The Quick Read: A cash-out refinance does not adjust a variable home equity line; it ends the line, pays it off from the proceeds of a new first-lien loan, and replaces its floating payment with one term-loan payment on a larger balance. On a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, that new payment gets tested against the rent.
- The old floating payment disappears. A fixed-rate, fully amortizing payment on the whole new balance takes its place.
- Nothing is merged. Two old liens are paid off, and one new lien is created.
- The new payment is usually larger in total, because it covers principal on the entire balance, not just interest on the drawn part of the line.
- Most standard-rental cash-out refinances in the network top out around 75% LTV, so the combined payoff has to fit under the value.
- Clearing a DSCR test is not the same as positive cash flow.
Why a Variable HELOC Payment Moves
A variable HELOC payment moves because the line’s rate has two parts. One is an index, such as the U.S. prime rate. The other is a margin, a fixed percentage the lender adds on top. The margin stays put, so the payment changes whenever the index changes.
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 payment also depends on which phase the line is in. According to Yahoo Finance, a typical line has a draw period of about 10 years followed by a repayment period of about 20. During the draw, the interest-only payment is the drawn balance times the annual rate, divided by 12. That works out to a small number compared with a full payment, which is why a line feels cheap early on.
Two things are worth noticing. The payment tracks what you have drawn, not the credit limit. And an interest-only payment never shrinks the debt. The balance you carry out of the draw period is the balance you carry into repayment, and the same article notes that payments can rise sharply once repayment begins.
That step-up is the usual reason investors start looking at a cash-out refinance in the first place. The floating payment is hard to forecast, and the cliff at the end of the draw period is easy to underestimate.
Key Terms Defined
Draw period: the opening stretch of a HELOC when you can borrow against the line and usually pay only interest.
Repayment period: the later stretch when you can no longer draw and the payment includes principal as well as interest.
Index and margin: the two parts of a variable rate. The index moves with the market, and the margin is the lender’s fixed add-on.
Lien: a lender’s recorded claim on the property. A first lien gets paid before a second lien if the property is sold or foreclosed.
Subordination: a signed agreement in which a junior lienholder, such as a HELOC lender, agrees to stay behind a new first lien.
DSCR: the debt service coverage ratio, meaning monthly rent divided by the full monthly housing payment.
PITIA: principal, interest, taxes, insurance, and association dues. It is the full monthly obligation the rent is measured against.
CLTV: combined loan-to-value, which adds every loan on the property together and divides by the property’s value.
Seasoning: the waiting period a lender wants between events, such as buying a property and pulling cash out of it.
What Actually Happens to the Old Payment
Here is the sequence on a typical file, step by step.
1. Payoff statements are ordered for every lien, including the HELOC. The payoff figure is not the drawn balance. It includes interest through the closing date plus any fees, and a daily amount keeps accruing if closing slips.
2. Lien priority forces a decision. Once the old first mortgage is paid off, the HELOC would move up into first position by recording order. A new first-lien lender will not accept sitting in second place. So the HELOC is either paid off or its lender signs a subordination agreement.
3. The HELOC lender has no duty to subordinate. It can refuse. Subordination also gets harder on a cash-out, because the first-lien balance is growing. That is why most investors let the new loan pay the line off.
4. The payoff comes out of the new loan’s proceeds. Cash to you is the new loan minus the lien payoffs and closing costs.
5. The line must be formally closed. A zero balance does not remove the lien. The line stays recorded until it is closed and the release is recorded. Get the closure in writing and confirm the release, because an unclosed line can leave a second lien sitting on the property.
6. The new payment is underwritten. On a DSCR file, the lender divides monthly rent by PITIA.
The documents are predictable. Expect payoff statements for every lien, the HELOC note and a recent statement, title work showing all liens, and a subordination agreement only if the line stays open.
One misconception is worth clearing up here. People say the refinance merges the HELOC into the mortgage. It does not. The old payment does not get absorbed, because the loan that produced it no longer exists.
How the New Payment Gets Tested
The new payment is a term-loan payment on the whole combined balance. Across the wholesale network Lendmire places files with, the spine of the product is the 30-year fixed. Select lenders in the network also offer 40-year terms and interest-only periods. ARM structures exist for investors who want them. Above $2,500,000, the network generally holds to 30-year fixed structures.
The lender then asks whether the rent covers the payment. That is the DSCR test. Many select programs start at a 1.00 coverage ratio, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Eligibility turns on lender guidelines, credit profile, reserves, and property review. Details of the whole program are laid out in Lendmire’s complete DSCR loans guide.
The rest of the typical profile looks like this:
- Leverage: a standard-rental cash-out refinance tops out around 75% LTV across most of the network.
- Seasoning: about 6 months of ownership is the common expectation.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).
- Reserves: commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Loans above $1,500,000 typically step up to about 9 months.
All of that is subject to lender guidelines and full file review, and none of it is a commitment to lend.
Here is the catch that surprises people. A cash-out raises the balance, a bigger balance raises the payment, and a bigger payment lowers the coverage ratio. A longer amortization can pull the ratio back up. And clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.
Does the Payment Go Up or Down?
It depends on four things: the size of the combined balance, the length of the new term, whether the old first mortgage was a low-cost loan, and how much cash you take out beyond the payoff. The comparison below shows how the two structures differ.
| Factor | Variable HELOC | New cash-out first lien |
|---|---|---|
| Payment basis | Interest on the drawn balance | Principal and interest on full balance |
| Moves with the market? | Yes, through the index | Usually no, if fixed |
| Phase change | Step-up at repayment | None |
| What is tested | Your DTI and credit | Rent against PITIA |
| What gets repriced | Only the line | The entire first-lien balance |
That last row matters most. A cash-out reprices the whole first-lien balance, not just the HELOC piece. If the old first mortgage is a low-cost loan, folding it into the new one can cost more than the HELOC fix saves. A low first mortgage usually argues for leaving it alone and addressing the line some other way.
Think of a rental with a modest first mortgage and a HELOC that is about to leave its draw period. The floating payment is about to step up, and the investor wants predictability. A cash-out replaces both loans with one, which gives a steadier payment but exposes the whole balance to new terms. This one is a genuine tradeoff. The predictability is real, and so is the cost of giving up the low first.
The investor strategy known as recycling the HELOC works the same way. You use the line to fund a purchase and renovation, then refinance and pay the line off. The risk is that the refinance may not return the full amount you drew, which leaves part of the HELOC tied up. Sizing the line against what the refinance can actually return is the whole game.
Hold period matters too. Closing costs take time to pay back. A short hold favors keeping the line, and a long hold favors the fixed structure.
For a deeper side-by-side, Lendmire’s article Variable HELOC vs Fixed Cash-Out on a Rental You Won’t Refinance covers the choice when the loan is a long-term keeper.
Where the General Rule Breaks
The standard story is that the HELOC is paid off and the payment becomes fixed. These cases bend it.
Subordination refused. Paying the line off inside the new loan removes the need for the junior lender’s consent. The new loan still has to fit the value test and the rent test.
No cash comes back. A payoff-only loan is generally still a cash-out by structure, because the new loan is larger than the old first. Some programs may treat it as a limited cash-out, depending on where the closing money goes and whether the line was drawn recently. That line is drawn by lender policy and differs from one lender to the next.
The HELOC sits on a different property. It may stay open. It may still need subordination if it touches the subject property.
An unused line. An old, untouched line still counts as a lien that has to be handled.
A prepayment charge on the old first. If the old first mortgage is itself a DSCR loan, check its prepayment clause before you start. That clause can change the math entirely.
Teaser rates and caps. The CFPB’s HELOC brochure describes introductory discount rates, caps, and floors. That means the payment you are replacing may have been artificially low or capped. Compare the new payment against what the line would cost at full pricing, not the teaser.
Title and entity. Investment-property HELOCs generally require title in your personal name or a revocable trust. A rental deeded to an LLC points toward a DSCR cash-out instead, subject to program terms.
Replacing the Line With Another Line
Some investors ask whether they should just swap the HELOC for a new HELOC. Sometimes that works, but the network’s investment-property lines come with firm limits. They cap at 70% CLTV on an investment property, with a 700 minimum credit score and a $500,000 maximum line. There is no tier above that on investment properties.
The structure is also fixed. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats across both the draw and the repayment period and never converts to fixed. So a new line does not remove the variable-payment problem.
Qualification is different as well. A HELOC is underwritten on your debt-to-income ratio, with a 50% maximum, and it is qualified on the interest-only payment calculated on the maximum draw. A DSCR cash-out looks primarily at the rent. Investors who already carry heavy personal debt sometimes find that refinancing into a DSCR loan steps around a DTI wall.
Availability is narrower, too. HELOC programs through the network run only in 16 full-service states, while the DSCR footprint spans 41 markets, including Washington, D.C. Manufactured homes, log homes, and barndominiums are not offered under either product.
The Investor Decision in Practice
Work through it in this order.
1. Get the actual payoff figures. Order statements for every lien and add them up. Do not rely on balances shown on an app.
2. Compare the combined payoff against value. A payoff near the 75% LTV ceiling on a standard-rental cash-out leaves little room for cash back or closing costs.
3. Run the rent against the new PITIA. A ratio comfortably above 1.00 gives the file more options, while one near or under it narrows them. Sub-1.00 paths exist through select lenders in the network, with leverage and terms adjusted.
4. Check the old first for a prepayment charge and a low-cost balance. If either one is present, price the alternative of leaving it alone.
5. Decide how the line closes. Plan for the payoff, the written closure, and the recorded release.
6. Estimate how long you will hold the property. A longer hold gives closing costs time to pay back. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Does a cash-out refinance end my HELOC?
Usually it does, because the new first lien has to be in first position. The proceeds pay off the old first mortgage and the HELOC, and both old liens are released. The alternative is a subordination agreement from the HELOC lender, which that lender has no duty to give. Confirm in writing that the line was closed and the release was recorded.
Will my monthly payment go down after the refinance?
It can go either way. The floating interest-only payment is replaced by a principal-and-interest payment on a larger balance, so the total often rises. A longer term can pull it back down. The more useful comparison is old combined payments against the new single payment, plus what happens to coverage.
What if I do not take any cash out?
A payoff-only loan is generally still treated as a cash-out, because the new loan is larger than the old first mortgage. Some programs have a limited cash-out treatment that depends on where the closing money goes and whether the line was drawn recently. Lender policy decides, so ask before assuming.
Can I keep the HELOC and just refinance the first mortgage?
Sometimes. The HELOC lender would need to sign a subordination agreement, and it can refuse. That is harder on a cash-out because the first-lien balance grows. If the line is on a different property, it may stay open without any change.
Can an LLC-owned rental carry a HELOC?
Generally not. Investment-property HELOCs require title in your name or a revocable living trust, and LLCs cannot hold title. A rental already in an LLC points toward a DSCR cash-out, subject to lender program eligibility.
