This week the most expensive house in America hit the headlines, thanks to its £270 million ($350 million) price tag.
The sprawling 10-acre estate in Bel Air, LA's neighbourhood for the super rich, is more than four times more expensive than Britain's priciest home.
London is notoriously one of the most expensive property locations in the world.
But in the UK capital acres of land is a luxury even large amounts of money can't buy.
The priciest home on the market in the capital at the moment is a seven-bedroom property in exclusive Chelsea.
It's a comparatively modest 10,000 sq ft, but has an asking price of £57.5 million.
This is 180 times more expensive than the average home in the UK, currently £316,000. As the saying goes, when buying a home, it's all about location, location, location.
So where will buyers have to fork out the most cash?
