Medium to long term investment 3-4 years in 1.5 to 2 million in islamabad

I want to invest 1.5-2 million in a plot in islamabad/rawalpindi
Someone suggested me buying an 8 marla file in dha valley which according to them is safe for 3-4 years but personally i dont like location of valley. However, if i invest their pls suggest block
I also saw pechs & university town as one of options
Motorway way city is another option
Please need your suggestions on where to buy or what else are the safe options which can give better return in this time

Try to go for a possession one for 2 million rather than files.

The following videos may help a bit.

Thank You Imtiaz Bhai

Any other expert please comment @Nadeem Bhai, AQ, Falcon???

Capital smart city looks good to me as there are rumors which are quiet authentic in property sector that DHA is going to takeover. I am sure if this happen people will get the profit.

I also heard that rumor that DHA is going for a farm houses project in Chakri, is it true?
