I recently got an approval and went through a similar process. My hitch was that I had to show enough income to pay for my current house and the new house. I could not count any rental income, which to me seems a bit ridiculous in some ways.
Back in late 2002 I went through a similar rigorous process to get my mortgage through Wells Fargo on my current house; which is why I had no idea that at the same time basically anyone could get a mortgage. Yes, I got burned.
