The Quick Read: Yes, in most cases an owner with a low-rate first mortgage can take a HELOC on the rental and leave that first loan alone, because the line sits behind it as a second lien, though the lender pool is smaller and the leverage is lower than on a primary home. Lendmire brokers this product through select wholesale partners, and the key terms on an investment property are:
- The ceiling is 70% combined loan-to-value (CLTV) on an investment property, and a low first mortgage leaves more room under it.
- Lines run from $25,000 to $500,000, with a 700 minimum credit profile.
- The line is reviewed on the borrower’s credit, equity and debt load, not on rent.
- An LLC cannot hold title, so LLC-owned rentals need a vesting change or a DSCR cash-out instead.
How Does a Line Behind a Low First Mortgage Work?
A rental HELOC is a second lien recorded behind your existing mortgage. The first loan keeps its rate, term and servicer. Nothing about it gets repriced. That is the whole appeal for an owner who would be giving up a cheap loan to pull equity through 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.
The federal consumer-finance regulator describes the typical structure as a draw period followed by a repayment period. The network’s investment line follows that shape: a 5-year interest-only draw, then a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing, so this is not a pure draw-as-needed line. Pricing floats through both periods and never converts to fixed.
The line can also sit in first position when the property is owned free and clear.
Is It Harder Than a HELOC on a Primary Home?
Yes. NerdWallet notes that the product exists on investment property, but you will have fewer lenders to choose from and can’t borrow as much as against a primary home. That matches what a broker sees.
Here is how the network treats occupancy:
| Factor | Investment property | Primary residence |
|---|---|---|
| Max CLTV | 70% | Up to 90% at 720+ credit |
| Credit minimum | 700 | 600 program floor |
| Max line | $500,000 | Up to $750,000 |
| Draw structure | 5-year draw, 25-year repayment | Two structures available |
The investment table has only two tiers. A 720 score and a 700 score both reach 70% CLTV, so credit above 700 buys eligibility, not leverage. And 700 is a hard floor with no tier beneath it. Market surveys report investment-property CLTV caps in a range up to 80%, per Experian, but on this network an investment line stops at 70%.
The Headroom Math (Why a Low First Helps Twice)
A low first mortgage helps because the cap applies to all liens combined. Take the property value, multiply by the 70% cap, then subtract the first mortgage balance and any existing second. What remains is the most the line can be.
Run it in percentages. Say the first mortgage equals 40% of the property’s value. With a 70% cap, roughly 30% of value is available, up to the $500,000 line maximum. Now say the first equals 65% of value. Only about 5% of value is left, and that may not clear the $25,000 minimum line.
A first sitting at about 70% of value leaves nothing, so there is no line to offer.
Two other points on the math:
- Values move and the first mortgage balance doesn’t follow. If the property value falls, the usable line shrinks with it.
- Investment lines top out at $500,000, and full appraisals start only above that size. So an investment HELOC is structurally in the automated-valuation lane and commonly closes with no traditional appraisal. A borrower may still request a full appraisal. That can matter after heavy rehab, because an automated value may not reflect recent improvements.
This is the headroom logic behind Lendmire’s piece How to Qualify for a HELOC for Homeowners Locked Into a Low First Mortgage.
What Underwriters Actually Look At
The line is reviewed on the borrower, not the rent. That is the sharpest difference from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The file for a rental HELOC looks like a personal-credit file:
- Credit: 700 minimum on an investment line. A single-bureau score keyed to the primary wage earner, with a report no more than 90 days old at closing.
- Debt-to-income: 50% maximum. Above 45% requires at least 680 credit, and the ratio is calculated on the interest-only payment at the maximum draw.
- Exposure: a borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.
- Property types: single-family, 2-4 units, PUD, townhome and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural zoning are not offered.
- Listing status: in some states, a property listed for sale or listed within the past 60 days is ineligible. Keep proof it isn’t on the market.
- Availability: this product is arranged only in Lendmire’s 16 full-service states, which is narrower than its DSCR footprint.
Title: The LLC Problem
An LLC cannot hold title on this product. The same goes for corporations, partnerships, and irrevocable, blind or land trusts. Title must sit with the individual borrower or an inter vivos revocable living trust.
If the rental is already deeded to an LLC, you have two options. Change the vesting to your own name or a revocable trust, which has its own considerations around insurance and liability that are worth a call with an attorney. Or skip the HELOC and use a DSCR cash-out refinance, which allows entity title, subject to program terms.
Keep the First, or Refinance?
The choice comes down to what you want to protect. A cash-out refinance replaces the first mortgage and resets its rate on the entire balance. A HELOC reprices only the amount you draw.
| Option | What happens to the first | How you qualify | How funds arrive |
|---|---|---|---|
| Investment HELOC | Stays in place | Borrower credit and DTI | Line, 75%+ drawn at closing |
| DSCR cash-out | Replaced | Rent covering the payment | Lump sum |
| Home equity loan | Stays in place | Borrower credit and DTI | Lump sum |
The CFPB classes both HELOCs and home equity loans as second mortgages paid on top of the first. The difference is lump sum versus revolving access.
Whether the line beats a refinance depends on how far your first mortgage sits below what a new loan would cost, and on how much cash you need. A small draw against a very cheap first usually favors the line. A large need favors the refinance, because a DSCR cash-out reaches about 70% LTV on a standard rental, versus 70% CLTV on the HELOC, and has no $500,000 line cap. For a mid-sized need, neither option clearly wins, so price both side by side.
Rent does not factor into the review on the HELOC side, but it matters if you later want DSCR financing, since those loans measure whether a property’s rent covers its debt payments. A new HELOC adds debt to your personal profile, and its effect on a later loan should be checked against that program’s guidelines. For the full picture of how rent-qualified loans work, see the complete DSCR loans guide.
Key Terms Defined
Second lien: a loan recorded behind the first mortgage, paid from sale proceeds only after the first is satisfied.
Combined loan-to-value (CLTV): all loans on the property added together, divided by its value.
Draw period: the stretch when you can borrow from the line and pay interest only.
Repayment period: the stretch after the draw ends, when principal and interest amortize the balance.
Vesting: the legal name in which the property’s title is held.
Risks Investors Should Price In
The rental is the collateral. The CFPB’s page on what a HELOC is warns that default can cost you the property. Cross-collateral exposure is real if the line is large relative to the rent roll.
Pricing floats. A draw that fits your cash flow today can strain it if payments reset higher, so stress-test the draw before closing. Interest-only payments during the draw period also hide principal that will come due in the repayment stage.
If you sell, you are generally required to pay the HELOC off in full. Plan for that at exit.
What to Gather Before You Apply
A clean file has fewer preventable gaps. Pull these first:
1. Current deed or title evidence showing the individual or revocable trust as owner.
2. A payoff statement for the first mortgage and any other lien.
3. A current value estimate, so you can run the CLTV math before anyone else does.
4. Proof the property is not listed for sale.
5. A recent credit report review, since the 700 floor is firm.
6. Standard income and debt documents for the DTI calculation.
If the property is in an entity, the need is above $500,000, or the first mortgage is near the cap, the DSCR cash-out route is usually the cleaner path. Lendmire’s piece on the best HELOC program for homeowners locked into a low first mortgage covers how to sort the fit.

Frequently Asked Questions
Can I keep my low first mortgage and still pull equity from a rental?
Yes. A HELOC or home equity loan is a second lien, so the first mortgage stays with its original rate and term. The limit is combined leverage: on an investment property, all liens together must stay within 70% CLTV on this network, subject to lender guidelines.
Can I use a HELOC if the rental is in my LLC?
Not on this product. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. You would need to change vesting to yourself or a revocable living trust, or use a DSCR cash-out refinance, which allows entity title per program terms.
How much can I borrow on an investment property?
Lines run from $25,000 to $500,000, capped at 70% CLTV with a 700 minimum credit profile. The actual amount is the 70% cap applied to value, minus your first mortgage and any other liens. A first mortgage near 70% of value leaves nothing available.
Is the line qualified on rent like a DSCR loan?
No. It is reviewed on your credit, equity and debt-to-income ratio, which can run up to 50%. Rent isn’t the qualifier. A DSCR loan works the opposite way and looks to the property’s rental income covering its payment.
Will I need a full appraisal?
Usually not. Investment lines cap at $500,000, and lines at or below that size ordinarily use automated valuation. A borrower may request a full appraisal, which can help after major rehab that an automated value would miss.
