The Quick Read: Refinancing a balance into a new HELOC on a rental means opening a fresh line that pays off the old one, and that line must meet investment standards of a 700 credit score, up to 70% combined leverage, a $500,000 maximum, and title held personally or in a revocable trust. The line is underwritten on you, not on the rent. Every figure below is subject to lender guidelines and a full file review.
- Credit: 700 is a hard floor on an investment line, and a higher score buys eligibility rather than extra leverage.
- Leverage: The ceiling is 70% combined loan-to-value (CLTV) on an investment property, counting every lien including the new line.
- Size: Lines run from $25,000 to $500,000, and you must draw at least 75% of the line at closing.
- Title: An LLC cannot hold title on this product, so a rental deeded to an entity needs a different route.
- Pricing: It floats through both the draw and repayment periods and never converts to fixed.
What “Refinancing a Balance Into a New HELOC” Actually Means
Refinancing a HELOC is not a modification. The new lender opens a separate account, pays the old balance off at closing, and starts a new draw period with new terms. Nothing carries over from the old line except the property.
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.
That matters because the new line is underwritten as a brand-new request. It does not matter that the old line already existed, that you made every payment, or that the balance is small. Credit, leverage, debt load, title, and property type are all tested again.
Three starting situations show up most often on rentals:
| Starting point | What the new line does | What stays in place |
|---|---|---|
| First mortgage only | Adds a line behind it | The first mortgage |
| First mortgage plus old HELOC | Pays off old HELOC, takes its place | The first mortgage |
| Free and clear plus old HELOC | Pays off old HELOC, can sit in first position | Nothing |
Lendmire’s wholesale network treats the new line as a standalone loan in first or second lien position. The exact payoff and lien-release mechanics are set by the lender that takes the file.
The Requirements at a Glance
Investment-property lines are harder to get than lines on a home you live in. NerdWallet reports that lenders see higher default risk and that fewer lenders offer them at all. Across the select lenders in Lendmire’s network, the picture is tighter and more specific:
| Requirement | Investment line in the network |
|---|---|
| Minimum credit | 700, single-bureau score |
| Max combined leverage | 70% CLTV |
| Line size | $25,000 to $500,000 |
| DTI | 50% maximum |
| Draw and repayment | 5-year interest-only, 25-year repayment |
| Drawn at closing | At least 75% of the line |
| Valuation | Automated model, usually |
| Title | Individual or revocable living trust |
Credit at 720 or higher lands in the same 70% tier as 700. Investment is a two-tier table, and both tiers cap at the same leverage. A 780 score does not get you a bigger line than a 700.
Pricing floats for the life of the line. Some lines elsewhere let you convert part of the balance to a fixed rate. The federal consumer regulator’s HELOC page notes that some plans allow it. This investment line does not.
How Underwriting Treats the Refinance, Step by Step
Here is the sequence a lender follows. Knowing it lets you fix problems before they cost you a denial.
Step 1: List every lien on the rental. That means the first mortgage, the old HELOC’s drawn balance, and anything else recorded against the property. CLTV counts all of it, plus the new line.
Step 2: Size the line. The lender takes the property value times the 70% cap, then subtracts what stays in place behind the new line. The result is compared with the $500,000 maximum, and you get the smaller number. If the old HELOC is being paid off, it does not count against the room, because the new line replaces it.
Step 3: Pull credit. The network uses a single-bureau score tied to the primary wage earner. The report can be no more than 90 days old at closing, and there are no rescores. On most files in the five-year-draw program, you also need two tradelines seasoned 12 months, or one seasoned 24. Housing history is tested across all financed properties, not just this one.
Step 4: Run DTI. The lender qualifies the payment on the interest-only amount for the maximum draw, not on your current balance. A small drawn balance does not shrink the test. Rent does not lift the file here, because the line is underwritten on you.
Step 5: Set the value. Because an investment line tops out at $500,000, and full appraisals begin only above $500,000, valuation is ordinarily an automated model. A higher CLTV may call for a secondary valuation, and you can ask for a full appraisal in any case.
Step 6: Check title and property. Vesting and property type are tested at this stage, and they can end a file that cleared everything above.
Step 7: Close and draw. The initial draw funds at closing. It pays off the old line first, and any remainder goes to you. The new draw clock then starts.
A Worked Example, in Percentages
Say a rental is worth 100 units of value. The numbers below are modeled assumptions, not market data.
- The first mortgage is 45% of value.
- The old HELOC balance is 15% of value.
- Combined debt today is 60%.
The CLTV cap is 70%, so the new line can reach 25% of value (70% minus the 45% first mortgage). Assume the line is at or below the $500,000 maximum.
At least 75% of that line must be drawn at closing. That is 18.75% of value. The old HELOC payoff takes 15%, so 3.75% of value comes to you in cash, and 6.25% stays available to draw later. The lender will usually want the draw to cover the payoff first.
Now stress it. Say the first mortgage is 55% and the old HELOC is 15%, so you are already at 70%. The new line is capped at 15% of value, which exactly covers the payoff. You get no new cash and no available credit. You have swapped one line for another.
Now push it over. If combined debt is 75% before you start, the payoff alone does not fit, and the file does not work unless you pay down debt first.
One point catches people. The 75% initial draw is a minimum, not a choice. If your payoff is small and the line is large, you still draw the required share and start paying interest on all of it.
Structure and Variations That Exist
An investment line in the network runs one structure: a five-year interest-only draw followed by a 25-year fully amortizing repayment, with a 30-year maturity. This is the five-year-draw program. After closing, later draws carry a $1,000 minimum on that program.
A second program in the network, the three-year-draw program, offers a three-year draw with a 17-year repayment and higher leverage. That structure applies only to primary residences and second homes. It does not apply to investment lines. A quoted CLTV always carries its own program’s structure, so never compare a primary-home quote to a rental quote.
Other structural facts to know:
- Lien position: First or second, depending on what stays in place. A free-and-clear rental can carry a first-lien line.
- Number of lines: A borrower is limited to three lines. Combined exposure caps at $750,000 on the five-year-draw program.
- Portfolio size: A borrower owning more than 15 financed properties is not eligible.
- Each line is secured by one property: Equity in one rental cannot support a line on another.
Variable pricing deserves a real look on a rental. The federal HELOC booklet says HELOCs typically carry variable rather than fixed pricing. When the index rises, your interest-only payment rises while your rent stays put. Many investors stress their own cash flow at a much higher payment before they sign.
Where the General Rule Breaks
Most of the surprises on these files come from the same few edge cases.
An LLC holds title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this product. This is the sharpest difference from a DSCR loan. A rental already deeded to an entity needs a vesting change, or a DSCR cash-out refinance instead.
Credit is below 700. No investment line is available. The two practical paths are raising the score or using a DSCR cash-out.
DTI is above 50%. The file does not move. Pay down debt and reapply, or look at a rent-based loan.
The property is listed for sale. In six of the 16 states the network serves (IN, NC, PA, TN, TX, WA), a property listed for sale, or listed within the past 60 days, is ineligible.
The property type is not eligible. Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
There is derogatory credit. A bankruptcy needs four years of seasoning from discharge or dismissal. Investment files follow a seven-year path for foreclosure and four years for a deed-in-lieu, pre-foreclosure, or short sale.
The rental is outside the footprint. The HELOC is available in 16 states, based on where the property sits. That is narrower than the 41-market DSCR footprint, so a rental in a covered DSCR market may still fall outside the HELOC states.
You want a bigger line. Lines above $500,000 exist only on a primary residence, so they are not a path for a rental.
If a bank has told you no because the property is a rental, you are not alone. Market commentary, including a BiggerPockets author who describes refinancing a HELOC to raise its limit, shows that lender appetite varies widely. A broker sees many lenders’ guidelines side by side, so a no from one bank often says little about the rest of the market.
Should You Roll It Into a New Line?
There is no universal answer, and the stronger play depends on how long you plan to hold the debt. A line suits a short hold, such as a renovate-and-stabilize plan that gets refinanced into a fixed-term loan later. It suits a long hold less well, because floating pricing and a draw period that ends are structural risks.
Rolling into a new line also resets the clock. You restart a five-year interest-only runway, which delays principal payments. That feels good for cash flow and can quietly extend the debt for years.
| Option | Reviewed on | Keeps first mortgage? | Best fit |
|---|---|---|---|
| New HELOC | Your credit, DTI, equity | Yes | Short hold, keep a good first loan |
| Keep the old line | Already in place | Yes | Draw period still has runway |
| DSCR cash-out refinance | Rent covering the payment | No, replaces it | Entity-held or larger equity needs |
| Fixed-term refinance | Varies by program | No, replaces it | Long hold, stable payment |
A cash-out refinance replaces the first mortgage. A HELOC leaves it alone. If the first mortgage is a loan you want to keep, that single fact can decide the question.
The DSCR route works differently. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across the network, a DSCR cash-out on a standard rental tops out around 75% LTV, with about six months of seasoning commonly expected. Select programs start at a 1.00 coverage ratio. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and credit floors start at 620 in parts of the network. Most programs want around 660, and 700 or better opens the strongest tiers. LLC-held rentals can use this route, subject to lender program eligibility. Reserves commonly run around six months of PITIA, though they vary by lender, leverage, and loan size.
Clearing 1.00 is not the same as positive cash flow. The coverage ratio compares rent to principal, interest, taxes, insurance, and HOA dues. It ignores repairs, vacancy, management, and utilities.
The complete DSCR loans guide lays out how that rent-based path compares with a line of credit.
Key Terms Defined
CLTV (combined loan-to-value): All loans secured by the property, including the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line and pay interest only. On an investment line here, it lasts five years.
Repayment period: The stretch after the draw period ends, when you pay principal and interest. On an investment line here, it lasts 25 years.
Lien position: Where a loan stands in line for repayment if the property is sold. A first lien is paid before a second.
DTI (debt-to-income): Your monthly debt payments divided by your monthly income. This line allows up to 50%.
Automated valuation: A computer model that estimates value without an appraiser visiting the property.
Vesting: The legal name on the title. On this product, it must be you or your revocable living trust.
DSCR: The debt service coverage ratio, which compares a property’s rent to its full monthly obligation.
Frequently Asked Questions
Does a new HELOC restart the draw period?
Yes. A new line is a new account, so the draw clock starts over at closing. On an investment line in the network, that means a fresh five-year interest-only draw followed by a 25-year repayment. The restart delays principal repayment, which helps cash flow now and extends the debt later.
Can I refinance an investment HELOC if the property is in an LLC?
Not on this product. Title must sit with you personally or in a revocable living trust. If the rental is deeded to an entity, you would need to re-vest title or use a DSCR cash-out refinance, which can accept entity-held rentals subject to program terms.
Does rental income help me qualify?
No. The line is underwritten on your credit, DTI, and equity, not on what the property rents for. Property-rent-based lender review is what a DSCR loan does. On a HELOC, a strong rent roll cannot offset a score below 700 or a DTI above 50%.
Will the lender order a full appraisal?
Usually not. Because an investment line caps at $500,000 and full appraisals start above that, valuation is ordinarily an automated model. A higher CLTV may require a secondary valuation, and you can request a full appraisal.
What if my old HELOC plus my first mortgage already exceed 70%?
The file does not work as submitted. Because the old HELOC is paid off, only what remains behind the new line counts against the cap. If your combined debt is still above 70% of value, paying down the balance or choosing a DSCR cash-out with different leverage rules are the usual fixes.
