MRG Group Sohna deals: Are spot discounts real?

MRG Group ke projects mein Sohna, Sector 58 mein spot discounts kitne real hote hain? Renting se toh pak chuka hoon, ab apna ghar lena hai. ₹1.5 Cr ke budget mein 3BHK dekh raha hoon. Brokers bolte hain ki "spot discount" mil jaayega agar aaj book kiya toh. Sahi mein kuch milta hai ya yeh sirf pressure tactics hain? Kitna realistically bargain kar sakte hain builder se? Also, brokers usually push for direct builder deals. But sometimes secondary market mein better negotiation scope hota hai, right? Especially for a 3BHK around ₹1.5 Cr. Any hidden charges jo baad mein surprise karte hain, apart from stamp duty? Like PLC ya maintenance ka extra? Dwarka Expressway connectivity ki wajah se price already high hai, aur kitna upar jaayega?
