Pre-launch pricing in Noida Extension: My Dubai perspective.

Pre-launch pricing in Noida Extension seems like a total gamble now, honestly. I'm based in Dubai and can't do site inspections myself, so relying on community info. Thinking of investing in a 2BHK around Gunpura, maybe with Homekraft Construction. What's the real all-in cost for something like ₹70-80L? Builders quote one price, but phir stamp duty, registration, PLC, parking... kitna extra lag jaata hai? Should I consider construction-linked payment plans or just go for a down payment deal? Is early-bird discount actually a good deal ya baad mein better offers milte hain?
