If you're a homebuyer in Plano, Texas, the biggest question right now isn't whether to buy — it's when to lock your rate. Mortgage rates climbed back above 7% in September 2026 for the first time since January 2025, yet the Dallas–Fort Worth market still offers buyers room to negotiate on price (Realtor.com). That combination — higher borrowing costs and softer prices — is rare, and it's reshaping how smart buyers time their mortgage.
Why mortgage rates are climbing again in late 2026
The housing story of 2026 has been mortgage rates running higher than expected, with the outlook worsening as the year wore on. In September, rates surged roughly 40 basis points in a single month and crossed above 7% for the first time since January 2025 (Realtor.com). After a spring and summer where the market absorbed higher borrowing costs, that resilience gave way as inflation data and bond-market moves pushed borrowing costs back up.
Higher rates don't just change the monthly payment — they keep homeowners locked in place. Loans originated during the pandemic-era boom, when rates hit historic lows, now account for a record 42.8% of the U.S. mortgage market, and that share keeps growing (Realtor.com). Those homeowners would take a much more expensive mortgage to move, so they stay put. That tightens the supply of homes for sale and shifts negotiating power toward buyers who can act now.
For Texas buyers, that dynamic shows up in the data. Price cuts on active listings reached 20.8% in September, the highest single-month share since October 2022 (Realtor.com). Dallas–Fort Worth's median list price is down year over year while the supply of new homes continues growing. It's a slower market with more room to negotiate than Plano buyers have seen in years.
What the 2026 forecast actually says about rates
Fannie Mae's Economic and Strategic Research Group sees the 30-year fixed mortgage averaging 6.3% for full-year 2026, down slightly from 6.6% in 2025 (Fannie Mae). That forecast predates September's spike above 7%, so treat it as a trend line, not a promise. The range tells a more honest story: rates dipped toward 6.1% in early 2026 and then climbed back near 6.4% by midyear before crossing 7% in the fall.
A year-ago plan from Realtor.com expected rates to hold near 6.3% on average in 2026, enough to pull some buyers off the sidelines while keeping demand concentrated in more affordable markets (Realtor.com). That forecast has since been overtaken by events — but the underlying logic holds for Plano: when rates climb, sellers adjust, and that's where patient, prepared buyers win.
How should Plano buyers time their mortgage?
There's no single date that's right for every buyer, but three levers determine whether you come out ahead: the rate lock window, the loan term, and the Texas-specific closing costs you'll carry on top of the note rate.
A rate lock freezes your interest rate while you shop and close. With rates climbing, a longer lock — 60 to 90 days — protects you if rates keep rising before closing. The cost is a slightly higher lock-in fee or rate; the benefit is certainty in a rising market. If rates fall after you lock, some lenders offer a float-down option for a fee, letting you capture the lower rate without starting over.
Your loan term matters just as much. A 30-year fixed gives you a lower payment and more flexibility; a 15-year term saves tens of thousands in interest over the life of the loan but raises your monthly obligation. The right choice depends on how long you plan to stay and how much of your income you're comfortable committing to housing.
What Texas-specific costs should Plano buyers plan for?
The note rate is only part of the monthly cost. Texas has no state income tax, but homeowners make up for it with some of the highest effective property tax rates in the country. In Collin County, where Plano sits, that means a larger share of your payment goes to taxes than it would in many other metros — a figure you should get from an itemized loan estimate, not a rule of thumb.
Two more Texas realities shape your numbers. First, homeowners insurance and windstorm coverage have risen sharply across the state, so compare total monthly costs — principal, interest, taxes, insurance — not just the base payment. Second, Texas title and escrow fees run through a state-regulated rate schedule, which keeps them predictable but not negligible. When you compare two loan offers, the annual percentage rate (APR) is the better gauge because it folds in many of these fees.
A callout for first-time buyers: get pre-approved before you tour. In a market with rising rates, pre-approval tells you exactly what you can afford, locks in a rate window, and signals to sellers that your offer can close. Without it, you risk falling in love with a home you can't finance at today's rates.
Should you wait for rates to fall or buy now?
Buying now means locking in a higher rate but negotiating on price in a market where sellers are increasingly willing to bend. Waiting risks a repeat of 2021 — rates falling while prices keep climbing as inventory shrinks. Both paths carry risk, which is why the answer depends on your timeline, not a market prediction.
If you're buying for a specific life event — a growing family, a job move, a retirement plan — waiting for a marginally lower rate usually costs more in rent and price appreciation than it saves. If you're flexible, though, a 60-to-90-day window lets you watch the first inflation and Federal Reserve signals of early 2027 before committing. Realtor.com's economists note the fall is when negotiating leverage usually shifts toward buyers, and higher rates this year mean even fewer buyers than normal are showing up (Realtor.com).
The practical move is to get pre-approved now, lock a rate you can live with, and use the leverage a slower market gives you to negotiate on price, concessions, and closing costs — rather than gambling that a perfect rate will appear.
Your next step: a rate strategy, not a rate prediction
The most reliable way to win in this market is to stop trying to time the bottom and start building a strategy around certainty. Lock what you can afford, keep your lock window long enough to cover a real estate search, and negotiate the Texas costs — taxes, insurance, closing fees — that most buyers overlook.
If you're a Plano homebuyer weighing the 2026 numbers, a licensed mortgage advisor can run your specific scenario: what a 60-day lock costs versus a 90-day one, how property taxes and insurance change your qualifying payment, and whether a buydown makes sense for your timeline. The goal is not to guess where rates go — it's to know your number and be ready to act when the right home appears.
