Hispania, created by Spanish-based private investment firm Azora, last week announced plans to list on the stock exchange and launch a share offering in order to raise 500 million euros from qualified investors.

It will operate as a real estate investment trust, or REIT - listed vehicles that typically invest in income-producing assets, such as rental properties.

Azora, George Soros and John Paulson were not immediately available to comment.

REITs are taking off in Spain, where they are known as SOCIMIs, as foreign investors hope to cash in on the country's economic recovery and search for real estate bargains following a 30 percent property price slump since a real estate bubble burst six years ago.

Outpacing Hispania, Spanish family-owned real estate company Grupo Lar said on Friday it would list on the stock exchange in a 400 million euro deal, priced at 10 euros per share.

George Soros has in recent weeks stepped up his investments in Spain and in European real estate.

He was last month an investor in the European property unit of U.S. real estate investment fund Kennedy-Wilson Holdings Inc (>> Kennedy-Wilson Holdings Inc), which plans to make acquisitions in Britain, Ireland and Spain.

He also made headlines in January after buying shares into Spanish building company FCC (>> Fomento de Construcciones y Contratas SA) .
