Gurgaon under-construction projects: What's the real deal?

My lease ends in 3 months and I'm honestly panicking about finding a home. Itna time ho gaya renting, ab toh khud ka chahiye. I'm eyeing a 3BHK around Golf Course Extension, Sector 65. M3M ka ek under-construction project dekha. But yaar, builder payment plans have me worried. Dost ka experience bahut kharab raha – hidden charges, delays. Matlab, EMI chal rahi hai aur possession ka pata nahi. Ready-to-move lena sahi hai kya, even if pricier? RERA ne kitna help kiya hai? Anyone faced similar issues with under-construction in Gurgaon? What did you do? I'm worried about getting stuck.
