My 'Ready to Move' ROI calculation reveals hidden costs

Budget finalised, loan pre-approved – now stuck on which sector. My kids' school admission is next year, so we urgently need a 3BHK in Noida Extension. I've been deep-diving into 'Ready to Move' properties, and honestly, I think many buyers miss factoring in long-term hidden costs beyond just EMI. My wife's priority is safety and good schools, so we’re looking at areas like Techzone 4 and Gaur City. But the 'Ready to Move' premium... is it still worth it, ya fir prices have already peaked? I'm trying to figure out if there's any real appreciation left or if it's just stable now. Any tips on calculating true ROI for end-use, considering maintenance, society charges, etc.? What specific projects or sectors do you guys think still offer genuine value and a good neighbourhood for children? Hope this helps someone else too.
