Fed up with renting, eyeing Mohali's Sector 79

My lease ends in 3 months and I'm honestly fed up of renting. Landlord just hiked rent again, so finally taking the plunge to buy. I've been looking at Sector 79 in Mohali, specifically for a 3BHK. Prices seem to be around ₹1.7-2 Cr for something decent. Is this justified? Or are developers like Godrej or Emaar just pricing high? I'm wondering if there's any negotiation room or if these are sticker prices. What's the real resident life like there day-to-day? More importantly, what's the investment potential in 3-5 years? Should I expect good capital appreciation, especially with all the infrastructure talk around Mohali? Any insights on rental demand for a 3BHK in Sector 79 would be super helpful too.
