What Is Home Equity?

What Is Home Equity?

Home equity is the difference between your home's current market value and the outstanding balance on all loans secured by the property. If your home is worth $500,000 and you owe $320,000 on your mortgage, your equity is $180,000. Equity increases as you pay down your mortgage balance and as the home's value appreciates over time.

How Equity Builds

Equity grows through two mechanisms: principal paydown and appreciation. In the early years of a mortgage, most payments go toward interest, so equity builds slowly through paydown. As the balance decreases, more of each payment reduces principal and equity grows faster. Appreciation-driven equity requires no action on the homeowner's part.

How to Access Home Equity

Homeowners can access equity through: a cash-out refinance (replaces the existing mortgage with a new, larger loan), a home equity loan (fixed-rate installment loan for a lump sum), or a HELOC (revolving credit line secured by equity, typically with a variable rate).

How Much Equity You Can Actually Borrow

On a $425,000 home with a $280,000 balance, equity is $145,000 (34.1%). But lenders cap combined loan-to-value around 85% -- 85% of $425,000 is $361,250, minus the $280,000 balance leaves about $81,250 actually available through a HELOC or home equity loan, well below the full $145,000 of paper equity.

Equity and LTV

Lenders measure equity through the loan-to-value (LTV) ratio: LTV = Outstanding Loan Balance / Appraised Value. An LTV below 80% (equity above 20%) eliminates PMI on conventional loans. Most lenders cap HELOCs and cash-out refinances at a combined LTV of 80% to 85%.

Common Equity Mistakes

Assuming all your equity is borrowable. As shown above, lenders leave a cushion, so your maximum HELOC or home equity loan is smaller than your total equity.

Treating equity like free cash. Borrowing against equity still creates debt secured by your home, with your home as collateral if you can't repay.
