Why do people use mortgages, when they could just pay for the house in full?
Good question. If a person has a choice, it is probably better to pay cash. But not always. If your large pile of cash can earn more being invested than cost of the interest to borrow a similar large pile of cash, it is beneficial to get a mortgage. Otherwise pay cash. EXAMPLE: A house costs $100,000. I have $100,000 in extra money. I can invest that at 5% per year, and I can borrow an additional $100,000 at 2% per year. Since I can make more on my pile of cash than it costs to borrow another pile of cash, borrowing is better. Compound interest is the most powerful force on the planet according to Albert Einstein (maybe). That isn't likely for most people though. Here is the results from some online financial calculators. http://www.calcxml.com/do/hom03 Borrowing $100,000 with 2% interest for 30 years will cost a total of $148.662. You get $100,000, but it cost you $48,662 to do it. http://www.calcxml.com/do/sav07 Saving $100,000 in a bank account with an interest rate of %5 will be worth $432,194 in 30 years. By not spending the money you will earn $332,194 over the course of 30 years. So if you can invest at 5% and borrow at 2% you will end up with $283,532 more than if you didn't. It is a pretty extreme example, and financial advisers make a lot of money figuring out the complex nature of money to make situations like that possible.
