It’s a good question: loans come with interest, so you always have to pay back more than you borrowed. How is borrowing possibly a good idea?

Say you want to buy a house. Houses aren’t cheap, but they’re generally necessary (unless you want to live in your car). Especially if you’re fairly young and just starting out, chances are you probably can’t afford to just drop the full value of that house, in cash, up front, into the seller’s lap. But if you take out a mortgage to pay for the house, you can pay it back a little at a time. True, you’ll end up paying back more over time than if you’d just paid up front, but presumably you’ll be making more money as your life progresses, and then mortgage payments will count for less of your budget.
