MRG The Balcony owners: What's the investor reality?

Honestly not sure if I'm overthinking this whole upgrade thing. I'm currently in a 2BHK and looking at MRG The Balcony for a 3BHK investment. It's completed, which is good. My budget is around ₹80L. I'm trying to figure out the actual rental yield here. What kind of monthly rent can one realistically expect? Also, for a project like this, how's the resale market? Is it liquid enough to ensure a good exit strategy in 5-7 years? Don't want to get stuck.
