Sector 35 flat hunt - school proximity is key!

₹1.5 crore budget, need at least a 3BHK near good schools in Noida. Kids' school admission is my biggest tension right now. Has anyone invested near Sector 35? My wife's priority is safety and a good neighborhood for the children. Honestly not sure if I should go for ready-to-move or under-construction. Sarthak Builder ke projects kaise hain? Heard mixed reviews. Kya kisi ko pata hai about rental yield reality in that area? Advertised yields seem too good to be true. Should I even consider Greater Noida instead? Matlab, is it worth the slightly lower price for the longer commute? I need some advice, friends!
