Real-life prices on Monopoly board revealed Another area that has soared in price is Whitehall, which is only £140 on the board but a home there now costs an average £1,172,778. The average price in Monopoly is £208 but the modern equivalent for the same areas would be £788,106, according to the Halifax. Prices on the board have not changed since 1936 when the game came to Britain from the US and the values were converted from dollars to pounds. Soaring prices mean that not a single property in areas on the board would now be affordable to a Londoner working full-time and earning the national average salary of £26,500. Craig McKinlay, mortgage director at Halifax told the Evening Standard: "While drawing a comparison between the values placed on these areas in a board game and the actual average house prices provides a light-hearted look at the London property market, it does present a realistic picture of the capital's most popular postcodes. Many of the areas that have seen hypothetical increases from their board game positions are those which we have seen grow in popularity in recent years. Angel Islington is an example of this, surpassing its blue peers of Pentonville and Euston Road, by establishing itself as one of the capital's most cosmopolitan areas. The research was based on official sale prices from the Land Registry for homes in the postcode area over the last five years. More than 275 million sets of Monopoly have been sold across the globe since it went on sale in the 1930s. Its makers Hasbro have recently made a move to modernise the game by removing the iron token and replacing it with a cat next month.
