I can pre-warn any newcomers that although rental prices have dropped, Dubai is still not a cheap place to live. Dont be blinded by the attraction of a tax free lifestyle. Rents and mortgages will soak up a large amount of your salary. General cost of living is higher here than in the UK. Local banks typically offer home loans at 6-7% APR

If you decide to join FD, join because you want to and because you know that you and your family will be 100% happy here. This place is not for everyone! It's a small place to live and the extreme temperatures during the summer months limit your daytime activities.
