Fed up of renting, finally taking the plunge

Spent the whole Sunday checking out options in Investment Hotspots, Greater Noida. Honestly, fed up of renting now; landlord raised rent again, so this EMI vs rent math is finally making sense. I'm looking at a 2BHK there, around ₹78L, mostly under-construction projects. But yaar, Investment Hotspots mein kya-kya hidden risks hain jo dekhne chahiye? Builder ka track record toh check kar raha hoon, but actual ground reality kya hai? Kya amenities jo brochure mein bolte hain, woh milte hain ya sirf photos mein achhe lagte hain? Maintenance cost ka koi hidden catch hota hai kya? Resale value ka bhi tension hai after a few years, not sure if it's a good long-term bet. Has anyone faced unexpected issues or red flags after buying in this area? Any advice for a first-time buyer like me?
