Maitri Apartments: My Delhi investment strategy confusion

Maitri Apartments mein actual capital appreciation kitni mili hai logon ko? My parents keep pushing for Delhi property but I'm honestly not sure about this one. Thinking of putting some money there for long-term investment. Kya yahan ka rental yield sahi hai, ya sirf paper pe accha lagta hai? I'm looking for a decent ROI. Also, resale market kitna liquid hai? Will it be easy to exit in 5-7 years if needed? Koi experience share kar sakta hai for Maitri?
