More and more people have been looking to purchase a property in Dubai in 2012, but which district should investors be focusing on?Of course, there has been a lot of regeneration across the city in recent years and there are plenty of high-class residences and exclusive regions within the emirate.Propertyfinder has conducted a survey which sheds some light on which areas of Dubai have the "happiest neighbourhoods".The organisation said there are three places where residents are more cheerful - Umm Suqeim, Dubai Marina and The Springs.Respondents were asked to rate their home based on a number of factors, including convenience, quality of facilities and attractiveness.Managing director at the property website Renan Bourdeau believes the results are interesting and have thrown up a couple of surprises.He feels the research offers investors a good indication of where they should be looking to buy.Meanwhile, Nikki Summers - managing director at Brix Property Partners - said she understands why these three areas topped the poll."Umm Suqeim offers large, luxurious villas with easy access to schools, supermarkets and of course the beach, which is great for families with children," she remarked."Dubai Marina offers young, executive living with everything on your doorstep like restaurants, bars and cafes."The Springs caters for young families and the peace and quiet takes you away from the hustle and bustle of Dubai."Figures recently compiled by Jones Lang LaSalle showed the demand for villas is particularly high in Dubai at the moment.Indeed, the average asking price for one of the luxury properties increased by 23 per cent in the third quarter of 2012 when compared with the corresponding period in 2011.It seems many people want to live as close to the sea as possible, which is hardly surprising.Dubai has a plethora of gorgeous beaches and the weather is usually beautiful, so it is no shock to see a huge clamour for glamorous villas that overlook the bay.Looking to make a property investment in Dubai?
