I remember one time when my dad had to take a house mortgage, and the years it took to paying them off. We weren't really broke, but since my father isn't really the extravagant type (he loves wearing his old shirts and pants wherever he went, to the dismay of my mother! lol), he didn't have a hard time paying them off.
Mortgages is a sensitive topic for some, specially those who are in more of a debt because of it. But I believe that if you really are disciplined enough to pay it off, then you can! Just like my dad. :)
