Home equity is the portion of your home that you actually own, free and clear of any mortgage debt. You calculate it with a simple formula: take your home’s current market value and subtract what you still owe on your mortgage. If your home is worth $400,000 and you owe $250,000, you have $150,000 in equity. American homeowners collectively hold nearly $17 trillion in total home equity right now, making it the single largest source of wealth for most families.
How Home Equity Builds Over Time
Your equity grows in two ways. First, every mortgage payment you make chips away at your loan balance. In the early years of a mortgage, most of your monthly payment goes toward interest rather than reducing what you owe, so equity builds slowly at first and accelerates later. Second, if your home’s market value rises, your equity increases even without you doing anything.
The reverse is also true. If home prices in your area drop, your equity can shrink. In extreme cases, you can end up “underwater,” meaning you owe more than the home is worth. This happened to millions of homeowners during the 2008 housing crisis. Even in a stable market, neglecting maintenance and repairs can drag down your home’s value and erode equity over time.
Several factors influence how much your home is worth at any given moment. Local real estate conditions matter most: when comparable homes nearby sell for more, your home’s value tends to follow. Strategic renovations, like updating a kitchen or adding a bathroom, can push the number higher. Keeping up with routine maintenance protects the value you already have.
Tappable Equity vs. Total Equity
Not all of your equity is available to borrow against. Lenders use a concept called “tappable equity,” which is the amount you could withdraw while still keeping at least 20% equity in the home (an 80% loan-to-value ratio). If your home is worth $400,000 and you owe $250,000, your total equity is $150,000, but a lender would cap your borrowing so that your total mortgage debt doesn’t exceed $320,000 (80% of $400,000). That means your tappable equity is $70,000.
Across the country, approximately $11 trillion of the $17 trillion in total homeowner equity is considered tappable. Some lenders will stretch beyond 80%, letting you borrow up to 90% or more of your home’s value, but doing so means higher interest rates and greater risk.
Ways to Access Your Equity
There are three main tools for turning home equity into cash you can spend.
Home Equity Loan
A home equity loan gives you a lump sum upfront. You repay it in fixed monthly installments over a set term, often 5 to 30 years. Interest rates can be fixed or adjustable, though fixed rates are more common. This works well when you need a specific amount all at once, like funding a major renovation or consolidating high-interest debt into a single payment.
Home Equity Line of Credit (HELOC)
A HELOC works more like a credit card. You’re approved for a maximum credit limit and can draw from it as needed during a “draw period,” typically 10 years. As you repay what you’ve borrowed, the available balance replenishes. HELOCs usually carry adjustable interest rates, so your payment fluctuates with your outstanding balance and the current rate environment. This flexibility suits ongoing expenses or projects where costs are hard to predict in advance.
Cash-Out Refinance
With a cash-out refinance, you replace your existing mortgage with a new, larger one and pocket the difference. If you owe $200,000 on a home worth $400,000, you might refinance into a $280,000 mortgage and receive $80,000 in cash. This only makes financial sense when the new mortgage rate is competitive with what you’re already paying, since you’re resetting the clock on your entire loan.
What You Need to Qualify
Lenders typically require at least 15% to 20% equity in your home before they’ll approve an equity loan or HELOC. Beyond that, they evaluate your credit score, income, and existing debts. Some lenders accept credit scores in the 600s, and a few will go below 600 if you have strong income and significant equity. Higher credit scores generally unlock better rates and terms.
You’ll also need a current appraisal or valuation of your home so the lender can calculate your loan-to-value ratio. Most lenders cap total borrowing at 80% of your home’s value, though the exact threshold varies. Expect to provide pay stubs, tax returns, and documentation of other debts during the application process.
Costs of Borrowing Against Equity
Home equity products come with closing costs, just like a regular mortgage. Lenders and brokers charge points and fees that you pay at closing or roll into the loan balance. One point equals 1% of the loan amount, so one point on a $50,000 loan is $500. Traditional lenders typically charge between 1% and 3% of the loan amount in combined points and fees. If a lender quotes you more than 5% in total closing costs, that’s a signal to ask questions or shop elsewhere.
Points and interest rates work together: paying more in upfront points usually lowers your rate, while paying fewer points means a higher rate. Which approach saves money depends on how long you plan to keep the loan. Some lenders advertise “no closing cost” options but compensate by charging a higher interest rate over the life of the loan.
The Core Risk: Your Home Is Collateral
Every form of equity borrowing uses your home as collateral. If you can’t make the payments, the lender can foreclose and you lose the house. This is the fundamental tradeoff that separates home equity debt from unsecured borrowing like credit cards or personal loans. The collateral is why interest rates on equity products are lower than unsecured debt, but it also means the consequences of falling behind are far more severe.
There’s also market risk to consider. If property values decline after you’ve borrowed against your equity, you could owe more than the home is worth. That makes selling difficult and can leave you stuck in a property or forced to bring cash to closing just to complete a sale. Borrowing conservatively, well below your maximum tappable equity, provides a buffer against this scenario.
When Tapping Equity Makes Sense
Home equity is best used for expenses that either increase your home’s value (renovations that add more than they cost) or replace more expensive debt (consolidating credit card balances at 20%+ interest into a home equity loan at a much lower rate). Using equity for investments in your earning power, like funding education or starting a business, can also pay off if the returns exceed your borrowing costs.
Using equity for everyday spending, vacations, or depreciating purchases like cars is riskier. You’re converting a long-term asset into short-term consumption and putting your home on the line in the process. The lower interest rate can be tempting, but stretching a car purchase into a 15-year home equity loan means you’ll be paying for the vehicle long after it’s lost most of its value.
