Why More Sellers Are Moving On from Their 3% Mortgage Rate

Many homeowners in Miami and the Florida Keys feel stuck because they don’t want to give up their 3% mortgage rate. It’s understandable — that rate has been a major financial advantage. But a great rate can’t fix a home that no longer fits your life. And more people across South Florida are starting to make moves anyway.

The “lock-in effect” is slowly easing. Data from the Federal Housing Finance Agency shows the share of homeowners with rates below 3% is shrinking, while more mortgages now carry rates above 6%. Some of that shift comes from first-time buyers, but many are local homeowners choosing to move despite higher rates.

Why? Because life keeps moving. Families expand, jobs change, aging parents move closer, or homeowners simply outgrow their current space. As Redfin notes, lifestyle needs are starting to outweigh the benefit of keeping a rock-bottom rate.

Economists often refer to the “5 Ds” — Diplomas, Diapers, Divorce, Downsizing, and Death — as the biggest drivers behind these decisions. Those same factors are influencing moves throughout Miami, Key Largo, and the Upper Keys. Realtor.com reports nearly two-thirds of potential sellers have been thinking about moving for more than a year, showing just how many people feel stuck.

Rates are already down from their earlier peak, and forecasts suggest gradual improvement into 2026. For many homeowners, that shift is enough to finally unlock their next chapter. As a Miami and Keys real estate agent with The Selling Properties Group powered by LPT Realty, I’m seeing more movement from sellers who are ready for a home that fits their life again.
