That's a fair point as others have also pointed out. It's that I couldn't even imagine such a scenario. The society I live in, India, you will very rarely come across such a person, i.e., a single person with no dependents owning a house on mortgage. Once you start earning here there's almost someone financially dependent on you :). Could be your parents, spouse, children at various points in time.
