How Much Can You Borrow on an Investment Property HELOC on Business Deposits?

The Quick Read: Usually up to 70% combined loan-to-value on an investment property, with a maximum line of $500,000, and the property’s equity sets that ceiling, not the size of your business deposits. Deposits only help you prove income and debt-to-income, and the tighter of the equity test and the borrower test is the one that limits the line.

• Collateral test: value × 70% CLTV, minus every lien already on the property, capped at $500,000.
• Borrower test: a 700 minimum credit score on an investment line, with debt-to-income at 50% or lower.
• Deposits: they are converted to qualifying income after adjustments, so they never raise the cap.
• Title: an LLC cannot hold title on this product; the borrower or a revocable living trust must.
• Draw rule: at least 75% of the line is drawn at closing, so this is not a standby line.

Qualification is subject to lender guidelines and full file review, and nothing here is a commitment to lend.

How Is the Maximum Line Calculated?

The maximum line is property value times the combined loan-to-value ceiling, minus every lien already on the property. On Lendmire’s wholesale network, that ceiling is 70% CLTV on an investment property. The line also stops at $500,000, whichever comes first.

Consumer HELOC guidance describes the same arithmetic: the CFPB’s HELOC booklet explains that lenders take a percentage of the appraised value and subtract the mortgage balance. A rental works the same way, only with a lower percentage.

Percentages make it concrete. Say a rental’s first mortgage equals 45% of its value; the 70% ceiling then leaves room equal to 25% of value for the new line. With a first mortgage at only 20% of value, the room grows to 50% of value, and on a high-value, low-debt rental the $500,000 cap is reached before the 70% ceiling is.

Two details change the math in practice:

• Unused credit counts. Combined leverage is measured against the full line, drawn or not, so a line you plan to use lightly still consumes room.
• Existing liens include everything recorded. A second mortgage or a prior equity line comes off the top before this line gets any room.

The network places these lines in first or second lien position. That matters because some lenders in the broader market only write a first-lien line on a rental, which can force a payoff of the existing mortgage.

Do Business Deposits Raise the Limit?

No. Deposits answer one question: does your income support the debt? They do not touch the collateral test. A borrower with very strong deposits and thin equity still hits the 70% ceiling. A borrower with deep equity and modest deposits still has to clear the debt-to-income test.

For self-employed investors, deposit-based qualifying helps because tax-return write-offs can shrink reported income. Across the network, the bank-statement approach generally works like this:

1. Gross deposits are totaled from business or personal statements over the review period.

2. Non-income items such as transfers between accounts, loan proceeds, owner contributions and refunds are removed.

3. An expense factor is applied to business-account deposits, because deposits are revenue, not profit. A profit-and-loss statement from a tax professional can support or replace that factor.

4. Ownership share is considered, since you can only count the portion of the business you own.

5. The result is qualifying income, tested against your debts.

Commingled personal and business accounts make step two harder, because the underwriter has to read every transfer. Volatile or declining deposits, or a newer business, can also weaken the file.

This is a documentation method, not a shortcut. The borrower is reviewed on documented income under the applicable program, subject to lender guidelines.

On the credit side, business bank accounts need a 680 minimum for the deposit analysis. An investment line already floors at 700, so bank-statement income is rarely the limiting factor on this product. Credit and equity usually decide it first.

What Else Limits the Amount?

Several tests apply to an investment HELOC, and the line can be no larger than the tightest of them allows. The table lists them in full, and equity and the borrower’s profile are the two that decide most files.

Credit above 700 buys eligibility, not leverage. Both the 720 and 700 tiers reach the same 70% CLTV on an investment property, up to $500,000, so a higher score does not enlarge the line.

Debt-to-income runs on the interest-only payment calculated on the maximum draw, not the amount you plan to use. A borrower who intends a small draw is still tested on the full line.

For context, NerdWallet’s guide to investment-property HELOCs reports that lenders view rentals as higher default risk and that investment lines often call for 720-plus credit. That is a market-wide description. On Lendmire’s network the investment floor is 700, with a 70% CLTV ceiling and a $500,000 maximum line.

Why Is a Rental Line Smaller Than a Primary-Home Line?

Lenders treat a rental as riskier collateral, so they cap leverage lower. On the same network, a primary-residence or second-home line can reach 90% CLTV, but only with a 720 or better credit profile. An investment property tops out at 70%, with no tier above it.

An investor who assumes the primary-home ceiling will overestimate usable equity by a wide margin. The better habit is to compute usable equity at 70%, not at 100% of equity.

Structure, Valuation and Property Rules

The investment structure is a standalone line with a 5-year interest-only draw followed by a 25-year fully amortizing repayment period. The network places these lines through two wholesale programs: a higher-leverage program and a longer-runway program. Investment lines run the longer-runway structure only, so the shorter 3-year draw does not apply to a rental.

Three program facts shape how the line behaves:

• Minimum draw at closing: at least 75% of the line is drawn at closing.
• Pricing behavior: pricing floats across both the draw and repayment periods and never converts to fixed.
• Subsequent draws: the longer-runway program sets a $1,000 minimum for each later draw.

That 75% rule is the one most investors miss. It means the line works more like a second mortgage with some revolving room than a dormant safety net.

Valuation is usually light. Because an investment line caps at $500,000 and full appraisals begin only above that size, an investment HELOC generally runs on an automated valuation and commonly closes with no traditional appraisal. A higher CLTV may call for a secondary valuation, and you may request a full appraisal. If you are counting on post-rehab value, an automated valuation will not capture it, so ask for the appraisal.

Eligible property types include single-family homes, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered.

Borrower-level limits also apply: up to three lines per borrower, combined exposure of $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program, and no eligibility for borrowers with more than 15 financed properties. Bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year seasoning path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure or short sale.

Availability is narrower than the DSCR footprint. These lines are offered in Lendmire’s 16 full-service states, while its complete DSCR loans guide covers the 41-market investor lending side.

What About LLC-Owned Rentals?

An LLC cannot hold title on this product. The same goes for corporations, partnerships, and irrevocable, blind or land trusts. Only an individual borrower or an inter vivos revocable living trust can vest title.

This is the sharpest structural difference from a DSCR loan. If the rental already sits in an LLC, there are two practical paths:

• Change the vesting into your name or a revocable trust, which has its own cost and lender-notice implications to review first.
• Use a DSCR cash-out refinance instead, which can accommodate entity-titled properties, subject to lender program eligibility.

Retitling an existing mortgaged property can trigger lender questions, so that step deserves a conversation with your attorney and lender before you act.

HELOC or DSCR Cash-Out: Which Fits?

The answer depends on whether your income or the rent is the stronger underwriting story, and on how your property is titled.

A DSCR cash-out qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across most of the network it tops out around 75% LTV with about 6 months of seasoning as the common expectation, and most programs want a credit score near 660. Coverage of 1.00 is where select programs start, and a separate select-lender path goes below 1.00 with leverage and terms adjusted.

The HELOC fits an investor who owns the property personally, holds the equity cheaply behind a low first mortgage, and wants to avoid refinancing the first loan. The DSCR cash-out fits when the first mortgage is expensive to replace, the property sits in an LLC, or the file is stronger on rent than on personal income.

Note that DSCR math is rent against principal, interest, taxes and insurance only. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management and capex sit outside the ratio.

What Can Go Wrong?

Three risks deserve attention before you sign.

• Payment step-up. Pricing floats, and the payment changes when the 5-year interest-only draw ends and amortization begins. A line that cash-flows during the draw can look different in repayment.
• Second-lien exposure. A floating line stacked on a first mortgage reduces the cash flow cushion. Stress-test the rental at the repayment-period payment, not just the interest-only one.
• Borrowing against your home instead. Some investors tap their own residence when a rental line does not fit. Bankrate’s overview of HELOCs on investment property lists that option, but it moves the risk onto the home you live in.

Proceeds use matters for taxes too. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

Key Terms Defined

CLTV (combined loan-to-value): all liens on the property plus the new line, divided by the property’s value.

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

Expense factor: the share of business deposits an underwriter treats as operating costs, not income.

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

Qualifying income: the adjusted income figure an underwriter tests against your debts.
