Keya Homes HSR payment plans pe real leverage kaise milega?

Budget finalised, loan pre-approved — but ab Keya Homes HSR mein payment plans dekh ke dimag kharab ho raha hai. Unki construction-linked plan mein interest cost itna high dikh raha hai, yaar. Plus, super area ke naam pe itna inflate karte hain... lagta hai double payment kar rahe hain. Koi batao, builder se payment terms pe kaise negotiate karein? Is there a smarter way to handle this as an investor?
