My first mortgage numbers were nearly identical... on a $32,000 income. I borrowed much of my 'downpayment' on an unsecured line of credit, because I was fresh out of grad school, with no savings, but at least no other debt. Super sketchy. The bank had enough sense even in those days (2005) to be a bit nervous, and my parents were good enough to co-sign (also nervous). But, I knew I could make it, and I did. It was ridiculously tight, though, even with my very frugal habits. I don't think many people could manage that kind of mortgage on an income like mine was, so I sure hope this woman earns more than I did!
FWIW, I got my income up to $55000 just two years later by switching jobs, and was able to get that whole mortgage (and LOC) paid off in 6 years by putting in a lot of DIY and making some very good real estate swaps when I moved cities. So, it's possible. Highly unlikely, though, so I think I have to agree that this article sets a pretty irresponsible precedent.
