Need help - should I buy a house or rent

My family already has a house although there is some debt left which I had inherited and to an extent reduced it, now it is negligible when it comes to Monthly cutting. The only concern is that it's old and is small given the family will become big slowly and I plan to get married by next year, I'm in this situation where people are saying put in efforts and buy a house but I have this feeling that we should rent for some years and then save to buy a property (all this, given property prices will keep on increasing) I have okay savings as of today, I have some in mf and stocks but that too is okayish. I need some of your opinions here. Gf will be studying for next 2-3 years, it's a constraint as well. Thanks 🙏🏽 Tc - 62 (16 var) Age - 27
