Refinancing your mortgage can save you hundreds of dollars per month — but it’s not always the right move. Here’s how to know when it makes sense for you.
The Break-Even Point
When you refinance, you pay closing costs (typically 2–3% of your loan amount). The break-even point is how many months it takes for your monthly savings to offset those costs.
Formula: Closing costs ÷ Monthly savings = Break-even months
Example: If closing costs are $8,000 and you save $320/month, your break-even is 25 months. If you plan to stay in the home longer than that, refinancing makes sense.
The Rate Delta Rule
A commonly cited rule of thumb: refinance when you can lower your rate by at least 1%. This is outdated advice.
A better rule: refinance when the break-even point is under 36 months and you plan to stay in the home.
For Orange County homeowners with $600K+ loan balances, even a 0.5% rate drop can generate meaningful savings — often $250–400/month.
3 Scenarios Where Refinancing Almost Always Makes Sense
1. Your Rate Is 0.75%+ Above Market
If you locked in a rate during a high-rate period (2022–2023), you may be sitting on a rate of 7.5% or higher. With current rates in the 6.5–6.75% range, a rate-and-term refinance can deliver immediate monthly savings with a break-even under 24 months.
2. You Want to Eliminate PMI
If you originally put less than 20% down, you’re likely paying Private Mortgage Insurance (PMI). Once your home has appreciated to give you 20%+ equity, a refinance can eliminate PMI — potentially saving $200–400/month on its own.
3. You’re Converting From ARM to Fixed
If you have an adjustable-rate mortgage (ARM) that’s approaching its adjustment period, locking into a fixed rate now provides certainty and can prevent payment shock.
When NOT to Refinance
- You’re moving within 2 years. If you won’t reach break-even before selling, refinancing is rarely worth it.
- Your credit has dropped significantly. A lower credit score means a higher rate, which reduces your savings.
- You’re far into your loan. Refinancing resets your amortization, meaning you pay more interest in early years again.
What We Look At
When a client comes to me about refinancing, I look at:
- Current rate vs. market rate — the delta tells me the raw potential savings
- Remaining balance — higher balances amplify both savings and closing costs
- Equity position — determines loan-to-value and available loan programs
- Credit score — the biggest driver of what rate you actually qualify for
- How long you plan to stay — determines if break-even is achievable
If refinancing makes sense for your situation, I shop 20+ lenders to find the lowest rate available. If it doesn’t make sense right now, I’ll tell you that too — and we can set a trigger rate that would make it worth revisiting.
