Homeowners Tapped $47 Billion in Equity in Q1. Could a Blended-Rate Refinance Make More Sense Than a Second Loan?

Why the Blended Rate Matters for a Cash-Out Refinance

The latest ICE data highlights a growing challenge for homeowners who want to access their equity without making their overall borrowing costs unnecessarily expensive.

Nearly two-thirds of second-lien borrowers in the first quarter had mortgages originated between 2020 and 2022, when mortgage rates were often between 3% and 4%. By taking out a home equity loan or HELOC, these borrowers could access additional funds without replacing their existing low-rate mortgage.

But preserving a low first-mortgage rate does not automatically make a second loan the least expensive option.

A blended mortgage rateis the balance-weighted average of the interest rates on a borrower's existing mortgage and additional home-secured debt. It offers a useful starting point for comparing the cost of keeping two loans against refinancing them into one new mortgage.

For example, a homeowner with a $300,000 mortgage at 3.5% who needs another $50,000 faces a choice between retaining the existing loan and borrowing the additional funds separately or refinancing the entire balance.

The second loan might carry a substantially higher interest rate than the original mortgage. However, because the existing mortgage represents most of the combined debt, the blended rate can remain relatively low.

A cash-out refinance that replaces the original mortgage and supplies the additional cash must be evaluated against that combined borrowing cost, not simply against the interest rate on the second loan.

How a Blended-Rate Comparison Works

Consider a hypothetical homeowner with the following balances and rates:

The blended rate is calculated by multiplying each loan balance by its interest rate, adding the results and dividing by the combined balance.

In this example, the blended rate is approximately 4.14%.

That figure does not mean the homeowner can automatically refinance the combined debt at 4.14%. It is a benchmark for comparing the existing two-loan arrangement with an available refinance offer.

If a homeowner could refinance the combined $350,000 balance at a hypothetical 6.25% rate, the new loan would have a higher nominal rate than the current blended rate. That could make preserving the original mortgage and adding a second loan more attractive from an interest-rate perspective.

However, the decision requires more than comparing percentages. The borrower must also consider monthly payments, remaining loan terms, closing costs, whether the second loan has a fixed or variable rate, and the total interest paid over the expected holding period.

A longer repayment term can lower a monthly payment while increasing the total interest paid over time. Likewise, refinancing may simplify debt management even when it does not produce the lowest overall borrowing cost.

Why Some Homeowners May Still Benefit From Refinancing

The argument for preserving a low-rate mortgage is compelling, particularly for borrowers who locked in rates near historic lows. But that does not mean every homeowner should automatically rule out a cash-out refinance.

The ICE report found that cash-out refinance withdrawals reached their highest first-quarter level since 2022. It also noted that nearly half of cash-out refinance activity came from borrowers whose mortgages originated in 2023 or later. Those homeowners are not necessarily giving up the same exceptionally low rates held by borrowers who financed during 2020 and 2021.

For some borrowers, a refinance can provide a practical way to combine the existing mortgage balance and new borrowing into one loan with one monthly payment.

The case for refinancing may be stronger when:

• The existing mortgage rate is already relatively high.Replacing it may be more competitive than retaining the first mortgage and adding a second lien.

• The borrower needs a substantial amount of equity.The size of the additional borrowing can materially change the blended rate and the economics of consolidation.

• The borrower wants to consolidate existing debt.Combining multiple obligations into a mortgage may simplify payments, although converting unsecured debt into debt secured by the home introduces foreclosure risk.

• The proposed refinance offers favorable total costs.A competitive rate, reasonable closing costs and a suitable repayment term may improve the overall comparison.

• The homeowner expects to remain in the property long enough to recover refinancing costs.The break-even period matters when evaluating whether upfront expenses are worthwhile.

The central question is not whether a refinance rate looks attractive in isolation. It is whether replacing the existing mortgage and adding new borrowing produces a better financial outcome than the alternatives.

The Lock-In Effect Is Keeping Equity Strategies in Focus

The growth in home equity borrowing reflects a housing market in which many owners have substantial equity but little incentive to surrender their existing mortgage terms.

According to ICE, approximately 3.9 million homeowners who took out primary mortgages between 2020 and 2022 now also have a second lien. The trend illustrates how borrowers have increasingly separated the decision to access equity from the decision to refinance their first mortgage.

That strategy has a clear rationale: a homeowner with a mortgage at 3.5% may be reluctant to replace the entire balance with a new loan carrying a considerably higher rate simply to access a portion of the property's accumulated value.

But the trade-off is that a second loan creates another obligation. A HELOC may also carry a variable rate, exposing the borrower to changing interest costs. Home equity loans generally offer a fixed rate, but their payments and terms can differ from those of the first mortgage.

For homeowners who are already carrying multiple loans, calculating the blended rate can help clarify the cost of maintaining that arrangement. For those who have not yet borrowed against their equity, it can provide a useful framework for comparing a second lien with a cash-out refinance before committing to either option.

Neither strategy eliminates risk. Both generally use the home as collateral, meaning missed payments can put the property at risk.

Home Equity Is Valuable, but the Repayment Plan Matters

ICE's June report identified approximately $11 trillion in available home equity, underscoring the scale of borrowing power held by U.S. homeowners. The first-quarter withdrawal figures also suggest that equity is increasingly being used as a source of liquidity while owners remain reluctant to sell or replace their existing mortgages.

Access to that equity can help fund necessary repairs, renovations or other planned expenses. It can also create financial strain when borrowing is used to cover recurring expenses without a sustainable repayment strategy.

For homeowners considering refinancing, the most useful next step is to compare actual loan offers using the same borrowing amount and a realistic repayment horizon.

That comparison should include the proposed new rate, the existing mortgage rate, any second-lien rate, closing costs, monthly payments and projected interest over the period the homeowner expects to keep the property.

A blended rate provides a starting point, not a guarantee of savings. Its value lies in making the trade-off visible: homeowners can assess the cost of preserving a favorable first mortgage alongside new debt against the cost of replacing both obligations with a single refinance.

As equity withdrawals remain elevated, that distinction could help borrowers make more informed decisions about how to access their home's value without overlooking the long-term cost of the money they borrow.
