Investment Property HELOC Requirements Against a Rental You Already Own

The Quick Read: You can borrow against a rental you already own with a home equity line, but the market is narrow. On Lendmire’s wholesale network, an investment-property line tops out at 70% combined loan-to-value (CLTV, meaning all loans on the property divided by its value), needs a 700 credit score, caps at $500,000, and must be titled in your name or a revocable trust, not an LLC. Every figure is subject to lender guidelines and full file review.

• Leverage: 70% CLTV is the ceiling on an investment line, whatever your credit above 700.
• Credit: 700 is a hard floor on an investment-property line. No lower tier exists for this product.
• Title: Individual or revocable living trust only. An LLC-owned rental needs a different route.
• Valuation: Lines at this size usually use an automated valuation, not a full appraisal.
• Alternative: A DSCR cash-out refinance is a separate product that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Key Terms Defined

Lien: a lender’s legal claim on a property. A first lien gets paid before a second lien.

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

Vesting: how title to the property is held, such as your personal name, a trust, or an LLC.

Automated valuation: a computer-generated value estimate that replaces a traditional appraisal.

DSCR: debt service coverage ratio. It compares a property’s monthly rent to its monthly payment of principal, interest, taxes, insurance, and any association dues.

Seasoning: the waiting period a lender wants after you buy or refinance before it will lend again.

Which HELOC Are We Talking About?

Two different products get confused under one name. One is a line secured by your primary home, used to fund a rental. The other is a line secured by the rental itself. This article covers the second one.

The difference matters because of what you put at risk. With a line on your home, the home is the collateral. With a line on the rental, the rental is. Underwriting also changes. The lender looks at the rental’s equity, its eligibility, and your personal credit and debt load.

Availability is thin. NerdWallet notes that not every lender offers investment-property lines and that qualification is strict. Some lenders also limit these lines by location and by whether the home is rented year-round. White Coat Investor adds that large national banks tend to have stricter eligibility.

Lendmire is a broker, not a lender. It places these lines with select wholesale partners, and a lender reviews and approves each file. For this home equity product, availability is limited to 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. Lendmire’s separate DSCR loan programs cover a wider footprint.

How Underwriting Treats a Rental Line, Step by Step

Underwriting runs as a series of gates. Fail one and the rest do not matter. Here they are in order.

Step 1: Title. The property must be held by you personally or by your revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. If your rental is already deeded to an LLC, you need a vesting change first, or a different product.

Step 2: Property type. Eligible: single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Not eligible: manufactured homes, co-ops, condotels, log homes, commercial or mixed-use property, and agriculturally zoned land. A property listed for sale, or listed within the past 60 days, is also ineligible in NC, PA, TN, TX, and WA.

Step 3: Equity. The lender takes the property’s value, applies the 70% CLTV ceiling, and subtracts every existing lien. What remains is the most the line can be, and it never exceeds $500,000.

Step 4: Credit and debt load. You need at least a 700 score, using a single-bureau model keyed to the primary wage earner. The credit report can be no more than 90 days old at closing. Your debt-to-income ratio (DTI) can run to 50%, and the lender tests it on the interest-only payment calculated on the maximum draw. That is the full line, not just what you plan to borrow.

Step 5: Rental documentation. Lenders commonly ask for leases, a rent roll, and prior tax-return rental schedules. How much of the rent counts toward your income is the lender’s call. Do not assume full credit. Rent is not counted the way it is on a DSCR loan.

Step 6: Credit history. 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.

What Does the CLTV Math Look Like?

Run the numbers on a rental valued at 100 units of value. The 70% ceiling allows total debt of 70 units. If the first mortgage sits at 50, the line can be at most 20 units. If the first mortgage sits at 60, only 10 units remain. A paid-off rental can support the full 70, though the line is still capped at $500,000.

And 70% is the network ceiling for an investment property. Lenders may advertise higher figures, and those do not apply here.

Here is how an investment line compares with one on a primary residence, on this network.

Above $500,000, a primary-residence line also caps at 75% CLTV and requires a full appraisal. None of that applies to a rental.

What Happens After You Close?

An investment line runs a 5-year interest-only draw period, then a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing, so this is not a pot of cash you leave untouched. You carry payments on most of it from day one. Qualification uses the interest-only payment calculated on the maximum draw, so your debt-to-income ratio is tested against the full line, not just the amount drawn.

Pricing floats with an index through both the draw and repayment periods and never converts to fixed. The CFPB’s HELOC explainer describes the same general structure on consumer lines: a draw period, then repayment, with a variable cost that can change your payment. Some lenders in the wider market let you convert part of the balance to fixed. That option is not part of this program.

Stress-test two things before you sign. First, the payment steps up when amortization begins after year five. Second, the payment moves with the index even if you draw nothing more. If a vacancy or a rent cut leaves little cushion today, floating pricing can erase it.

Reserves matter too. An unused line generally does not count as reserves, and a drawn balance is simply more debt. Plan for the reserve requirement on your next purchase separately.

Where the General Rule Breaks

Portfolio size. A borrower is limited to three lines. Anyone owning more than 15 financed properties is not eligible, and combined-exposure limits also apply by program.

Short-term rentals. Lendmire’s guidelines set no separate rule for short-term rentals, so the same investment-line limits apply, and eligibility can still differ by program and lender. Short-term rental rules also vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.

Recently bought or refinanced. Lenders may want seasoning on a recent purchase or refinance. Ask about the waiting period before you apply.

Low credit. A score below 700 does not work on an investment line. The path forward is a different product, not a workaround.

Valuation. Because the line cannot exceed $500,000, it normally runs on an automated valuation with no traditional appraisal. A higher CLTV may trigger a secondary valuation, and you can request a full appraisal in any case.

When a DSCR Cash-Out Refinance Is the Better Tool

If you fail the title, credit, or leverage gate, a DSCR cash-out refinance is the usual alternative. It replaces your first mortgage rather than adding a second lien, and it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire arranges DSCR programs in 41 markets, including Washington, D.C. The complete DSCR loans guide covers how those loans work.

Know the tradeoffs. DSCR coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Cash-out typically wants about 6 months of seasoning and often about 6 months of reserves. Reserves vary by lender, leverage, and loan size.

Clearing 1.00 does not mean positive cash flow. DSCR compares rent to the mortgage payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.

The right choice often comes down to your existing first mortgage. If it is a good one, a second-lien line lets you keep it. If you need more equity than 70% allows, or the rental sits in an LLC, the refinance is the realistic path. Lendmire’s piece When an Investment Property HELOC Makes Sense on a Single-Family Rental You Already Own goes deeper on the single-family case.

What If You Don’t Pass a Gate?

• Title fails: Move the property out of the LLC where that makes sense, or go DSCR.
• Credit fails: Build the score past 700, or use a DSCR loan, where a 620 floor exists in parts of the network.
• Equity fails: Wait, pay down the first mortgage, or look at a cash-out with a different structure.
• Property type fails: Those property types are not offered on these lines. Do not plan around them.
