It is hard to imagine, much less find, a better exemplar of how capital gets misallocated in a bubble than British property agent Foxtons, whose stock was publicly listed last week. Foxtons, which only three short years ago was taken over by its lenders, went public and by the end of its first trading day was worth $1.2 billion (Dh4.4 billion).

That’s a bit more than double what it sold for in 2007, just before the crash, when its founder Jon Hunt sold out to private equity firm BC Partners in a deal which was at the time widely derided as marking a market top. To put it in perspective, Foxtons is now trading for a bit more than 20 times what investors expect it to earn next year.

That implies investors believe that either it will gain market share rapidly or, as real estate agent fees are a percentage of sales and rental prices, they think London real estate will continue its stratospheric rise.

How Foxtons came to command such a premium price, its journey on the way, and the policies and forces which got it there form a very short tour of what has gone wrong in Britain over the past decade and a half. House prices in London have more than tripled since 1998, rising far more than incomes and driven by a complex combination of forces.

Loose monetary policy

While difficulty getting planning approval has played a role, as has London’s popularity with rich foreigners seeking a bolt-hole against political risks at home, much of the gains have been driven by the financialisation of the British economy. With London perhaps the pre-eminent global banking capital, that created many very highly paid jobs, and people capable and willing to pay up for houses and flats.

Before the financial crisis, there was also the fact that British lenders would more or less lend to anyone, often with only their own testimony in support of their ability to repay the money. That allowed people not making financial services salaries to borrow, and many did, hoping that gains in property prices would justify loans which no sane banker would make.

That all ended with the crash, which began shortly after Foxtons was sold in 2007. London property prices tumbled by 16 per cent, Foxtons proved unable to handle its debts, and the banks moved in.

In a normal universe you would expect it to end there — bad loans and bad policies are followed by a crash and lenders mop things up. But we don’t live in a normal universe.

British and global monetary policy has been kept exceptionally loose since the crash, at least in part to support asset values. At the same time, while parts of financial services in Britain have been hard hit, a failure globally to adequately regulate the industry means it remains huge in relation to the rest of the British economy.

Rising prices

Britain seems unable, politically or otherwise, to wean itself from its addiction to property price gains. Exhibit A is the government’s Help to Buy scheme, under which the state subsidises mortgages by guaranteeing a portion to the bank, allowing borrowers to buy houses with as little as 5 per cent down. That’s active for new properties now and will shortly be allowed for existing homes.

Sound like state-sponsored subprime lending to you? Nice for banks and older property owners who can cash out, but not so good for ordinary people trying to buy ordinary houses on ordinary salaries.

All this has also not been great for Britain, as is shown by the fact the economy has even now only clawed back about half the 7.2 per cent of output it lost in the crash. It has however, been fantastic for London property prices, and by extension for real estate agents in general and Foxtons in specific.

Prices in London are now 6 per cent above their pre-crash peak and are rising at the fastest rate in nearly seven years. For Foxtons it has been a wild ride.

The estate agent was partially taken over by its banks in 2010, at which point its private equity owners injected cash and kept 30 per cent, with management also retaining a stake. Just two years later BC Partners bought out its banking investors in a deal which published reports said valued the company at about $400 million (Dh1.5 billion).

That compares to the $1.2 billion the stock market says it is worth today. The lesson?

Government policy works; in this case it is working to make London houses expensive and to divert capital and talent to flogging them.

Good luck with that.
