Repaying your mortgage is a combination of interest payments and repaying the debt. It goes to zero eventually. A rent is a permanent payment into the account of the person renting you something they own.
The error to believe the house price will always continue to rise is a risky belief. People always need somewhere to live, but where and when you enter/exit the market matters. If mortgage interest rates were not set to keep the banks happy, then it would possibly be a realistic scenario to believe the housing market works for the benefit of the population.
This whole speculating on real estate value is more of an US thing than it is European. Outside of real estate investors, but those are the landlorda Germans, and others, rent from.
Many people do cash-out-refinances which ensures you never pay the house off, but if you just treat like the mortgage like rent and do nothing else (though if you can get a better interest rate refinancing for what you owe is often a good idea) you will pay it off. If you can afford the initial payment, your effective payment typically goes down over time as inflation brings the rest of your income up. Once you have the house half paid for odds are your payment is so low compared the income that you will have no problem paying the rest off. The early years are tough though before inflation works for you.
Of course if you do the cash-out refinance your payment raises more or less with inflation (just like rent) plus you get a nice chuck on cash to do whatever with. If you invest that cash wisely it might even be abetter investment than paying off the house (I don't think anyone has ever done this, but it is an option)
Ownership isn't and never is absolute possession.
I'm not going to go as far as the parent commenter to say it means you don't own it, but I can't think of any other possession where the government takes it away if you don't keep paying. Not books or washing machines or food or anything.
Even with vehicles, you need to pay to keep them registered but if you don't you just can't drive them on public roads. They're not taken away from you.
So real estate really is in a kind of special "you mostly own it but kinda not entirely".
Thing is so, tax debt or default doesn't lead to the state taking you property away (ultimately yes, but then you are at default for a vwry long time and probably bankcrupt anyway). It just means you have to repay you debt, tax authorities might seize e.g. bank accounts.
And even banks prefer refinancing over foreclosures, selling real estate is a risk and work German banks like to avoid.
It's not a tax on vehicle ownership, but rather on annual usage of public roads per vehicle.
Pets are one big category of stuff. Dangerous items are another.
> Ownership isn't and never is absolute possession.
Actually, it usually mostly is. There are exceptions, but generally speaking it is absolute possession. It's not conditional. It's called property rights for a reason. The fact that you're bringing up exceptions just proves the existence of the rule in the just place.
That doesn't mean you can use your property to do harm to others, or that you can bring it anywhere you want, or that it can't be seized if you refuse to pay debts. But most things you actually do simply own, flat-out, unlike real estate with its property tax requirement.
