The Quick Read: The best program for your file is the one that fits your credit, your title, your combined leverage, and your lien order. A new line pays off the old balance at closing, the old line closes, and a fresh draw period starts. That reset fixes a deadline. It does not fix the debt.
- Investment lines on our wholesale network cap at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit profile.
- Title must sit with you personally or in a revocable living trust. An LLC cannot hold it.
- At least 75% of the line is drawn at closing, so size it to the payoff.
- The new line restarts a 5-year interest-only draw, then a 25-year repayment. Pricing floats the whole way.
- If the rental sits in an LLC or the numbers do not fit, a DSCR cash-out refinance is the usual fallback.
What Does “Refinancing a Balance Into a New HELOC” Mean?
You borrow on a new line, use the money to pay off the old line, and the old line closes. Nothing more exotic than that. Lenders call it a payoff and replace, because a home equity line cannot be “converted” into another lender’s line.
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.
A HELOC is an open-end line of credit secured by property equity. You draw during a set period, then repay. The CFPB’s HELOC explainer notes that repayment often runs over ten or 20 years, and that some plans require an initial draw or a minimum balance. Equity is simply value minus what you owe.
Investors usually do this move for one of four reasons:
- The old draw period is ending and the payment is about to change.
- The old lender froze or shrank the line.
- The investor wants a new lender with a clearer path to more equity.
- The old line is on a different lien position than the investor wants going forward.
One investor guide, RentalRealEstate.com, lists refinancing the balance into a new HELOC among the exits when a draw period ends. The others are paying down early, a cash-out refinance of the property, and paying off from rent or other sources. That is the whole menu, and we will cover each branch below.
Who Does This Fit, and Who Does It Not?
It fits an individual or trust-held owner with strong credit, a modest combined balance, and a rental that is not in an LLC. It does not fit LLC-held property, thin equity, or a balance larger than a $500,000 line can cover.
Here is how we sort files across our wholesale network. Lendmire is a mortgage broker. It matches your scenario to a lender rather than lending itself, so the right program depends on your file, not on a product name.
| Your situation | Likely route | Why |
|---|---|---|
| Rental in your name or revocable trust, 700+ credit | New investment HELOC | Replaces only the old line |
| Rental deeded to an LLC | DSCR cash-out refinance | LLCs cannot hold title on these lines |
| Combined balance too high for 70% CLTV | Cash-out refinance or paydown | Line cannot cover the payoff |
| Credit below 700 | DSCR cash-out refinance | 700 is the floor on investment lines |
| Old line sits behind a first mortgage you like | New HELOC, or subordination | First mortgage stays untouched |
How Does Underwriting Treat This, Step by Step?
The lender counts every lien against the property, sizes the new line to the combined limit, values the property, and then checks your credit and debt-to-income ratio. Here is the sequence.
Step 1: Count every lien at its full limit. Gather the first mortgage balance and the old HELOC’s credit limit and drawn balance. Underwriters care about the limit, not only what you drew. The old line is being closed, so its limit disappears from the stack once it is paid off and released.
Step 2: Apply the 70% CLTV ceiling. CLTV adds the first mortgage and the new line’s maximum together, then divides by value. On an investment property, our network tops out at 70% CLTV. Both the 720-plus and 700-plus credit tiers reach that same 70%. So a higher score above 700 buys eligibility, not extra leverage.
Step 3: Confirm the line size. Lines run from $25,000 to $750,000 (Michigan’s floor is $10,000). But a line on an investment property is capped at $500,000. Anything above that is limited to primary residences.
Step 4: Value the property. Because an investment line cannot exceed $500,000, it normally runs through an automated valuation. That usually means no traditional appraisal. A higher CLTV may call for a second valuation, and you can request a full appraisal in any case.
Step 5: Check credit and debt ratio. The minimum credit profile on an investment line is 700. The score comes from a single bureau, keyed to the primary wage earner, on a report no more than 90 days old at closing. The maximum debt-to-income ratio is 50%, calculated on the interest-only payment at the maximum draw. This is a personal-credit-and-DTI product. It is not a rental-coverage product, which is the sharpest contrast with a DSCR loan.
Step 6: Pay off and release. The payoff comes out of closing proceeds. Ask for a written closure and release of the old line. A zero balance alone leaves the lien on record.
Bank-statement income is never the binding constraint here, since investment lines already floor at 700.
What Does the New Line Actually Look Like?
An investment line is a standalone line in first or second lien position, with a 5-year interest-only draw and a 25-year fully amortizing repayment. That is the only structure offered for investment lines. At least 75% of the line is drawn at closing, and pricing floats during both periods. It never converts to fixed.
Three consequences matter for a refinance.
The 75% draw rule shapes the line size. If your payoff is small and you open a big line, you must still draw most of it. You then pay interest on money you did not need. Size the line close to the payoff, with only a modest cushion.
First or second lien both work. If you own the rental free and clear, the new line sits in first position. If a first mortgage stays, the new line goes behind it. Your first mortgage is not repriced either way.
The draw clock restarts. You get five more interest-only years. Principal does not shrink during that time. Then the payment steps up to a fully amortizing one. ConsumerAffairs describes how payments can rise sharply once repayment starts, and how some hybrid lines recast early or cut limits mid-draw.
The same pricing movement the old line had, the new one has too. A refinance changes the date of the cliff, not its existence.
What Is the Difference Between Your Four Routes?
You have four ways out of an old line. Each trades something different.
| Route | What it does | Main tradeoff |
|---|---|---|
| New HELOC | Pays off old line, resets draw | Floats; 70% CLTV cap |
| Cash-out refinance | Rolls HELOC into a new first mortgage | Reprices the whole first lien |
| Refinance first, subordinate old line | New first mortgage; HELOC stays behind | Old lender can say no |
| Pay off with cash | Ends the debt | Uses your own capital |
The subordination route trips people up. When a first mortgage is refinanced, the old first lien is released. A HELOC behind it would normally move up to first position. A new first-mortgage lender will not close in second place. Nolo explains that a subordination agreement reorders the priority so the refinancing lender is paid first, and the HELOC lender must agree to stay second. A clean payment history does not force that agreement. If the HELOC lender refuses, the fallback is payoff or a cash-out roll-in.
On the cash-out branch, our network generally treats a refinance that pays off a HELOC as cash-out, even when no cash comes back to you. A DSCR cash-out refinance tops out around 75% LTV on standard rentals, and about 6 months of seasoning is the common expectation. Our complete DSCR loans guide walks through that product.
Worked Example: A Hypothetical Payoff
This is an illustration with modeled percentages, not a market fact.
Say a rental in your own name is worth 100 points. The first mortgage is 40 points. The old HELOC has a 25-point limit with 20 points drawn.
- Today’s combined limits are 65 points.
- You pay off the old line with a new one sized at 25 points.
- At least 75% must be drawn at closing, so just under 19 points. Your 20-point payoff clears that.
- Combined leverage after closing: 40 plus 25, or 65%. That sits under the 70% ceiling.
Now change one input. Say the old line was drawn at 35 points. The payoff alone pushes combined leverage to 75%. That is over the cap, so the new line cannot cover it. You would need a cash-out refinance, a paydown, or a different plan.
Where Do the Rules Break?
Several edge cases catch people. Know them before you apply.
The rental is in an LLC. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead, subject to program terms.
The property type is wrong. 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 property are not offered.
You are at the exposure limit. A borrower is limited to three lines, with combined-exposure caps that depend on the program. Someone with more than 15 financed properties is not eligible.
Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale a 4-year path.
The old line is on your home, not the rental. Refinancing the rental never touches a lien on your primary residence. And the old lender may have frozen the line. The CFPB HELOC booklet says lenders can reduce or freeze a line if the property’s value drops. A fresh valuation can move that in either direction.
Your state may not be covered. Lendmire’s HELOC availability runs through 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint. In NC, PA, TN, TX, and WA, a property listed for sale, or within the past 60 days, is ineligible. New Mexico and Ohio apply a CLTV cap that depends on the credit profile.
When a DSCR Cash-Out Is the Better Move
A DSCR cash-out refinance fits when the HELOC route is blocked or when you want one fixed-structure loan instead of a floating line.
DSCR, or debt service coverage ratio, compares monthly rent to the full monthly housing payment. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It can sit in an LLC, and leverage runs up to about 75% on a cash-out of a standard rental. Credit floors vary: 620 exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest tiers. Coverage of 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted.
One caution: clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation. Term structures on DSCR loans center on the 30-year fixed, with 40-year terms and interest-only periods available through select lenders.
If you want to tap equity on a rental without selling or refinancing it, Lendmire’s piece Best Investment Property HELOC Program on a Rental Without Selling or Refinancing It covers that separate need.
Key Terms Defined
CLTV (combined loan-to-value): The first mortgage plus the line’s maximum, divided by the property’s value.
Draw period: The stretch when you can borrow and pay interest only. On investment lines in our network it lasts 5 years.
Repayment period: The years after the draw ends, when you pay principal and interest. It lasts 25 years here.
Lien position: Whether a loan gets paid first (first lien) or second if the property is sold at foreclosure.
Subordination: A written agreement where an existing lender agrees to stay behind a new first mortgage.
Release: The recorded document that removes a paid-off line from the property’s title.
DSCR: Debt service coverage ratio, which compares rent to the monthly payment on the property.
How Do You Choose the Best Program for Your Situation?
Start with the constraints, not the product. Ask in this order.
1. Title. Is the rental in your name or a revocable trust? If it is in an LLC, stop and consider a vesting change or DSCR cash-out.
2. Credit. Is your profile at 700 or better? If not, the line is out.
3. Combined leverage. After paying off the old line, do you land at or under 70% CLTV?
4. Lien order. Does the first mortgage stay, and does the new line fit behind it?
5. Payment tolerance. Can you carry interest-only payments for 5 years, then a fully amortizing payment, while pricing floats?
Be honest about the fifth one. This is a genuine toss-up for some investors: the line is cheap to hold while interest-only, but it is a bridge, not a permanent structure. Investors using a line to buy and stabilize the next rental often plan to refinance into long-term financing before the draw ends. Those holding the debt for the long run often prefer fixed structure.
Frequently Asked Questions
Can I refinance an investment property HELOC into a new HELOC?
Yes, on our network, when the property is in your name or a revocable trust, your credit profile is 700 or better, and combined leverage stays at or under 70% CLTV. The new line pays off the old one at closing, the old line closes, and a fresh 5-year draw starts. Approval depends on lender guidelines and a full file review.
Does a new HELOC change my first mortgage?
No. The line is a standalone loan in first or second lien position, so a first mortgage you keep stays as it is. A cash-out refinance does the opposite: it reprices the whole first-lien balance. That difference is one reason investors with a first mortgage they like choose a line.
Will I need an appraisal?
Usually not. Investment lines cap at $500,000, which keeps them in the automated-valuation lane. A higher CLTV may call for a secondary valuation, and you can ask for a full appraisal any time.
What if my rental is in an LLC?
The line is not available while an LLC holds title. You can retitle the property to yourself or a revocable trust, which has its own tradeoffs, or choose a DSCR cash-out refinance, which can lend to an LLC subject to program terms.
Does refinancing remove the risk when my draw period ends?
No. It only moves the date. You face a new 5-year interest-only draw, then a fully amortizing payment, and the pricing floats in both periods. Plan the exit before you sign.
