New 3BHK in Mohali, now second-guessing timing

Honestly, I thought moving into our new place in Mohali would be the end of the real estate stress. We got a 3BHK from S S Developers Mohali near Sector 82, possession was in March. Sab sahi lag raha tha initially, but now I'm seeing things. Log bolte hain Mohali ka future bright hai, especially with IT City nearby. Par kya real mein infrastructure projects se prices utne badh jaate hain? Our area Prem Nagar, it's okay, connectivity theek hai. But I'm wondering if I should've waited for something closer to Aerocity. What's the scene with appreciation in these slightly older sectors versus the newer, more 'developed' ones? Any first-hand experiences?
