I guess you mean 75,000 American dollars per year?
If thats the case, that equates to approx 270,000 dhs per year.

In my opinion, not enough.
A 3 bed villa is approx 200,000 per year (paid up front)
You may find some less expensive, but usually means they are further out of city, under flight path etc
An apartment may be cheaper
Depending on ages of kids, you would need to allow at least 40,000 dhs each per year
A car you would easily get for under 2,500 dhs per month
cant help with insurance
Utilites in a villa would range from approx 500 dhs per month-anywhere up to 3,000 dhs (costs are higher over summer with air cons on all day/night)
Food..depending on how much you eat out, but I would say min 2,000 dhs per month.

If its in pounds, you will get a little more for your money.
