What is the difference between “good debt” vs. “bad debt”?
From what I've heard in the past, debt can be differentiated between secured debt and unsecured debt.   Secured debt is a debt for which something stands good such as a mortgage on your house.  You have a debt, but that debt is covered by the value of an asset and if you needed to free yourself of the debt, then you could by selling that asset.   This is what is known as "good" debt.   Unsecured debt is debt that is incurred where the only thing that is available to pay it back is your income.  An example of this is credit card debt where you purchase something that couldn't be sold again to pay off the debt.   This is know as "bad" debt. You have to be careful about thinking that house debt is always "good" debt because the house stands good for it though.  The problem with that is that the house could go down in value and then suddenly your "good" debt is "bad" debt (or no longer secured).  Cars are very risky this way because they go down in value.  It is really easy to get a car loan where before long you are upside down.    This is the problem with the term "good" debt. The label makes it sound like it is a good idea to have that debt, and the risk associated with having the debt is trivialized and allows yourself to feel good about your financial plan.  Perhaps this is why so many houses are in foreclosure right now, people believed the "good" debt myth and thought that it was ok to borrow MORE than the home was worth to get into a house.  Thus they turned a secured debt into an unsecured debt and put their residence at risk by levels of debt they couldn't afford. Other advice I've heard and tend to agree with, is that you should only borrow for a house, an education and maybe a car (danger on that last one), being careful to buy a modest house, car etc that is well within your means to repay.   So if you do have to borrow for a car, go for basic transportation instead of the $40,000 BMW.  Keep you house payment less than 1/4th of your take home pay. Pay off the school loans as quickly as possible. Regardless of the label, "good" "bad" "unsecured" "secured", I think that less debt is better than more debt.   There is definitely such a thing as too much "good" debt!
