What Is Home Equity?
The Simple Formula
Equity = Current Home Value – Remaining Mortgage Balance
If your home is worth $400,000 and you owe $320,000, you have $80,000 in equity. That's $80,000 of real wealth that belongs to you.
Think of equity like a savings account that grows in two ways: every mortgage payment chips away at your loan balance (like depositing money), and if your home's value increases, your equity grows even without you doing anything extra (like earning interest). Together, these two forces can build substantial wealth over time.
How Equity Builds Over Time
Through Mortgage Payments
- Each monthly payment reduces your loan balance (this is called "amortization")
- Early payments are mostly interest — principal paydown is small at first
- Over time, more of each payment goes toward principal
- By year 15 of a 30-year mortgage, roughly half your payment goes to principal
- This is "forced savings" — equity builds automatically with every payment
Through Appreciation
- If your home's value increases, your equity grows without any extra effort
- DFW has seen strong appreciation over the past decade
- Even 3% annual appreciation on a $375K home adds $11,250 in equity per year
- Appreciation compounds — each year's gain is on top of the previous year's
- Not guaranteed — markets can plateau or temporarily decline
Real Example: 5 Years of Equity Growth
You buy a $375,000 home with 5% down ($18,750). Your mortgage is $356,250. After 5 years of regular payments and 3% annual appreciation, your home could be worth about $435,000, and your loan balance would be around $330,000. Your equity: approximately $105,000 — from an initial investment of $18,750. That's the power of leveraged appreciation combined with loan paydown.
Strategies to Build Equity Faster
Make Extra Principal Payments
Even an extra $100/month toward principal can shave years off your mortgage and save tens of thousands in interest. Most lenders allow extra payments — just specify that the extra goes toward principal, not future payments.
Make Biweekly Payments
Instead of 12 monthly payments, make half-payments every two weeks. You'll make 26 half-payments = 13 full payments per year (one extra payment). This alone can pay off a 30-year mortgage in about 25 years.
Apply Windfalls to Your Mortgage
Tax refunds, bonuses, or unexpected income can make a big dent. A single $3,000 extra payment early in your mortgage can save $8,000–$10,000+ in total interest over the loan's life.
Make Strategic Home Improvements
Not all improvements add value equally. Kitchen and bathroom updates typically return 60–80% of their cost. Curb appeal improvements (landscaping, paint, new front door) often return even more. Avoid over-improving for your neighborhood.
Refinance to a Shorter Term
If rates drop or your income increases, refinancing from a 30-year to a 15-year mortgage dramatically accelerates equity building. Your payment will be higher, but far more goes toward principal.
Avoid Cash-Out Refinancing (Usually)
Cash-out refinancing lets you borrow against your equity, but it resets your mortgage balance higher. Use this only for investments that generate returns (education, high-ROI renovations) — never for consumer spending.
How to Access Your Equity
Once you've built equity, there are several ways to access it if needed:
Sell the Home
The most straightforward way. When you sell, you pay off the remaining mortgage and keep the profit (your equity). If you've lived there 2+ years, up to $250K in profit ($500K married) is tax-free.
HELOC (Home Equity Line of Credit)
A revolving credit line secured by your home equity. You borrow only what you need and pay interest only on what you use. Great for home improvements or emergency funds. Variable interest rates — be cautious.
Home Equity Loan
A lump-sum loan with a fixed interest rate, repaid in fixed monthly installments. Good for one-time large expenses with predictable payments. Your home is collateral — if you can't repay, you could lose it.
Borrow Against Equity Carefully
Your home is your collateral. If you borrow against your equity and can't make the payments, you risk foreclosure. Only borrow against equity for investments that improve your financial position (home improvements, education, debt consolidation at lower rates) — never for vacations, cars, or consumer purchases.
Key Takeaways
Equity = Home Value – Mortgage Balance. It's the portion of the home you actually own.
Equity builds two ways: through mortgage payments and home appreciation — both work simultaneously
Extra principal payments — even $100/month — can save tens of thousands in interest over the loan's life
Up to $250K in home sale profit is tax-free ($500K married) if you've lived there 2+ years
Borrow against equity carefully — your home is the collateral, and misuse can lead to foreclosure
Strategic home improvements build equity through forced appreciation — focus on kitchen, bath, and curb appeal
