Sitting on a 3.75 % note and asking whether to refinance 3.75% mortgage in Texas? We compare your current rate with today's 6 %-plus quotes, model break-evens, and show edge cases where a higher-rate refi still wins.
Is a Refi Worth It When Today's Texas Rate Tops 6 %?
With current 30-year rates at 6.19% nationally and Texas rates averaging 6.62%, your 3.75% mortgage looks increasingly valuable. The gap between your existing rate and today's market represents a significant cost difference that would increase your monthly payment substantially.
Fannie Mae's latest projections offer little hope for dramatic improvement. Their economic team forecasts rates ending 2025 at 6.4% - still well above your current rate. This persistent high-rate environment stems from ongoing inflation concerns and Federal Reserve policy adjustments.
For context, the spread between your 3.75% rate and today's Texas average represents nearly 3 percentage points - a gap that historically signals holding onto your existing mortgage rather than refinancing. The resources on rate dynamics can help you understand when refinancing typically makes financial sense.
3.75 % vs 6.1 %: Monthly Payment & Lifetime Interest Delta
The payment shock from refinancing at today's rates would be substantial. Moving from 3.75% to "The current average rate for a 30-year fixed mortgage is 6.19" increases your monthly payment significantly across all loan sizes. "Texas 30-year fixed mortgage rates go down to 6.62%," making the differential even more pronounced.
"The average cost of a mortgage refinance is $5,000, according to a 2022 report from Freddie Mac." These upfront costs must be recouped through monthly savings - impossible when moving to a higher rate.
The lifetime interest difference between a 3.75% and 6.1% rate on a 30-year loan is substantial. On a $300,000 mortgage, you would pay significantly more in interest over the life of the loan at the higher rate. This calculation alone typically eliminates refinancing from consideration unless you have specific circumstances requiring cash access or loan restructuring.
Why Waiting May Not Pay - Reading Fannie Mae's 2025-26 Outlook
Fannie Mae's economic forecasting team "We now project the 30-year mortgage rate to end 2025 and 2026 near 6.5 percent and 6.3 percent, respectively." Their May outlook was slightly more optimistic, "We forecast mortgage rates to end 2025 and 2026 at 6.1 percent and 5.8 percent, respectively," but even these lower projections remain well above your current rate.
The persistent elevation in rates reflects broader economic factors. Inflation expectations, Federal Reserve policy, and global economic conditions all contribute to keeping mortgage rates elevated. Fannie Mae predicts rates ending at 6.4% with only gradual improvement expected through 2026.
These forecasts suggest that waiting for rates to drop below your current 3.75% could take years - if it happens at all during this economic cycle. The opportunity cost of waiting includes continued exposure to potential rate increases and missing out on other financial opportunities that might require accessing home equity.

Five Loan Sizes Modeled: When Does a 6.1 % Refi Break Even?
Break-even analysis reveals the harsh reality of refinancing at higher rates. "Total loan costs / Monthly savings = Number of months it will take break even." - but with negative monthly savings, you'll never break even.
"Refinancing your mortgage typically costs between 2 and 6 percent of the new loan amount." "All in all, you can expect to pay around $5,000 to refinance your mortgage." When refinancing to a higher rate, these costs compound the financial disadvantage.
Consider these scenarios across different loan sizes:
$200,000 loan: Closing costs of 2-6% mean $4,000-$12,000 upfront
$300,000 loan: Expect to pay $6,000-$18,000 in fees
$400,000 loan: Costs could reach 3-6% or $12,000-$24,000
$500,000 loan: Total fees of $10,000-$30,000
$600,000 loan: "The average closing costs for a refinance mortgage in the U.S. totaled $2,403 last year, or about 0.72% of the loan amount, according to a new report from LodeStar Software Solutions." but can exceed $36,000
In each case, you're paying thousands upfront to increase your monthly payment - a losing proposition unless you have compelling non-rate reasons to refinance.
When a Higher-Rate Refi Still Adds Up
"Borrowers gave 'pay off other bills or debts' as the most common reason for cash-out refinancing." Despite the rate disadvantage, certain scenarios can justify refinancing even at today's elevated rates. Cash-out borrowers often use funds to consolidate high-interest debt, potentially improving their overall financial position despite the higher mortgage rate.
"Under the new rules, the FHA cash-out refinance loan-to-value ratio is lowered to 80%." This provides access to substantial equity for homeowners who've built significant value. If you're using funds for high-return investments or eliminating credit card debt at 20%+ interest, the math might work despite the rate increase.
"Private MI helped more than 800,000 HOUSEHOLDS purchase a home or refinance an existing mortgage in 2024, supporting nearly $300 billion in originations." PMI removal alone can save hundreds monthly for borrowers who've reached 20% equity since their original loan. This monthly savings could offset some or all of the payment increase from the higher rate.
Tap Equity to Consolidate Debt or Fund Upgrades
Cash-out refinancing makes sense when the alternative financing costs more. "Borrowers gave 'pay off other bills or debts' as the most common reason for cash-out refinancing." If you're carrying credit card balances at 18-24% interest, accessing home equity at 6.1% could save thousands annually despite the higher mortgage rate.
Shorten to 15 Years to Slash Lifetime Interest
Switching from a 30-year to a 15-year term dramatically reduces total interest paid. "The average 15-year fixed-mortgage rate is 5.50 percent," higher than your 3.75% but offering substantial long-term savings through the shortened term. Monthly payments increase, but you'll own your home outright in half the time.
Remove PMI Once You Reach 20 % Equity
"Private MI helped more than 800,000 HOUSEHOLDS purchase a home or refinance an existing mortgage in 2024, supporting nearly $300 billion in originations." If your home value has appreciated significantly since purchase, refinancing to remove PMI could offset the higher rate's impact on your monthly payment.

Key Takeaways Before You Call Your Broker
Your 3.75% mortgage represents a valuable asset in today's 6%+ rate environment. Unless you need cash for debt consolidation, can remove PMI, or want to shorten your loan term, refinancing will likely cost you money both upfront and monthly.
The numbers are clear: moving from 3.75% to 6.1% or higher increases your payment and lifetime interest substantially. Even with Fannie Mae's projections showing only modest rate improvements through 2026, waiting for rates to drop below your current level could take years.
For most borrowers with rates below 4%, the best strategy is simple: keep your existing mortgage. Monitor rates for any significant drops, but recognize that your low rate is worth protecting. If you do need to access equity, consider alternatives like a HELOC that preserve your primary mortgage rate.
Before making any refinancing decision, use the calculators and resources at Chestnut's refinancing guide to model your specific scenario. The right choice depends on your unique financial situation, but the math rarely favors giving up a 3.75% rate in today's market. When you do need mortgage expertise, Chestnut Mortgage offers AI-powered rate monitoring and fast pre-approvals to help you make the most informed decision.
Frequently Asked Questions
Is it smart to refinance a 3.75% fixed mortgage in Texas if 30-year rates stay above 6%?
For most borrowers, no. Moving to a higher rate raises the payment and lifetime interest, and you will not recoup typical closing costs. Fannie Mae projects rates in the mid 6s through 2025, so keeping the current loan usually wins unless you have a strategic reason.
When does a higher-rate refinance still make financial sense?
It can be justified for cash out debt consolidation, funding high return projects, removing PMI once you have 20% equity, or switching to a 15 year term to cut total interest. Run the numbers on your unsecured debt rates versus the new mortgage rate and include closing costs.
How do I calculate refinance break even and why is it negative here?
Break even equals total refinance costs divided by monthly savings. If the new rate is higher, savings are negative, so you never break even. Typical refinance costs range from roughly 2% to 6% of the loan amount, so paying those to accept a higher payment rarely pencils out.
What do current forecasts say about waiting for lower rates?
Fannie Mae expects the 30 year rate to finish 2025 around the mid 6% range with only gradual improvement in 2026. That suggests waiting for sub 3.75% could take years, so preserving a low existing rate and monitoring for tactical dips is prudent.
