Investment Property HELOCs for Buy-and-Hold Owners Needing a Revolving Line

The Quick Read: A line of credit on a rental lets a landlord keep the existing first mortgage in place while borrowing against equity. On the wholesale network Lendmire places files with, the line is capped at 70% combined loan-to-value, tops out at $500,000, and is drawn at least 75% at closing. That makes it work more like a floating-price second loan than an idle reserve.

• The ceiling on an investment line is 70% combined loan-to-value, with a 700 minimum credit score and a $500,000 maximum line.
• The structure is a 5-year interest-only draw followed by a 25-year repayment, with pricing that floats throughout and never converts to fixed.
• The borrower must hold title personally or in a revocable living trust. An LLC cannot hold title on these lines.
• A DSCR cash-out refinance is the usual alternative when the title sits in an LLC, the portfolio is large, or the rent is the stronger part of the file.

What an Investment Property HELOC Actually Is

A home equity line of credit is a revolving loan secured by property equity. The borrower draws, repays, and can draw again up to a limit. On a rental, the collateral is an investment property instead of a primary residence.

Most banks treat these lines as a niche product. NerdWallet notes that not every lender offers them, that qualification is strict, and that more than one appraisal may be required. Market surveys also report investment-property lines up to 80% loan-to-value, with many lenders sitting below 70%. Those are market-wide statistics. The ceiling on the network’s investment line is 70% combined loan-to-value, and no tier sits above it.

Buy-and-hold owners tend to want the line for three reasons:

• To keep a low-cost first mortgage untouched.
• To hold a standing source of down-payment money.
• To fund improvements across several properties without refinancing each one.

Each of those goals bumps into the structure described below.

How Underwriting Treats the Line, Step by Step

A line on a rental is underwritten mostly on the borrower, not the rent. That is the biggest difference from a DSCR loan. Here is the sequence a file follows.

Step 1: Equity sizing. The lender takes the property value, applies the 70% combined ceiling, and subtracts every lien already on the property. If a rental carries a first mortgage at 50% of its value, that leaves room for roughly 20% of value in a new line. A first mortgage at 60% leaves about 10%. The line also has a $500,000 cap and a $25,000 minimum.

Step 2: Valuation. Because an investment line cannot exceed $500,000, it sits in the automated-valuation lane. Most files close with no traditional appraisal, though a higher combined ratio can trigger a secondary valuation. A borrower can also ask for a full appraisal.

Step 3: Credit. The floor on an investment line is 700. Scores of 720 and 700 both reach the same 70% ceiling, so a higher score buys eligibility rather than extra leverage. The network scores the primary wage earner on a single-bureau model, and the report cannot be more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.

Step 4: Debt-to-income. Maximum debt-to-income is 50%. The lender qualifies the borrower on the interest-only payment calculated on the full line, not on the amount drawn. A $500,000 line is therefore tested as if fully drawn. NerdWallet adds that rental income can support a higher ratio at some lenders, but only part of that income may count.

Step 5: Property and title. The property must be a single-family home, a 2-4 unit building, a PUD, a townhome, or a condominium. Non-warrantable condominiums are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.

Step 6: Reserves and exposure. Lenders want cash reserves and proof the property is rented. The White Coat Investor makes the same point about market lenders. A borrower can hold no more than three lines, and an owner with more than 15 financed properties is not eligible.

Every figure here is subject to lender guidelines and a full file review. None of it is a commitment to lend.

Key Terms Defined

Combined loan-to-value (CLTV): The total of all liens on a property, divided by its value.

Draw period: The stretch when the borrower can borrow against the line, here the first 5 years on an investment line.

Repayment period: The stretch after drawing ends, when the balance is paid down over a set term, here 25 years.

Lien position: Where a loan ranks in a payoff. A first lien is paid before a second lien.

Automated valuation: A computer-based property value estimate used in place of a full appraisal.

DSCR: The monthly rent divided by the full monthly housing payment, which includes principal, interest, taxes, insurance, and any association dues.

Why “Revolving” Is Narrower Than It Sounds

The word revolving suggests a pool of cash that sits unused until needed. On this network, the investment line does not behave that way. At least 75% of the line must be drawn at closing, and interest accrues on that drawn balance from day one.

After closing, the borrower can draw again in minimum increments of $1,000. They can repay and redraw during the 5-year draw period. Pricing floats across both the draw and the repayment period and never converts to a fixed structure.

Picture an owner who wants a standing reserve against vacancies. A line drawn mostly at closing is the wrong tool, because the borrower is paying on most of it before the first vacancy shows up. The same owner would do better keeping a small line or a cash buffer. A different owner has a defined project, such as renovating a duplex, and wants to use most of the line right away. For that owner the 75% draw rule costs nothing.

The question to ask is whether the money has a job on day one.

The Payment Step-Up Nobody Plans For

Once the 5-year draw ends, the line enters a 25-year amortizing repayment period. The payment shifts from interest-only to principal and interest. The CFPB describes the same pattern for home equity lines in general: borrowing stops, repayment starts, and monthly payments are often significantly higher. It also warns that falling behind can cost the borrower the home that secures the line.

A buy-and-hold owner should map that date against the portfolio. Which leases roll then? Which first mortgages reset? If three properties each carry a line and all three step up in the same year, the combined jump matters more than any single payment. The floating price adds a second moving part, since the payment can change even during the interest-only years.

Structures and Variations That Exist

The line itself comes in a few forms, and the right one depends on the collateral and the borrower’s title.

The investment line. This is first or second lien on the rental, at 70% combined, $500,000 maximum, with the 5-year draw and 25-year repayment described above.

The primary-home line. A line secured by the owner’s own residence is a different product with different leverage. On a primary residence the ceiling reaches 90% combined loan-to-value, but only at a 720-or-better credit profile. Many landlords use this path to fund a rental purchase. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

Lien position. The investment line can sit in first or second position. Most owners with an existing mortgage will be in second position, which preserves the first mortgage. An owner with a free-and-clear rental can place the line in first position.

Where the General Rule Breaks

A few edge cases decide whether this product is available at all.

LLC title. This is the sharpest break. The line requires fee simple or leasehold title held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change or a different loan. Retitling can carry its own consequences with the existing first mortgage, so that step is worth reviewing before it is taken. A DSCR cash-out refinance, by contrast, can fit entity-owned property, subject to lender program eligibility.

The DSCR HELOC nickname. The phrase is a market nickname, not a standard product. A quote described that way might be a rent-qualified first-lien cash-out, a closed-end second lien, or a personally underwritten revolving line. Before comparing quotes, ask which one is on the table. The three behave very differently on rent coverage, title, and the first mortgage.

Portfolio size. The three-line limit and the 15-property ceiling mean a growing portfolio runs out of room. The personal debt-to-income test also tightens with every loan added to the file. This is the main reason investors with many financed properties move to rent-based financing.

Property type. Manufactured homes, log homes, and barndominiums are not offered on these lines or in the DSCR programs on the network. An owner with a mixed portfolio may find only some of it eligible.

Geography. These lines are available only in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint.

HELOC or DSCR Cash-Out? How the Decision Looks

The trade-off is simple to state. A line leaves the first mortgage alone and tests the borrower. A DSCR cash-out replaces the first mortgage and tests the property’s rent.

On the DSCR side, cash-out refinances top out around 75% loan-to-value on standard rentals across most of the network. About 6 months of seasoning is the common expectation. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. Coverage of 1.00 is where select programs start. A separate path through select lenders in the network goes below 1.00, with leverage and terms adjusted. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA.

Clearing 1.00 does not mean the property cash-flows. The ratio compares rent to the full housing payment only. Repairs, vacancy, management, and utilities sit outside it.

Three owner profiles show where the choice flips:

• A personal-name owner with one or two rentals and a strong first mortgage. The line usually fits. It leaves the first loan untouched and adds funds in second position.
• An LLC-held portfolio. The line is off the table without retitling, so the DSCR cash-out becomes the working path.
• An owner with a moderate first mortgage who needs a large sum. The $500,000 cap and 70% ceiling may bind, which pushes the file toward cash-out.

The overview in the complete DSCR loans guide covers the rent-based alternative in detail.

Practitioner Notes From Placing These Files

Across the wholesale network, the files that stall tend to share a pattern. The borrower asks for a revolving reserve, then learns the draw rule and the title rule at the same time. Sorting out title and purpose before a quote request saves the most effort. Owners who hold property in an LLC for liability reasons should settle that tradeoff first. A line is only useful if the title can legally carry it.

Owners who want to take out most of their equity face a separate set of limits.

Before You Apply

• Confirm whether the property sits in your name, a revocable trust, or an LLC.
• Pull the first-mortgage balance and estimate combined loan-to-value against the 70% ceiling.
• Decide what the money will do on day one, given the 75% draw requirement.
• Check your credit against the 700 floor.
• Map the date the draw period ends against your lease and refinance calendar.
• Count your financed properties and open lines against the three-line and 15-property limits.

Investors who plan to use a rental’s projected short-term income to support the file should know that lines on this network are underwritten on the borrower’s credit and debt load, so projected rental income is not the main test.
