It's possible the house is under contract and still hasn't closed for whatever reason (the buyer's stipulated X months until they take possession or sell their existing home, modifications they want made to the property, or issues that popped up during a thorough inspection that need to be addressed by Allison and Donovan, etc).
Or it could be the usual real estate sites haven't gotten updated deed transfer info from the city/county clerk's office.
I do appreciate that the show is pretty straight forward about overages, sale/no sale, and the like. I think they'll break even on this one or walk away with a very small profit.
