The look of contemptedness is meant to make you jealous so you want to buy the house and have what he has ! (this hapiness is unfortunately not tied to the hot tub, but now you can be in debt AND miserable in a hot tub)
I think you mean contentedness. You’re confusing content (being happy) with contempt (strong dislike or lack of respect). The sound fairly similar in English. I think it’s safe to say I’ll never own property, let alone one with a deck and hot tub! But I’m happy enough with a glass of wine in the bath 🛁
