Home equity is the difference between your home's market value and what you owe on your mortgage. If your home is worth $350K and you owe $200K, you have $150K in equity. Equity grows as you pay down your mortgage and as your home appreciates in value.
You can access equity through selling, refinancing, or a home equity line of credit (HELOC) without selling your home. For most American households, home equity is the largest source of personal wealth.
How Equity Builds
Home equity grows through two main mechanisms that work together over time:
- Principal payments: Each mortgage payment reduces your loan balance. Early on, most goes to interest, but over time more goes to principal.
- Appreciation: Your home's value increases over time as the market grows and neighborhoods improve.
- Home improvements: Strategic renovations that increase your home's market value add to your equity.
How to Calculate Your Equity
The formula is simple: Current market value minus mortgage balance equals your equity. If your home is worth $350K and your remaining mortgage balance is $200K, your equity is $150K. To express it as a percentage: $150K divided by $350K equals roughly 43% equity.
How to Access Your Equity
- Sell the home: When you sell, you receive your equity as cash after paying off the mortgage and closing costs.
- Cash-out refinance: Replace your mortgage with a larger loan and receive the difference in cash.
- Home equity loan or HELOC: Borrow against your equity with a second mortgage while keeping your first mortgage in place.
Why Equity Matters
Home equity is the single biggest wealth builder for most Americans. It gives you borrowing power for major expenses, a financial safety net in emergencies, and a substantial asset you can tap in retirement. Unlike rent payments that build zero wealth for you, mortgage payments build equity that belongs to you.
How Appreciation Affects Equity
In markets like San Antonio and the Texas Hill Country, home values have appreciated significantly over the past decade. Even if you have only been paying your mortgage for a few years, appreciation may have given you far more equity than your principal payments alone would suggest. A $250K home purchased in 2020 might be worth $325K today, creating $75K in equity through appreciation alone.
