money pit

money pit

A business, possession, or other financial commitment that requires or consumes an increasingly large amount of money, especially more than was first anticipated. I bought this restaurant because of its prime downtown location, but with all the repairs and the huge amount of staff needed to run it, it's proven to be quite a money pit. The problem with buying used cars is that, even if they started off being cheap, they often turn into money pits as they start breaking down.See also: money, pit
