Investment Property HELOC Lenders With Interest-Only Payments

The Quick Read: A home equity line on a rental is a narrow product, and the interest-only draw is the feature that makes it useful and the feature that makes it risky. Lendmire is a mortgage broker, so it does not lend. It places these lines with select wholesale lenders, and which lender fits depends on your property, credit, equity and goals.

• On an investment property, the network’s ceiling is 70% combined loan-to-value (CLTV), with a maximum line of $500,000 and a 700 minimum credit score.
• The investment structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment.
• At least 75% of the line is drawn at closing, so this is not a standby reserve you leave untouched.
• The line is qualified on you (credit and debt-to-income), not on the rent. A DSCR cash-out refinance qualifies the property instead.
• Title must sit with you personally or in a revocable living trust. An LLC cannot hold title on the line.

Can You Get a HELOC on a Rental Property at All?

You can, but the pool is smaller than for a primary-residence line. Many large retail lenders concentrate on owner-occupied homes. Some limit or decline lines on non-owner-occupied property.

That is why a broker with access to several wholesale lenders matters here. One lender may refuse a rental line outright, while another writes it under stricter terms. You are not looking for a single best name. You are looking for the program that fits your file.

The network’s investment line works as a standalone line in first or second lien position. It can sit behind your existing mortgage or stand alone on a free-and-clear property. It covers single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.

Availability is also narrower than the DSCR footprint. Home equity lines are arranged in a smaller set of states than the 41 markets where Lendmire places DSCR loans, so confirm the state first.

Key Terms Defined

HELOC: A home equity line of credit is a revolving credit line secured by property you own. You borrow against it up to a limit.

Draw period: This is the stretch when you can borrow from the line. On the network’s investment line, it lasts 5 years.

Repayment period: This is the stretch after the draw ends. New borrowing stops and the balance is paid down over time. On the investment line, it lasts 25 years.

CLTV: Combined loan-to-value adds your existing mortgage balance and the new line, then divides by the property’s value. It is the core equity test.

DTI: Debt-to-income compares your monthly debts to your income. It measures you, not the property.

Interest-only payment: During the draw, the payment covers interest on the drawn balance. It does not reduce the principal.

How Does the Interest-Only Draw Actually Work?

During the draw, your payment covers interest on what you have borrowed, and nothing goes toward principal. Experian describes the same mechanic: you borrow during a draw period, often 10 years in the broader market, and pay only interest on the amount drawn. Landlord Studio puts typical market draw periods at 5 to 10 years. The network’s investment line runs the shorter 5-year draw.

Here is the sequence on an investment line:

1. Closing. At least 75% of the line is drawn at closing. Interest starts on that drawn balance.

2. Draw years. You can pay interest only, borrow more, and repay as you like, up to the limit. Pricing floats and never converts to a fixed structure.

3. Payment movement. Because pricing floats, your payment can change even when you draw nothing more.

4. End of draw. The line closes to new borrowing. The balance then amortizes over 25 years.

Interest-only does not mean a smaller loan. It only delays principal. If you draw the full amount and never pay extra, you owe the same balance on the last day of the draw as on the first.

Not every HELOC in the market is interest-only. Some plans build principal into the draw-period minimum, and the structure comes from the plan agreement, not from any rule. The network’s investment line is interest-only during the draw.

What Happens When the Draw Ends?

Your required payment steps up, because principal now enters the payment and is spread over the 25-year repayment. The CFPB’s HELOC booklet warns about this transition. It notes that repayment schedules often run ten or 15 years in the broader market, and that some plans make the full balance due at once as a balloon. The network’s investment line uses a 25-year amortization, so there is no balloon.

Picture an investor whose rental carries 55% of its value in first-mortgage debt. The network’s ceiling on an investment property is 70% CLTV, so the most the line can add is 15 points of value. The investor draws most of it for a renovation and pays interest only for five years. The renovation may support higher rent, but only if the market and the property cooperate.

When the draw ends, that same balance begins to amortize. If rent has not grown enough to absorb the larger payment, the property can go from comfortable to thin. Plan for the exit on day one. Decide whether you will pay down voluntarily, refinance the balance, or sell before the repayment begins.

How Do Lenders Qualify You for an Interest-Only Line?

Lenders review your file on your credit, your debt-to-income, and your equity, not on the property’s rent. Rental income treatment depends on the lender, and debt-to-income limits on rentals are generally tighter than on a primary residence.

On the network’s investment line, the main tests run like this, all subject to lender guidelines and full file review:

• Credit: A 700 minimum applies, and it is a hard floor with no tier beneath it. Scores of 700 and 720 both reach the same 70% CLTV, so a score above 700 adds no extra leverage.
• Credit report details: The lender uses a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows a 4-year path.
• DTI: The maximum is 50%. The lender calculates it on the interest-only payment at the maximum draw, not on your current balance. An undrawn line still counts at full size.
• Equity: Existing mortgage plus the new line cannot exceed 70% of value.
• Valuation: Because an investment line tops out at $500,000, it commonly runs on an automated valuation with no traditional appraisal. A borrower may still request a full appraisal.
• Portfolio limits: You are limited to three lines. An owner with more than 15 financed properties is not eligible.

Documents vary by lender, but expect a mortgage statement, an insurance declaration, vesting documents, a lease, and tax returns and bank statements as the lender requires them.

Which Lender Types Fit Which Borrower?

The right lender type depends on what you hold and how you hold it. This table summarizes how the three common channels tend to differ.

Does Title Matter? The LLC Problem

Title is the sharpest structural limit on this product. On the network’s investment line, the property must be held by you individually or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.

That creates a real dilemma for investors who put rentals in an LLC for asset protection. A property already deeded to an LLC needs a vesting change before a HELOC is possible. Retitling can raise its own questions, so think it through before you change anything. The other route is a DSCR cash-out refinance, which may allow LLC-titled borrowers subject to lender program eligibility.

HELOC or DSCR Cash-Out Refinance?

A HELOC is qualified on you. A DSCR cash-out refinance is qualified primarily on property-level rental income covering the payment, subject to lender guidelines. That difference decides most cases.

DSCR programs across the network typically start at 1.00 coverage, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow, since repairs, vacancy, management, and capex sit outside the calculation.

For the full picture of how these loans work, the complete DSCR loans guide covers requirements, leverage tiers, and structures.

What Are the Risks?

The risks are payment movement, payment shock, and equity that never builds. Floating pricing means the interest-only payment can rise on a thin-margin rental with no new draw. The end of the draw raises the required payment. And because no principal is paid during the draw, interest-only borrowing builds no equity through paydown.

A line with a floating payment and a 5-year interest-only draw suits short holds and bridge uses better than long-term down-payment funding. A rental secures the line, so missed payments put that property at risk. If you borrow against a different property, that one is exposed instead.

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, and IRS Publication 936 explains the use-of-proceeds test.

Who Should Skip an Interest-Only Line?

Skip it if any of these describes you:

• Your rental is held in an LLC and you do not want to retitle it.
• Your credit sits below 700.
• Your debt-to-income already runs near 50%, since the lender tests it on the full draw.
• You need money for a long hold with no exit plan for the repayment step-up.
• You own more than 15 financed properties.
• Your property is a manufactured home, log home, or barndominium, which are not offered.

What to Ask Before You Apply

Come prepared with these questions for any lender or broker:

1. Does the program lend on non-owner-occupied property in my state?

2. What is the maximum CLTV for my occupancy type?

3. How long is the draw, and how long is the repayment?

4. How is my DTI calculated, on the current balance or the maximum draw?

5. How must title be held?

6. How much must be drawn at closing?

7. Is a full appraisal required, or does an automated valuation apply?
