Delhi owners: What's the real total cost of ownership?

What's the actual total cost of ownership for completed projects in Delhi? I'm so fed up of renting, landlord ne phir rent badha diya. Finally looking at Umang Winter Hills and Parsvnath La Tropicana. Both completed hain. Brochure prices never tell the full story. Registration, PLC, society charges... kitna extra lagta hai? Is Parsvnath ka higher entry point worth it for long-term appreciation, ya Umang Winter Hills better hai for ROI? Any actual owners here?
