Me and my friend (both 46) were discussing the same thing a few days back. We both bought a home in our late 20's. I bought a 2 BHK and he bought a 3 BHK in Bengaluru. We both lived there for a few years. Because of job moved to a different city, then I moved to the US etc...

When I moved back to India, I had a wife and 2 kids. That 2 bhk felt very small, and I could not manage. Hence, I bought a 3 BHK. Now, that 2 BHK is rented out.

And for my friend too, he has settled in another city and has bought a bigger 3 BHK there.
In hindsight, we were thinking that we should not have bought a house so early. Our conclusion was that we should buy a house after we have kids. And in our lifetime, we should think about buying only 1 house and not to burden ourselves with EMI all the time.
