I don't know if any of you know regular people, but you all assume people in possible foreclosure are people with dumb loans...
My best friend with wife and 4 kids own a home in the northern ghetto of Milwaukee. They bought the house 9 years ago, with the housing "boom" their appraised value went up, and actually went up above their income level (meaning if they were to apply for a loan in the amount of their house they would not qualify). They refinanced 4 years ago to help with some debt, single working adult earning >$50,000 and got a decent rate for 4 years fixed rate.
Now with gas, utilities and cost of living raising 10x faster than raises, and he works in a business dependent on the new home market money is tighter than a nun's bum.
Market value has dropped on their appraisal, and currently they owe after 9 years just $3000 less than the value of the house. They never did a "dumb" loan, and have spent a bunch of money on the house in improvements. with that refinance 4 years ago I helped them completely finish the unfinished basement, including adding a 3/4 bathroom, and 3 rooms.
Situations like the above make up some part of the current housing problem, and you can't discount the housing "boom" 2+ years ago artificially inflating home values of those that already owned homes even in urban areas.
Personally I am disgusted with the home market, especially what I have seen in urban areas like my buddies. He has to deal with minorities walking into his driveway on fathers day afternoon and stealing his 5 and 7 year old's bikes with training wheel's still on them. He and I made the mistake of going to Home Depot for some plumbing accessories and left the wife and kids to watch the teenage minorities carry off the bikes, only to find 2 days later they bikes ruined and lying in a ditch. That was 2 years ago.
So his neighborhood has become a cesspool. It has happened in the same time frame as the housing "boom" but now he is S.O.L. He can't afford a home out of the city and they have to deal with it... and because of appraisers artificially inflating the value of his home, then killing that value in the last few months he is losing more equity than 9 years and thousands of dollars invested in improving his home instead of letting it go to pot.
I rent and wouldn't consider owning until this stables out.
