After careful consideration, we've decided to stay put. Too many "cons" for us and too many trade-offs for worse quality of life. Simple advice to those still looking: Money isn't everything, so be very clear about what you are looking for in ME. For us, it was an opportunity to have a temporary base to travel globally more frequently (we live in a remote part of the world now).
Again thanks to everyone who replied to me.
Adios
