(Bloomberg News) London's commercial property market will probably draw the most investment for the second consecutive year as prospects of rising rental income attract cash from as far afield as Hong Kong, Qatar and Canada.

Sales of existing commercial property in the U.K. capital totaled $13.9 billion in the first nine months, more than in any other city, according to Real Capital Analytics Inc. Some of the biggest deals of the year were announced in the final quarter.

"There's a massive surplus of investment capital looking for a home, and the one thing in common is a desire for yield," Dan Fasulo, RCA's managing director, said in an interview. "A core London office property at a 5 or 6% yield looks fantastic against the alternatives."

Cash-rich pension funds, sovereign wealth funds, insurers and wealthy individuals bought shops, offices and even luxury homes in central London as low interest rates and concern that the global economy will deteriorate made other investments riskier and less appealing. The city also ranked first in 2009 with sales of $16.8 billion, New York-based RCA said.

In the past two months, Norway's sovereign wealth fund agreed to pay 448 million pounds ($692 million) for a stake in Regent Street. JPMorgan Chase & Co. purchased a new European headquarters building for 495 million pounds. Dutch and Canadian retirement funds signed an 872 million-pound deal giving them part of the Westfield Stratford City mall next to the site of the 2012 Olympics.

In May, the sovereign wealth fund of gas-rich Qatar bought the Harrods Ltd. luxury department store for 1.5 billion pounds.

"Negative real interest rates mean you aren't going to buy government bonds, corporate bonds have already had an incredible rally, gold doesn't give you a yield and the stock market is volatile," Fasulo said.

Tokyo, New York

Tokyo ranked second after London based on existing commercial property sales in the first nine months, at $13.1 billion. Hong Kong was third, followed by Paris and New York. RCA's final rankings for 2010 are due in February.

If land deals for development are included along with existing buildings, Shanghai attracted the most money in the first three quarters, at $21 billion, the data show. About 81% of that figure is for development projects.

New York held the top spot in the world for commercial real estate sales in 2007, at the height of the debt-fueled investment boom. It slipped to second place after Tokyo in 2008, and to seventh place last year, RCA data show. In the first nine months of 2010, sales of existing New York commercial property totaled $5.8 billion.

London's Recovery

London was one of the first real estate markets to see a pickup in deals and prices after the financial meltdown. The recovery began in the second half of 2009, ending two years of declines that wiped 50% from central London office values. Property became even more affordable for foreign buyers as the pound dropped. Sterling is now 23% below its September 2007 value against a basket of other currencies.

In London's West End, where office leases cost the most in the world, rental income totals about 4% of a Grade-A building's value on average. The ratio, known as the capitalization rate, was 3.5% when prices peaked in 2008 and rose to as high as 5.5% a year later as the financial crisis caused values to fall, CB Richard Ellis Group Inc. said.

"You saw a huge weight of money coming in from overseas, attracted by the double-whammy of super-cheap pricing and the pound effect," said Damian Corbett, head of West End office sales at Jones Lang LaSalle Inc.

Investors may start to look away from London in 2011 as property in parts of the U.S. becomes good value again, said RCA's Fasulo. U.S. deals may double next year and account for almost a quarter of global transactions, he said.

U.S. Undervalued

U.S. offices are the most undervalued real estate in the world and investors have almost $100 billion earmarked for deals there, according to broker DTZ Holdings Plc.

Fasulo predicts "a wave of new investment" over the next six months in Manhattan worth about $10 billion. The average capitalization rate for a prime office building in the borough is 6%, and prices have scope to climb by about 4%, according to DTZ.

London's reign seems secure for the time being. Corbett estimates that there are 1,000 wealthy individuals looking to buy prime commercial properties in the British capital for as much as 200 million pounds, compared with about four in 2008.

Pramerica Real Estate Investors, acting for a wealthy family that it declined to identify, acquired Perella Weinberg Partners' London headquarters in Mayfair for 47.8 million pounds in September. The sale was at a capitalization rate of 3.9%, brokers NB Real Estate and King Sturge estimate.

Malaysia Fund

Malaysia's Employees Provident Fund announced plans in August to invest 1 billion pounds in U.K. real estate, citing the "stable and highly liquid" market and laws that secure titles and protect landlords.

The fund acquired 40 Portman Square, an office and residential building in central London, on Dec. 2 for 181 million pounds, or a capitalization rate of 5.57%. It bought Visa Europe's headquarters in Paddington for 156 million pounds last month. The purchases were confirmed by people with knowledge of the deals, who declined to be identified because the information is confidential.

Investors in London expect capitalization rates on properties they own to go up as rents increase, said Jason Winfield, who heads DTZ's U.K. sales department.

DTZ predicts that prime office rents in the West End will climb 38% to 110 pounds a square foot in 2014 from last year's low of 80 pounds. In the City of London financial district, they will rise 55% to 67.50 pounds a square foot. City offices are still priced 10% below fair value and West End properties are 5.5% undervalued, according to the broker.

Outside The Capital

The gains have been mainly limited to the capital, RCA data show. Elsewhere in Britain, concern about the impact of government spending cuts to reduce the national debt has held back property investment.

Tenants are competing for the best new office space in London after the financial crisis caused construction to slow. Drivers Jonas Deloitte estimates that office construction in central London is the lowest in at least 20 years, and the prospect of constrained supply has drawn some overseas investors.

Ontario Municipal Employees Retirement System acquired a 50% stake in the 340 million-pound "Cheesegrater" tower project in the City in October.

Money isn't just flowing into shops and offices. The euro region's debt crisis enticed more continental Europeans to seek a "safe haven" in London, where luxury residential prices are 14% lower in euro terms than at the peak in early 2008, according to Knight Frank LLP.

"Some of the uncertainties in other cities helped London," Fasulo said.
