Greater Noida 3BHK: Confused about market timing for family

Sector 150 — been researching this area for 6 months now. I'm looking for a 3BHK for my growing family; kids' school admissions are coming up. My wife's priority is safety and a good neighbourhood. Budget around ₹1.5 Cr. Honestly, main confused hoon ki is this the right time to buy. Jewar Airport aur Aqua Line Metro extensions kaafi buzz mein hain. Log bolte hain prices will only go up, but affordability ka kya hoga? Godrej Properties aur ATS ke projects dekhe hain, but unka price thoda high lag raha hai. Noida Extension mein thode better options hain, but connectivity ka kya scene hai? Should I wait a bit for prices to stabilize, ya abhi jump in kar loon? What's the real ground reality for families moving in now? Any advice on specific sectors for good schools nearby?
