Frequently Asked Questions
Is a 15-year mortgage better than a 30-year?
A 15-year mortgage saves significantly on interest (often $200,000+) and builds equity faster, but requires higher monthly payments. It's better if you can afford the payments and want to be debt-free sooner. A 30-year offers lower payments and more flexibility.

On a $320,000 loan, a 15-year mortgage at 6.25% costs about $2,743/month vs $2,128/month for a 30-year at 7%, a difference of $615/month. The exact difference depends on loan amount and rates.
How much interest do you save with a 15-year mortgage?
On a $320,000 loan, you'd save approximately $272,000 in interest with a 15-year term vs 30-year. The savings come from both the shorter term and typically lower interest rate.
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 in 15 years. This gives you flexibility to reduce payments if needed, but requires discipline to consistently pay extra.
What credit score do I need for a 15-year mortgage?
For conventional 15-year mortgages: No blanket 620 minimum. Credit eligibility depends on automated underwriting findings, with final approval subject to lender review. A score of 740+ gets you the best rates. FHA 15-year loans may accept scores as low as 580.
Do 15-year mortgages have lower interest rates?
Yes, 15-year mortgages typically have interest rates 0.5-0.75% lower than 30-year mortgages because they're less risky for lenders due to the shorter repayment period.
Should I refinance from 30-year to 15-year?
Refinancing to a 15-year makes sense if you're 10+ years into your 30-year loan, can afford higher payments, and want to save on interest. Calculate if the interest savings outweigh closing costs.
What income do I need for a 15-year mortgage?
For a $320,000 loan ($2,743/month), you'd need roughly $98,000 annual income assuming a 43% debt-to-income ratio and no other debts. Lenders evaluate total debt, not just mortgage payment.

Yes, a 15-year mortgage can be smart if you're 10-15 years from retirement and want to enter retirement debt-free. Ensure you can afford payments without sacrificing retirement savings.
Can I switch from 15-year to 30-year mortgage?
Yes, you can refinance from a 15-year to 30-year mortgage if you need lower payments, but you'll pay more interest over time and extend your debt. This is typically done during financial hardship.
