If you bought a house out right for $ 100,000 and didn’t owe the seller anything, you would still lose that house if you did not pay your property tax. If you can have it taken away for not paying the government every year for it, then it is not yours. The government lets you stay that house for a fee.
Every state has a different law or use for it, but in every scenario you will lose your property if you don’t pay your fee for owning it every year.
Therefore nobody owns their home, you have the privilege of occupying it.
