Hello, i am egyptian as well but older than you. Listen you can accept the offer but do not expect to save a lot as you will pay almost 4000 for rent, about 1500 to 2000 as car monthly installment & about 3000 at least for monthly expenses without having too much fun. so you will be able to save about 1000 USD per month which is fine for somebody in your age. but if you are expecting to save more then do not come or ask for more.For furniture allowance it is going to be depriciated over 4 years but they will not pay it to u every for year check with them again,for end of year profit share do not expect more than two to three month for the basic maximum. also for promotions it is not that easy may be after 3 or 4 years.So you may accept the offer to gain the gulf expriance then you can start searching for another job in gulf as they always say for egyptians " you do not have gulf experiance"
