10 years of renting, finally pulling the trigger

₹90 lakh for a 3BHK in Sector 150 feels like a lot, but I'm seeing prices climb fast. I work in real estate, but buying for myself is different – it's personal. I'm weighing two options: either a ready-to-move resale in Sector 78 or 107, or an under-construction project near Yamuna Expressway, like a Godrej or M3M one. The ready ones offer immediate possession and established amenities, but maybe less future appreciation. Yamuna Expressway projects, with Jewar Airport coming, promise high ROI by 2026. But under-construction mein delays ka risk hai, and OC milne tak ka wait. Which area do you think will give maximum appreciation over the next 2-3 years, considering current trends and infra development? Kya Sector 150 already overvalued ho gaya hai?
