners wanted the floors to be 2 feet underground in their original plans, but when they got to the point where they were going to have to pay someone to do the digging/dirt removal prior to pouring the slab, they decided against it because it was going to be expensive. However, the builder still only built the house with 7 foot ceilings from ground level to ceiling per the original plans. The owners and builder got into a dispute that was settled in court (not sure of the outcome) but the bank ended up with the house and sold it to the current owners.
