Here are my responses to your points.
- Stop paying your rent and see how long you stay in your place. Property taxes are included in the mortgage payment so I accounted for that in my payment.
- Please explain what you mean by "free loans." As someone who works in the industry, I can assure you there are no such thing as "free loans" anymore.
- There is at least something of value at the end of a mortgage.
- Yes there are maintenance costs associated with owning a home, but any smart landlord will add these costs into the rent of a home, therefore the renters are paying for this regardless. That's a cost you are already paying for something that isn't yours.
