I'm still learning myself but I'm thinking it should be: 'se les va a encantar la casa'? they are going to love the house!
Edit - your sentence was correct - 'les va a encantar la casa' with the meaning - they are going to love the house (thanx Laz)

That would be "Their house is going to get enchanted" (=bewitched). The original sentence is correct, and it matches your translation. "Encantar" is used exactly like "gustar" in Spanish... or "disgust" in English, although the meaning is the opposite.
