Cashing out means getting a new loan on your home and borrowing some extra money. Let's say your home is worth $100,000, and you still owe $60,000 on your current mortgage. With a cash-out refinance, you can borrow 80% of your home's value, which is $80,000. This new loan will pay off your old mortgage of $60,000 and give you $20,000 in extra cash.
