If one is hell bent on leaving Europe to come to the sand you should probably think of Qatar or the Un-mentionable before EK.
The reasons are they both pay more than Emirates when you consider everything including hours worked.
Also Emirates will probably have a 9-10 year upgrade if you join now. The other airlines you are looking at 3 years max.
Emirates has a 5 year training bond now but I don't know what the other airlines have, if any.
Inflation is skyrocketing in Dubai and won't get any easier especially with Expo coming. We as pilots will probably be paying the price for that in the form of lack of pay raise and stolen end of year Bonus.
To answer your question in the first post yes rents will be going up considerably.
Stay in Europe and enjoy everything it has to offer.
