Is J Block in Noida a calculated investment?

Is J Block in Noida still a calculated investment for appreciation? I'm assessing its potential, especially given the current market and Jewar Airport's impact. From my experience tracking Noida, prices are up 5-10% p.a. in many sectors. I'm looking at a 3BHK, maybe ₹1.8Cr to ₹2.2Cr. The data shows some growth, but I'm wondering if J Block's current pricing has already factored in major upcoming developments. What are the actual ground realities for ROI here over 3-5 years? Is there still negotiation room on these high prices, or are sellers holding firm? I've seen this pattern before where initial gains level off quickly once major news hits. Trying to avoid overpaying for future growth already priced in.
