Also, you're talking about a mortgage for a property worth over $400k. It's unreasonable to expect that unemployment would be enough to pay everyone's mortgage, regardless of how much it is.
But Portland is pretty affordable. $400k doesn't get you much in California (there are foreclosures in South Central listed for that much on Zillow right now).
Quick google search shows that the median income for the UK is £585 per week, which works out at around £30,420 a year (or $37,647.03 USD).
Hardly luxurious in the UK or US. Probably enough to get by, but nothing amazing.
Can't believe how out of touch with reality some of the people on here are. My post is sitting on -4 right now. 24KGBP per year, after tax, for being unemployed. You've got to be kidding me.
