What Is a Mortgage?
A mortgage is a loan used to purchase or maintain a home, land, or other types of real estate. The borrower agrees to pay the lender over time, typically in a series of regular payments that are divided into principal and interest. The property serves as collateral to secure the loan.
How Mortgage Payments Work
Most mortgage payments consist of four components, often referred to as PITI:
- Principal: The original amount of money borrowed to buy the home.
- Interest: The cost of borrowing the principal, expressed as a percentage rate.
- Taxes: Property taxes assessed by local government, usually held in escrow by the lender and paid on your behalf.
- Insurance: Homeowners insurance protects against damage to your home, also typically held in escrow and paid by the lender.
Additionally, some mortgage payments include Private Mortgage Insurance (PMI) if your down payment is less than 20% of the home's purchase price, as well as homeowners association (HOA) fees if applicable.
Types of Mortgages
Fixed-Rate Mortgages
With a fixed-rate mortgage, the interest rate remains the same for the entire term of the loan, which means your monthly principal and interest payment stays the same as well. This type of mortgage provides stability and predictability, making budgeting easier.
Common terms for fixed-rate mortgages are:
- 30-year fixed: Lower monthly payments but higher overall interest costs.
- 15-year fixed: Higher monthly payments but lower overall interest costs.
- 20-year fixed: A middle ground between 15 and 30-year terms.
- 10-year fixed: Highest monthly payments but lowest overall interest costs.
Adjustable-Rate Mortgages (ARMs)
An adjustable-rate mortgage (ARM) features an interest rate that changes periodically based on market conditions. Typically, an ARM starts with a fixed interest rate for a specified period (often 3, 5, 7, or 10 years), after which the rate adjusts at predetermined intervals.
ARMs are usually described in terms that indicate the initial fixed period and the frequency of rate adjustments, such as:
- 5/1 ARM: Fixed rate for 5 years, then adjusts annually.
- 7/1 ARM: Fixed rate for 7 years, then adjusts annually.
- 10/1 ARM: Fixed rate for 10 years, then adjusts annually.
Factors Affecting Your Mortgage Payment
Down Payment
Your down payment is the initial up-front payment you make toward the purchase of your home. A larger down payment reduces your loan amount, which can lower your monthly payments and potentially eliminate the need for PMI. The standard down payment is 20% of the home price, but many loan programs allow for smaller down payments.
Interest Rate
The interest rate on your mortgage significantly impacts your monthly payment. Even a small difference in rate can result in thousands of dollars saved or spent over the life of the loan. Interest rates are influenced by factors including:
- Current market conditions and the economy
- Your credit score and history
- Your debt-to-income ratio
- The loan term (shorter terms typically have lower rates)
- The loan type (conventional, FHA, VA, etc.)
Loan Term
The loan term is the length of time you have to repay the mortgage. Longer terms result in lower monthly payments but higher total interest costs over the life of the loan. Shorter terms have higher monthly payments but save on interest and allow you to build equity faster.
Property Taxes
Property taxes vary by location and are typically assessed as a percentage of your home's value. These taxes fund local services such as schools, roads, and emergency services. Property tax rates can change over time based on local budget needs and property reassessments.
Homeowners Insurance
Homeowners insurance protects your home and possessions against damage and theft. Mortgage lenders require borrowers to maintain adequate insurance coverage on the mortgaged property. Insurance costs vary based on:
- Location and risk factors (flood zones, wildfire areas, etc.)
- Home value and replacement cost
- Coverage limits and deductibles
- Claims history
Private Mortgage Insurance (PMI)
PMI is typically required if your down payment is less than 20% of the home's purchase price. It protects the lender if you default on the loan. PMI usually costs between 0.3% to 1.5% of your loan amount annually. Once you reach 22% equity in your home (based on the original purchase price), PMI is automatically terminated for most conventional loans.
Amortization: How Your Mortgage Balance Decreases Over Time
Mortgage amortization refers to the process of paying off your loan through regular payments. Each payment is split between principal and interest, with the exact proportion changing over time.
In the early years of your mortgage, a larger portion of each payment goes toward interest rather than principal. As you continue making payments, the amount applied to principal gradually increases while the interest portion decreases. This happens because interest is calculated based on the remaining loan balance, which decreases over time as you pay down the principal.
An amortization schedule (like the one provided by our calculator) shows exactly how each payment is split between principal and interest, as well as how the loan balance decreases over time.
Tips for Reducing Your Mortgage Costs
Make a Larger Down Payment
A larger down payment reduces your loan amount and can eliminate PMI, resulting in lower monthly payments and less interest paid over the life of the loan.
Improve Your Credit Score
A higher credit score can qualify you for lower interest rates. Before applying for a mortgage, take steps to improve your credit score by paying down debts, correcting errors on your credit report, and maintaining a history of on-time payments.
Shop Around for the Best Rate
Different lenders offer different rates and terms. Don't settle for the first offer you receive. Research and compare rates from multiple lenders to find the best deal.
Consider a Shorter Loan Term
While a 30-year mortgage is the most common, a 15 or 20-year term can save you thousands in interest. If you can afford the higher monthly payments, a shorter term builds equity faster and results in substantial long-term savings.
Make Extra Payments
Making extra payments toward your principal can significantly reduce your loan term and total interest paid. Even small additional amounts, such as rounding up your payment or making one extra payment per year, can make a big difference over time.
Refinance When Rates Drop
If interest rates drop significantly below your current rate, refinancing could lower your monthly payment and potentially save you money over the life of the loan. However, be sure to calculate the break-even point considering closing costs.
