Rent vs Buy in Bangalore - What am I missing here?

I’ve been trying to break this down logically but something feels off in my conclusion.

Right now:

• Rent: ~₹60K/month
• Assuming ~7% yearly increase

Alternative:

• Buying ~₹2 Cr flat
• Or investing the difference at ~10% returns

When I roughly project this over time, renting + investing seems to come out ahead, which is confusing because most people still push buying as the better decision.

I tried putting numbers into a few calculators online (this is one of them):

But I’m not fully confident I’m interpreting things correctly.

Where I think I might be wrong:

• Maybe property appreciation assumptions?
• Maybe I’m underestimating hidden ownership costs?
• Or overestimating investment returns?

Would like someone who has actually gone through this decision to point out flaws in this thinking.
