Kasturi Balmoral Estate: Real rental yield and exit strategy?

Been renting for ages, and honestly, I'm fed up. Finally taking the plunge, but confused about high-end projects like Kasturi The Balmoral Estate. Price tag is ₹6.6 Cr+ for a completed project. Investor perspective se, iska capital appreciation forecast kya hai? Matlab, future mein kitna upar ja sakta hai? Also, real rental yield kitna expect kar sakte hain from such a premium property in Pune? And is the resale market liquid enough for properties in this bracket? Thinking about long-term wealth creation, but exit strategy bhi important hai. Any experiences with such expensive properties?
