New Delhi mein kaunsa builder on-time delivery karta hai?

₹1.8 Cr for a 3BHK in Dwarka is what I'm seeing, but not sure if it's the right time. I'm based in Dubai, can't do site visits myself. Thinking about DLF, Godrej Properties, or Tata Housing projects in New Delhi. Kya inka delivery track record sahi hai? On-time possession kitna reliable hai? Also, construction quality ka real feedback chahiye, matlab, seepage ya finishing issues toh nahi hain after possession? Aur booking ke baad customer support kaisa hai? Power of attorney se sab manage karna padega, so reliable info bohot zaroori hai.
