How Much Can You Borrow on an Investment Property HELOC for Sellers Who Still Owe?

The Quick Read: On an investment property, the most you can borrow is the property value times a 70% combined loan-to-value ceiling, minus your existing mortgage and any other liens, then capped at a $500,000 line. Every dollar you still owe on the first mortgage comes straight out of the room available.

• The ceiling on an investment property line is 70% CLTV, and a score of 700 is the floor.
• The full credit limit counts toward CLTV, not just the amount you draw.
• A line tops out at $500,000 on an investment property, with a minimum line of $25,000.
• Title must sit with you personally or in a revocable living trust, so an LLC cannot hold it.
• If you sell, the line is generally repaid in full from the sale proceeds.

For a seller who still owes a large balance, the answer can be small. A line you must repay at closing is bridge money at best, not permanent capital.

How Is the Maximum Line Calculated?

Your maximum line is value times the combined ceiling, minus what you already owe. Combined loan-to-value (CLTV) adds the first mortgage and the new line together, then divides by the property’s value. Equity is the property’s value minus what you owe on the mortgage, as the CFPB’s HELOC brochure puts it. A line lets you borrow a percentage of that equity.

Here are the steps in order:

1. Establish the value. Investment lines at this size usually run on an automated valuation, and you can request a full appraisal. 2. Multiply value by 70%. 3. Subtract the first mortgage balance and any other liens. 4. Apply the program limits: $25,000 minimum, $500,000 maximum. 5. Confirm credit and title eligibility.

Remember that the lender counts the whole credit limit toward CLTV. Draw only half of a line, and the unused half still uses up your room.

What Does the Room Look Like at Different Balances?

The table shows how a first mortgage balance, expressed as a share of value, shrinks the line. It uses percentages of value only, and the dollar line is capped at $500,000 either way.

Run the math on a rental valued at a round number, say $400,000. Seventy percent of value is the ceiling. With a first mortgage at 45% of value, 25 points of value remain as room. Your own figures will differ, and an illustrative calculator can help you test a few balances. It is an estimate, not a quote.

Why Do Sellers Who Still Owe Hit a Wall?

A seller with a large mortgage balance has little room under a 70% ceiling. A rental bought at 75% LTV and not yet paid down sits above the ceiling on day one. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

NerdWallet notes that investment property HELOCs are not offered by all lenders and carry strict requirements. It also says they allow less borrowing than lines on a primary home. That fits what a broker sees across a wholesale network: the supply is thin, and ceilings sit well below the owner-occupied tiers.

On this network, an investment line is held to 70% CLTV, and a cash-out refinance on a standard rental tops out around 75% LTV. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

What Happens to the Line When You Sell?

The line is generally repaid in full when you sell. The CFPB brochure says that if you sell your home, you are generally required to pay off the line immediately. In practice, the title company orders a payoff statement and pays the balance from your sale proceeds. A lien release follows.

Three points matter for sellers:

• The line cannot move. It is tied to that property, so it cannot follow you to the next one.
• Order of payment. The line is usually a second lien, so it gets paid after the first mortgage.
• Net proceeds shrink. Whatever you drew, plus the first mortgage and closing costs, comes out of the price. If the total exceeds the sale price, you bring cash to the table.

Listed properties are a separate problem. Ask the specific lender before you plan around one.

Does Opening a Line Before a Sale Make Sense?

Usually not, unless you need bridge cash for something time-sensitive. You pay to set up a line, and the proceeds from the sale repay it.

Consider an owner planning to sell within a few months who wants a down payment ready for the next rental. The line would be repaid from the sale, so the net benefit is only the timing. Because most of the line must be drawn at closing, the owner would be carrying a large balance from day one.

This one is a genuine toss-up for some owners. Bridge liquidity can matter when a purchase contract has a hard deadline. For most sellers, waiting for proceeds avoids the cost and the extra lien.

What Does an Investment Line Require?

Across the wholesale network, the investment-property line looks like this:

• CLTV ceiling: 70% on an investment property, at 700 or higher. A 720 score does not buy more leverage; credit above 700 buys eligibility, not extra room.
• Line size: $25,000 to $500,000 on an investment property.
• Lien position: a standalone line in first or second position.
• Structure: a 5-year interest-only draw followed by a 25-year repayment, with pricing that floats and never converts to fixed.
• Draw at closing: at least 75% of the line.
• DTI: 50% maximum, qualified on the interest-only payment at the maximum draw.
• Property types: single-family, 2-4 units, PUD, townhome and condominium. Manufactured homes, co-ops, condotels, log homes and commercial or mixed-use properties are not eligible.
• Exposure: up to three lines per borrower, and owners with more than 15 financed properties are not eligible.

Availability is narrower than a DSCR footprint. These lines are offered in Lendmire’s 16 full-service states, and every figure here is subject to lender guidelines and full file review.

How Does Title Affect Eligibility?

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

If your rental already sits in an LLC, you have two options: change the vesting, or use a DSCR cash-out refinance instead, subject to lender program eligibility. Move title only after checking with your lender, insurer and attorney, since a deed change can have side effects.

What Are the Alternatives?

A cash-out refinance on a standard rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. It must also pay off or subordinate any junior lien. For the full picture, see the complete DSCR loans guide. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

An investment property HELOC works differently. It is qualified on your personal income and debts, with a 50% maximum DTI, rather than on rent.

One caution on DSCR math: clearing the coverage test does not mean positive cash flow. Repairs, vacancy, management, utilities and capex sit outside the calculation.

Key Terms Defined

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

Equity: The property’s value minus what you owe on it.

Second lien: A loan recorded behind the first mortgage, paid second at a sale.

Draw period: The stretch when you can borrow from the line, paying interest only.

Repayment period: The stretch after the draw ends, when principal and interest are both due.

Payoff statement: The lender’s document showing the exact balance owed to release the lien at closing.

Why Might You Be Declined?

Check these before applying:

• A credit score under 700.
• A first mortgage that already takes you to 70% CLTV or beyond.
• Title held in an LLC, corporation or irrevocable trust.
• A property type outside the program, such as a manufactured home.
• DTI above 50%, or above 45% for lower credit tiers.
• A property currently listed, or recently listed, in a state that bars those files.
• More than 15 financed properties, or three lines already open.
