My high-stakes Gurgaon investment dilemma

Did a quick walkthrough of DLF Camellias last Sunday. Price points are insane, but for an investor, kitna capital appreciation possible hai ab? Ultra-luxury mein resale market thoda limited rehta hai, from my experience. What's the realistic rental yield on these units? Main concern exit strategy hai. Who's the target buyer in 5-7 years? Any tips on assessing this?
