If you’re considering selling your house, making a good first impression for people viewing is vital. Everybody has their own tricks, but one man in Holland has taken things to another level. He built an entire roller coaster that guides people around his house, and it’s the most genius bit of real estate advertising I have ever seen. With the help of Dutch bank AB AMRO, he’s created something that will definitely leave buyers with a huge smile on their faces. Forget tea and cookies, every open house should come with a free rollercoaster ride!
