Home Equity Line of Credit (HELOC)

A home equity line of credit (HELOC) is a revolving credit line secured by your house. Think of it as a credit card with your home equity as the limit and a much lower rate. You borrow only what you need, pay interest only on what you’ve drawn, and your existing first mortgage stays exactly as it is.

How it works

A HELOC has two phases:

The draw period, typically 10 years. You can borrow, repay, and re-borrow up to your credit limit, usually by transfer, check, or card. Minimum payments during this phase are often interest-only, which keeps them low but doesn’t reduce the balance.
The repayment period, typically 10 to 20 years after the draw period ends. The line freezes and the balance amortizes into principal-and-interest payments. This is where the payment shock lives: an interest-only payment on a large balance can jump substantially when amortization begins.

Rates on most HELOCs are variable, pegged to the prime rate plus a margin, so your cost moves with the broader rate environment. Some lenders offer fixed-rate lock options on portions of the balance, which are worth asking about if you plan to carry a balance for years.

Your credit limit is set by your combined loan-to-value (CLTV): first-mortgage balance plus the HELOC limit, divided by home value, typically capped at 80%–90%. Example: a $400,000 home, a $250,000 first mortgage, and an 85% CLTV cap allow a line of up to about $90,000.

Who qualifies

Typical benchmarks (individual lenders vary and nothing here is a promise of approval):

Credit score: 640–680 minimum at most lenders; the best pricing typically starts around 720+
Equity: enough that your combined LTV lands under the lender’s cap (80%–90% typically)
Debt-to-income ratio: typically 43%–50%, counting a payment on the full line amount in many cases
Income documentation: standard pay stubs/W-2s or tax returns; some lenders offer bank-statement HELOCs for self-employed borrowers (see our self-employed loan options)
Property: primary residences get the best terms; second homes and investment properties are possible at lower CLTV caps

What it costs

HELOCs are typically cheaper to open than a refinance:

Closing costs: often low or waived, though “no-cost” lines may include early-closure recapture fees if you close within the first few years
Annual fee: commonly $0–$100
Appraisal: many lenders accept an automated valuation instead of a full appraisal, which speeds things up
The real cost: variable-rate interest on your drawn balance. Model a rate a couple of points higher than today’s before committing, because prime can and does move

Pros and cons

Pros

Pay interest only on what you actually draw; an open, unused line costs little or nothing
Leaves a low-rate first mortgage completely untouched
Reusable during the draw period: borrow, repay, borrow again
Fast and cheap to open compared with a refinance

Cons

Variable rate means your payment can rise without warning
Interest-only minimums make it easy to carry debt for a decade without progress
Payment jump at the end of the draw period catches many borrowers off guard
Your home is the collateral, so this is not the place for speculative or discretionary borrowing
Lenders can freeze or reduce lines if home values fall or your credit deteriorates

HELOC vs. the nearest alternatives

Cash-out refinance: replaces your whole first mortgage with a bigger one and gives you a lump sum at a fixed rate. Better when you need a large, known amount and your current mortgage rate is at or above today’s market. Worse when your first mortgage carries a low rate you’d be giving up.
Home equity loan: the fixed-rate, lump-sum sibling of the HELOC. Same second-lien position, but with a predictable payment, making it a good middle path for a single defined project.
Rate-and-term refinance plus savings: if what you really want is a lower payment rather than cash, compare a straight refinance first. Our mortgage calculator suite can help you compare payments across scenarios.

Home Equity Line of Credit (HELOC): your questions, answered

How is a HELOC different from a home equity loan?

A HELOC is a revolving credit line: you draw what you need, when you need it, and pay interest only on the outstanding balance, usually at a variable rate. A home equity loan hands you one fixed lump sum with a fixed rate and fixed payment. Ongoing or uncertain expenses favor the line; a single known expense favors the loan.

What can I use a HELOC for?

Anything. Common uses are home renovations, tuition, debt consolidation, and as an emergency reserve. Interest is generally tax-deductible only when the funds buy, build, or substantially improve the home securing the line, so check with a tax professional. Because your house is the collateral, funding volatile investments or lifestyle spending with a HELOC deserves real caution.

Do HELOC payments change over time?

Usually, yes, in two ways. The variable rate moves with the prime rate, so your interest cost can rise or fall while you hold a balance. And when the draw period ends, payments convert from interest-only to fully amortizing principal-and-interest, which can be a significant jump. Plan for it from day one.

How much can I borrow on a HELOC?

Most lenders cap your total housing debt (first mortgage plus the HELOC limit) at 80% to 90% of your home's value. On a $400,000 home with a $250,000 first mortgage, an 85% cap works out to a line of up to about $90,000. Your credit, income, and the lender's specific overlay set the final number.

Does opening a HELOC affect my first mortgage?

No. A HELOC sits in second position behind your existing mortgage, which keeps its rate, term, and payment unchanged. That's the main reason HELOCs are popular when homeowners have a low first-mortgage rate they don't want to give up.

Can I get a HELOC with no closing costs?

Many lenders advertise low or no closing costs on HELOCs, sometimes in exchange for keeping the line open a minimum period; closing early can trigger a recapture fee. Watch for annual fees, minimum-draw requirements, and inactivity fees in the fine print. Total cost of ownership matters more than the headline.
