Keep your low rate. Borrow against the rest.
A HELOC leaves your first mortgage completely untouched. That's why it usually beats a cash-out refinance. Now here's the part nobody tells you: it's variable, it's interest-only, and there's a cliff at year ten.
A HELOC is a revolving credit line secured by your home, and it leaves your first mortgage exactly as it is — which is why it usually beats a cash-out refinance when you hold a low rate. The trade-offs are real: the rate is variable, payments during the draw are interest-only, and when the draw ends the payment jumps.
Ten years of payments. Zero progress.
During the draw period you pay interest only. It feels wonderfully manageable. Watch what your balance does.
This is variable. Drag it and see what your future looks like.
Illustrative only. HELOC rates are variable and tied to an index plus a margin; they can rise and fall over the life of the line. Draw and repayment periods vary by lender. Not a commitment to lend. Equal Housing Opportunity.
Then the draw ends — and the payment jumps.
Principal kicks in. And if the rate moved against you while you weren't looking, it jumps twice.
Prime moves. In 2022 it moved 4.25 points in a year.
At the cliff your payment goes from $1,063 to $1,302 — because you finally start repaying what you borrowed. If prime has climbed to 13% by then, it becomes $1,757. Plan for the cliff on the day you open the line, not on the day you reach it.
HELOC or cash-out? It depends entirely on your rate.

At 3.25%, the HELOC wins by $1,376 a month — $495,327 over thirty years. Your first mortgage is worth protecting.
$600,000 balance, $150,000 needed. HELOC assumes an 8.5% interest-only draw with your first mortgage untouched. Cash-out assumes a new 30-year at 7% with costs financed. Illustrative only.
Is a HELOC right for you?
Four taps. This page sells HELOCs and will tell you when to take something else.
A HELOC is your tool.
You hold a below-market first mortgage, you can absorb rate movement, and you don't need the whole sum at once. That is precisely the case a HELOC was built for — you keep the cheap money you already have and borrow only what you actually use.

Everything people actually ask.
What is a HELOC?
A home equity line of credit is a revolving line secured against your home. You are approved for a limit, you draw what you need, and you pay interest only on what you have drawn. Your first mortgage stays exactly where it is — which is the entire point.
Why would I take a HELOC instead of a cash-out refinance?
Because a cash-out refinance re-prices your whole mortgage at today's rate. If you hold a 3% loan, that is catastrophically expensive. A HELOC leaves that rate untouched and only charges you on the money you actually use. When you have a below-market first mortgage, the HELOC usually wins by a very wide margin.
Is a HELOC rate fixed?
Almost never. HELOC rates are typically variable, tied to the prime rate plus a margin. If prime rises, your payment rises — with no cap in most cases beyond a lifetime ceiling. This is the single most important thing to understand, and it is the thing least often said out loud.
What is the draw period?
Usually ten years. During the draw you can borrow, repay, and borrow again, and your required payment is typically interest only. It feels wonderfully cheap. That feeling is the trap.
What happens when the draw period ends?
Repayment begins — typically over twenty years — and your payment jumps, because you are now paying principal as well as interest. On $150,000 at 8.5% that is roughly $1,063 rising to $1,302. If rates have moved against you, the jump is far larger.
If I only pay interest, what happens to the balance?
Nothing. It does not move. Ten years of interest-only payments on $150,000 at 8.5% costs about $127,500 — and at the end you still owe the entire $150,000. The money is gone and the debt is intact. This is not a defect; it is how the product works, and you must go in knowing it.
How much can I borrow?
Most lenders allow a combined loan-to-value of around 80% to 90% of your home's value, including your first mortgage. Programs and limits vary, and California valuations move — the number you qualify for today is not a number you can bank on forever.
Can the bank reduce or freeze my line?
Yes. Lenders can freeze or reduce a HELOC if your home's value drops or your circumstances change. This happened at scale in 2008 to people who were relying on the line as an emergency fund. A HELOC is a good tool; it is a fragile safety net.
Are HELOC closing costs high?
Usually far lower than a refinance — sometimes near zero, though some lenders recover them if you close the line early. Because you are not touching your first mortgage, there is much less to pay for.
When is a HELOC the wrong choice?
When you need a large, fixed, one-time sum and current rates are at or below your existing mortgage rate — a cash-out refinance may then be cheaper and safer, because it fixes the rate. And it is the wrong choice, always, if you are using it to fund a lifestyle rather than an asset.
