Budget finalised, loan pre-approved – now the real hunt begins

Budget finalised, loan pre-approved — but ab builder choose karna sabse mushkil lag raha Gurugram mein. I work in real estate, so I know the marketing spin, but buying for *myself* is different. Looking at DLF, M3M, and Godrej projects, especially around Dwarka Expressway. Kya inka on-time delivery track record sach mein acha hai? Ya delays common hain? Aur construction quality ka kya scene hai? Bahut sunte hain ki possession ke baad cracks ya seepage issues aate hain. Plus, hidden charges like PLC ya EDC, kitne unexpected hote hain? Builders toh mention nahi karte. Any real experiences with their customer support post-booking? Do they ghost you or actually help? Need honest opinions before I commit. Thanks!
