Ahmed. your main target is Monthly income.
if i were you then this what i can go for.
you can not get a monthly income from a plot. but it will be good for longer run. about scheme 33, i doubt, most of these lands are either non registered (some of the societies) and in my opinion its risky. i would rather go for Naya naziamabad (i am not their agent) its covered, and it was almost now in the center of city - karachi. A bridge has been approved from Nusrat bhutto colony (sakhi hasan kabrastan) which ends at Naya Nazimabad main gate.
Its very difficult to look what your driver is doing with the vehicle. if you go for Hiace for SWVL/Airlift. i dont go for it.
In the center of the city you will not be able to get a good flat. yes, it can be but not in the prime locations.
about stock market - only one like "humayun Saeed" can become a richer from rich.
about mutual funds - you are totally dependent on fund managers, you have options though like Normal, Medium and higher risk investments. but eventually getting exit on a proper time is worthwhile.
and we can not read the economy well - as a conflict between iran and US shattered every indices around the world.
rest we all can give you suggestions but eventually its your decision. Good luck
