₹90L for 3BHK in Sector 28 – is floor premium worth it?

₹90 lakh for a 3BHK near Sector 28, that's what Skytech Group quoted for a new project. Fed up of renting, finally taking the plunge as an investor. Builder ka floor-rise premium aur PLC seems high, yaar, total acquisition cost badha deta hai. Is it genuinely worth paying for higher floors or specific locations in Greater Noida for future ROI? Ya secondary market mein better deals milte hain? Wahan pe negotiation ka scope zyada hota hai kya, compared to new projects?
