There is so much mythology surrounding Omaze. People don’t want to view it as a basic gamble - you buy a ticket, money is split between their profit and a good cause and there is a tiny chance that you might win a valuable prize - so they come up with all manner of objections to the whole concept.
The houses may not be worth as much as they say, but you get a large cash sum to live on until you settle in, they are fully furnished and include conveyancing fees. The company has to abide by the law, so if you have a dodgy financial background (eg money laundering, not being behind with a gas bill) they will check you out.
The cynicism is crazy. Even if you don’t win a house worth the headline £Xm you’ve got a huge return on your £10 ticket price, and £Xm minus a bit of exaggeration is still a good prize. How do people know that the houses are unsaleable? They tend to be unusual, often a bit remote (if not in London) so won’t sell as quickly as a standard semi on a bus route. So what? The winner didn’t pay for it anyway. I wonder if people think that doubting everything makes them seem less gullible and therefore more intelligent?
