The Quick Read: Lenders do write interest-only HELOCs on rentals, but the pool is small. On Lendmire’s wholesale network, an investment line caps at 70% combined loan-to-value, runs a 5-year interest-only draw before 25 years of fully amortizing repayment, and generally expects a 700 credit score, with title held in your own name or a revocable trust. The interest-only stretch is temporary, so the real decision is how you will handle the payment when it ends.
- Investment lines top out at 70% CLTV and $500,000, with a $25,000 minimum line (a lower floor applies in Michigan).
- Interest-only applies only during the 5-year draw. Repayment then covers principal and interest over 25 years.
- At least 75% of the line is drawn at closing, and pricing floats for the whole life of the line. It never converts to fixed.
- An LLC cannot hold title on these lines. A property deeded to an LLC usually points toward a DSCR cash-out refinance instead.
- Every figure here is subject to lender guidelines and full file review, and none is a commitment to lend.
Key Terms Defined
You will see these terms throughout. Each is defined once here.
- HELOC: a home equity line of credit, a revolving credit line secured by property you already own.
- Draw period: the stretch when you can borrow against the line and make interest-only payments.
- Repayment period: the stretch after the draw ends, when borrowing stops and you pay principal plus interest.
- CLTV (combined loan-to-value): your first mortgage plus the new line, divided by the property’s value.
- DTI (debt-to-income): your monthly debts divided by your monthly income.
- Lien position: where a loan stands in line to be repaid if the property is sold. First lien is paid first.
- Payment shock: the jump in your payment when interest-only ends and principal is added.
- PITIA: principal, interest, taxes, insurance, and association dues. It is the full monthly housing obligation.
- DSCR (debt service coverage ratio): monthly rent divided by PITIA. It is how DSCR loans qualify a rental.
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.
Why Are Investment Property HELOC Lenders So Hard to Find?
Few lenders write lines against rentals because they see more default risk than on an owner-occupied home. NerdWallet notes that a HELOC on an investment property is possible, but fewer lenders offer one, qualification is strict, and you can borrow less than you could against a primary home.
That matches what shows up on files. Many large retail banks decline rentals outright. Some credit unions and regional lenders write them with tight limits. A handful of wholesale lenders treat the product as a standard offering, and a broker is the usual way to reach them.
Here is the practical difference. A single bank gives you one set of overlays and one answer. A broker shops several wholesale lenders and matches the property, credit, and leverage need to the program that fits. The lenders that write this product, and the terms they use, depend on your property type, credit profile, how much equity you hold, and how the title is vested. Lendmire is a broker, not a lender. It arranges these lines through select wholesale partners, and the lender reviews eligibility.
One more limit to know up front: these HELOC programs run in 16 states, which is narrower than Lendmire’s DSCR footprint of 40 states plus D.C. (41 markets total). Availability is checked file by file.
How Does an Interest-Only Investment HELOC Work, Step by Step?
You qualify on equity and credit, the line sits behind or in front of your mortgage, and you pay interest only during the draw. Then borrowing stops and the payment resets to principal plus interest. The balance does not shrink until that reset.
1. The equity test. The lender adds your existing first mortgage to the new line and divides by the property’s value. On an investment property, the network ceiling is 70% CLTV. Credit above 700 does not buy more leverage. Both the 720 and 700 tiers reach the same 70%.
2. The lien position. The line can sit in first or second position. On a mortgaged rental it usually sits second, behind the existing loan. On a free-and-clear rental it can take first position.
3. The draw. During the draw period you can borrow, repay, and borrow again up to your limit. The CFPB explains that you can generally borrow up to your credit limit at any point in the draw period, and it uses 10 years as an example. Investment lines on this network use a 5-year draw instead. At least 75% of the line is drawn at closing, and later draws generally carry a $1,000 minimum, though a few states set it higher.
4. Interest-only payments. Interest accrues only on what you have drawn. Paying interest alone never reduces the balance.
5. The repayment period. Borrowing stops. The CFPB notes that lenders often schedule full repayment over 10 or 20 years. On this network’s investment structure, the balance amortizes over 25 years.
6. Floating pricing. Pricing moves with an index through both the draw and the repayment. Even if your balance never changes, the interest-only payment can.
Skip the idea that the draw lasts as long as the loan. It does not.
How Do Lenders Underwrite the Interest-Only Payment?
Lenders test you on the interest-only payment calculated on the maximum draw, not on what you have actually borrowed. If your line is $400,000 and you draw $300,000, the qualifying payment still assumes the full line. That is conservative by design, and it surprises many borrowers.
Here is what the file looks like across the network’s investment lines:
- Credit: a 700 minimum, taken from a single-bureau score keyed to the primary wage earner. The report must be no more than 90 days old at closing, and there are no rescores.
- DTI: 50% maximum.
- Valuation: a line capped at $500,000 ordinarily runs on an automated valuation, with no traditional appraisal. A higher CLTV may call for a secondary valuation, and you can request a full appraisal in any case.
- Past credit events: a bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years. A deed-in-lieu, pre-foreclosure, or short sale needs 4.
- Exposure: you are limited to three lines, and an investor with more than 15 financed properties is not eligible.
DSCR matters less here than you might expect. These lines are underwritten on you as a borrower: credit, DTI, and equity. A DSCR loan, by contrast, qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That is the single most important difference between the two products. If you are new to the rent-based side, Lendmire’s complete DSCR loans guide walks through it.
Structures and Variations
On investment properties, one structure is available through this network: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. That is it.
Primary residences and second homes get a second option, a 3-year draw followed by a 17-year repayment. Primary-home lines also reach higher leverage. A primary residence can go up to 90% CLTV, but only at a 720-or-better credit profile. That ceiling never applies to a rental.
Some lenders in the wider market write whole-term interest-only lines that end in a balloon payment. That structure is lender-specific. The investment lines Lendmire places do not work that way, so ask any lender which version you are being quoted.
Lines above $500,000 exist only on primary residences and need a full appraisal. An investment line stays at $500,000 or below. For a closer look at how interest-only periods and deferment features compare across lenders, see Lendmire’s piece HELOC Lenders With Payment Deferment or Interest-Only Options.
Where the General Rule Breaks
The standard path works for a one-to-four unit rental held in your name with solid credit and real equity. These edge cases change the answer.
LLC-held property. This is the sharpest break. Title must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change before a HELOC works, or a DSCR cash-out refinance instead.
Property type. Single-family, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned properties are not offered. Barndominiums also fall outside the network’s investor programs.
Credit under 700. There is no tier beneath 700 on an investment line. A 680 score can work on other products, but not here.
A listed property. A rental that is listed for sale, or was listed recently, is ineligible in several states.
Many properties. The three-line limit and 15-property cap catch portfolio investors first. If you are scaling fast, check them before you apply.
Using your own home. A HELOC on your primary residence is a different product with higher leverage, and it is often easier to get than a line on the rental. NerdWallet lists this and the cash-out refinance as the main alternatives. The cost is that your home, not the rental, becomes the collateral for your investing.
Payment Shock, Without the Spin
Picture a rental in your name with a first mortgage near half of its value. You open a line that brings CLTV to the 70% ceiling and draw at least 75% of it at closing. For five years, your payment on that draw is interest only. The balance does not move.
Then the draw ends. The same balance must now amortize over 25 years, with principal added on top of interest. Because pricing floats, the new payment depends on where the index sits that day. Expect a meaningful step up, and run it before you borrow.
Use two checks, not one:
| Phase | What to test | Pass condition |
|---|---|---|
| Draw (years 1-5) | Rent vs first mortgage + line interest | Rent covers both with margin |
| Repayment (after) | Rent vs first mortgage + amortizing line | Same, at a stressed index level |
Clearing a coverage ratio is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside that math. (Many first-time investors learn that the expensive way.)
Is a HELOC or a DSCR Cash-Out Refinance the Better Fit?
The best program for your situation depends on how the title is held, what you need the money for, and whether your personal income or the rent tells the stronger story. A HELOC and a DSCR cash-out refinance are different products. Here is the side-by-side:
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Your credit, DTI, equity | Rent vs PITIA |
| Existing first mortgage | Stays in place | Replaced |
| Typical ceiling | 70% CLTV | About 75% LTV, standard rental |
| Payment structure | 5-yr interest-only, then 25-yr amortizing | 30-year fixed spine; IO via select lenders |
| Title | You or revocable trust | LLC possible |
The leverage figures measure different things. The HELOC’s 70% counts the first mortgage plus the line. The cash-out’s 75% covers the single new loan that replaces the old one. On short-term-rental collateral, the cash-out ceiling drops to 70%.
A DSCR cash-out typically wants about six months of seasoning. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Most programs want around 660 credit, though a 620 floor exists in parts of the network. Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. LLC-titled borrowers can use this route, subject to lender program eligibility.
The HELOC keeps your existing first loan untouched. That matters if your current mortgage carries terms you would not replace. The cash-out resets everything but gives you property-based qualification and a fully amortizing fixed structure.
What to Do Before the Draw Ends
Pick your exit before you open the line, not in year five. You have four realistic options.
- Pay down the balance from rents, savings, or a sale, so the reset hits a smaller number.
- Refinance into a DSCR cash-out to replace both loans, if the rent covers the new payment.
- Sell the property and retire the line from proceeds.
- Accept the reset and run the stressed numbers to confirm the rent can carry it.
Stacking a second lien raises total leverage, so build in margin.

Questions to Ask Any Lender Before You Apply
This is the screening list that separates a real offer from a vague “may be available.”
1. Does the interest-only draw apply to a non-owner-occupied property?
2. How long is the draw, and how long is the repayment?
3. Is interest-only for the draw only, or for the whole term with a balloon?
4. How much must be drawn at closing?
5. Does pricing float, and does it ever convert to fixed?
6. Will you qualify me on the maximum draw?
7. Can the property sit in an LLC or trust?
8. Is a traditional appraisal required?
9. What is the limit on lines and financed properties?
Get the answers in writing. Programs change, and every file is underwritten individually.
Frequently Asked Questions
Can I get an interest-only HELOC on a rental property?
Yes, through a limited number of lenders. On Lendmire’s network, an investment line runs a 5-year interest-only draw and then a 25-year fully amortizing repayment. You need roughly a 700 credit score, the title in your name or a revocable trust, and CLTV at or below 70%. Eligibility is subject to lender guidelines.
Does interest-only mean I am paying the loan down?
No. Interest-only payments cover interest on the drawn balance and nothing else. The balance stays the same until the repayment period begins, when principal is added to the payment.
Can my LLC take out an investment property HELOC?
Not on these programs. Title must be held individually or in a revocable living trust. If the property is already in an LLC, a DSCR cash-out refinance is the usual alternative.
What happens to my payment when the draw ends?
It steps up, often by a lot. Borrowing stops and the balance amortizes over 25 years on an investment line. Because pricing floats, the new payment also depends on the index at that point.
How does a DSCR loan differ from a HELOC on a rental?
A DSCR loan is reviewed primarily on property-level rental income covering the payment. An investment HELOC is reviewed on your credit, DTI, and equity. A DSCR cash-out also replaces your first mortgage, while a HELOC adds a line beside it.
