In the language of Rich Dad Poor Dad, your home is a liability and it doesn't matter whether you have a mortgage or not. Just because it's a liability doesn't mean that you shouldn't own it!! One could sleep on Mom's or a friend's couch. Or, one could buy an old camper and live in that. Forgive me by going a bit extreme to make a point.
It's useful to think about what in our lives is an asset and making us money versus that which is not. It helps bring clarity to the financial decisions that we make. At some point, we have to decide on a balance between our devotion to increasing our income and net worth versus pleasure and comfort in our lives. I have a lot more house than I really need and also own a newer car when an older one would do.
The key is living below your means. That is the formula that creates the extra cash flow needed to build an asset base. If your house is paid off, I expect that you already know this and are living this way. Congratulations!
14 years ago we bought our first multi-family property. About the same time our best friends bought a vacation house in Bend. Is a vacation home not offered for rent an asset? Well, our multi-family provided us monthly income - small at first but it grew over time. Our friend's vacation home cost them in extra utilities, property tax, insurance and upkeep. If one home is an asset then two is double the asset. In fact, they are both liabilities.
