Giving a luxury food hamper as a housewarming present is a solid bet; they will be appreciated and may be as inexpensive or as pricey as you desire. Fill them with various sweet delicacies and homemade preserves... You may also buy a pre-filled hamper and adjust the contents to fit the person you are giving it to, attach a card with a special message on every item, and attempt a variety of ideas from the simplest to the most creative, and they will both be welcomed with appreciation from the receiver.
