Buying plot in DHA Valley?

I am planning to buy plot a 5 marla plot in zinia block in dha valley. What is the expected price range?
Also, what is buying process for dha valley?

Zinnia corner plot is around 85 thousand profit.

The procedure to follow is that you should get a fresh open file (no one's name). You pay them the due amount after verifying the file from DHA. Make sure to get all payment receipts as well.

Never heard of zinia buy in front sectors
