I am young (only 22) so i have yet to worry about a morgage, and my understanding of them is probably not the best. This is my understanding of what has happened, maybe I can get some confirmation or correction:
Due to Clinton administration, the rules guiding the morgage lending system were not as tight as they had been previously. As a result of this as well as low interest rates, banks were able to offer exceptionally low interest morgages to almost anyone. The banks stipulated that the person only had to pay the interest per month minimum, but the principle did not have to be paid off. (i stress HAD to be, as in optional). The idea being that house values would increase over time. Example, Person buys house valued at 200,000. They only pay on the interest. In 7 years lets say, the house will be valued at 250,000. so if they walk away, they get 50,000 in pocket and everyone is happy. Some lenders began morgaging for the projected value of the house. Lending 300,000 on a house currently valued at 275,000 with a projected value of 325,000 in 10 years.
Congress then began raising interest rates. (something like 30 consecutive times in a row). so when people went to re-establish morgages the interest rates had increased substantially and the people could no longer afford the payments. If you owe 325,000 on a house worth 300,000 your gona walk away. and that's what happend.
So then you have the banks that need to sell these houses for something, so they sell low to cut losses, this drives the market down.
On top of that more and more people are defaulting.
Then the next problem comes with packaged morgages. Banks would sell morgages to other banks, in packages (so many billions of dollars worth or morgages at 4% or whatever). Many of these packages started containing more and more of these bad loans. So now you have a bunch of banks that are afraid to buy any of the other guys stuff for fear that it's all crap. (this isn't exclusive to american banks by the way). So the Government has steped in to say that they will be setting a base price for the morgages which gives a floor to the hole situation.
because the banks have to show their assets at market price, the 300,000 morgages were now on the books at lets say, 250,000 or maybe even 225,000. This so now the banks had less assets to borrow with, but still needed to hold whatever percent money for their depositors. As a result of the depreciated assets and not being able to borrow against them, they are not able to lend out, and now new loans and morgages become difficult to secure. which means no new money coming in from morgages...
seem right?..that's my understanding of it anyways.
so i say the government was at fault, they should clean it up. infact, in theory, by purchasing all these bad morgages, they could in THEORY make a profit if the housing market turns around.
