Understanding Your Mortgage
A mortgage is a loan used to purchase real estate, where the property serves as collateral. In the US, most homebuyers use mortgages to finance their home purchases, with the most common options being 30-year and 15-year fixed-rate loans.
Key Mortgage Components
- Loan Amount: The total amount borrowed to purchase the home (purchase price minus down payment).
- Down Payment: Your initial payment, typically 3-20% of the home price. Larger down payments reduce your loan amount and may eliminate PMI.
- Interest Rate: The cost of borrowing money, expressed as a percentage. Rates vary based on credit score, loan term, and market conditions.
- Loan Term: The repayment period (usually 15 or 30 years). Shorter terms have higher payments but lower total interest costs.
Additional Homeownership Costs
Beyond your mortgage payment, budget for these recurring expenses:
- Property Taxes: Annual taxes assessed by local governments, typically 1-2% of home value.
- Home Insurance: Protects against damage to your property, usually $1,000-$2,000 annually.
- PMI: Private Mortgage Insurance (required if down payment < 20%) that protects the lender.
- HOA Fees: Monthly fees for community maintenance (common in condos and planned communities).
- Maintenance: Budget 1-2% of home value annually for repairs and upkeep.
Mortgage Tips
- Improve your credit score before applying to qualify for better rates
- Compare loan offers from multiple lenders
- Consider making extra payments to reduce interest costs
- Refinance when rates drop significantly below your current rate
- Factor in all homeownership costs when determining affordability

Key Mortgage Terms Explained
Loan Amount
The total amount you're borrowing to purchase the home, calculated as the purchase price minus your down payment. Most lenders require your total monthly debts (including the new mortgage) to be below 43% of your gross income.
Down Payment
Your initial cash investment in the property. While 20% down payments eliminate PMI requirements, many loan programs allow as little as 3-5% down for qualified buyers.
Interest Rate
The annual cost of borrowing expressed as a percentage. Rates vary based on credit score, loan term, and market conditions. Even a 0.5% rate difference can save thousands over the loan term.
Loan Term
The repayment period for your mortgage. Common terms are 15 and 30 years. Shorter terms have higher monthly payments but significantly lower total interest costs.
Understanding Your Payment Breakdown
A mortgage payment typically includes four components:
- Principal: Reduces your loan balance
- Interest: The cost of borrowing
- Taxes: Property taxes collected in escrow
- Insurance: Homeowners and possibly PMI
Additional Homeownership Costs
Beyond your mortgage payment, budget for these recurring expenses:
| Expense | Typical Cost |
|---|---|
| Property Taxes | 1-2% of home value annually |
| Home Insurance | $1,000-$2,000 per year |
| PMI (if <20% down) | 0.3-1.9% of loan amount annually |
| Maintenance | 1-2% of home value annually |
Mortgage Tips for Homebuyers
- Improve your credit score - Scores above 740 qualify for the best rates
- Compare multiple lenders - Rates and fees can vary significantly
- Consider points - Paying discount points can lower your rate
- Factor in all costs - Use our calculator to see the complete picture
- Make extra payments - Even small additional payments reduce total interest
Fixed vs. Adjustable Rate Mortgages
Our calculator focuses on fixed-rate mortgages (FRMs), where the interest rate remains constant. Adjustable-rate mortgages (ARMs) typically start with lower rates that change periodically after an initial fixed period (usually 5-10 years). While ARMs can save money short-term, FRMs provide payment stability over the full loan term.
Frequently Asked Questions
How much house can I afford?
Most lenders recommend keeping your housing costs below 28% of gross monthly income. Use our calculator to test different price points and see how they affect your monthly budget.
Should I put down 20%?
While 20% down eliminates PMI, many buyers opt for smaller down payments to preserve savings. The right amount depends on your financial situation and local market conditions.
How does refinancing work?
Refinancing replaces your current mortgage with a new loan, typically to secure a lower rate or change terms. Closing costs usually equal 2-5% of the loan amount.
