No doubt you're looking at a short sale or bank owned listing. The owners will sell everything of value, including light fixtures. On a short sale, although the buyer wrote that the appliances will stay in the contract, oftentimes owners don't care and they'll sell them on craigslist anyway. So if you go after a short sale just make sure you are prepared when you do your final walk through the day before closing that the appliances, light fixtures and window treatments and garage door opener will be gone.
All the best,
