Noida Extension resale market is way too slow.

Noida Extension mein Real Shree Shyam Villas dekh raha hoon, but kuch doubts hain. I'm in real estate myself, so I know builders' projections can be... optimistic. Pre-launch rates vs current ₹1.29 Cr–₹1.45 Cr, kaafi jump hai. Is this appreciation sustainable for investors ya just marketing hype? Secondary market kitna liquid hai yahan? Investor ratio high hai toh exit strategy mein problem toh nahi aayegi? Off the record, what's the real resale potential here in 5 years?
