Real Exchange Group delivery risk is real

Okay I'll be honest — I completely underestimated how confusing this process is. Greater Noida mein first property dekh raha hoon, especially Sector 77. Real Exchange Group ke projects dekhe hain, but under-construction ka delivery risk samajh nahi aa raha. Bahut log bolte hain resale better hai for first-timers, but new launch mein payment plan easy lagta hai. Kya kisi ne Real Exchange Group se liya hai? How to properly evaluate builder track record? Aur site visit pe kya-kya questions poochne chahiye? Honestly, I'm just lost on where to even start shortlisting. Any advice?
