Investment Property HELOC Requirements for Landlords Borrowing Against Rental Income

The Quick Read: An investment property HELOC is a revolving line secured by a rental, written in first or second lien position. Through select wholesale lenders in Lendmire’s network it caps at 70% combined loan-to-value, needs at least a 700 credit score, tops out at $500,000, and must be titled to an individual or revocable living trust, not an LLC. Every figure is subject to lender guidelines and full file review. The line is underwritten mainly on the borrower’s credit, equity and debt-to-income, not on the property’s rent alone.

• Investment lines reach 70% CLTV at both the 700 and 720 credit tiers, so a higher score does not buy more leverage.
• The maximum line is $500,000, and at that size valuation is ordinarily automated rather than a full appraisal.
• The line runs a 5-year interest-only draw followed by a 25-year repayment, and pricing floats throughout.
• LLCs, corporations and land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change or a different product.
• Property-rent-based lender review is a DSCR loan feature. A DSCR cash-out refinance is the usual alternative when title or income structure does not fit a line.

What Makes an Investment Line Different From a Primary-Home Line?

An investment line is a narrower product with a lower ceiling. Fewer lenders write it, the leverage cap is lower, and the credit floor is higher than on a line secured by the borrower’s own residence.

NerdWallet reports a smaller pool of lenders and lower borrowing limits than on a primary home, and it says lenders may want proof of long-term tenants and more than one appraisal. Lofty notes that most major banks do not offer these lines at all. NerdWallet’s market-wide figures put typical credit expectations at 720 or higher and maximum LTV at 80%, with many lenders sitting below 70%. On Lendmire’s network, the investment ceiling is 70% CLTV.

The 90% primary-residence figure exists only at a 720-or-better credit profile. It never applies to a rental. A line above $500,000 is primary-residence only, caps at 75% CLTV and requires a full appraisal.

Key Terms Defined

• HELOC: A revolving line of credit secured by real estate, with a draw period followed by a repayment period.
• CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
• Vesting: The legal form in which title is held, such as an individual, a trust or an LLC.
• DTI (debt-to-income): Monthly debt obligations divided by monthly gross income.
• DSCR (debt service coverage ratio): Monthly rent divided by PITIA, which is principal, interest, taxes, insurance and any association dues.
• Seasoning: The time a borrower has owned the property or held a loan, or the time since a credit event.

How Does Underwriting Treat the Line, Step by Step?

The review runs in a fixed order. A file that fails an early step does not reach the later ones, so check the early steps first.

1. Confirm the collateral and the use. Two different deals get called an investment property HELOC. One is a line on a rental. The other is a line on the owner’s own home used to fund a rental. This article covers the line secured by the rental. The occupancy of the collateral sets which ceiling applies, so state it first.

2. Check title. The rental must sit in the name of the individual borrower or a revocable living trust. Fee simple and leasehold are both acceptable forms of ownership. Entity titles fail here.

3. Size the line against CLTV. Take 70% of the property’s value, subtract the first mortgage and any other liens, and the remainder is the most the line can be. The $500,000 cap then applies on top.

4. Review credit and DTI. The investment floor is 700. DTI tops out at 50%, and the line is qualified on the interest-only payment calculated on the maximum draw. A borrower who plans to draw less is still tested as if the full amount were drawn.

5. Order the valuation. Because an investment line is capped at $500,000, valuation is ordinarily automated. A borrower may request a full appraisal in any case, and a higher CLTV may call for a secondary valuation.

6. Assemble the documents. Expect leases or a rent roll, the current first mortgage statement, proof of insurance, the vesting documents and a credit report no more than 90 days old at closing. NerdWallet’s note about proof of long-term tenants matches what a lender wants to see on lease terms.

7. Understand the draw and repayment. The line has a 5-year draw followed by 25 years of fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats across both phases and never converts to fixed. The CFPB describes the same two-phase structure and warns that monthly payments are often significantly higher once repayment begins.

How Is the Maximum Line Actually Sized?

The line equals the allowed CLTV minus what is already borrowed against the property, expressed in points of value. The $500,000 cap then trims anything above it.

Run the numbers on a rental with a first mortgage equal to 50% of value. At the 70% ceiling, the line can use at most 20 points of value. Now take a rental with a first mortgage at 65% of value. Only 5 points of room remain, which may be too small to be worth the closing effort.

A line can also sit as a standalone first lien on a paid-off rental. In that case the full 70% is available, up to the $500,000 maximum.

Because the cap is $500,000, the property’s value drives which limit binds. A modest-value rental hits the CLTV limit first. A higher-value rental hits the dollar cap first. Check both before ordering anything. The site’s illustrative calculator can help you test combinations, but it is an estimate, not a quote.

Does Rental Income Count?

On a bank-style line, rental income enters the borrower’s DTI, and the line is judged on the borrower’s total profile. The property’s rent is one input. It is not the test.

This is the sharpest difference from a DSCR loan. A DSCR file compares the property’s monthly rent to its PITIA. Many select programs start at 1.00 coverage, and a separate select-lender path goes below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and leverage. The borrower’s personal income is not the main driver of a DSCR file, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Clearing 1.00 is not the same as positive cash flow. DSCR counts rent against PITIA only. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation. A property can clear the ratio and still lose money in a bad month.

A HELOC borrower faces the opposite problem. The rent may be strong, but a high personal DTI can still stop the line. The two products test different things, which is why a rental can fail one and suit the other.

Where Does the General Rule Break?

Most of the exceptions come from title, property type and location, not credit.

• LLC-held rentals. The line cannot be written to an LLC, corporation, partnership, or an irrevocable, blind or land trust. Moving a rental out of an LLC changes liability and may affect insurance, so check with an attorney and an insurance agent before re-deeding. The other route is a DSCR cash-out refinance, which can lend to an LLC subject to lender program eligibility.
• Ineligible property types. The line is not offered on manufactured homes, co-ops, condotels, log homes, commercial, mixed-use or agriculturally zoned property. Single-family, 2-4 units, PUDs, townhomes and condominiums are eligible, including non-warrantable condos. The DSCR programs in the network likewise do not offer manufactured homes, log homes or barndominiums.
• Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas and Washington.
• Texas. The homestead waiting period, the one-lien-at-a-time rule and 12-month seasoning bind primary residences only. A Texas rental is a non-homestead transaction, but the property is limited to 10 acres, and the minimum draw after closing is $4,000 in Texas against $1,000 elsewhere.
• New Mexico and Ohio. The CLTV cap depends on the credit profile in these states.
• Exposure limits. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
• Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure seasons for 7 years, and a deed-in-lieu, pre-foreclosure or short sale seasons for 4.
• Geography. The HELOC is available only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. That is narrower than the DSCR footprint.

HELOC or DSCR Cash-Out: Which Fits?

Choose by what you need to keep and what you can document. A HELOC leaves the first mortgage in place. A cash-out refinance replaces it.

On DSCR cash-out, leverage tops out around 75% LTV across most of the network on a standard rental (70% on short-term-rental collateral), and about 6 months of seasoning is the common expectation. Credit floors run from 620 in parts of the network to about 660 for most programs, with 700 and above unlocking the strongest tiers. Reserves vary by lender, leverage, loan size and transaction type, commonly around 6 months of PITIA. Lendmire arranges these loans across 41 markets, including Washington, D.C. The complete DSCR loans guide covers the full program range.

Lendmire’s piece on borrowing against a rental with an investment property HELOC goes deeper on the line itself.

Stress-Test Before You Draw

Pricing on the line floats and the draw is interest-only for five years, so the payment changes at two points: when pricing moves and when repayment begins. Test the plan against both.

Run a simple self-check. First, ask whether rent covers the first mortgage and the line together if the unit sits vacant for a stretch. Second, ask whether the plan still works if repayment started today. Third, ask whether reserves cover both obligations through a renovation and lease-up. If the answer to any is no, draw less or choose a structure with fixed terms.

Using draw proceeds as a down payment on the next purchase adds the line payment to a property that may not be producing rent. The DSCR on the new purchase does not include the HELOC payment, but your cash position does.
