The Quick Read: Approval depends on equity, credit, your personal debt load, and how the rental is titled. On Lendmire’s wholesale network, an investment-property line caps at 70% combined loan-to-value, needs at least a 700 credit score, and tops out at $500,000, subject to lender guidelines and full file review. Rolling an old balance into a new line is a brand-new application, not a rate swap.
- Equity: the ceiling is 70% CLTV on an investment property, counting your first mortgage plus the new line.
- Credit: 700 is the floor, and nothing above it buys more leverage.
- Debt load: the line is judged on you, with a 50% maximum debt-to-income ratio, not on rent coverage.
- Title: an LLC cannot hold title, so a property deeded to one needs a different route.
What Does It Mean to Refinance a Balance Into a New HELOC?
A HELOC (home equity line of credit) is a revolving credit line secured by property you own. On a rental, the rental itself is the collateral. Refinancing a balance into a new HELOC means the new line’s first draw pays off the old line, and the old line closes.
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.
This is not a rate-and-term tweak. The new lender underwrites you and the property from scratch. You get a new credit pull, a new valuation, and a new draw period.
It is also not a DSCR loan. DSCR stands for debt service coverage ratio, which compares a property’s rent to its monthly payment. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. An equity line is a different product with a different test.
Investors usually do this for one of three reasons: the draw period on the old line is ending, the old line has a lower limit than they need, or they want terms they can plan around. Keeping the first mortgage in place is the other common reason. A line sits beside it, while a cash-out refinance replaces it.
How Hard Is It to Get a HELOC on a Rental?
It is harder than on your own home. NerdWallet reports that fewer lenders offer these lines and that you usually can’t borrow as much as you could against a primary residence. It also notes that lenders see a rental as higher default risk, since a borrower in trouble tends to pay the home they live in first.
That matches what we see across the network. Investment lines get the tightest leverage, the highest credit floor, and the narrowest property and ownership rules.
What Do Lenders Check Before Approving the Line?
Underwriting tests six things, in roughly this order. Each one can stop the file.
1. Combined loan-to-value (CLTV)
CLTV is every lien on the property added together, divided by its value. Lenders generally test the full credit limit, not just the drawn amount. On an investment property, the network ceiling is 70% CLTV.
Some markets advertise higher CLTV figures on equity lines. Those describe the broader market. On this network, an investment line does not go above 70%.
2. Credit
The minimum credit score on an investment line is 700. Both the 700 tier and the 720 tier reach the same 70% CLTV, so a higher score buys eligibility, not extra leverage. Scores come from a single-bureau model keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed.
Past credit events matter too. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure follows a seven-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows a four-year path.
3. Personal debt-to-income (DTI)
This is where a HELOC differs most from DSCR financing. The maximum DTI is 50%, and a ratio above 45% requires a 680 minimum score, which an investment file already clears. The payment is calculated on the interest-only payment at the maximum draw, not on what you actually borrow.
Investors with many financed properties often run into this limit first. Self-employed borrowers can qualify on documented income under the applicable program, subject to lender guidelines.
4. Rental documentation and reserves
Expect to document the lease, and possibly rental income on your tax return. Reserve requirements and how much rent counts toward income vary by lender. Ask both questions before you apply.
5. Valuation
An investment line can’t exceed $500,000, and full appraisals begin above that size. So an investment line is nearly always valued by an automated model with no traditional appraisal. A higher CLTV may trigger a secondary valuation, and you can request a full appraisal at any time.
6. Title and property type
The property must be held by you individually or by your revocable living trust. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable ones) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Investment Line vs. Primary-Residence Line
The same product looks different depending on occupancy. This table shows the network’s figures for each.
| Factor | Investment line | Primary residence |
|---|---|---|
| Max CLTV | 70% | Up to 90% (720+ only) |
| Minimum credit | 700 | 600 program floor |
| Max line size | $500,000 | $750,000 |
| Draw structure | 5-year draw, 25-year repay | 3/17 or 5/25 structures |
| Valuation | Automated, under $500,000 | Full appraisal above $500,000 |
A line above $500,000 is primary-residence only. It needs at least a 700 credit profile (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal. Minimum line size is $25,000 (Michigan allows $10,000). Subject to lender guidelines, a borrower is limited to three lines, and a borrower with more than 15 financed properties is not eligible.
How the Payoff Works, Step by Step
1. Pull your numbers. Gather the first-mortgage balance, the old line’s limit and balance, and a realistic value.
2. Check the lien position. The new line can sit in first or second position. On a free-and-clear rental it may be a first lien. If you keep a first mortgage, that mortgage must permit a second lien.
3. Apply and underwrite. The lender reviews credit, DTI, title, property type, and valuation.
4. Payoff and release. At closing, the new line’s initial draw is wired to the old lender. The old line closes and its lien is released. If it stays open, the new lender will generally not take its position.
5. Draw period starts. On an investment line, you get a five-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats during both periods and never converts to fixed.
One mechanic catches borrowers off guard. At least 75% of the line is drawn at closing. So a new line sized far above your old balance forces you to take cash you may not want. Size the line near the payoff, and leave the rest available for later.
A Worked Example in Percentages
These inputs are modeled assumptions, not market data. Work in percentages of the property’s value.
- First mortgage: 45% of value.
- Old HELOC balance: 15% of value.
- Current CLTV: 60%.
- Network ceiling on an investment property: 70%.
Say you open a new line sized at 20% of value. At least 75% of it, or 15% of value, is drawn at closing. That exactly covers the old balance. Your new CLTV is 65%, which leaves 5% of value of headroom under the ceiling. After the payoff, that undrawn 5% is your real net availability.
A larger line is possible. A line at 25% of value would reach the 70% ceiling. But 75% of that line is 18.75% of value, so you would take about 3.75% of value in cash at closing beyond the payoff.
Now flip it. Say the first mortgage is 60% of value and the old HELOC balance is 15%. You are already at 75%, over the 70% ceiling. You would have to pay down about 5% of value before any new line could pass. That is why a falling valuation can block a refinance that looked routine on paper.
Where the General Rule Breaks
Properties held in an LLC. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest difference from a DSCR loan. A property already deeded to an LLC needs a vesting change, or it is a candidate for a DSCR cash-out instead.
Recently listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Texas investment properties. Texas investment properties qualify as non-homestead transactions. Texas properties are limited to 10 acres. The Texas homestead rules apply to primary residences only.
New Mexico and Ohio. Both states apply a CLTV cap that depends on the credit profile.
Seasoning after purchase. Some lenders want a waiting period between buying a property and opening a line against it. The length varies by lender, so ask before you apply.
Availability. Lendmire’s equity-line work covers 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 its DSCR footprint of 41 markets, including Washington, D.C.
Variable pricing. Pricing floats for the life of the line. When the draw period ends, the payment steps up as the balance begins to amortize. Run your numbers on the repayment period, not just the draw period.
Your own home’s equity. A line on your primary residence is a separate transaction, underwritten as owner-occupied. The collateral is your home, not the rental.
Is a New HELOC the Right Move?
Sometimes it is, and sometimes another path fits better. This table compares the options for an investor with an existing balance.
| Factor | New HELOC | DSCR cash-out | Keep old line |
|---|---|---|---|
| Underwritten on | You: credit, DTI | Property rent vs. payment | Already done |
| First mortgage | Stays in place | Replaced | Stays in place |
| LLC title | Not eligible | Per program terms | N/A |
| Pricing behavior | Floats, never fixed | Program-dependent | Existing terms |
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. If your debt load is heavy or the property sits in an LLC, a DSCR cash-out can repay both liens in one step. Our complete DSCR loans guide explains how that structure works. Cash-out refinances on standard rentals top out around 75% LTV across most of the network, with about six months of seasoning as the common expectation, subject to lender guidelines.
The case for a new line is simple. You keep a first mortgage you are happy with, and you only pay on what you draw. The case against is just as clear. The lien is on the rental itself, so missed payments put that property at risk. Vacancy hits your cash flow while the payment keeps running.
For a deeper look at how lenders compare these lines, see Lendmire’s explainer HELOC Requirements for Refinancing a Balance Into a New HELOC.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction, as IRS Publication 936 explains for home mortgage interest.
Readiness Checklist Before You Apply
- Current statements for the first mortgage and the old line, showing balance and limit.
- A realistic value estimate, so you know your CLTV before the lender does.
- Proof of how the property is titled, and confirmation it is not in an LLC.
- A current lease and rent history for each rental unit.
- Income documentation that fits your profile.
- A credit report you have reviewed, with any past derogatory events checked against the seasoning rules above.
- A count of your financed properties and open equity lines against the exposure limits.
- Confirmation that the property has not been listed for sale in the past 60 days, if it sits in one of the six listed states.
Key Terms Defined
CLTV (combined loan-to-value): All loans secured by the property, added together and divided by its value.
Draw period: The stretch of time when you can borrow from the line and pay interest only.
Repayment period: The stretch after the draw period when the balance amortizes and the payment includes principal.
Lien position: Whether a lender’s claim on the property is first or second in line to be repaid.
Seasoning: The waiting period a lender wants between two events, such as buying a property and borrowing against it.
Vesting: The legal form in which title to the property is held.
Frequently Asked Questions
Can I refinance an investment property HELOC balance into a new HELOC?
Yes, if you pass a fresh underwriting review. The new line’s initial draw pays off the old line, and the old line closes. On Lendmire’s network, an investment line is limited to 70% CLTV and $500,000, with a 700 minimum credit score, subject to lender guidelines.
Does the rent from my tenants qualify me for the line?
The line is judged mainly on your personal profile: credit, DTI, and equity. Documented rental income can help your debt-to-income picture, but how much counts varies by lender. A DSCR loan works the opposite way, since it qualifies primarily on the property’s rental income covering the payment.
Can I do this if the rental is owned by an LLC?
Not directly. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. You would need to move title to yourself or to a revocable living trust, or consider a DSCR cash-out instead.
Will I need a full appraisal?
Usually not. An investment line is capped at $500,000, and full appraisals begin above that size. So these lines are ordinarily valued by an automated model. A higher CLTV may require a secondary valuation, and you can request a full appraisal at any time.
What if my property value has dropped?
A lower value raises your CLTV, and it can push you over the 70% ceiling. In that case you may need to pay down the old line or the first mortgage before the new line passes. Another option is to refinance into a DSCR loan, which is underwritten on rent coverage and has different leverage rules.
