Frequently Asked Questions
Is refinancing from 30-year to 15-year worth it in 2026?
As of 2026, refinancing to a 15-year mortgage is worth it if you can afford the higher payment and plan to stay in your home beyond the break-even point (typically 2-5 years). With current rates 1% lower for 15-year loans, the savings can be substantial.
How much can I save by refinancing to a 15-year mortgage?
The savings depend on your current rate, new rate, and loan balance. On a $300k loan refinancing from 7.5% to 6.5%, you could save ~$150k in interest over 15 years.
What are the requirements to refinance to a 15-year mortgage in 2026?
As of 2026, you need good credit (typically 620+), sufficient income to support higher payments, and enough equity in your home (usually 20%+). Lenders also require stable employment history.
How long does it take to break even on refinancing?
The break-even period depends on closing costs and monthly savings. Typically, it takes 2-5 years to recoup closing costs. With $6k closing costs and $300/month savings, break-even is 20 months.
Should I refinance if I plan to move soon?
If you plan to move before the break-even point, refinancing may not be worth it. You should stay in the home long enough to recoup closing costs.
What credit score do I need to refinance to 15-year?
Most lenders require 620+ for conventional refinancing. Higher scores (740+) qualify for the best rates, potentially saving an additional 0.5% on your interest rate.
How much more will my payment increase?
On a $300k loan refinancing from 7.5% 30-year to 6.5% 15-year, monthly payment increases ~$800 (from ~$2,097 to ~$2,880).
Can I refinance to 15-year with PMI?
Yes, you can refinance even with PMI. If you have less than 20% equity, the new loan will also have PMI, but it may be lower due to the shorter term.
Is it better to refinance or make extra payments?
Refinancing gives you a lower interest rate permanently, but has closing costs. Extra payments are flexible but don't lower your rate. Compare the net savings after closing costs.
What if interest rates rise after I refinance?
If you refinance to a fixed-rate 15-year mortgage, your rate is locked in. You won't be affected by future rate increases.
