If you must need monthly income then you don't have much options. You can save this amount in any Islamic bank saving account or Islamic mutual fund low/medium risk. Or you can buy an appartment and you will get monthly rent.
Since there is no support by government saving is very important.
Holding a plot can be an option if you have some monthly income coming on which you survive, if that's an option hold the plot. I hope with passage of time and development in dha city price will increase.
