Bulgaria was among the countries offering greatest return of real estate investment, aboutproperty.co.uk said.

According to official statistics investment return rate increased to 137 per cent over the first four months of 2006. In comparison, the figure was 116 per cent at the beginning of the year.

Some of the main factors behind the increase were the low mortgage rates and deposit requirements. These registered a decrease from seven per cent to 5.95 per cent, the site said.
 
The year-round tourism industry and the inexpensive airline ticket prices also added to the investment-friendly environment. The stable real estate market would be further strengthened by the country's expected EU accession in 2007, aboutproperty.co.uk said. 
 
Poland was also listed among the countries offering high investment return rate. After its EU accession in 2004, the country registered an increase in real estate prices from 20 to 30 per cent. As property prices were considerably low, the investment return potential was high, the site added.
