Let's say you're a poor minority and you want to buy a house. You've looked but even the most modest homes are too expensive. Nevertheless you really want to own something so you hire a realtor and you find a home that you love but don't think you can afford.
"Don't worry," says the realtor, "I know someone who can help."
"But my credit's not all that good either" you say.
The realtor beams. "No problem. We can get you into an ARM"
"What's that?" you ask.
"Why it's an adjustable rate mortgage" the Realtor answers, "the starting rate is really quite affordable, even on your salary."
"But what about when it goes up" you ask.
"Don't worry!" the realtor says, "you can re-fi and even if you can't your salary will probably will go up! You can't lose.
The realtor works a deal with their mortgage broker. The realtor makes a commision. The broker makes money too and the lender sells the loan. Meanwhile your employer says that raises are out of the question and that cut backs will have to be made. You're put on part time. You get a second job but even with that you're barely scraping by and then the mortgage rate goes up...
Yes, it's all your fault, right?
