I don’t think there is anything wrong at all to be proud of purchasing your home if it’s something that you can comfortably afford.
Of course I think you will really feel proud once you own your home free and clear from the bank. Because until then it’s the bank’s house not yours.
I don’t buy real estate (or stuff in general) to display them or look at it and think “man I’m smart”. I do own several properties and I am proud that I own them. I don’t think there is anything at all wrong to be proud of something that you work very hard and save up to purchase.
I think most people don’t buy real estate to feel clever about. Most people buy real estate to either (a) live in and it’s a home to them; or (b) for cash flow via rentals.
