I don't care that this is technically an ad for a Dutch real estate company, or that it's also technically an ad for a guy selling his house. This is the most genius bit of real estate advertising I have ever seen, because they put an ACTUAL ROLLER COASTER IN A GUY'S HOUSE.
My only question would be if the roller coaster comes with the house when I buy it. That's the only way I'll make an offer.
