To tell if your mortgage is a HELOC, look at three things: the title printed on your closing documents, the format of your monthly statement, and how your account is labeled on your credit report. A home equity line of credit shows a credit limit, an available balance, and individual draw transactions, much like a credit card. A standard mortgage shows a single declining principal balance and a fixed payoff schedule. If you see “open-end” anywhere on the loan agreement, or a “draw period” on your statement, you have a HELOC.
The distinction matters because the two loans behave differently over time. A HELOC is revolving credit secured by your home: you can borrow, repay, and borrow again up to a set limit during a draw period that usually lasts three to ten years. A conventional mortgage hands you a lump sum at closing and you pay it down on a fixed schedule. Which one you carry affects your tax deductions, your refinance options, and what your payment looks like years from now.
Start With Your Monthly Statement
The fastest check is the bill that arrives every month. A HELOC statement reads like a credit card bill. It lists a credit limit, an available balance you can still draw against, and individual transactions for any advances taken during the billing cycle. Federal rules require HELOC servicers to itemize each draw on the periodic statement, so active borrowing shows up as specific withdrawal amounts and dates.
A standard mortgage statement looks nothing like that. You’ll see one declining principal balance, a payment amount that stays the same or changes only slowly, and a maturity date somewhere in the future. There’s no “available credit” line because there’s nothing left to borrow. A line item labeled “draw period,” or any available-credit figure sitting next to your current debt, points to a HELOC.
Read the Title on Your Closing Documents
Your closing paperwork is the definitive legal record of what you signed. Pull the folder from closing day, check your lender’s online portal, or request copies from the county recorder’s office where the lien was filed. The title printed on the agreement is what you’re after.
A HELOC is usually labeled “Home Equity Line of Credit Agreement and Disclosure” or “Open-End Deed of Trust.” The word “open-end” is the giveaway. It means the lender structured the loan so you could borrow repeatedly against the same lien. The HELOC agreement will also carry disclosures about variable rates, the length of the draw period, and the conditions under which the lender can freeze your line. Federal law requires these disclosures to appear prominently and grouped together.
A conventional mortgage is titled “Promissory Note” or “Deed of Trust” (or “Mortgage” in some states), without the open-end language. These are closed-end instruments: one loan, one disbursement, one payoff schedule.
Look at How Your Payment and Interest Behave
How your payment is calculated gives you another strong clue. Most HELOCs carry variable interest rates tied to the prime rate plus a margin set by your lender. If the prime rate is 7.50% and your margin is 1%, your HELOC rate is 8.50%. That rate adjusts, usually monthly or quarterly, and your payment moves with it. Federal law requires every variable-rate HELOC to carry a lifetime cap on how high the rate can go, but within that ceiling the fluctuation can be meaningful.
During the draw period, many HELOCs ask for interest-only payments, so your principal doesn’t shrink. A standard fixed-rate mortgage does the opposite. Every payment chips away at both interest and principal in predictable, equal installments over 15 or 30 years. If your monthly obligation changes with market conditions, or if you’re paying interest only, you almost certainly have a HELOC.
This matters most when the draw period ends. Once the loan enters its repayment phase, you start paying both principal and interest on whatever balance remains, and the payment can jump sharply. A repayment phase typically runs 10 to 20 years. Lenders sometimes call the jump “payment shock,” and it catches people off guard when they didn’t realize they had a HELOC in the first place.
Pull Your Credit Report
Your credit report labels every account by type, and HELOCs and mortgages land in different categories. A HELOC is classified as a revolving account with a credit limit and a fluctuating balance. A conventional mortgage shows up as an installment loan with a fixed original balance and a set schedule of payments. You can check these designations on any of your reports from Equifax, Experian, or TransUnion.

Call Your Servicer if the Paperwork Doesn’t Settle It
When the documents aren’t clear, a phone call will close the question. Use the customer service number on your most recent statement, have your account number ready, and ask directly whether your loan is a revolving line of credit or a closed-end installment loan. The servicer can confirm the loan type in seconds.
While you have them on the line, ask when the draw period expires and whether the loan converts to a fully amortizing repayment schedule or ends with a balloon payment. Federal disclosure rules require HELOC lenders to inform borrowers about balloon payment possibilities up front, but if you inherited the property or weren’t paying close attention at closing, the detail may have slipped by.2Consumer Financial Protection Bureau. 12 CFR 1026.40 Requirements for Home Equity Plans
Why Knowing Which One You Have Matters
Tax Deductions Follow Different Rules
Interest on a conventional home purchase loan is generally deductible when you itemize, subject to a cap on the first $750,000 of mortgage debt ($375,000 if married filing separately). That cap, originally set by the Tax Cuts and Jobs Act, is now permanent.3Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction
HELOC interest follows a stricter rule. It is deductible only if you used the borrowed money to buy, build, or substantially improve the home securing the loan. Pulling $40,000 from a HELOC to renovate your kitchen qualifies, under the same $750,000 combined limit. Using the money to pay off credit cards or fund a vacation does not, and that interest is not deductible at all.4Internal Revenue Service. Real Estate (Taxes, Mortgage Interest, Points, Other Property Expenses) 2 People sometimes deduct all the interest on their Form 1098 without checking whether the funds qualified, and that’s where not knowing you have a HELOC creates problems.
Refinancing and Foreclosure Treat Them Differently
A HELOC almost always sits in second lien position behind your primary mortgage, and that ranking changes two situations.
In a foreclosure, debts are paid in order of lien priority. The first mortgage is paid from the sale proceeds before the HELOC lender sees a dollar. If the home sells for less than the first mortgage balance alone, the HELOC lender gets nothing and the lien is wiped from the title. The debt itself doesn’t disappear; it can survive as unsecured debt the lender may still try to collect.
Refinancing creates a different problem. Paying off your first mortgage through a refinance would normally bump the HELOC into first position, since it becomes the oldest recorded lien. New lenders won’t fund a refinance unless they hold first position, so your HELOC lender has to sign a subordination agreement giving up priority voluntarily. Most will cooperate, but some drag their feet or refuse, and the process can delay a refinance by weeks. If you’re planning to refinance, start the subordination request early.
Your Lender Can Freeze the Line
Only HELOCs carry the risk that the lender suspends your borrowing ability or cuts your credit limit without your consent. Federal regulations allow this under specific conditions, including a significant decline in your home’s value, a material change in your financial circumstances that makes the lender doubt your ability to repay, or your default on a material term of the agreement.5eCFR. 12 CFR 1026.40 Requirements for Home Equity Plans A government action that prevents the lender from charging the agreed rate, or that impairs its security interest, can also trigger a freeze. The unused portion of your line can vanish during a downturn or a job loss, exactly when you might count on it. If you were treating that available balance as an emergency fund, understand that access isn’t guaranteed.
Fees You Might Not Expect
HELOCs can carry ongoing costs that standard mortgages don’t. Annual maintenance or participation fees are common, typically ranging from $0 to $100 depending on the lender. Some HELOCs also charge an early termination fee if you close the line within the first two to five years, often $200 to $500. Check your agreement for these provisions before calling the servicer to close an unneeded line. The cancellation fee may be worth paying, but you should know it’s coming.
