What Is a Mortgage?

A mortgage is a long-term loan used to finance the purchase of real estate. It allows homebuyers to pay a portion upfront—known as a down payment—while borrowing the rest from a lender. The borrowed amount is repaid over time through monthly payments that typically include principal and interest. In the U.S., the 30-year fixed-rate mortgage is the most common type, offering predictable payments over time. You can learn more from this CFPB explainer on mortgages.

Key Components of a Mortgage

• Loan Amount: The total amount you borrow from a lender, minus your down payment.
• Down Payment: Typically 3% to 20% of the home price. Higher down payments can lower your interest rate and eliminate PMI.
• Loan Term: The duration of the loan—usually 15, 20, or 30 years.
• Interest Rate (APR): The annual cost of borrowing, expressed as a percentage.

Ongoing Homeownership Costs

Beyond your mortgage payment, homeowners are responsible for several ongoing expenses:

• Property Taxes: Typically about 1.1% of your home’s value annually, depending on location.
• Home Insurance: Protects your home and belongings from damage or theft.
• Private Mortgage Insurance (PMI): Required if your down payment is less than 20%.
• HOA Fees: Applies to homes in communities managed by a homeowners association.
• Maintenance: Annual upkeep typically costs 1% or more of the property value.

One-Time Costs to Keep in Mind

• Closing Costs: Fees paid at final purchase—usually 2–5% of the home’s price. For a full breakdown, visit NerdWallet’s guide to closing costs.
• Initial Renovations: Optional updates or repairs made before moving in.
• Furnishing & Moving: Includes furniture, appliances, and moving services.

Strategies for Early Mortgage Payoff

Paying off your mortgage early can save you money and offer peace of mind. Here are a few ways to do it:

• Make Extra Payments: Any additional payment goes toward the loan principal, reducing future interest.
• Biweekly Payments: Pay half your monthly payment every two weeks to make an extra payment each year.
• Refinance: Move to a shorter-term loan with a lower interest rate, if available.

Benefits:

• Save thousands in interest
• Achieve full ownership sooner
• Improved financial flexibility

Considerations:

• Possible prepayment penalties (check your loan terms)
• Reduced liquidity and tax deductions
• Less money available for investing elsewhere

A Brief Look at U.S. Mortgage History

Early in the 20th century, mortgages required large down payments and short-term loans. This model left many Americans unable to afford homes. After the Great Depression, the government created FHA and Fannie Mae to make homeownership more accessible.

These institutions introduced the 30-year fixed mortgage, fueling suburban growth post-WWII. Today, they continue to play a key role in stabilizing the housing market and supporting millions of homeowners.
