Investment advice lahore - dha

Aoa,
I am looking for some advice and will be grateful. For investment of 4.5 million, which one should be preferred? Dha phase 8 z block or phase 9? (5 marla plot)
Phase 8 z has not seen much appreciation at all, whereas prism r block 5 m has seen some appreciation. Will z block see price increase around pocession?

Appreciate your help. Thanks,
