Then why would a bank give a loan, based on income, knowing that the income is not enough to be able to make the monthly payment?
I never said the bank is your parent.
Maybe the income-to-debt-ratio requirment should be changed?
I'm not sure why you are arguing with me. I think people know how much they can or cannot afford for a monthly payment. If they take on too much, then that is their own fault and they have to deal with it (although sometimes financial situations do change, but it's still the responsibility of the borrower).
Why? Why is it the banks job to decide what you can afford? There is no way without making someone put down everything they spent money on for the last few months (really good exercise to do for yourself and many who get into these messes may have theirs eyes opened but not really the banks business) and that would be really expensive for them to do. Probably not worth the extra cost over the rate of possible defaults (and the privacy concerns and everything else).
For example I spend WAY more on food then I need to. Because I like buying really yummy steaks to grill and then go out to eat often, etc. My parents pay way less for 2 people to eat. However my parents have a boat, camper, and two cars that take WAY more gas then the one car DH and I have.
If they figure out some type of "average" spending per adult and per child that would penalize those that live frugally so they can afford a dream house.
