I would think it a tax issue, but if you don't pay property tax in our area, people have the option to search the taxpayer rolls and pay unpaid taxes on property. They don't own the property. The property then goes up for auction by the county, and the person who paid off the taxes can bid on the interest rate. If that person cannot pay the taxes and interest (the original owner of the property), that person who paid the taxes can foreclose. This is why we always have the taxes set aside for our free-from-debt home. It is my understanding that should Trump be able to implement the change in finances (from Central Bank to gold standard), those taxes, which were illegally placed on us, making us also little corporations of tax hubs) will be eliminated. Until then, we must pay our taxes because life goes on via the deep state rules. My suggestion is to call your local property appraiser (tax assessor) in some areas and ask. And to clarify, I'm speaking from an American viewpoint. I forget we have folks from other countries on the board. I don't know how it works elsewhere and eve in different states and even counties, it may break down differently.
