Remote Delhi property hunt: my builder dilemma

Okay I'll be honest — buying property in New Delhi from Dubai feels incredibly complex. I'm looking for a 3BHK, maybe in Vasant Kunj or Dwarka, budget around ₹2.5-3.5 Cr. Can't do site inspections easily, so I'm relying heavily on community insights. I'm considering projects by DLF, Godrej Properties, and Tata Housing. My main concerns are construction quality and post-booking customer support. For those who've bought from them in Delhi, how's the finishing *really*? Any issues like plaster cracks or persistent seepage after possession? Also, if you're remote, do they actually provide decent updates or is it a struggle to get information? Finally, any RERA compliance red flags or past legal issues I should know about for these specific builders? Need to ensure smooth sailing for power of attorney and future rental management.
