Check the APR for Total Cost
When comparing mortgages, don't just look at the interest rate—consider the total cost over time. A key tip is to check the APR (Annual Percentage Rate), which includes interest plus fees.
Other costs to watch for include closing costs, lender fees, private mortgage insurance (PMI), and early repayment penalties. Also, consider how long you plan to stay in the home. A lower rate with high fees may not be the best deal if you sell in a few years. Comparing loan terms and asking for a loan estimate breakdown from lenders helps find the best option.
Understand All Mortgage Fees
Understanding the True Cost of a Mortgage
A low-interest rate sounds great, but it's not the only factor in the total cost of a mortgage. Fees, loan terms, insurance, and flexibility all play a role in what you'll actually pay. Here's what to consider before choosing a loan.
1. Loan Fees & Closing Costs
Lenders charge fees that can add thousands to your upfront costs. These include origination fees, discount points, processing fees, title & appraisal costs, and escrow prepayments. Some loans with low rates have high fees, so compare total costs.
Tip: Request a Loan Estimate from multiple lenders to compare fees.
2. Loan Term: 15 vs. 30 Years
Your loan term affects monthly payments and the total interest paid.
15-Year Loan: Higher payments but lower total interest.
30-Year Loan: Lower payments but more interest over time.
20-Year Loan: A balance between the two.
Tip: If you choose a 30-year loan but want to save on interest, make extra principal payments.
3. Mortgage Insurance Costs
If you put down less than 20%, you'll likely need mortgage insurance:
PMI (Private Mortgage Insurance): Required for conventional loans under 20% down.
MIP (Mortgage Insurance Premiums): Required for FHA loans.
VA & USDA Loans: No PMI, but funding fees may apply.
Tip: Conventional borrowers can remove PMI once they reach 20% equity. FHA loans typically require refinancing.
4. Prepayment Penalties & Loan Flexibility
Some loans charge a prepayment penalty if you pay off the mortgage early. Always check for: Extra payment restrictions, Fees for early payoff, Flexible payment options, like biweekly payments
Tip: Avoid loans with prepayment penalties if you plan to pay off your mortgage early.
5. Fixed vs. Adjustable-Rate Mortgages (ARMs)
Not all mortgages have fixed interest rates. Some adjust over time, which can lead to higher payments.
Fixed-Rate Mortgage (FRM): Predictable payments for the entire loan.
Adjustable-Rate Mortgage (ARM): Lower initial rate, but it can increase after the fixed period.
Tip: ARMs work best if you plan to sell or refinance before the rate adjusts.
6. APR: A Better Comparison Tool
Instead of just looking at the interest rate, check the Annual Percentage Rate (APR), which includes fees, points, and other costs. A low interest rate with a high APR may mean hidden expenses.
Tip: Compare both interest rates and APRs to find the most cost-effective loan.
Final Thoughts: Choose the Right Mortgage

Consider Loan Term and Costs
When evaluating the total cost of a mortgage, don't just focus on the interest rate; look at the APR (Annual Percentage Rate) instead. The APR includes both the interest rate and additional loan costs, such as origination fees, discount points, and mortgage insurance, giving you a more accurate picture of what you'll pay over time.
Some other factors that you should consider are:
- Loan Term: A 15-year loan may have higher monthly payments but lower interest compared to a 30-year
- Closing Costs: These can vary significantly between lenders and impact the upfront cost of your loan
- Prepayment Penalties: Some loans charge fees for paying off the mortgage early
- Escrow Payments: Property taxes and homeowners insurance can affect your monthly payments

Focus on Interest Accrual Methods
When looking at the total cost of a mortgage, I always recommend focusing on more than just the interest rate. One factor that often goes unnoticed is how interest accrues. Lenders typically use either the 30/360 method, which assumes 30-day months and a 360-day year, or the Actual/365 method, where interest accrues daily based on the actual number of days in a year. While the difference may seem minor, loans using the Actual/365 method can result in higher overall interest costs, especially on larger balances or longer terms.
Another detail to examine is how the loan amortizes. Two mortgages with the same interest rate can have very different long-term costs depending on how payments are structured. Some lenders allocate a larger portion of early payments toward interest rather than principal, which slows equity buildup and increases total interest paid. Reviewing an amortization schedule helps borrowers understand how their payments are applied over time.
Rate lock policies also play a role. Locking in a rate too soon can lead to unexpected extension fees if the closing is delayed. Some lenders offer float-down options, which allows borrowers to secure a lower rate if market conditions improve before closing—an easy way to save money without refinancing.

Look Beyond Interest Rates for Hidden Costs
When evaluating the total cost of a mortgage, I always look beyond just the interest rate because there are several hidden costs that can add up significantly. One key factor to consider is the annual percentage rate (APR), which includes not only the interest rate but also lender fees, discount points, and other charges. This gives a more accurate picture of the true borrowing cost.
I also advise borrowers to pay attention to closing costs, which can range from 2% to 5% of the loan amount. Property taxes, homeowners insurance, and private mortgage insurance (PMI) for lower down payments should also be factored in. Additionally, prepayment penalties or adjustable-rate loan structures can impact long-term affordability. When comparing loan options, I always calculate the total cost over the life of the loan, including monthly payments and fees, to ensure it aligns with financial goals.
