Dubai se Bangalore investment: Payment plan pe confusion

₹1.5 crore for a 3BHK in Prestige's Doddanekkundi project – that's what I was quoted. I'm based in Dubai, so can't do site visits often. Builder is pushing a construction-linked payment plan. Is it actually better for an investor like me than a fixed down payment? Kya hidden catches hote hain, especially when I'm not physically there to check progress? Power of attorney se sab smooth ho jayega kya, ya fir fixed down payment option better hai for peace of mind and less hassle? Rental income potential ke liye, possession jaldi milna important hai. What are people's experiences with these plans for properties in Whitefield or Sarjapur Road? Koi specific builders, like Prestige, ka payment plan experience share kar sakta hai?
