The huge returns being made from Dubai property investments has pushed the prices up for locals and expatriates wishing to either buy commercial or private property worry about being able to afford to live in Dubai the mortgage repayments are often significantly higher than rental payments. Due to high demand and rapid growth particularly in apartment and seaside dwellings building costs have skyrocketed. Some market experts predict a slump or a correction to prices by a reverse trend sometime in the near future. To date however there appears to be no slowing down and demand way out exceeds supply. The fast profits being made have lead to a worldwide awareness and a rush to invest and as a result there have also been dubious realtors and scams being conducted.

If you are considering buying commercial properties in Dubai then it is prudent to do your research first. You cannot expect to just jump off a plane and find yourself a profitable short-term investment. Foreigners in particular need to be wary and get sound advice before even considering a purchase. As an investor you cannot apply other market results to expectations of returns. To avoid being scammed or sold over priced properties then you really need to spend some time having a trusted person look over any prospective deals and comparing them to others in different regions. Never buy a property unseen.

Dubai’s government opened up shop for those of any nationality in may of 2002 this lead to an overnight boom in the real estate market there is however no guarantee that this will remain the status quo.
