Unless you are a pretty good natural, at flying, and your school(instructors) are honest, you might finish with about 220 hours by the time you finish your CPL ME-IR.
Fly the rest as PIC, or do your flight instructor rating - excellent for you.
Life in SA is expensive. If you board, you'll pay through your nose but your quality of life may not be commensurate with what you are paying. On the other hand, if you stay outside, you'd better be very disciplined with time and money.
(Sorry, next comes unsolicited but important)
There are schools that delay your training i.e. you fly when THEY want, do exams when THEY want. This is not to your benefit.
Then there are schools where you decide when to fly provided that there's a plane and you have money to fly. You decide when you are ready for exams, book by yourself and go do them. If you flank, you try again next week etc (ideally, this would be in Jo'burg where the SACAA is)
It is not inconceivable to finish the entire course in 11 months - DO NOT PUSH this though - weather may not favor you and you don't want to die as a student pilot.
