Top Investment Property HELOC Providers for a Third Lien Position on a Rental

The Quick Read: A third-lien HELOC on a rental is a rare product, and which providers write one depends on the property, the lien stack, and the borrower’s equity. Lendmire is a mortgage broker, and the investment-property lines in its wholesale network sit in first or second position only. A third-position request therefore falls outside those lines and calls for a different structure.

• Lien position follows recording order, not loan type. A second HELOC on a property that already has one is a third lien.
• On the network’s investment-property lines, the ceiling is 70% combined loan-to-value (CLTV), the credit floor is 700, and the maximum line is $500,000. Each figure is subject to lender guidelines.
• Those lines require title in an individual’s name or a revocable living trust. An LLC cannot hold title.
• When the stack is already two deep, a DSCR cash-out refinance that replaces it with one first lien is one way to bring the file back into a single-lien structure.

What Does Third Lien Position Mean on a Rental?

A third lien is a loan recorded behind a first mortgage and one other junior lien. That junior lien is usually a HELOC, a home equity loan, or a subsidy lien. Position is set by recording order. Bills.com explains that a HELOC typically is a second lien when a first mortgage exists, and with no other mortgage on title it can be the first lien.

That matters because investors often say second HELOC when they mean a new line on a property that already carries one. In that case the new line is third. If the first mortgage is foreclosed, proceeds go to the senior lienholder first, and the junior lenders take what remains. A Massachusetts law firm notes the sale extinguishes the junior lien but the debt can survive, which is why third-position lenders price for risk or decline.

Why Do Most Lenders Stop at Second Position?

Most lenders stop at second position because the third lender is repaid last, from the thinnest slice of equity. On a rental that problem compounds. NerdWallet describes investment-property HELOCs as having a smaller lender pool and stricter requirements than lines on a primary home, and notes some lenders may require more than one appraisal.

One investor in a BiggerPockets thread says large banks do not take third position and points to a local bank or private money as the likelier route, while warning that even that stays difficult. The thread is an anecdote and is years old, so read it as color rather than a market survey. Third position on a rental stacks two narrowing pools on top of each other.

Who Writes This Kind of Loan?

No directory of third-lien providers is worth trusting, and the broker model doesn’t work that way. Lendmire works with a network of wholesale HELOC lenders and does not name, rank, or recommend any of them. The right program for a given file depends on property type, credit profile, leverage need, and documentation. This is the general shape of the market by lender category.

The network’s investment-property lines, as Lendmire places them, are standalone lines in first or second lien position. A file that needs third position falls outside that structure. The practical work is deciding whether the stack can be changed so the line fits, not finding someone who will accept a third lien.

How Do Lenders Run the CLTV Math With Two Existing Liens?

Lenders add up every recorded lien, divide by current value, and compare the result to the program’s CLTV cap. The CFPB’s HELOC booklet shows the arithmetic: value times the lender’s percentage, minus what is already owed. The booklet is written for consumer lines on a home, but the subtraction works the same way on a rental.

Here is a worked example in percentages of value. Say the first mortgage is 50% of value and an existing HELOC has a limit of 15%. Together they sit at 65%. Subtracting 65% from the network’s 70% CLTV ceiling on an investment property leaves a new line 5% of value to work with. Against a line of any useful size, that is thin room.

Two details change the picture:

• The full limit counts. Many lenders count the existing line’s full limit, not its drawn balance. A line with a zero balance can still use up CLTV room, so confirm the treatment with the lender.
• Hidden liens count too. Soft subsidy liens, judgments, and HOA liens can turn an apparent second into a third. A grant lien that surfaces in title can block a line.

For market context, NerdWallet reports that investment-property HELOCs generally call for at least 20% equity. The network figure is a 70% CLTV ceiling on an investment property, which means at least 30% equity after the new line.

What Do Investment-Property Lines Require in Lendmire’s Network?

These figures apply to investment-property lines placed through the wholesale network, each subject to lender guidelines and full file review. They are not a commitment to lend.

• Leverage: the ceiling is 70% CLTV on an investment property. A 700 and a 720 credit profile both reach it, so a higher score adds eligibility, not leverage.
• Credit: 700 is the floor on investment lines, with no tier beneath it.
• Line size: an investment line runs up to $500,000. Lines above that are for primary residences only.
• Structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing, and the pricing floats and does not convert to fixed.
• Debt-to-income: a 50% maximum, qualified on the interest-only payment at the maximum draw. Qualification is borrower-based, not rent-based.
• Valuation: because investment lines cap at $500,000, they ordinarily run on an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation, and a borrower may request a full appraisal.
• Property types: single-family, 2-4 units, PUDs, townhomes, and condominiums including non-warrantable. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
• Title: an individual or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
• Exposure: a borrower is limited to three lines, and anyone with more than 15 financed properties is not eligible.
• Availability: these lines are written in 16 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.

The vesting rule catches many investors. A rental already deeded to an LLC needs a change in title or a different product altogether. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.

Where the General Rule Breaks

Several edge cases change the answer.

The existing line is paid off. If the first mortgage and the current HELOC are both paid off, a new line can become the first lien. Bills.com notes a cash-out refinance can roll a HELOC balance into a new first mortgage and remove the second lien.

The first mortgage is refinanced later. With two junior liens behind it, each needs a payoff or a subordination agreement. The junior lender decides whether to subordinate, and it can refuse. A third lien multiplies those consent steps.

The line is frozen or reduced. A HELOC lender can generally freeze or reduce a line if value falls or the borrower’s finances worsen, according to the CFPB booklet above. A third-position line has the thinnest cushion, so it is the most exposed to a value drop. An investor planning to fund a purchase from the line should plan for that risk.

The property sits in an LLC. The network’s investment lines cannot be written against LLC-vested property. This is the sharpest difference from a DSCR loan, and it can eliminate the product before any math is run.

The investor wants to keep a low first mortgage. This is the main reason investors look at a junior line instead of a refinance. A third lien keeps that first mortgage in place at the cost of locking up equity and complicating any later refinance.

Note that the CFPB booklet describes consumer lines on a home. Lines on rentals are generally business-purpose credit, so do not assume every consumer protection in that booklet applies to a rental line.

When a DSCR Cash-Out Refinance Replaces the Stack

A DSCR cash-out refinance swaps the whole stack for one first lien. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, so it does not depend on anyone accepting third position. The mechanics sit in the complete DSCR loans guide.

Across the network, cash-out tops out around 75% LTV on a standard rental, with about 6 months of seasoning as the common expectation. On a short-term rental, cash-out is capped at 70%. Credit floors start around 620 in parts of the network, with most programs wanting about 660. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), so the cash-out route can reach well beyond the $500,000 investment line cap. Reserves vary by lender, leverage, and loan size, and commonly run around 6 months of PITIA.

A coverage ratio of 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, and capex sit outside it. Select lenders in the network also offer coverage below 1.00, with leverage and terms adjusted.

The trade-off is that a refinance replaces the existing first mortgage. An investor who wants to keep a low-rate first lien is the one who looks at a junior line, and that investor may want a second-position line rather than a third.

What to Ask a Provider Before Applying

Get these answers in writing before spending money on valuations or title work.

1. Does the program accept third position on a non-owner-occupied property?

2. How does it count the existing line, by limit or by balance?

3. Can title be held in a trust, or must it be an individual?

4. Is the line capped, and is a full appraisal required?

5. What happens to the line if the first mortgage is refinanced later?

A provider who cannot answer the lien-position question in the first conversation is one to set aside.
