Ujjwal Apartment appreciation claims overhyped lagte hain?

Loan pre-approved, now seriously looking at Ujjwal Apartment in New Delhi for investment. Builder ke appreciation claims toh bahut high hain, but from my experience, real capital appreciation forecast kya hai yahan? Rental yield kitna mil sakta hai, anyone living nearby? And resale market mein liquidity kaisi hai, will it be easy to exit in 5-7 years? Bahut important hai for calculated risk.
