How Much Can You Borrow on an Investment Property HELOC to Retire Business Debt?

The Quick Read: Usually you can borrow up to 70% combined loan-to-value on an investment property through select lenders in Lendmire’s wholesale network, minus every lien already on the rental, capped at $500,000, and your business debt balance does not change that math, because equity, credit, and personal debt ratios set the line.

• The formula: property value × 70% combined loan-to-value (CLTV), minus the first mortgage and any other liens.
• The ceiling: lines run from $25,000 to $500,000, with a 700 minimum credit score on an investment property.
• The title rule: the rental must be owned by you personally or by your revocable living trust, not an LLC.
• The debt test: your personal debt-to-income ratio can run up to 50%, tested on the interest-only payment at the maximum draw.
• The draw rule: at least 75% of the line is drawn at closing, so size the line close to the debt you plan to retire.

A line like this swaps unsecured business debt for debt secured by your rental. That can make sense, but it deserves a clear look at the tradeoffs below.

How the Borrowing Limit Is Calculated

The limit is a short chain of arithmetic. Take the property’s value, multiply by the maximum CLTV, subtract what is already owed against the property, and then compare the result to the program’s dollar cap. The lower number wins.

CLTV means combined loan-to-value. It adds every loan secured by the property, including the new line, and divides by the property’s value. A first mortgage at 50% of value leaves room for a new line of up to 20% of value at a 70% ceiling.

Across Lendmire’s wholesale network, the investment-property ceiling is 70% CLTV. That figure does not rise with a better credit score. A 720 score and a 700 score reach the same 70% on an investment property, so credit above 700 buys eligibility rather than extra leverage. Below 700, the investment-property line is not offered.

Primary residences and second homes can reach higher ceilings. Those tiers do not apply to a rental, and a rental should never be sized with them. NerdWallet notes that a HELOC on a rental is possible but that fewer lenders offer one, and that borrowing limits are usually lower than on a primary home.

The dollar cap is the second gate. Lines on an investment property run from $25,000 to $500,000. Lines above $500,000 exist only on primary residences, so a rental never reaches that tier.

Worked Example in Percentages

These scenarios use percent of property value only. They show how room under the ceiling changes with the first mortgage.

Plenty of equity on paper can still leave too little room for a line worth opening. A free-and-clear rental worth well over $700,000 hits the dollar cap before it hits the CLTV ceiling.

What the Lender Checks Besides Equity

A HELOC is personal debt. The lender reviews you, your credit, and the property’s equity, and it does not test whether the rent covers the payment. That is the biggest structural difference from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Here is what the review covers on an investment-property line:

• Credit: a 700 minimum, which is a hard floor with no lower tier.
• Debt-to-income (DTI): up to 50%, calculated on the interest-only payment at the maximum draw, not on what you plan to draw.
• Valuation: lines of $500,000 or less ordinarily use an automated valuation with no traditional appraisal. You can still request a full appraisal.
• Property type: single-family homes, 2-4 unit buildings, townhomes, PUDs, and condos, including non-warrantable condos.
• Not offered: manufactured homes, co-ops, condotels, log homes, commercial or mixed-use properties, and agricultural zoning.
• Exposure: up to three lines per borrower, and borrowers with more than 15 financed properties are not eligible.

Whether a business obligation counts in your personal DTI depends on how it is reported and whether you guaranteed it. The lender decides that during file review.

Two quirks matter for business owners. A fresh renovation can throw off an automated value, since the model may not see the work. And in some states, a property listed for sale within the past 60 days is ineligible. Both are worth raising before you apply.

Does the Size of the Business Debt Change the Limit?

No. The debt you want to retire does not enter the sizing formula. A rental with room for a $150,000 line gives you the same line whether you owe the creditors a little or a lot.

The reverse is not true, because the draw rule works against oversizing. At least 75% of the line is drawn at closing. Pricing on the line floats through both the draw period and the repayment period, and it never converts to a fixed structure. Drawing money you do not need means paying on money you do not need.

So the practical move is to size the line to the debt, within the cap. List your balances first. Then compare the total to the room the formula gives you.

What If the Debt Is Bigger Than the Line?

Then you have a gap, and the cap does not bend. Say the formula gives you room for a line that covers only part of what you owe. You have four honest options.

1. Retire the most expensive or most dangerous debt first. Merchant advances and high-balance revolving cards usually come before a term loan with a steady schedule.

2. Use a DSCR cash-out refinance. It replaces your first mortgage, and the loan size runs up to $3,000,000 on standard programs (smaller balances available through select lenders). On standard rentals it tops out around 75% LTV across most of the network, and around 70% on short-term-rental collateral. About six months of seasoning is the common expectation.

3. Refinance the business debt at the business level. A business term loan or business line looks at business financials, not your rental’s equity.

4. Pay down in stages. Retire part of the debt now and the rest as cash flow allows.

DSCR means debt service coverage ratio. It divides the monthly rent by the full monthly payment on principal, interest, taxes, insurance, and any association dues (PITIA). A DSCR of 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger coverage opens better pricing and leverage.

One caution on the DSCR route. Clearing 1.00 does not mean the property produces positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.

DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.

HELOC vs DSCR Cash-Out at a Glance

A DSCR loan can close in an LLC, subject to lender program eligibility. A HELOC cannot. The complete DSCR loans guide covers the full program range.

Across Lendmire’s network, a DSCR cash-out also solves the lien-order problem. A DSCR loan generally wants to be the first lien, so it is awkward to place behind an existing HELOC. If you may refinance the long-term debt later, plan the order before you open a second lien.

When the Rental Sits in an LLC

An investment-property HELOC cannot be held by an LLC, corporation, partnership, or an irrevocable, blind, or land trust. Title must sit with you personally or with your revocable living trust. This is the sharpest structural gap between a HELOC and a DSCR loan.

If your rental is already deeded to an LLC, you have two paths. You can change the vesting, which means moving title out of the LLC and into your name or trust. Or you can use a DSCR cash-out refinance instead. Moving title can affect your existing mortgage, insurance, and liability setup, so settle those questions with your lender and advisors before you sign any deed.

The Risks of Swapping Unsecured Debt for Secured Debt

Paying off business cards or loans with a HELOC changes the nature of the debt. Before the payoff, a missed payment may hurt your credit and invite collection. After it, a missed payment puts the rental itself at risk. The Consumer Financial Protection Bureau describes a HELOC as an open-end line with a draw period followed by a repayment period, and it warns that you could lose your home if you cannot repay on schedule.

The same logic applies to a rental. Weigh four risks:

• Floating pricing. The line’s pricing moves over time. The CFPB’s HELOC booklet says home equity lines typically carry variable rather than fixed pricing, and that matches how this network’s lines work.
• Payment step-up. The 5-year draw is interest-only. When the 25-year repayment period starts, the payment includes principal.
• Used-up leverage. A second lien consumes combined leverage that a later cash-out refinance would want.
• Sale payoff. A line secured by the rental has to be repaid when the property sells.

Re-accumulation is the quiet risk. If the business cash flow that built the debt has not changed, new debt can build again. Fix the cause before you clear the balance.

The Payoff Checklist

1. List every debt. Write down the creditor, balance, and payoff figure for each card, advance, or loan.

2. Confirm title. The rental must be in your name or your revocable living trust.

3. Compute room. Value × 70% minus existing liens, then check the $500,000 cap.

4. Check credit and DTI. You need a 700 score and a DTI at or under 50%.

5. Draw into a dedicated account, or pay creditors directly. Keeping the money separate leaves a clean paper trail.

6. Close the retired accounts or lower their limits. An open card with a zero balance is an invitation to run it back up.

7. Set the repayment plan. Budget for the repayment period before the draw period ends.

The checklist works in that order for a reason. Equity and title are cheap to check and expensive to get wrong. Run them before you gather payoff letters.

Key Terms Defined

CLTV (combined loan-to-value): the total of all loans secured by the property, divided by its value.

Lien position: the order in which lenders get repaid from the property if it is sold or foreclosed. An investment HELOC can sit first or second.

Draw period: the stretch when you can borrow from the line. Here it is five years, interest-only.

Repayment period: the stretch after the draw period, when the balance amortizes. Here it runs 25 years.

DTI (debt-to-income): your monthly debt payments divided by your monthly income.

Automated valuation: a computer-generated property value used in place of a full appraisal.

Vesting: how title is held, such as in your name, in a trust, or in an LLC.
