Ghaziabad property: Ready vs. waiting game dilemma

Under-construction risk is completely overblown in my opinion, but my parents keep stressing about it. I'm trying to decide between Shree Apartment and Vandana Apartments in Ghaziabad. Vandana is completed, which sounds great, but its resale market seems a bit slow. Not sure if that's a red flag. For Shree, I'm worried about potential construction delays and hidden costs. Has anyone bought in either? What was your actual total cost of ownership for Vandana, including everything? Should I just pay more for ready-to-move, or is the wait for Shree worth it? Ab samajh nahi aa raha.
