It'll cost them a fortune to keep pylon palace but I'm not sure they could afford to sell it either. They won't get back what they paid because new build premium, Creepy's shoddy DIY and landscaping, and their own YouTube videos talking about how badly built/finished it is. Moving costs money obviously (although luckily they do have the world's most spacious delivery van handy...), their finances are on a downhill slide so no guarantees they'd get a new mortgage or be able to rent something big enough for their egos, and I know it barely matters at this point but it's not going to do the channel any good if they have to downgrade their 'dream home' to something less farble-y.
