That works both ways. Google "underwater mortgage"
In a non-recourse state (or, to a lesser extent, even in a recourse state) foreclosure on an underwater mortgage loans isn't a great deal for the bank; it either eliminates any chance on recovering part of the mortgage (non-recourse), or turns the amount above what can be realized in a foreclosure sale into a non-secured debt (recourse). Depending on circumstances, there's a chance they'll just choose not to do that for a very long time (much longer than would be the case either with an "above water" mortgage that wasn't being paid, or than a landlord would float a tenant that wasn't paying.) They also have a pretty big incentive to approve a short sale on an underwater mortgage, since you'll probably get a better price than a foreclosure sale and cost them less money than foreclosing and trying to sell.
(Have I been underwater, gone an extended period of time withput paying a mortgage both while living in the home and then after moving out, getting a buyer, and proposing and waiting for approval for a short sale, in a non-recourse state? Yes, yes I have.)
what matters is that someone can take away your property if you don't do what they say. That's not ownership.
People lose their house often to runaway property taxes.
This should anger people more.
If purchasing a piece of land means that it stays within your family forever with no additional payments or taxes, that's feudalism.
feudalism is NOT owning your land because the government owns it and you pay them for the use of the land which is exactly what we have now.
Even feudal lords had to protect their own land and were also expected to protect their serfs, lest their serfs' foods be given to raiders rather than their lord.
If you own your home outright, and then take out a HELOC, do you no longer own your home?
