Experion The Westerlies

Experion ka delivery track record toh accha hai, but The Westerlies mein capital appreciation expected se kam lag raha hai. I'm eyeing a unit around ₹12 Cr. Off the record, kya actual gains huye hain since launch? Aur in ₹8.99-18.04 Cr properties mein real rental yield kitna hai? High-end resale market kitna liquid hai? Meri exit strategy ke liye, will anyone buy from me in 5 years without a huge discount?
