Short answer: A HELOC is a separate line of credit behind your current mortgage, so you keep your first mortgage and its rate and borrow only what you need, when you need it. A cash-out refinance replaces your whole first mortgage with a new, larger loan and gives you the difference in cash, usually with closing costs and a new rate on the full balance. If you like your current mortgage rate and need flexible or smaller amounts, a HELOC often fits. If you want to restructure your whole mortgage into one payment, a cash-out refinance may be worth comparing. The right answer depends on your numbers, so compare both in writing.

The difference in one minute

The CFPB sums up the trade-off: with a cash-out refinance you replace your existing mortgage with a bigger one, often pay closing costs, and should look carefully at the new rate, especially if it's higher than your current one. Depending on the terms, a cash-out refinance may be more or less expensive than a HELOC.

When a HELOC may fit

• Your current first mortgage has a rate you'd rather keep.
• You need money over time, such as a remodel paid in stages, or you want a reserve you may not use right away.
• You need a smaller amount compared with your total mortgage balance.
• Speed matters. With a mostly online program, some eligible borrowers can get a decision in as little as 5 minutes and funding in as few as 5 days, subject to credit approval and verification. Timing is not guaranteed. See how long a HELOC takes.

When a cash-out refinance may fit

• Today's rates are similar to or lower than your current mortgage rate, so you aren't giving up a lower rate on your whole balance.
• You want one predictable payment, for example a fixed-rate loan, instead of a first mortgage plus a separate line.
• You need a large lump sum all at once and plan to stay in the home long enough to justify the closing costs.
• You want to change other things about your mortgage at the same time, such as the term or removing a borrower.

What to compare side by side

• Total cost over the time you'll keep the loan, not just the rate: fees, closing costs and the interest on the full balance (for a refinance) or only the drawn amount (for a HELOC).
• Your monthly payment now and later. Many HELOCs have a draw period followed by a repayment period, when payments can rise. Ask what the payment would be in each phase.
• Rate type. Variable or fixed, and any options to fix part of a balance.
• Future plans. If you have a HELOC and later want to refinance your first mortgage, the CFPB notes you may need the HELOC lender's approval, or you may need to pay off the HELOC.
• Taxes. Under IRS rules, interest on home equity debt is generally deductible only to the extent the money is used to buy, build or substantially improve the home that secures the loan. That applies whichever option you choose. Ask a tax advisor about your situation.

Two Washington examples

Kirkland remodel. A couple in Kirkland has a first mortgage with a rate well below today's and wants to redo their kitchen over several months. A HELOC lets them keep that first mortgage, draw as contractor invoices come in and pay interest only on what they've used.

Spokane consolidation. A homeowner in Spokane has a first mortgage with a rate close to today's, plus higher-cost debts, and wants one fixed payment. A cash-out refinance may be worth comparing, as long as the closing costs and the longer payoff on the whole balance make sense.

These are illustrations only, not offers. Your numbers decide which one fits.

Timing and your right to cancel

For a HELOC or a refinance on your primary residence, federal law generally gives you three business days after signing to cancel, so funds are released after that period. There are some exceptions; for example, when you refinance with your current lender, the right to cancel may apply only to the new money. A cash-out refinance usually takes longer than a HELOC, because it typically involves a full mortgage application, appraisal and title work.

I'll show you both options honestly, in writing, so you can decide with real numbers. No pressure. No obligation. Ask for a side-by-side comparison, or read how a HELOC works.

Common questions

Is a HELOC or a cash-out refinance better?

Neither is better for everyone. A HELOC often fits if you want to keep your current first mortgage and need flexible or smaller amounts. A cash-out refinance may fit if current rates are similar to or lower than yours and you want one payment. Compare total costs in writing.

Does a cash-out refinance replace my current mortgage?

Yes. A cash-out refinance pays off your current first mortgage with a new, larger loan, and you receive the difference in cash. The new rate and terms apply to the whole balance.

Do I keep my current mortgage with a HELOC?

Yes. A HELOC is a separate loan secured by your home behind your first mortgage, so your existing mortgage and its rate stay in place.

Which is faster, a HELOC or a cash-out refinance?

A HELOC is often faster. With a mostly online program, some eligible borrowers may get a decision in as little as 5 minutes and funding in as few as 5 days, subject to approval. A cash-out refinance usually takes longer. Timing is not guaranteed.

Is the interest tax-deductible?

It may be, but under IRS rules home equity interest is generally deductible only to the extent the money is used to buy, build or substantially improve the home that secures the loan. Please ask a tax advisor.

Can I refinance my first mortgage later if I have a HELOC?

Usually, but the CFPB notes you may need approval from the HELOC lender, and if it refuses you may need to pay off the HELOC to refinance.
