The Quick Read: You fold both loans together by closing one new jumbo first lien on the rental that pays off the old first mortgage and the HELOC, releases both old liens, and sends any leftover proceeds to you, with the loan size capped by the lower of a leverage test on value and a rent-coverage test on the new payment. Nothing literally merges. Two old loans get retired and one new loan takes their place. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
- On a standard rental, cash-out leverage tops out around 75% LTV across most of our wholesale network. Short-term-rental collateral tops out at 70%.
- The HELOC payoff uses up loan proceeds, so a heavily drawn line can leave little or no cash to you.
- A bigger combined balance lowers your rent-coverage ratio, so run that number before you apply.
- The new lender will not close behind an open line. The HELOC is either paid off and closed, or its lender agrees to step back.
- Passing the coverage test does not mean the property produces positive cash flow. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Key Terms Defined
Jumbo loan: a loan larger than the conforming limit for the property’s county and unit count. On a DSCR loan, that limit is a size label rather than a program rule.
HELOC: a home equity line of credit, a revolving line secured by a lien on the property.
Cash-out refinance: a new loan that pays off existing loans and hands you the remaining proceeds.
DSCR: debt service coverage ratio, meaning monthly rent divided by the full monthly obligation (principal, interest, taxes, insurance, and any association dues).
CLTV: combined loan-to-value, the total of all liens divided by the property’s appraised value.
Payoff letter: the lender’s written figure to retire a loan on a set date. It includes interest through that date plus any fees.
Subordination: a junior lienholder agreeing to stay behind a new first lien.
Lien release: the recorded document proving a loan is paid and the lender’s claim on the property is gone.
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.
What Does Folding Both Loans Actually Mean?
It means replacing a two-loan stack with a single first-lien loan. You started with a large first mortgage and a HELOC on the same rental. You end with one loan, one payment, and one lien on record.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. That is why the property’s rent, not your paycheck, drives the review.
Plenty of investors have a first mortgage plus a line they drew down for repairs, a down payment on the next deal, or reserves. Over time, the line becomes a floating-cost loan sitting behind a first lien you may also want to change. Replacing both can simplify the file and clean up the lien position for a later sale or refinance.
The cost of that simplicity is real. You give up the old first mortgage’s terms. If that first lien is cheap, replacing it can raise your carrying cost, and the line you pay off may have been the cheaper money. Lendmire’s piece Keeping the First Lien vs Rolling Both Into One Cash-Out Refinance covers that tradeoff in depth. This article stays on the mechanics.
How Does Underwriting Size the New Loan?
Two tests set the loan size, and the lower result wins. The value test applies a maximum LTV to the appraised value. The rent test asks whether the rent covers the new full payment at the program’s minimum coverage ratio.
The value test comes first. Cash-out refinances top out around 75% LTV on standard rentals across most of the network. On short-term-rental collateral, the cash-out ceiling is 70%. Lenders generally want about 6 months of seasoning, meaning time on title, before a cash-out.
The rent test comes second. Coverage of 1.00 is where select programs start. It is a floor for specific programs, not the standard. Stronger ratios open better pricing and more leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
The HELOC payoff is part of the new loan, so it eats into both tests. The new loan has to cover:
- the old first mortgage payoff,
- the HELOC payoff,
- closing costs and prepaids,
- any prepayment charge on the old first,
- any cash you want to receive.
A Worked Example in Percent of Value
These figures are modeled assumptions, not market data. Both investors hold a standard rental, and both apply for a cash-out at the 75% ceiling.
| Item (% of appraised value) | Investor A | Investor B |
|---|---|---|
| Old first payoff | 55% | 62% |
| HELOC payoff incl. Interest | 12% | 14% |
| Closing costs (modeled) | 2% | 2% |
| Total to cover | 69% | 78% |
| Cash-out ceiling | 75% | 75% |
| Result | Up to ~6% left for cash | ~3% short |
Investor A can take some cash, if the rent test also clears. Investor B cannot finish the deal without bringing cash to closing. The loan is labeled a cash-out, yet it asks for cash in.
Now the rent side. A larger combined balance means a larger payment, so the coverage ratio drops. Say the old first alone covered the rent at roughly 1.30x. The new, bigger loan might land near 1.10x. That still clears a 1.00 start. At 0.95x, the file would need the sub-1.00 path through select lenders, with leverage and terms adjusted.
One caution applies to every ratio here. DSCR compares rent to the monthly payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. Clearing 1.00 is a lender test, not proof the property cash flows.
The Step-by-Step Sequence
Here is the order on a typical file.
1. Request both payoff letters. Ask for the first mortgage payoff and the HELOC payoff. The payoff is higher than your statement balance because it includes interest through the closing date and fees. Also ask the HELOC lender for its closure instructions.
2. Confirm what the HELOC is secured by. If the line is recorded against the subject rental, it must be paid and released. If it is secured by a different property, it is just a debt this loan can repay, and the lien on the other property is handled separately.
3. Check title and vesting. Investment equity lines are generally personal-name products. A DSCR cash-out can often allow LLC title, subject to program eligibility. Do not move title before you check the new lender’s entity rules, because a deed transfer can touch the old first’s due-on-sale clause and your insurance.
4. Order the appraisal with a rent schedule. For investment files, the appraisal includes a rent schedule. The form is the 1007 for single-family or the 1025 for two-to-four units.
5. Size the loan. Apply the value test and the rent test, then add up the sources and uses above.
6. Close. The title company wires the payoffs to both lenders, records the releases, and sends any remainder to you.
7. Read the final settlement statement. Confirm the first and the HELOC both show paid, the line is formally closed, and the new loan sits in first position.
A zero balance on a HELOC does not remove its lien. The recorded claim stays until the line is closed and the release is recorded. Many investors miss this, and it can surface at the next sale or refinance.
Does the HELOC Payoff Count as Cash-Out?
Often it does, and the label affects your leverage and pricing. Agency-style conventions treat a HELOC payoff as cash-out unless the line financed the purchase, such as the second piece of a purchase piggyback. That convention is useful context only. DSCR loans are not agency products, and a given lender may classify the payoff differently.
Ask your broker how the lender treats the payoff before you lock a plan. The answer changes the LTV ceiling that applies. A payoff with no cash to you, a payoff plus cash, and a payoff of a recently drawn line can each be treated differently.
Recent draws deserve a flag. If you drew the line shortly before refinancing, a lender may look harder at where the money went. A line that funded an improvement on this property reads differently from a line that funded a purchase elsewhere. The file should explain the use.
Why Roll a HELOC Into One Jumbo Cash-Out Instead of Keeping It?
Rolling the line in works when you want a single lien and one fixed structure, and the old first is not a bargain you would hate to lose. Keeping the line only works if the first lender and the line lender can coexist on the new loan. Compare the three paths.
| Path | Best when | Watch for |
|---|---|---|
| Keep both loans | The first is cheap and you need nothing | Line stays floating |
| Roll both into one cash-out | You want one lien and one payment | Larger balance, lower coverage |
| Refinance first, keep HELOC | You want a fresh first and to keep the line open | Line lender must agree to stay behind |
The third path rests on the line lender’s consent. A new first lender will not close in second position behind an existing HELOC. The HELOC lender can refuse to subordinate, and Ask CFPB says as much: you may need the HELOC lender’s approval, and if it refuses, you may need to pay the line off. Cash-outs are harder to subordinate than rate-and-term refinances, because the first-lien balance grows. Lenders also tend to test the full credit limit, not just the drawn balance. Payoff removes all of that.
How Does an Investment HELOC Compare to a DSCR Cash-Out?
If you are considering a fresh investment-property line instead of rolling the old one in, the terms differ sharply. Across our wholesale network, an investment-property line is a standalone line in first or second position. These are typical ranges, subject to lender guidelines and full file review.
| Feature | Investment HELOC | DSCR cash-out |
|---|---|---|
| Max leverage | 70% CLTV | ~75% LTV standard rental |
| Size | $25,000 to $500,000 | ~up to $3,000,000 on standard programs (smaller balances available through select lenders) |
| Credit | 700 minimum | ~660 typical, 620 in parts |
| Title | Individual or revocable trust | LLC possible, per program |
| Structure | 5-year draw, 25-year repayment, floating | 30-year fixed spine |
Investment lines require a 700 minimum score, at least 75% of the line drawn at closing, and pricing that floats through the draw and repayment periods without converting to fixed. LLCs, corporations, and partnerships cannot hold title. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead. The line is also offered in a narrower set of states than the DSCR footprint, so confirm availability early. For a rental held in an LLC, a DSCR cash-out is usually the cleaner vehicle, subject to program terms.
Where the General Rule Breaks
A few situations change the playbook.
A small HELOC balance. Rolling a modest balance into a much larger loan raises the new balance and trims your coverage ratio for little benefit. Paying it from cash on hand can be cleaner. Run both versions.
A large undrawn line. An unused limit does not need to be paid, but it must be closed and released if the loan is to take first position. Closing it means giving up access to that credit. Investors sometimes forget that they lose the line.
A property that was once your home. A former primary residence now rented may still carry features tied to personal-use credit. Business-purpose treatment generally applies to credit for acquiring, improving, or maintaining non-owner-occupied rental property, and the Federal Reserve’s Regulation Z commentary on Cornell Law’s site notes the treatment can change if you expect to occupy the property yourself. Because a property with a history of personal use may be treated differently from a pure rental, have counsel review any mixed-use history.
A DSCR first followed by a HELOC. If the DSCR loan comes first and you add a line later, the note may restrict additional liens. Read the note before you plan on it.
Ineligible property types. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through the network’s DSCR programs. Folding loans together will not fix eligibility.
Short-term rentals. Expect a 640+ score and roughly 12 months of hosting history, and note the 70% cash-out ceiling for short-term-rental collateral. Short-term rental rules vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Thin rent coverage. Where coverage lands below 1.00, available paths run through select lenders in the network, with leverage and terms adjusted. Extended terms, such as a 40-year structure or an interest-only period, are also available through select lenders, and they can lift coverage by trimming the payment.
What Does “Jumbo” Change Here?
It changes size and reserves, not the basic method. The Federal Housing Finance Agency sets the conforming limit by county and unit count, and its announcement of conforming loan limits puts the one-unit baseline at $832,750. A loan above the limit for your county is jumbo. That is a classification. A DSCR loan is not an agency product, so the limit is context, not a program rule.
What matters in practice:
- Loan size. Standard DSCR loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.
- Reserves. Reserves vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA (principal, interest, taxes, insurance, and association dues) is common. Loans above $1,500,000 typically step up to about 9 months.
- Credit. A 620 floor exists in parts of the network, and most programs want around 660. A 700+ profile unlocks the strongest leverage tiers.
- Appraisal. Expect a full appraisal with a rent schedule on a loan this size.
Because the combined payoff is larger than a typical loan, the stack of reserves, appraisal, and coverage all matter at once. A bigger down payment or lower balance can lift coverage, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Lendmire’s complete DSCR loans guide covers how the ratio works from the ground up.
The Decision in Practice
The core question is whether simplicity beats what you give up. Work through four checks before applying.
1. Equity. Add the first payoff, HELOC payoff, and costs as a percent of value. Is the total under the leverage ceiling with room left?
2. Coverage. Does rent cover the new, larger payment at or above the program’s starting ratio?
3. Legacy terms. Compare your current combined payment to the new one. If you would keep a low-cost first, consider refinancing only the line.
4. Purpose. Know what the cash is for. Tax treatment can depend on how the funds are used and how the property is held. Keep clear records and speak with a qualified tax professional before relying on any deduction.
This path is not for an investor who needs maximum cash out from a thinly equitied rental, who holds a first lien they would be glad to keep, or who plans to sell soon. Closing costs take time to earn back. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
An experienced broker sees one pattern repeatedly. Files fail not on the loan concept but on the payoff stack, where the HELOC payoff plus costs pushes the total just over the leverage ceiling. Running the sources-and-uses math before the appraisal saves surprises.
Frequently Asked Questions
Can I combine a HELOC and a jumbo first mortgage into one loan?
You can replace both with one new first-lien loan. The new loan pays off the first and the HELOC, and the old liens are released. Eligibility depends on appraised value, rent coverage, credit, reserves, and property type, subject to lender guidelines.
Will the HELOC payoff count as cash-out?
Often it does, and that classification can affect leverage. Under agency conventions, a HELOC payoff is typically cash-out unless the line financed the purchase. DSCR lenders may treat it differently, so ask how your lender classifies it.
What happens to my HELOC at closing?
The title company wires the payoff to the HELOC lender, and the line is closed. The lender then records a release. A zero balance alone does not remove the lien, so confirm closure and release on the settlement statement.
What if I cannot get enough cash out?
The HELOC payoff, closing costs, and any prepayment charge all come out of proceeds first. When the total approaches the leverage ceiling, little or no cash remains. Options include paying down the line before closing, keeping the first and refinancing only the line, or bringing cash to closing.
Is a lower payment guaranteed?
No. The new loan is larger than the first alone, and the line is gone, so your combined obligation can go up or down. Compare your current two payments to the new one before you commit.
If you are weighing a home equity line against a cash-out refinance and want to see how the numbers work, Lendmire can help you compare options based on the property, the equity available, credit profile, combined leverage, and your goals. Lendmire brokers DSCR investor loans through select lenders in its wholesale network across 41 markets, including Washington, D.C.; it is not the lender, and nothing here is a commitment to lend. The calculator on this site gives an illustrative estimate only.
The deal that survives a payoff stack is the one where the equity, the rent, and the old first’s terms all still make sense once the HELOC comes out of the middle.
