If you're thinking about buying a home, you're almost certain to meet the word "mortgage"—but what is it, and how does it work? Today, we break down the basics: types of mortgages, the approval process, what drives loan costs, and how to navigate offers for the best deal.
A mortgage is a special kind of loan that helps you purchase or maintain real estate, with the property itself held as collateral by the lender. To get one, you'll apply to a bank, broker, or specialist lender, showing you can handle regular payments of principal and interest and meet credit, income, and down payment requirements. Most mortgages last for 15 or 30 years, though options range from five to 40 years. Miss payments, and you risk foreclosure—losing your home to the bank.
Types of Mortgages You'll See
Fixed-Rate Mortgages
The classic choice with a stable interest rate and consistent monthly payment throughout the entire loan term. Perfect for buyers who want predictability and protection from rate increases.
Best for: Budget-conscious buyers seeking stability
Adjustable-Rate Mortgages (ARM)
Starts with a lower initial rate that can adjust up or down with market conditions after a set period (typically 3, 5, 7, or 10 years). Offers lower initial payments but carries rate risk.
Best for: Short-term homeowners or rate forecasters
Interest-Only & Payment-Option Loans
Sophisticated loans allowing you to pay only interest initially, with large balloon payments due later. These come with significant risks and require careful financial planning.
Best for: Experienced investors only
Government-Backed Loans
FHA loans (low down payment), USDA loans (rural buyers), and VA loans (veterans) support those outside conventional qualification. Each has unique benefits and requirements.
Best for: First-time buyers, rural buyers, veterans
💡 Reverse Mortgages for Retirees
For homeowners 62 and older, reverse mortgages allow you to cash out home equity without selling. However, the loan comes due when you pass away, move permanently, or sell the home.
The Mortgage Approval Process
Financial Review
Lenders examine your credit score, assets, employment history, existing debts, and income to assess your ability to repay.
Pre-Approval
After verification, you receive a pre-approval letter showing how much you can borrow. This gives you credibility when making offers on homes.
Home Shopping & Offer
With pre-approval in hand, you can confidently shop for homes and make competitive offers knowing your financing is solid.
Final Approval & Closing
After your offer is accepted, the lender conducts a final appraisal and verification. You'll then head to the closing table to sign documents and officially own the property.
What Determines Your Mortgage Rate?
Market Conditions
Federal Reserve policy, inflation, and broader economic trends directly impact available rates. When the Fed raises rates, mortgage rates typically follow.
Your Credit Profile
Higher credit scores qualify for lower rates. A 750+ score can save you thousands compared to a 620 score over the life of your loan.
Loan Type & Term
15-year mortgages typically have lower rates than 30-year loans. Government-backed loans may have different rate structures than conventional loans.
Down Payment Size
Larger down payments (20%+) reduce lender risk and qualify you for better rates. Smaller down payments may require PMI, increasing your costs.
Average Mortgage Rates - September 2025
| Loan Type | Average Rate | APR |
|---|---|---|
| 30-Year Fixed | 6.30% | 6.45% |
| 15-Year Fixed | 5.49% | 5.68% |
| 5/1 ARM | 5.85% | 6.12% |
| FHA 30-Year | 5.95% | 6.18% |
⚠️ Rate History Note: Rates spiked to 7%+ in 2022–2023 before settling back. This volatility underscores why shopping around with multiple lenders is crucial.
Smart Tips for Mortgage Hunters
Compare Multiple Lenders
Don't settle for the first offer. Compare rates and terms from at least 3-5 lenders to find the best deal.
Use Online Calculators
Use mortgage calculators to estimate monthly payments based on different loan amounts, rates, and terms.
Understand PMI Costs
If you put down less than 20%, most lenders require private mortgage insurance (PMI). Plan to remove PMI once you reach 20% equity.
Explore Alternative Financing
If you need additional funds, junior mortgages or home equity loans may offer better terms.
