"Good salary"

You can not just look at the salary. You might be offered this allowance, that allowance or school fees.

Here are my thoughts

Car - One SUV around 5,000 per month to rent
Car - One small for your work journey 2,000 per month to rent
Petrol is cheap - 13p per litre

Housing - Is more expensive than UK. 15k would get you an ok villa. It wouldn't get you a four bed in the Pearl.

Food - It is Waitrose price for Tesco quality.

Schooling is around 40k per year.

Flights - Do you get just the basic or will they up it.

Health care - Is it full private or just 80%. Does it include dental.

and the list goes on.
