My Saini Bhawan possession saga: What I wish I knew

Okay I'll be honest — I'm currently in a 2BHK in Sector 22, thinking of upgrading to a 3BHK or maybe a villa. Saini Bhawan was on my radar, but the possession experience has me worried. Friends told me about significant possession delays, like 1.5-2 years beyond the promised date. Is this normal for Chandigarh builders? Also, what about hidden charges at the very end? Did you face unexpected PLC or maintenance deposit demands? Really not sure if the price jump for a 3BHK is worth this uncertainty. Any insights on their defect liability period after possession?
