RTM ka premium in Noida Extension is getting too high, but under-construction projects still scare me.

RTM ka premium in Noida Extension is getting too high, but under-construction projects still scare me. I'm eyeing Sector 150, maybe ATS or Godrej. RTM 3BHK ₹1.2 Cr tak jaa raha hai. UC mein kam milta hai, but builder delays ka darr hai. I know the tricks, but still. Is the RTM premium justified now, ya UC mein risk lena chahiye?
