Being a pro golfer must be great. The prize money is very appealing indeed, you get to wear snazzy trousers all the time, and it's the kind of sport in which you can maintain your professional standard well into your 50s. It just looks like ruddy good fun. And on top of that, the courses are famously pretty places. So when someone says there's a £1.7m mansion for sale practically on the grounds of one of the country's most prestigious golf courses, your ears will probably perk up.
