Investment option with 4 million in lahore/karachi/rwp/isb

Dear all
I am looking for good investment options in any of the major cities mentioned above for 3 years. I am currently working abroad and need to employ my savings instead of keeping them in bank.

My budget is around pkr 40 lacs for down-payment and upto 9-10 lacs per quarter installment if required.

I have visited bahria karachi so far , i am currently in lahore and plan to visit islamabad next weekend till eid so the choice is open.

Thanks for your support
