At a glance

  • The shift: 88% of the record $13.2 trillion sits behind a cheaper mortgage [1].
  • The number: $11.6 trillion is locked in, below a benchmark the market has left [1].
  • The risk: At 7.18%, the locked share grows with rates, not choices [2].

The benchmark moved, not the lock

First American Data & Analytics published its first accessible-equity report on October 28, 2026, measuring the market as of June 30, 2026, when the average 30-year rate was 6.49% [1]. Freddie Mac’s weekly survey put the same average at 7.18% on November 5 [2]. Between those readings, the bar a mortgage must clear to count as locked rose by 0.69 points.

The report counts equity as locked when an owner’s own mortgage rate sits below the going rate, because replacing that loan would cost more than keeping it [1]. A homeowner at 6.6% was not locked on the June date, since 6.6 sat above 6.49. The same owner is locked now, since 6.6 sits below 7.18. Nothing about the house changed, and nobody borrowed a dollar.

That reclassification is arithmetic on the report’s own definition, and it is the part of the story neither document states. One measures a stock of equity sorted by rate. The other measures the price of money one week at a time.

Most of the locked money sits far from the market. The sharpest band holds 83% of it, at rates more than 1.5 points below the benchmark and therefore below 4.99% [1]. Overall, 87% of locked-in equity is severely or extremely locked in [1]. I read the severity table twice before I trusted the direction.

The report’s own trend shows the mechanism from the other side. Rates eased between mid-2025 and mid-2026, so locked-in equity fell 2% while the total rose 1.5% [1]. The least locked band grew 25% over that year, and every state still reported at least three quarters of its eligible equity as locked; South Dakota topped the list at 98.0% and Connecticut was lowest at 74.6% [1].

By the numbers

  • $11.6 trillion locked in: Equity held by owners whose first mortgage sits under the 6.49% benchmark [1].
  • 83% of it extreme: Locked equity held by owners at least 1.5 points under that benchmark, a band below 4.99% [1].
  • 0.69 points wider: The distance the going rate has risen since, to 7.18% in the latest survey [2].

Where the borrowing decision splits

Most locked money sits in the extreme band, and that concentration is why lenders read the report as a map of the second-lien market. Replacing a mortgage priced under 5% with one at 7.18% raises the cost on every dollar owed. A second lien, such as a home equity line or a fixed home equity loan, raises the cost only on the amount drawn, so the cheap first mortgage stays where it is [1]. The two routes differ in what they reprice, which is the distinction a HELOC and ARM stress test exists to make plain.

A roof at the end of its life makes the same claim on a household whether or not the mortgage under it is cheap. On a $250,000 balance, a move from 6.49% to 7.18% adds $1,725 a year before the owner draws a cent for the work [2]. That $250,000 balance is an assumption, not a published figure. A second lien on a $30,000 roof charges its rate on $30,000 alone, so when a job is small against the balance, the loan that looks more expensive is often the cheaper one.

The group I am watching is the band of owners close to market. Its low and moderate bands rose from about 10% at the end of 2025 to 13% in the second quarter [1]. Those owners sit close enough to market that a cash-out refinance stops being a penalty and starts being a sideways move, and the trade press describes the near-market group the same way [3]. The next report in December will show whether that 13% is a trend or one quarter.

The catch

The two anchors are not one series. First American’s 6.49% is its own national average at quarter end [1]. Freddie Mac’s 7.18% covers conventional purchase loans with 20% down and excellent credit [2]. Subtracting one from the other gives direction with more precision than level.

Accessible equity is also an estimate, not a credit line. The publisher assumes a total loan-to-value at or below 80% and warns that real borrowing depends on underwriting and the owner’s own finances [1]. My figure of about $1.6 trillion for the reachable remainder comes out of four rounded bands and a rounded total, so it stays approximate by construction.

I could be wrong, but the direction matters more than the label. Locked in is an incentive to keep a cheap loan, not a bar on borrowing. A fall in rates would loosen the lock as quietly as this rise tightened it. The reachable share was 12% in June [1], and the market has spent the four months since pushing it back down.
