Will mortgage rates go down in 2026, or stay around 6% (especially for Collin County buyers)?

If you’re house-hunting in Collin County right now, you’ve probably realized one thing: the rate matters just as much as the price. The good news is that rates ended 2025 lower than they started, and we kicked off 2026 with the 30-year fixed mortgage averaging 6.15% (Freddie Mac’s weekly survey). Freddie Mac+1

Here’s how I translate that into real life for a Collin County Texas home buyer in 2026.

Collin County is not a “cheap payment” market. Even with some price softening, our county still has a higher price point than many parts of Texas. Redfin shows Collin County’s median sale price around $435,000 in November 2025, and homes were taking longer to sell (more on that in a second). Redfin

At a 6.15% rate, the difference between “I’ll wait for rates” and “I’ll buy the right home” gets very personal. Because in Collin County, a slightly lower rate can mean a meaningful monthly swing. Rates do not need to crash to help you. Even modest drops can improve buying power, especially when sellers are more negotiable than they were a couple years ago.

So are rates going down in 2026? Nobody can promise that, and anyone who does is guessing. What we can say is this: the market ended 2025 around the low 6’s nationally, and many forecasts are basically calling for a “slow grind” rather than a dramatic shift. Freddie Mac+1

What Collin County buyers should do with that info

Instead of trying to time the absolute bottom, I coach people on a more practical plan:

• Get qualified with today’s rate, not your dream rate. If you can comfortably afford the payment at current terms, you are in control.

• Shop the house and the terms. In a softer market, the negotiation is not just price. It can be closing costs, rate buydowns, repairs, and timing.

• Stay flexible by area. Frisco, Plano, and McKinney are not moving in perfect unison. For example, Redfin showed Frisco down year over year in November 2025 (median about $675K), while parts of Plano were closer to flat. Redfin+1

If you’re searching “2026 mortgage rates” and feeling stuck, here’s the punchline: you do not need a miracle rate to win in Collin County in 2026. You need a smart plan, a strong lender, and a strategy that uses this more balanced market to your advantage.
