New Delhi flats: Hidden costs aur possession risk?

Honestly, I thought buying a flat would be simpler, but the hidden costs are crazy. Just moved into Apex River View last month, and the ₹2.63 Cr price tag was just the start. Stamp duty, registration, then interiors... total kharcha bahut zyada ho gaya. Meri friend Swaraj Homes Sukhdev Vihar dekh rahi hai, usmein toh possession ka bhi risk hai. Ready-to-move ka peace of mind sahi hai, but under-construction mein kya total cost ownership mein savings hoti hain? Yaar, Swaraj Homes ka actual status aur extra costs koi bata sakta hai?
