[Beetlejuice] Adam & Barbara Maitland didn't die in an accident. They were murdered!
By none other than their rudely overbearing realtor, Jane Butterfield. From the very moment Jane jump scares her way into the story she's hot on the Maitland's asses to allow her to sell their house, and it's noted, that they've refused repeatedly. Adam & Barbara go into town almost immediately after Jane leaves their house and are killed returning home when their car goes off a bridge to avoid hitting a dog.
I propose that after being refused too many times and in need of a commission to care for her weirdass, sickly son, that Jane cut the brakes of the Maitland's car which is why they couldn't stop from going off the bridge. Damage to the car hid Jane's sabotage and she walked away scot free with a hefty commission after a quick turnover of the house to the Deetz's.

That would explain why they are ghosts doing a haunting instead of moving on. Unfinished business and foul play leading to ghosts and all that.
