The Quick Read: A home equity line on a rental sits behind your existing first mortgage, so the first loan keeps its terms, and what limits the line is the first mortgage’s balance, your credit profile, how the property is titled, and the combined leverage cap, not its interest rate.
- On this network, an investment-property line caps at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
- Title must be in your own name or a revocable living trust. An LLC cannot hold title on this product.
- Qualification runs on your personal debt-to-income ratio, with a 50% maximum, not on rent coverage.
- Lines are floating-price, and at least 75% of the line is drawn at closing.
- Availability is limited to Lendmire’s 16 full-service states, which is narrower than its DSCR footprint.
How Does a HELOC Work Behind a First Mortgage You Are Keeping?
A HELOC on a rental is a second lien. It leaves your first mortgage untouched, and it adds a separate payment. NerdWallet notes that tapping equity this way does not require changing your mortgage rate, unlike a refinance.
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 is the reason investors with an older, cheaper first loan look at this product. The new cost applies only to the new money. The old loan keeps running as written.
The catch is availability. Experian points out that not every lender offers lines on investment properties, and big banks and large retail lenders often decline them. Lendmire is a broker. It places these lines through select wholesale partners and never lends directly.
Across that wholesale network, the line can sit in first or second lien position. If your rental is free and clear, the line can simply be the first lien.
Key Terms Defined
Combined loan-to-value (CLTV): the total of all liens on the property divided by its value.
Second lien: a loan recorded behind the first mortgage, paid second if the property is sold or foreclosed.
Draw period: the stretch when you can borrow against the line and payments are interest-only.
Repayment period: the stretch after the draw period when the balance amortizes and you can no longer borrow.
DSCR (debt service coverage ratio): monthly rent divided by the full monthly property obligation, which is principal, interest, taxes, insurance and any HOA dues.
Vesting: the legal form of ownership on the deed, such as an individual, a trust or an LLC.
What Are the Investment Property HELOC Requirements?
On this network, an investment-property line runs up to 70% CLTV, with a $500,000 maximum line and a 700 minimum credit score. Credit above 700 does not raise the investment ceiling. It only confirms eligibility. Everything below is subject to lender guidelines and full file review.
| Requirement | Investment-property line |
|---|---|
| Maximum CLTV | 70% |
| Minimum credit score | 700 |
| Line size | $25,000 to $500,000 |
| Draw structure | 5-year interest-only draw, 25-year repayment |
| Drawn at closing | At least 75% of the line |
| DTI | 50% maximum |
| Title | Individual or revocable living trust |
| Valuation | Usually automated, no traditional appraisal |
A few details matter more than the table suggests.
Pricing floats. It floats through both the draw and repayment periods, and it never converts to a fixed structure. Plan the second payment as a moving number.
Qualification is personal. Lenders run your debt-to-income ratio, and they calculate it on the interest-only payment at the maximum draw. Yahoo Finance notes that lenders weigh both the borrower and the property’s financials. On this product the weight falls mostly on you, your credit and your existing debts.
Valuation is mostly automated. Because an investment line tops out at $500,000, and full appraisals begin only above that, the file normally uses an automated valuation. You can still request a full appraisal.
Credit reports age out. The report cannot be more than 90 days old at closing, and the lender does not rescore.
Market surveys report that lenders offering these lines on rentals often look for scores around 720, leverage caps of up to 80% and many lenders below 70%, reserves of six months or more, and DTI between 40% and 50%, per NerdWallet. Those are market-wide figures. The network figures for an investment property are the ones in the table: 70% CLTV, a 700 floor and 50% DTI. Reserve requirements vary by lender and file.
Why the First Mortgage Balance Matters and Its Rate Does Not
Your line is sized by what you owe, not by what you pay. A first mortgage at a very low rate and one at a high rate leave the same room if the balances match. Combined leverage counts every lien against value, so the balance eats into the 70% ceiling.
| First mortgage as share of value | Room under 70% CLTV | What usually binds |
|---|---|---|
| 30% | 40 points | The $500,000 line cap on higher-value properties |
| 50% | 20 points | CLTV on most properties |
| 65% | 5 points | CLTV, and the $25,000 minimum line may not fit |
| 70% or more | None | No line is available |
Take a rental where the first mortgage is half the property’s value. Under the 70% ceiling, the line can add up to about 20 points of value. If the property is worth enough that those 20 points exceed $500,000, the line cap stops you first.
Cheap debt that has been paid down gives you the most room. Cheap debt on a recent high-leverage purchase gives you very little, no matter how good the rate is.
Is Your Locked-in Mortgage Worth Keeping?
Keep the first loan when the cash you need is small compared with the balance you would reprice. A line prices only the new money. A cash-out refinance reprices the entire loan.
Use this screen:
- Small draw, big gap between your rate and today’s market: the HELOC usually fits.
- Large cash need, first balance already near 60% of value: the 70% ceiling leaves little room, so a refinance may be the only way to reach the amount.
- Property titled in an LLC: the line is blocked until you change vesting, which may defeat the point.
- Income built on rent rather than personal DTI: a rent-based cash-out structure often fits better than a personal-income line.
HELOC Versus Cash-Out Refinance on a Rental
A HELOC preserves your first lien and a cash-out refinance replaces it. The structural differences go beyond the payment.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Paid off and replaced |
| Max leverage | 70% CLTV | Around 75% LTV on standard rentals |
| Underwriting basis | Personal DTI and credit | Property rent versus payment |
| Title | Individual or revocable trust | LLC allowed, subject to program eligibility |
| Payment type | Floating, interest-only draw | Fixed-rate structures available |
| Seasoning | Not the focus | About 6 months common |
The DSCR route qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Programs often start at 1.00 coverage, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. The complete DSCR loans guide covers how that works.
Clearing 1.00 is not the same as positive cash flow. DSCR compares rent to the payment only, so repairs, vacancy, management and capital costs sit outside the calculation.
Think of an investor with a small cash need and a first mortgage at about 40% of value. The line adds a second payment, and the first loan stays the same. A refinance on the same property would reprice the whole balance to fund a modest draw.
Now flip it. With a large cash need and a first mortgage already above 60% of value, the HELOC runs out of room. The refinance reaches further, and it also lets an LLC stay on title.
Where the Rule Breaks: Edge Cases That Fail Files
Most failures come from title, leverage or property type.
LLC title. An LLC, corporation, partnership or irrevocable, blind or land trust cannot hold title on this line. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. Retitling can raise lender-consent and title-insurance questions with your existing first mortgage, so get advice first.
Stacked leverage. A first mortgage above 65% of value leaves almost nothing under the cap.
Property type. Eligible: single-family, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos. Not eligible: manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use or agricultural zoning.
Listed property. In several states, a property listed for sale, or listed within the past 60 days, is ineligible.
Portfolio size. A borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.
Credit history. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure needs seven years, and a deed-in-lieu, pre-foreclosure or short sale needs four.
State coverage. This line is available only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. Texas investment properties are eligible as non-homestead transactions, and Texas properties are limited to 10 acres. New Mexico and Ohio apply a CLTV cap that depends on the credit profile.
What Risks Come With a Second Lien Behind a Locked-in Loan?
The risks are real, and you carry all of them.
- Floating payment behind a fixed first. Your fixed loan stays steady while the second payment moves.
- Two payments from one rent. The rent has to carry both, and the HELOC payment lowers your coverage on any later DSCR refinance.
- Foreclosure exposure. Experian cautions that default can put the rental at risk of foreclosure.
- Lien order on a later refinance. If you refinance the first mortgage later, the second lienholder has to agree to stay behind it.
- Falling values. Because CLTV counts every lien, a value decline can shrink room you thought you had.
Step-by-Step: How the deal works
1. Pull the first mortgage payoff balance and the property value estimate. Divide the balance by value to see your room under 70%.
2. Confirm vesting. The deed must show you personally or your revocable living trust.
3. Confirm property type and listing status. Check against the eligibility list above.
4. Gather credit and debt documents. Expect a 700 minimum score and a DTI at or below 50%.
5. Decide the draw plan. At least 75% of the line is drawn at closing, so size the line to cash you will actually use.
6. Compare against a DSCR cash-out. If title, room or DTI fails, the rent-based route may fit better.

Frequently Asked Questions
Does my low first-mortgage rate help me qualify for the line?
No. The line is sized by your balance, your credit score, your DTI and the 70% CLTV ceiling. A cheap first loan keeps its terms, but it does not buy extra room.
Can I get a HELOC on a rental owned by my LLC?
Not on this product. Title must be held by you or your revocable living trust. An LLC-owned rental needs a vesting change or a DSCR cash-out, subject to lender program eligibility.
What happens if my first mortgage is too large?
If the first balance is near 70% of value, no line fits under the cap. A refinance may reach further, with leverage around 75% on standard rentals and about 6 months of seasoning commonly expected.
Do I need to document rental income?
The line is reviewed on your personal credit and debt-to-income ratio, not on rent coverage. A DSCR loan works the other way, qualifying primarily on rental income covering the payment.
Is a HELOC the same as a DSCR loan?
No. A HELOC is a floating-price second lien tied to your personal profile. A DSCR loan is a business-purpose investor loan reviewed on the property’s rent against its payment.
