Short Term Investment

I have approximately Rs. 7.0 to 7.5 million. I am looking for investment in property in Lahore for about 6 months to a year time frame. Some experts recommended me these options:

Buy a plot in DHA Town (5 or 8 Marla)in Lahore
Buy a 5, 8 or 10 Marla plot in Y block of DHA Phase 8 Lahore.

Buy a file of 1 Kanal or 10 Marla in Z block of DHA Phase 8 Lahore.

I am not really clear where should I invest my money for best ROI in a year's time frame. Can you find sometime to help me and guide me for better investment. I want to remain in DHA Lahore for secure and safe investment.

Thanks in anticipation.
