Cadets WILL NOT be offered any sort of housing untill it is proven that the current crop of icadets/adl instructors will not accept it ie leave so at a guess I would suggest at least another 12months but probably longer.
If CX is offering expats, local terms and people keep applying, why would they suddenly say they will double your wage.
Please don't accept an offer on the basis that you expect housing in the future, you are selling yourselves very short.
