The Quick Read: No. A home equity loan or HELOC is a separate loan with its own note, its own payment, and its own maturity, so it is not due when the mortgage is due. Both loans sit on the same property, which means they get settled together only at a payoff event such as a sale, a refinance of the first mortgage, or a default.
- You make two payments: one on the mortgage, one on the equity product.
- A home equity loan is a lump sum. A HELOC is a revolving line with a draw period and then repayment.
- Paying off or refinancing the first mortgage does not pay off the second lien.
- A sale clears every lien at closing, first mortgage first.
- On a rental, a second lien has to be paid off, rolled in, or subordinated before a new first loan can sit ahead of it.
Are They Separate Loans With Separate Payments?
Yes. A home equity loan or HELOC does not change the terms of your first mortgage. Each one is its own contract with its own servicer and due date.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
The Consumer Financial Protection Bureau explains that if you already have a mortgage, either product is a second mortgage that you pay in addition to the first. A home equity loan is a lump sum. A HELOC is a revolving line you can draw on repeatedly.
The loans are tied together by the collateral, not by the payment schedule. Both are secured by the same house. The second one is a junior lien, meaning it ranks behind the first in priority. If the property is foreclosed, the first-mortgage holder is paid before the second.
That is the whole relationship. Same house, two debts, two sets of terms.
Key Terms Defined
- Second mortgage: any loan secured by a house that already has another loan secured by it. Home equity loans and HELOCs both count.
- Junior lien: a lien that ranks behind another one in priority of repayment.
- Draw period: the stretch of a HELOC when you can borrow against the line.
- Subordination: a written agreement by the second-lien holder to stay behind a new first loan.
- Piggyback loan: a home equity loan or HELOC made at the same time as the main mortgage, often to avoid mortgage insurance on a low down payment. The federal consumer-finance regulator’s piggyback explainer covers it. The two loans close together but remain separate notes.
How the Payments Work Month to Month
You pay each loan to its own servicer. Missing one payment does not automatically show up as a missed payment on the other, but both liens are on the same property, so trouble on either one is a real risk to the house.
| Feature | Home equity loan | HELOC |
|---|---|---|
| Funds | Lump sum at closing | Revolving line |
| Payment structure | Set repayment schedule | Draw period, then repayment |
| Payment change | Stays on its schedule | Rises when repayment begins |
| Relation to first mortgage | Separate note | Separate note |
The part that catches people is the HELOC’s change at the end of the draw period. The federal consumer-finance regulator’s HELOC materials describe a borrowing period followed by repayment, and lenders must disclose the length of both periods and the fees when you apply. The shift to repayment is a payment increase. How large depends on your balance and contract, so read the agreement before you draw. Some plans may also end with a balloon payment.
When Is the Balance Due? A Timeline
Two readings of the question exist. One is “will I owe a separate payment every month?” Yes. The other is “does the balance come due when something happens to the mortgage?” That depends on the event.
| Event | Home equity loan | HELOC |
|---|---|---|
| Scheduled payments | Paid on its own schedule | Paid on its own schedule |
| Mortgage paid off on time | Stays open | Stays open |
| Sale of the home | Paid at closing | Paid at closing, line closed |
| Refinance of the first | Paid off, rolled in, or subordinated | Paid off, rolled in, or subordinated |
| Default | Junior lien, paid after the first | Junior lien, paid after the first |
Paying off the first mortgage does not touch the second. The equity loan keeps its own terms and its own payoff date.
What Happens to the Second Loan When You Sell
Every lien has to be cleared before title transfers. The closing agent requests a payoff statement from each lender, and the proceeds go out in order of priority.
1. The first mortgage is paid.
2. The home equity loan or HELOC is paid.
3. Whatever is left goes to the seller.
Two practical points. First, the payoff amount is not the same as the statement balance, because interest through closing and any fees change the number. Second, a HELOC usually needs a written closure request so the lien is released, not just paid down. A line that is paid to zero but never closed can leave a lien on record.
If sale proceeds do not cover both loans, the seller has to bring cash or negotiate a short sale with the lenders. And a HELOC does not move to your next house. It is secured by the property you are selling.
What Happens When You Refinance the First Mortgage
This is where investors get surprised. Refinancing the first mortgage does not pay off the second lien. The second lien has three possible outcomes.
1. Pay it off. The new loan or your own cash clears it.
2. Roll it in. The new first loan is sized to include the old balance.
3. Subordinate it. The second-lien holder signs a written agreement to stay behind the new first loan, and the agreement is recorded with the refinance.
Without one of those, the order flips. Lien priority generally follows recording date, so when the old first mortgage is paid off, an older HELOC lien can move up to first position and the new loan lands behind it. New first lenders do not accept that.
Nothing forces the junior lender to subordinate. It can refuse, and then the refinance has to be restructured around a payoff. That matters if you planned to leave the line mostly unused.
The CFPB’s HELOC page says a HELOC can affect your ability to refinance the first mortgage and you may need the HELOC lender’s approval. Plan for it before you apply, not after the appraisal comes back.
Do You Need Your Mortgage Lender’s Permission?
The second loan can come from the same lender or a different one. Check your own mortgage contract for any terms that restrict additional liens on the property. What is clear is that the equity lender will look at your existing mortgage balance when sizing its loan, because it is stepping in behind it.
The same mechanics apply if you own the home free and clear. “Second mortgage” is an industry label, and a loan on a paid-off house may take first-lien position.
What the Investor Decision Looks Like
For a rental owner, the second lien is a file item, not a footnote. Three situations come up most.
A line on the rental you want to cash out. Say you plan a cash-out refinance on a rental that already carries a HELOC. That line has to be paid off, rolled in, or subordinated. Across Lendmire’s wholesale network, cash-out refinances on investment property top out around 75% LTV on most files, with about 6 months of seasoning the common expectation, so the second lien eats into the same leverage the new loan is trying to use. Combined debt counts, subject to lender guidelines.
A line on your primary home used to buy rentals. Investors do this for a down payment or rehab, then plan a cash-out refinance on the rental to repay the line. The risk is the extra lien on your own residence sitting there until that refinance happens. If the refinance underwrites lighter than planned, the line stays.
A line secured by the rental itself. Equity lines on investment property are harder to find than lines on a primary residence, and terms are generally tighter. For this reason many investors end up using a DSCR cash-out refinance instead. DSCR loans are designed for non-owner-occupied investment properties, and they qualify primarily on property-level rental income covering the payment, subject to lender guidelines.
On the DSCR side, the numbers that matter for a file with a prior second lien are these. Purchases on most files land at 75%-80% LTV. A coverage ratio of 1.00 is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Credit floors start at 620 in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA. Clearing 1.00 is not the same as positive cash flow, since repairs, vacancy, and management sit outside the calculation.
Lendmire’s complete DSCR loans guide walks through how those pieces fit together. For a comparison of the two equity products on a first mortgage you plan to keep, see Lendmire’s piece HELOC vs. Home Equity Loan for a Homeowner Keeping Their First Mortgage.
A quick note on equity lines through Lendmire’s network, for owners who want one: ceilings depend on occupancy. On an investment property the ceiling is 70% CLTV, and the credit floor is 700. On primary residences and second homes, ceilings run higher, and the top tier requires a 720 credit profile. Those lines are limited to Lendmire’s 16 full-service states, and every figure is subject to lender guidelines and full file review.
What If You Can’t Afford Both Payments?
Act before either loan goes late. Contact each servicer, because modification and hardship options are set by the individual lender. A refinance that consolidates the debt is one route, though it depends on equity, credit, and combined leverage. Because the second lender is junior, a foreclosure pays the first mortgage before it pays the second, which is why second lenders watch the first loan’s status closely.
Which Situation Are You In?
- Planning to sell: request payoff statements early and ask each lender what the closure process is for the line.
- Planning to refinance the first mortgage: ask the second-lien holder about subordination before you apply.
- Struggling with payments: call both servicers now, not after a missed due date.
- Wanting to pay off early: check the contract for early-closure penalties. Terms are lender-specific.

Frequently Asked Questions
Is a HELOC part of my mortgage payment?
No. It is a separate loan with its own payment, servicer, and due date. The CFPB classifies both a home equity loan and a HELOC as a second mortgage paid in addition to the first.
Do I have to pay off a HELOC when I sell my house?
Yes. Every lien must be cleared before title transfers. The closing agent collects payoff statements, pays the first mortgage, then the HELOC, and the seller receives what is left. Ask the lender to close the line in writing so the lien is released.
Does refinancing my mortgage pay off my home equity loan?
No. The second lien stays unless it is paid off or rolled into the new loan. Otherwise the holder has to agree in writing to subordinate, and it can decline.
Is a home equity loan a second mortgage?
Yes. A home equity loan and a HELOC are both second mortgages when you already have a first, and both are junior liens behind it. On a home owned free and clear, the loan may sit in first position.
What happens to my HELOC payment when the draw period ends?
The line moves into repayment and the payment generally rises. The size of the increase depends on your balance and contract, so read the disclosure you received at application.
