I can understand the need for a groundskeeper (or "caretaker") even when a house has been vacant for years. The grass is going to grow whether anyone is inside the dwelling or not. But the need for a maid or a housekeeper to come to work every day of the week in order to work inside a completely empty house is something that seems totally unnecessary to me.
And although she doesn't expressly come out and say so in the film, I get the distinct impression from the way Mrs. Dudley talks to the ghost hunters in "The Haunting" that she has established a normal routine and habit for serving meals at Hill House and leaving "before the dark comes". "I set dinner on the kitchen sideboard at six. I clean up in the morning," says Mrs. Dudley.
Oh well. Perhaps Mrs. Dudley has been serving meals to Vincent Price and Peter Lorre when she's not cooking for ghost hunters. After all, if she's been coming to work at a totally vacant house every day for years, she needs something to keep her busy. And Vincent was a gourmet cook too. So he can help her with those midnight suppers she's been cooking for Vincent and Peter.
