Sohna buyers: Under-construction risks worth it?

Visited SS One last weekend. Upcoming projects ka price toh theek hai, but under-construction ka gamble samajh nahi aa raha. Possession delays ka darr hai, aur mera landlord ne phir rent badha diya. Ab bas apni property chahiye. Should I risk SS One for the potential ROI, ya ready-to-move ke liye stretch karu Sohna mein? What's the real possession risk with builders nowadays?
