Parents pushing for buying a flat in Mumbai

Hi home owners in Mumbai. I wanted to get some views regarding this topic. I personally feel that spending 3-4 crore on a 3bhk flat in Mumbai subburbs makes no economic sense. My parents are very convinced that i should liquidate all my investments and they will also do the same to fund my future 3bhk flat. I am of the opinion that i can live on rent during the larger part of my life and only plan to buy if i feel financially secure in my late 40s. Right now my parents are looking at my frnds and cousins who have booked flats recnetly and feeling that i am missing out. Let me know your thought.
