What is Mortgage Refinancing?
Refinancing means replacing your existing mortgage with a new loan, typically to secure a lower interest rate, change the loan term, or access home equity. But refinancing isn't free—closing costs typically range from 2-5% of the loan amount.
The 1% Rule of Thumb
Traditionally, refinancing made sense when you could reduce your rate by at least 1 percentage point. However, with lower closing costs available in 2026, even a 0.5% reduction can be worthwhile depending on your situation.
Break-Even Analysis
Calculate your break-even point:
Break-even months = Total closing costs ÷ Monthly savings
Example:
If you plan to stay in the home more than 31 months, refinancing makes financial sense.
Good Reasons to Refinance
1. Lower interest rate: Most common reason; reduces monthly payment and total interest paid
2. Shorten loan term: Refinance 30-year to 15-year mortgage to build equity faster and save on total interest
3. Remove PMI: Once you have 20% equity, refinance to eliminate private mortgage insurance
4. Switch from ARM to fixed: Lock in predictable payments if you have an adjustable-rate mortgage
5. Cash-out refinance: Access home equity for home improvements, debt consolidation, or investments (use cautiously)
When NOT to Refinance
2026 Market Context
With mortgage rates stabilizing around 6-7%, homeowners who locked in 3-4% rates during 2020-2021 should generally avoid refinancing. However, those with 7%+ rates from 2023-2024 may find opportunities as rates gradually decline.
