Buying Homes is becoming tough these days

I was having conversations with my friends, on this he is paying 33K as an EMI, and paying rent for 50K for his flat in different city, so investing into new projects becomes difficult for people like him. But that 33K is still coming back from rent, so that's not a big deal but buying a flat requires alot of headspace and investment. With Job Market not stable people are scared to buy homes without because EMI becomes a headache for them.

I felt I should help others understand investing smart becomes important today. I am also learning day by day how market works, when you should buy? What things you should look into this before buying.

Well I want to saying buying a big flat takes a lot I am happy to learn about others how do they think before buying?
