How an Investment Property HELOC Works for an Equity-Rich Landlord

The Quick Read: This is a revolving credit line secured by a rental you own. Through the select lenders Lendmire works with, it tops out at 70% combined loan-to-value (CLTV) on an investment property, with a 700 minimum credit score, a $500,000 maximum line, and underwriting that looks at you rather than the rent. Most of the line is drawn at closing, so it works more like a flexible loan than a standby account.

• Leverage: On an investment property, the ceiling is 70% CLTV, and a 700 or 720 score reaches the same tier.
• Size: Investment lines run from $25,000 to $500,000. Bigger lines are limited to primary residences.
• Underwriting: Your credit, debt-to-income ratio and the whole file drive approval. Rent coverage is not the test.
• Title: The property must be in your personal name or a revocable living trust. An LLC cannot hold title.
• Payments: The line is interest-only for five years, then amortizes over 25 years. Pricing floats and never converts to fixed.

What an Investment Property HELOC Actually Is

A home equity line of credit (HELOC) lets you borrow against what you own in a property. The line is revolving: you borrow, repay and borrow again within the limit. The CFPB describes it as an open-end line with a draw period followed by a repayment period.

Most consumer HELOC material assumes the collateral is the home you live in. A line on a rental is a narrower product. Many banks that offer lines on primary residences decline rentals, and BiggerPockets notes that some lenders label rental lines as business or commercial credit lines rather than true HELOCs. NerdWallet adds that not every lender offers them and that qualification is strict.

Lendmire is a broker, not a lender. It places these lines with select wholesale partners. Availability is limited to 16 full-service states, which is narrower than its 41-market DSCR footprint, and every file is subject to lender guidelines and full review.

Key Terms Defined

CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.

Draw period: The stretch when you can borrow against the line and pay interest only.

Repayment period: The stretch after the draw ends, when the balance amortizes into regular principal-and-interest payments.

Lien position: Where the lender sits in line for payment if the property is sold or foreclosed. The line can sit first or second.

Vesting: How title is held, such as your own name or a revocable living trust.

DSCR (debt service coverage ratio): Monthly rent divided by the full monthly housing payment: principal, interest, taxes, insurance and any HOA dues. A DSCR loan is underwritten on that property-level number.

How Underwriting Treats the Line, Step by Step

Step 1: The equity test. The lender applies the 70% CLTV ceiling to the property’s value. It subtracts what you already owe on the first mortgage. What remains is the most the line can be, before the $500,000 cap.

Say a rental is valued at 100% and your first mortgage equals 40% of that value. A 70% ceiling leaves room for a line worth 30% of the value. That is why a large amount of equity on paper does not translate into a line of the same size. The CFPB booklet shows the same subtraction method.

Step 2: Valuation. Because an investment line cannot exceed $500,000, it sits in the automated valuation lane. Many files close with no traditional appraisal. You can request a full appraisal in any case. A higher CLTV may call for a second valuation. Lenders outside this network may order multiple appraisals, as NerdWallet notes.

Step 3: You, not the rent. The lender reviews your credit, your debt-to-income ratio (DTI) and your housing history across every property you finance. DTI tops out at 50%. The lender calculates it on the interest-only payment at the maximum draw, not on what you plan to borrow. The rent on the collateral property matters mainly as part of your overall financial picture.

Step 4: Credit. The general program floor is 600, but investment lines are held to a higher standard. They start at 700, and that is a hard floor with no tier below it. Scores of 700 and 720 both reach 70% CLTV, so a higher score buys eligibility rather than extra leverage. The lender uses a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing.

Step 5: Documents and setup. Expect to provide leases, proof of insurance, a mortgage statement and title documents. The line is then set up as a standalone line in first or second lien position. A first mortgage can stay in place.

Step 6: Draw and repayment. At least 75% of the line is drawn at closing. After closing, each additional draw has a minimum of $1,000 in most places. Investment lines use one structure: five years interest-only, then 25 years of fully amortizing repayment.

The Draw-to-Repayment Cliff

The payment is not constant. During the five-year draw, you pay interest only, so the payment is as low as it will ever be on that balance. When the repayment period begins, principal gets added to every payment for the remaining 25 years.

Pricing floats across both periods and never converts to fixed. That means two things can change the payment at once: the index and the amortization. A landlord who sizes the draw to fit today’s interest-only payment may find the repayment period much tighter.

Where a first mortgage exists, the line sits behind it as a second mortgage. Underwrite the property as if the amortizing payment already applies.

BiggerPockets suggests a simple test in its Rookie episode on HELOCs: ask whether the rental you’re buying with the money can cover its own mortgage, its own expenses and the line payment.

Title and Vesting: Where Landlords Get Stuck

Here is the sharpest structural difference from a DSCR loan. Title must be held by you as an individual or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title.

Many experienced landlords hold rentals in LLCs. If your property is already deeded to one, you have two options: change the vesting before applying, or use a DSCR cash-out refinance instead, which can work with LLC-titled properties subject to program terms. Check with your attorney before you move title. Moving a deed can trigger other issues with your existing lender and insurance.

Where the General Rule Breaks

The 70% ceiling and 700 floor apply broadly, but several edge cases change the answer.

• Property type. Single-family homes, 2-4 units, PUDs, townhomes and condos are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agriculturally zoned properties are not offered.
• Number of lines. A borrower is limited to three lines. Combined exposure on investment lines caps at $750,000, which is a separate limit from the line count.
• Portfolio size. Separately from that dollar cap, a borrower who owns more than 15 financed properties is not eligible.
• Listed properties. In several states, a property that is listed for sale, or was listed in the past 60 days, is ineligible.
• Credit events. A bankruptcy needs four years of seasoning from discharge or dismissal. Investment files season a foreclosure at seven years, and a deed-in-lieu, pre-foreclosure or short sale at four.
• Primary-home equity. Borrowing against the home you live in can reach up to 90% CLTV, but only at a 720 or better credit profile. A line above $500,000 is primary-residence only. Investment properties never get those tiers.

Rental Equity, Home Equity and DSCR Cash-Out Compared

The right tool depends on what you hold and what you need.

A DSCR cash-out tops out around 75% LTV on standard rentals and 70% on short-term-rental collateral, with about six months of seasoning as the common expectation. DSCR loans qualify primarily on property-level rental income covering the payment, subject to lender guidelines. For a deeper side-by-side, see Lendmire’s piece on how an equity line compares with a DSCR cash-out for an equity-rich landlord.

On coverage, 1.00 is where many select programs start. 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. Repairs, vacancy, management and capital expenses sit outside the calculation.

Which Landlord Are You?

The landlord with a low-cost first mortgage and a defined project. Keeping that first loan in place is the main reason to choose a line. The 70% ceiling and the mostly drawn balance at closing mean you need a use for the money now.

The landlord with an LLC portfolio. The line is probably the wrong product unless you are willing to change title. A DSCR cash-out is built for this holding structure.

The landlord who wants standby liquidity. Be careful. Since at least 75% of the line is drawn at closing, you will pay on most of it from day one. A true standby reserve is a different product.

The landlord who needs more than $500,000. An investment line cannot exceed that amount. Use a cash-out refinance or a line on a primary residence, if you have one.

The landlord with thin equity. At 70% CLTV, little room remains after a first mortgage at 60% or more of value. The line may be too small to justify the setup.

Using the Line

Common uses include renovations, a down payment on the next property, and staged projects where you draw for the work and then refinance into permanent debt. BiggerPockets coverage also describes recycling funds across rentals. That means drawing, buying, refinancing and repaying the line.

Under this program, you can’t count on the line staying as large as you got it. Lenders can reduce a line if the property’s value falls. A sale of the property generally means the line is paid off at closing.

When Not to Use It

Skip the line when your rentals sit in an LLC you do not want to move. Skip it when your score is under 700, since investment lines have no tier beneath that. Skip it when your DTI is already near 50%, because the lender tests it on the maximum draw.

Skip it when the project depends on cheap long-term pricing. A floating line that amortizes after five years is not a long-term hold. In that case, the DSCR cash-out refinance is the more natural fit.
