Seventy percent of U.S. mortgage holders have rates below 5%. That freezes the traditional cash-out refi market and opens a door most lenders are ignoring: home equity as a core growth strategy.

The Big Picture

With $35 trillion in tappable equity across U.S. households, second liens have shifted from niche to necessity. Homeowners locked into low rates need liquidity without disrupting their first mortgage. Tom Davis, Chief Sales Officer at Deephaven, calls it "a generational opportunity."

The average U.S. home is 40-50 years old, driving a renovation surge expected to exceed $600 billion in 2026. Add $5 trillion in consumer debt, and equity becomes the go-to liquidity tool for consolidation, business funding, and portfolio expansion. The use cases are broad, but the message is clear: equity is the new refi.

“"More than 70% of borrowers don't return to their original loan officer for their next transaction. That's a massive missed opportunity."”

The macroeconomic backdrop reinforces this trend. The Federal Reserve has kept interest rates at a two-decade high, with the federal funds rate in the 5.25%-5.50% range since July 2023. This has crushed refinance activity: the Mortgage Bankers Association's Refinance Index is down over 70% from its 2021 peak. Meanwhile, home prices continue to climb, with the S&P CoreLogic Case-Shiller Index rising 5.2% year-over-year in Q1 2026. The combination of high rates and rising prices has inflated home equity to record levels, creating a perfect environment for second liens.

Lenders who adapt quickly can capture a significant share of this market. However, inertia is strong: many sales teams are trained to originate first mortgages and lack experience with second-lien products. Training and technology will be key to overcoming this gap. Firms that invest in automated underwriting systems for HELOCs and closed-end seconds can reduce closing times from weeks to days, giving them a competitive edge.

By the Numbers

• $35 trillion: Record tappable equity in U.S. households. This represents a 15% increase from 2024, driven by price appreciation and mortgage amortization.
• 70%: Share of mortgages with rates below 5%. Most of these loans were originated between 2020 and 2022, when rates averaged 3.5%.
• $600 billion: Projected home improvement spending in 2026, according to the Joint Center for Housing Studies at Harvard. This ranges from kitchen remodels to solar panel installations.
• $5 trillion: Total consumer debt, of which $1.2 trillion is credit card balances with average rates above 20%. Consolidating via equity can save households thousands in interest.
• 75%: Wealth of America's 24 million millionaires tied to home equity, per a Spectrem Group study. This underscores housing's central role in wealth accumulation.

Why It Matters

Most originators still chase purchase volume, ignoring a captive audience. Borrowers with low-rate first liens won't refi, but they will take a second lien if offered. Davis argues that lenders who fail to provide HELOCs, closed-end seconds, or DSCR products are leaving money—and client relationships—on the table.

Using blended-rate calculators, originators can show that a $50,000 second lien on a 3% mortgage beats refinancing the whole balance at 7%. That builds trust and retention. The originator who acts as a financial advisor, not just a loan closer, wins the long game.

Moreover, second-lien products offer more attractive margins than first mortgages. Industry data shows HELOC spreads can be 200-300 basis points above prime, while closed-end seconds can yield 8%-12%. In a compressed margin environment for purchase originations, these products provide a diversified and resilient revenue stream.

The retention impact is equally significant. An MBA study found that borrowers who obtain a second lien with their original lender are 60% more likely to return for future mortgage transactions. This creates a virtuous cycle of loyalty and repeat business.

What This Means For You

Whether you're a lender, homeowner, or investor, the equity wave is here. Here's how to ride it.

1. 1Lenders: Train your team on second-lien products. Recapture that 70% of borrowers who would otherwise walk. Implement blended-rate calculators and develop a financial advisory process. Consider partnering with technology providers that automate second-lien origination to reduce costs and closing times.
2. 2Homeowners: Consider a HELOC or closed-end second before tapping credit cards at 20%+. Your home equity is your cheapest capital. Consult a lender who offers equity products to compare options. Remember that HELOC interest may be tax-deductible if used for home improvements.
3. 3Investors: Use DSCR second liens to expand portfolios without disturbing low-rate first mortgages. Leverage is your friend. DSCR (Debt Service Coverage Ratio) loans qualify based on property cash flow, not personal income, making it easier to acquire multiple properties.

What To Watch Next

Two catalysts will shape this market: Fed policy and home-price trends. If rates stay elevated, refis remain frozen and equity products dominate. Also watch renovation spending—$600 billion signals strong demand for second liens. Any regulatory shift expanding second-lien access could accelerate adoption.

On the regulatory front, the Consumer Financial Protection Bureau (CFPB) has signaled its intent to review disclosure rules for HELOCs and second liens. Any changes that simplify origination could boost adoption. Conversely, tighter underwriting standards could slow growth. Market participants should monitor these developments closely.

Also important is the trajectory of long-term interest rates. If the Fed begins cutting rates in the second half of 2026, as some economists forecast, refinancing could revive, but second liens will remain relevant for those wanting to preserve ultra-low rates on their first mortgages.

The Bottom Line

Home equity is no longer a sideline product; it's the growth engine for 2026. Lenders who embed it as a core strategy will capture retention and origination share. Those who don't will be left behind. The generational opportunity is now—seize it. Lenders who act quickly will not only capture immediate revenue but also build lasting client relationships in a market where loyalty is increasingly scarce.
