It’s one of the most common questions I hear from Washington homeowners: “Should I refinance now, or wait for rates to drop more?”
The honest answer is that it depends — on your current rate, your goals, how long you plan to stay in the home, and what you’d do with the savings. This post walks you through the framework I use with clients to make that call with confidence.
Start With Your Goal
Before running any numbers, get clear on why you want to refinance. The math looks different depending on your answer.
- Lower your monthly payment — the most common reason, and the easiest to calculate
- Shorten your loan term — pay off faster and save on total interest, even if your payment stays similar
- Remove mortgage insurance (PMI) — if your home has appreciated and you’re at or below 80% LTV, this can save hundreds per month
- Access equity (cash-out) — consolidate debt, fund a renovation, or cover a major expense
- Switch loan type — move from an adjustable rate to a fixed, or from FHA to conventional to eliminate mortgage insurance
Each of these has a different breakeven calculation and a different set of tradeoffs. Don’t let anyone tell you there’s a universal rule.
The Breakeven Calculation
For a straightforward rate-and-term refinance, the core question is: how long will it take to recoup the closing costs through your monthly savings?
The formula:
Total Closing Costs ÷ Monthly Payment Savings = Breakeven in Months
For example, if your closing costs are $6,000 and your new payment is $250/month lower, your breakeven is 24 months. If you plan to stay in the home longer than that, refinancing makes financial sense. If you’re likely to move or refinance again before then, it may not.
A few things that affect this calculation:
- Closing costs typically run 1–2% of the loan amount in Washington State, though this varies by lender and loan type
- No-closing-cost refinances shift those costs into a slightly higher rate — the breakeven disappears, but you pay more over time.
- Resetting your loan term matters: refinancing a 25-year-remaining loan back to 30 years lowers your payment but extends your payoff date and increases total interest paid
Another consideration may be reviewing the amortizations schedule to see how long it will take for you to return to your current mortgage balance.
NOTE: If you are refinancing to eliminate debt, the break-even calculation may not be as strong as a factor as what your total monthly savings will be, as well as the elimination of high-interest rate revolving debts.
When It Can Make Sense to Refinance Even Without a Big Rate Drop
Many homeowners assume refinancing only makes sense when rates have dropped significantly from their current rate. That’s not always true. Here are situations where refinancing can make sense even in a sideways or modestly lower rate environment:
PMI Removal
If your home has appreciated since you purchased it and your loan balance is now at or below 80% of the current value, a refinance can eliminate private mortgage insurance — even if your rate stays roughly the same. Saving $150–$300/month in PMI can have a very short breakeven even with modest closing costs.
Shortening Your Loan Term
If rates are even slightly lower than your current rate, refinancing from a 30-year to a 15- or 20-year loan can save tens of thousands in total interest. Your monthly payment may be similar or even higher, but the long-term math often works strongly in your favor.
Cash-Out for High-Interest Debt
If you’re carrying high-interest credit card or personal loan debt, a cash-out refinance at mortgage rates can meaningfully reduce your total monthly obligations — even if your mortgage rate goes up slightly. This requires careful analysis and isn’t right for everyone, but it’s worth modeling.
FHA to Conventional
FHA loans require mortgage insurance for the life of the loan (in most cases). If your home value has increased and you now have 20% or more equity, refinancing to a conventional loan eliminates that ongoing cost. This can be worth doing even if the rate difference is minimal.
ARM to Fixed
If you have an adjustable-rate mortgage and your fixed period is ending — or you’re concerned about future rate movement — locking into a fixed rate provides predictability that has real value beyond the monthly payment math.
When Waiting Makes Sense
Refinancing isn’t always the right move, even when rates drop. Here are situations where waiting or holding off may be smarter:
- You’re close to paying off your loan. In the later years of a mortgage, most of your payment is principal. Refinancing resets the amortization clock and front-loads interest again.
- Your breakeven is longer than your time horizon. If you’re planning to sell or move in the next two to three years, you may not recoup closing costs in time.
- Your credit or income situation has changed. A refinance requires full underwriting. If your credit score has dropped or your income is harder to document, it may be worth waiting until your profile is stronger.
- Rates are actively trending down. If there’s a clear downward trend and you’re not in a hurry, waiting a few months could meaningfully improve your terms — though timing the market is always uncertain.
The “1% Rule” — and Why It’s Oversimplified
You may have heard that you should only refinance if you can lower your rate by at least 1%. This is a rule of thumb, not a financial principle. It ignores your loan balance, your remaining term, your closing costs, and your goals.
A 0.5% rate drop on a $700,000 loan generates much more monthly savings than a 1% drop on a $200,000 loan. And if refinancing eliminates PMI or shortens your term, the rate difference matters even less.
Run the actual numbers — don’t rely on a rule of thumb to make a decision this significant.
What to Ask Before You Refinance
- What is my current rate, remaining term, and loan balance?
- What rate and terms can I qualify for today?
- What are the total closing costs — and can any be rolled in?
- What is my breakeven in months?
- How long do I plan to stay in this home?
- Does this refinance reset my loan term — and does that matter to me?
- Am I paying PMI, and would this eliminate it?
- Is there a no-closing-cost option, and how does it compare?
