US Homeowners Hold $11.7 Trillion in Tappable Equity as Second Liens Gain Ground

United States | October 21, 2026: A massive pool of home equity is sitting on the sidelines in the US housing market, but homeowners looking to unlock that capital are still largely turning to debt. About $11.7 trillion of tappable equity was held by 47.5 million mortgage borrowers in Q2 2026, according to ICE data.

The trend is highlighting a gap in the residential property market. Owners can sell their homes or borrow against them, but there is still no widely adopted, standardised way to sell a defined portion of property ownership and raise capital without taking on another loan.

Second liens have become a key equity-access route

ICE data shows that 54% of equity-tapping activity in Q1 2026 involved second liens. The preference is partly linked to the large number of homeowners holding older mortgages at comparatively low interest rates.

For these owners, refinancing an existing first mortgage can mean giving up a cheaper loan. A second lien allows them to access additional capital while leaving the original mortgage untouched.

The approach, however, comes with a new borrowing cost and increases the property's overall debt burden.

$11.7 trillion in equity remains available to borrowers

The latest ICE Mortgage Monitor estimates put total home equity held by US mortgage borrowers at approximately $18 trillion in Q2 2026, with around $11.7 trillion classified as tappable equity.

That figure represents a significant source of potential capital for homeowners and property investors. Yet turning that equity into usable funds remains closely tied to conventional lending products.

For owners who do not want to sell their entire property, the existing choices remain relatively limited.

 

Real estate ownership is divisible but not easily tradable

Property ownership can already be split through structures such as tenancy-in-common interests, LLC interests and real estate syndications. But these arrangements are typically customised for individual assets.

That makes them different from standard financial products where investors know what they are buying and can compare one investment with another.

A more standardised form of fractional ownership could potentially allow property owners to sell a defined share of an asset while retaining the rest. The concept would give equity a more direct route into the capital market without requiring the owner to take on another loan.

The numbers show when selling equity could make sense

The potential advantage becomes clearer with an income-producing property.

Take a $500,000 property carrying a $250,000 first mortgage at 4.5%. If the owner wants to raise another $100,000, they could take an 8.5% second lien or sell a 20% ownership interest.

At a 5% cap rate, the property generates $25,000 in annual NOI. A 20% ownership share represents $5,000 of that income, compared with $8,500 in annual interest on an 8.5% second lien.

At an 8.5% cap rate, the two costs become equal. Above that point, the second lien becomes cheaper from a simple annual cash-flow perspective.

The calculation points to an important property-investment principle: when borrowing costs exceed the income yield of an asset, selling part of the equity can potentially preserve more cash flow than adding debt.

Owners could trade debt for shared future returns

The biggest difference between the two approaches is risk.

A second lien creates a fixed financial obligation. The borrower must make payments regardless of changes in rental income, operating expenses or property performance.

A partial-equity transaction would work differently. The owner would receive capital upfront in exchange for giving another investor a defined share of future income and potentially future appreciation.

This would mean giving up part of the property's upside, but it could avoid another monthly debt obligation and the additional leverage associated with a second mortgage.

For income-property owners facing higher insurance, taxes and operating costs, that distinction could become increasingly important.

 

Could fractional equity become the next property-finance product?

The concept could eventually extend beyond investment properties. A homeowner could theoretically retain a chosen percentage of a property while selling another portion to investors through a standardised ownership structure.

That would create a middle ground between owning an entire property and selling it altogether.

But building such a market would require clear rules around valuation, ownership rights, governance, taxation, investor protections and transfers. Technology alone would not solve those issues.

What this means for property owners

The growing use of second liens shows that American homeowners have substantial equity but still have limited ways to access it.

For now, borrowing remains the established route. A standardised equity product could change that equation by allowing owners to unlock part of their property's value without adding another layer of debt.

For investors, the emergence of such a market could also create a new class of real estate opportunities. But whether fractional property ownership becomes mainstream will depend on the development of a trusted framework that makes these interests easier to price, buy and sell.
