Sam Palm Grove: Resale market's real pulse

My portfolio needs diversification, so I'm eyeing Noida for an investment property. Sam Palm Grove Apartments, Sector 150 mein, shortlist kiya hai. Price range ₹1.8 Cr se start ho rahi hai. I work in real estate but buying for myself is a different ball game, yaar. Builders ki marketing spin toh I can see through, but ground reality alag hoti hai. Ongoing project hai, toh builder ka delivery track record kaisa hai? Time pe possession denge ya delays honge? Also, long term investment plan hai, toh 5-7 saal baad exit strategy ke liye resale market kitna liquid hai wahan? Matlab, kya end-user ratio decent hai ya zyada investors ne le liya hai? Ghost society toh nahi ban jayegi?
