For many people, purchasing a home is one of the largest financial decisions they will ever make. Because home prices often exceed what buyers can pay upfront, mortgages make homeownership possible by allowing individuals to finance the purchase over time. Understanding how mortgages work helps buyers make informed decisions, compare loan options, and confidently prepare for one of life’s most significant investments.
A mortgage is a loan provided by a financial institution that allows a buyer to purchase real estate. The borrower agrees to repay the loan through scheduled monthly payments over a predetermined period, commonly 15, 20, or 30 years. Until the mortgage is fully repaid, the lender maintains a legal interest in the property, which serves as collateral for the loan.
Most mortgage payments consist of four primary components often referred to as PITI: principal, interest, taxes, and insurance. Principal represents the amount borrowed that is gradually paid down over time.
Interest is the cost of borrowing money from the lender. Property taxes are typically collected through monthly payments and forwarded to local governments, while homeowners insurance helps protect the property against covered losses. Some buyers may also be required to pay private mortgage insurance (PMI) depending on their down payment and loan type.
