Why Choose a 15-Year Mortgage?
Build wealth faster with dramatic interest savings and rapid equity growth
Save Massive Amounts on Interest
Pay 50-60% less in total interest over the life of the loan. On a $500k loan, that's $200,000+ in savings.
Own Your Home in Half the Time
Be mortgage-free in 15 years instead of 30. Retire debt-free or use savings for other goals.
Build Equity Twice as Fast
More of each payment goes to principal from day one. Achieve 50% equity in just 7-8 years.
Lower Interest Rates
Typically 0.25-0.5% lower rate than 30-year mortgages, saving even more money.
Why Choose a 30-Year Mortgage?

Lower Monthly Payments
More affordable monthly payments free up cash for other expenses, investments, or savings.
Greater Payment Flexibility
Pay the minimum when needed, or make extra payments when possible. You control the pace.
Easier to Qualify
Lower monthly payment means lower debt-to-income ratio, making approval easier.
Preserve Liquidity
Keep more cash available for emergencies, investments, or opportunities.

Frequently Asked Questions
Get answers to common questions about choosing your mortgage term
How much can I save with a 15-year mortgage?
On a $500,000 loan at 6.5%, a 15-year mortgage saves approximately $240,000 in total interest compared to a 30-year mortgage at 7.0%. However, your monthly payment will be about $650-750 higher with the 15-year term.
Should I choose a 15-year mortgage if I can afford it?
Not necessarily. Even if you can afford the higher payment, consider: (1) Do you have 6+ months emergency savings? (2) Are you maximizing retirement contributions? (3) Do you have high-interest debt to pay off? (4) Would you benefit from investing the payment difference? A 30-year mortgage with voluntary extra payments often provides the best of both worlds.
Can I pay off a 30-year mortgage in 15 years?
Yes! You can make extra principal payments on a 30-year mortgage to pay it off faster. This gives you flexibility: make extra payments when you can, but fall back to the lower required payment if needed. However, you'll pay a slightly higher interest rate (0.25-0.5%) compared to a 15-year mortgage.
Which mortgage term is better for first-time buyers?
Most first-time buyers choose 30-year mortgages for the lower monthly payment and easier qualification. This provides financial flexibility while establishing homeownership. You can always refinance to a 15-year term later or make extra payments as your income grows.
How does the interest rate difference affect my decision?
15-year mortgages typically have rates 0.25-0.5% lower than 30-year mortgages. Combined with the shorter term, this compounds your savings. However, the higher monthly payment is the main factor to consider for your budget.
What if I want to build equity fast but need flexibility?
Consider a 30-year mortgage and voluntarily make extra principal payments. You get the flexibility of lower required payments if finances tighten, plus the ability to build equity faster when possible. Just ensure your loan has no prepayment penalty.
Are there other mortgage term options besides 15 and 30 years?
Yes! Many lenders offer 20-year and 25-year mortgages as middle-ground options. These provide moderately higher payments than 30-year loans but significant interest savings compared to the full 30-year term. Ask us about custom term options.
Which term is better for investment properties?
Investment property buyers often prefer 30-year mortgages to maximize cash flow and keep more money available for additional investments or property improvements. The tax-deductible interest can also be beneficial for investment properties.
