I'm retired. Due to various circumstances I still have a mortgage, but my income covers all my living expenses including the house. So yes. If I didn't have the house I would still have living expenses. And for me the house means low-cost entertainment, since I garden, can go cross-country skiing out my door if the weather cooperates, have lots of space for my relatively low-cost hobbies, etc. If I were in an apartment I might save on rent, but I can certainly see other costs could go up.
