You will find that a 2 bed villa will cost you about on average 14,000 -16,000 dhs per month...so no, I wouldnt say it was viable. (please remember that that figure does not include 5 % agents fees, and rent is generally paid 1 year UPFRONT)

It will depend on what job your partner has, but I doubt they would make half (with office jobs etc)

Are you married, as you will not be able to sponsor your partner at all.

30,000 dhs is more doable...but I wouldnt commit to that amount unless you KNEW thats what your earnings would be.
