Upgrading from 2BHK to 3BHK – my Noida Extension struggle

Visited a couple of 3BHK projects in Noida Extension, especially near Sector 30. Pooja Infotech ka new project ₹90L+ bol rahe hai for a 3BHK. I'm already in a 2BHK and have a home loan. Secondary market mein negotiation ka kya scene hai, ya new projects mein hi spot discount milta hai? Floor-rise premium bhi bahut high lag raha hai. Is it worth paying so much extra for a higher floor?
