im also a UK expat on a similar salary and i think its a good offer. my advantage is that i dont have family here but it is a good salary. u can also find villas for around 10,000 per month and buying a car could work out cheaper.. u will have to research schools as that is the biggest expense depending on the age of your children.. good luck! iv been here for nearly 2 years, not the best place in the world but i love it here!! :-)
