this is a big family decision and if it all works out your 26k salary, tax free, and your husbands salary should allow u to have a pretty good life. However a lot of people come here, the job doesn't work out or whatever and they are stuck with repaying loans etc. with no resources. I recently bought a car, a little below market value, but he was paying back 16 k more to the bank than I was paying him for a car only 15 months old!
My advice is to come here by yourself if possible, do it now before school holidays, give it ur best shot, if u can survive the summer climate, snd the job works out, let ur family join u in september. By then u will know what hidden costs u will face etc. and more importantly, whether u can work under the restrictions common here in regard to sponsorship etc.
There was a lot of pressure on school places, etc. Do the research before you commit. QL is a good place to start as these problems have been faced by many people in the past.
You should remember that 26k is a fortune to someone earning 400 riyals a month, who has accommodation transport food, tickets home etc. as part of his package,
it is not a fortune to an American particularly when you add these hidden costs.
Research the market for your husband's work, if it's a blue collar or lower admin job forget it! he can't compete in this market with people happy to 1 or 2k a month!
