You are interested in buying a house that costs $300,000. You plan to make a 20% down payment and borrow 80% of the purchase price. You will issue a mortgage loan (yes, the borrower is the issuer of the mortgage loan) to the bank who is lending you the money. The term of the mortgage loan is 15 years.
