Sector 144 prices — my honest take after recent visits

Sector 144 prices feel a bit inflated for what's on offer, honestly. I'm currently in a 2BHK near Sector 137, thinking of upgrading to a 3BHK or even a small villa in Sector 144. Builders like Godrej or ATS yahan projects hain, but are these prices justified? Matlab, 3BHK ke liye ₹1.5 Cr+ seems a lot. What's the real ground reality for daily life there? Aur investment potential for 3-5 years? Will I get decent appreciation ya bas overpay kar raha hoon? Already have a home loan, so EMI will jump a lot. Any negotiation tips ya hidden costs jo log miss karte hain?
