Using a HELOC to pay off credit card debt: when it works, and the rules I set first

A HELOC is a line of credit recorded as a second lien behind your current mortgage. You draw what you need — in this case, enough to zero out the cards — and your first mortgage, its balance and its rate stay exactly as they are. That last part is why a line usually beats a cash-out refinance for someone with a first mortgage worth keeping.

The line is sized from your equity, not your income. Take your home’s value × 90% (80% in Texas), subtract what you owe on the first mortgage, and that’s the most the line can be.

Example: a $650,000 home with $380,000 owed. $650,000 × 90% = $585,000. Subtract $380,000 and there’s room for a line of up to about $205,000 — more than enough for $62,000 spread across four cards. The real number depends on the valuation and approval.

Because lines start at $50,000, this fits best when the card balances are in that range or above. For a smaller balance, I’ll tell you plainly whether a HELOC is still worth it for you.

1. 1

   You own the home and want to keep your first mortgage

   The line sits behind it, so nothing about that loan changes.

2. 2

   Your score is 620 or higher

   That’s a firm floor for this HELOC. Under 620, see the alternative below.

3. 3

   There’s equity room

   Run the 90% math above. If the room covers the balances with space to spare, you’re in range.

4. 4

   Your cash flow can pay it down

   Not just cover the interest — pay down the principal. If the debt came from income that still doesn’t cover the bills, moving it won’t fix that.

5. 5

   You know what caused the balances

   A one-time event (a medical bill, a slow year, a roof) is a good fit. A spending pattern that hasn’t changed is not.

Under 620? A Home Equity Agreement works with credit in the 500s and has no monthly payment — you share a portion of your home’s future value instead. It’s available on primary homes in 11 states. The HEA vs. HELOC guide compares the two.

• Draw the payoff amount, not the whole line. The extra room is for emergencies, not for spending. Every dollar you draw is secured by your home.
• Pay principal from day one. This line has an interest-only option. Using it on consolidated card debt just parks the balance on your house. We set a principal paydown target that clears it on your timeline.
• Take the paid-off cards out of daily use. Whether to close them is a credit-score conversation we have on your file — but the cards themselves leave the wallet.
• Keep a cushion. If paying the line leaves nothing for a bad month, we size it differently or look at another option.

A lot of the card debt I see comes from business owners whose write-offs make their tax returns look thin, so the bank declines the equity line. This HELOC doesn’t use tax returns. If income paperwork is the whole problem, the no income verification HELOC qualifies on credit and equity alone for qualifying files.

In Texas, the state constitution (Art. XVI §50(a)(6)) limits home equity borrowing to 80% combined loan-to-value and requires a minimum 12-day wait before closing. The same strategy works — the equity math just uses 80%, and the timeline is 12 days.

1. 1

   A soft credit check

   We go over the balances and your goal, and I compare options across 100+ lenders. No hard pull to see where you stand.

2. 2

   Three documents

   Government ID, your current mortgage statement and proof of homeowners insurance. Underwriting may ask for more, but tax returns won’t be on the list.

3. 3

   Valuation runs on its own

   On lines up to $1,000,000, an automated valuation replaces the appraiser’s visit.

4. 4

   Funds in as little as 5 business days

   When the file is clean. Texas follows its 12-day minimum. Then the cards get paid and the rules above kick in.
