Trying to find a movie i saw in early 2000,s. I believe it was the House that Jack built, or Jack’s house, or Jills house,

Handyman starts helping family around house or something to that effect. Eventually the man turns murderous and starts to terrorize this family. The big twist was the man is an impostor and is being manipulated by an old woman in an asylum who for some reason wants the family dead, During the big reveal it shows visions of this lady as the man talks to himself with his hand.
