hey pj86,
Its an excellent idea to base yourself in dubai in terms of enhancing your career as dubai is becoming the central point for all major firms worldwide.

Regarding your first question, my guess is since you are being transferred from your country your salary should remain the same. Sorry dont have a lot of idea on that

coming to your next question. It really depends whats your budget. Nowadays, everyone in dubai is looking to buy property because its so cheap and with so many finance options available it doesnt really stress their earning a lot. Also it gives them an asset in dubai which they know is only appreciating by the day.

If you have any queries or require any assistance regarding properties in dubai do let me know. It would be a pleasure to help you.

Regards,
Sheryar
