Overview

What Is Home Equity Data?

Home equity data measures the portion of a property that an owner holds outright, calculated as the difference between the home's current market value and any outstanding debt secured by it. With U.S. homeowners collectively holding approximately $32 trillion in home equity, this asset class has become critical for lenders originating home equity loans and lines of credit (HELOCs). Parcel-level equity estimates enable lenders to identify qualified borrowers and structure competitive offers in an increasingly data-driven lending environment. Historically high and sustained home price appreciation has created unprecedented equity balances. The average American mortgage holder now has approximately $200,000 in tappable, or available, equity. Lenders rely on home equity data to evaluate borrower capacity for HELOCs and home equity loans—products typically offered at lower interest rates and used for debt consolidation, home improvements, and emergency reserves.

FAQ

Common questions.questions.

Why do lenders need home equity data at the parcel level?

Parcel-level equity estimates enable lenders to identify qualified borrowers for HELOCs and home equity loans, calculate maximum loan amounts based on available tappable equity, and structure competitive terms. Accurate, localized data also reduces underwriting time and improves risk assessment.

What is tappable equity and how much do U.S. homeowners have?

Tappable equity is the portion of a home's equity available to borrow against, calculated as home value minus mortgage balance and typically capped below 80% LTV. The average U.S. mortgage holder now holds approximately $200,000 in tappable equity, with some borrowers gaining as much as $36,000–$37,000 in recent years.

Are automated valuation models (AVMs) replacing traditional appraisals for home equity lending?

AVMs are gaining market share in home equity lending due to speed and cost-effectiveness. In the first half of 2024, lenders used AVMs and property condition reports on 35% of home equity loans (up 20 percentage points year-over-year), compared to full appraisals on 17% of loans. However, traditional appraisals and hybrid products remain in use depending on loan size and lender risk appetite.

How strong is the HELOC market currently?

The HELOC market is experiencing robust growth. HELOC volumes have doubled since January 2021, and record untapped equity levels are making HELOCs increasingly attractive to borrowers for debt consolidation, home remodeling, and emergency reserves. Lenders view the current equity environment as having significant profit potential for 2025 and beyond.
