The Quick Read: The best program for your situation is rarely a true third-lien line, because the investment-property lines Lendmire’s wholesale network places are written in first or second position only, so the practical path is usually to consolidate the stack, restructure it, or replace it.
- Investment-property lines in the network cap at 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a maximum line of $500,000.
- A new line must sit in first or second position, so a rental that already carries two liens usually needs a restructure first.
- The LLC-titled rental is the most common dealbreaker, because these lines require the individual borrower or a revocable living trust to hold title.
- A cash-out refinance on the property’s rent coverage is often the cleaner answer when the stack is already crowded.
Key Terms Defined
Lien position is the order in which claims get paid from a foreclosure sale, and it follows recording order, not product name.
Third lien is a new loan recorded behind a first mortgage and an existing second lien.
CLTV is every lien on the property added together, divided by the property’s value.
Junior lien is any lien that ranks behind another one and gets paid only after the senior claims are satisfied.
Subordination agreement is a signed, recorded document in which a junior lienholder agrees to stay behind a new senior loan.
Vesting is the legal way title is held, such as an individual, a trust, or an LLC.
DSCR is the debt service coverage ratio, which compares a rental’s income to its monthly obligation on the property.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
What Counts as a Third Lien on a Rental
A third lien is whatever records third. Name has nothing to do with it. Nolo’s lien priority explainer notes that junior lienholders collect only after every superior lien is paid in full, which is exactly why third position is hard to place.
Picture a rental with a purchase mortgage, a closed-end second mortgage taken for renovations, and now a request for a line on top. The new line is third. It gets paid last. If the sale proceeds fall short, it can get nothing.
Position can also shift without you choosing it. A line you meant as a second becomes a third if another lien records ahead of it. Some claims, like property tax liens, can also jump ahead of earlier mortgages, so a lender’s title search looks for more than mortgages.
That is the core reason lenders resist this structure. The third lender holds the thinnest cushion and the most exposure.
Is a Third-Lien Investment HELOC Actually Offered?
For the programs Lendmire brokers, no. A third-position line on a rental is not part of the network’s investment-property product. The line is a standalone loan in first or second position, and every file is reviewed individually by the lender.
That squares with the wider market. NerdWallet’s guide to HELOCs on investment property says these lines are not offered by every lender, carry strict requirements, and allow less borrowing than a line on a primary home. Add a third-position request and the pool narrows further.
So why do some pages say third liens exist and others say they are impossible? Both are partly true. A private or specialty lender may write a junior note behind two liens, usually at a cost and with terms that reflect the risk. A bank or wholesale program built for standardized investor lines usually will not. The honest answer depends on the lender type, not the property.
For investors who need a true third-position note, that is a private-lending conversation. It is outside the network’s investment-property lines.
How Underwriting Treats the Stack, Step by Step
Underwriting an investment-property line follows a fixed sequence. Knowing it tells you where a crowded stack fails.
1. Title search. The lender identifies every recorded lien, its order, and any judgment, tax, or association liens.
2. Valuation. Because an investment line is capped at $500,000, valuation ordinarily runs on an automated model with no traditional appraisal. A borrower may still request a full appraisal.
3. CLTV test. Value times the 70% investment ceiling, minus the first mortgage, minus the existing second, equals the room left.
4. Borrower qualification. These lines are qualified on the borrower, not the rent. The minimum credit score is 700, and debt-to-income tops out at 50%, measured on the interest-only payment calculated at the maximum draw.
5. Title and vesting review. The individual or a revocable living trust must hold title.
6. Recording. Existing-lien paperwork is handled, and the new line records in its position.
Step 3 is where most third-lien requests die. Step 5 is where most LLC-held rentals die.
A Worked CLTV Example
Run the numbers on a rental valued at 100 units, with percentages standing in for dollars. These are modeled assumptions, not market data.
| Scenario | First lien | Existing second | Room under 70% CLTV |
|---|---|---|---|
| Light stack | 45% of value | 10% of value | 15% of value |
| Typical stack | 55% of value | 12% of value | 3% of value |
| Crowded stack | 60% of value | 15% of value | — |
The light stack has room, but it would be a third lien, and the network writes first or second only. The typical stack leaves a sliver too small to matter on a $25,000 minimum line. The crowded stack is over the ceiling before you ask.
Now the restructure. Pay off the existing second with the new line, and the new line becomes the second. In the light-stack case, the borrower’s usable room becomes the full 25% of value left under the ceiling after the first lien. That is the mechanic behind the usual workaround: replace the junior lien rather than add to it.
Two cautions apply. Lenders commonly count the full limit of an existing line against CLTV, not just the drawn balance, so ask for that treatment up front. And if the existing second is a line with a prepayment or closure term, read it first.
Where the General Rule Breaks
Edge cases decide more of these files than the headline numbers do. Here are the ones that matter.
The rental sits in an LLC. Investment lines in the network require the individual borrower or a revocable living trust to hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. Federal consumer-credit rules separately exempt credit extended to a non-natural person such as an LLC, per eCFR’s text of 12 CFR 1026.3, but that exemption does not make an LLC-held property eligible for these lines. A rental already deeded to an LLC needs a vesting change or a different product, which usually means a DSCR cash-out.
The senior lien needs to consent. Refinancing a first mortgage while a junior lien exists usually requires the junior holder to sign a subordination agreement or be paid off. The junior holder is not obligated to agree. Read the senior loan documents before you plan around a stacked position.
Other liens complicate the picture. Tax, mechanic’s, and association liens can outrank or sit beside a new lien depending on state law. A clean title search matters more than a clean CLTV.
Freeze and reduction risk. Federal Reserve guidance on consumer HELOCs says a lender may freeze or reduce a line after a significant decline in property value, with written notice to the borrower. Those rules are written for consumer lines, and how they apply to a rental line is not settled. Treat the risk as real either way. A highly leveraged position is the first to feel it.
Property type. Single-family, two-to-four-unit, PUD, townhome, and condominium rentals (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Portfolio size and geography. A borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible. This HELOC program is available only in Lendmire’s 16 full-service states, narrower than its DSCR footprint.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.
Because investment lines are business-purpose credit, they are reviewed differently from a standard owner-occupied mortgage. That affects how the line is documented and disclosed. It does not change the equity math above.
What the Investment Line Looks Like When It Does Fit
Where the stack has room, the line itself is simple to describe.
| Feature | Investment-property line |
|---|---|
| Maximum CLTV | 70% (720+ and 700+ credit tiers both reach it) |
| Minimum credit | 700 |
| Line size | $25,000 to $500,000 maximum |
| Draw and repayment | 5-year interest-only draw, 25-year amortizing repayment |
| Drawn at closing | At least 75% of the line |
| Pricing | Floats through draw and repayment; never converts to fixed |
| Lien position | First or second |
Credit above 700 buys eligibility, not extra leverage, because both tiers top out at the same ceiling. The draw requirement matters too. If you need only a small slice, a line that requires most of it drawn at closing may not fit the purpose.
Floating pricing and the move from interest-only to amortizing payments are the real stress points. Payment behavior changes when the draw period ends, so model the repayment phase before you commit.
Alternatives Compared
If the stack is too crowded for a line, these are the structures that usually get considered. Each trades something away.
| Option | What it replaces | What it keeps | Fits when |
|---|---|---|---|
| Line in second position | Existing second | First mortgage | The second is small or restructurable |
| Cash-out refinance on rent coverage | The whole stack | Nothing; one new first lien | Rent covers the new payment and the stack is heavy |
| Line on a primary home | Nothing | Rental liens untouched | Primary has equity and you own the title individually |
| Private junior note | Nothing | All existing liens | Short-term need; cost is no issue |
A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It also allows LLC vesting, subject to program eligibility. On a standard rental, cash-out tops out around 75% LTV across most of the network, and a typical cash-out file expects about 6 months of seasoning. The tradeoff is that you give up your existing first mortgage, which may be the best feature of the stack. Investors holding a low-cost first often prefer the line. Investors with two liens and an LLC usually prefer the cash-out.
Lendmire’s complete DSCR loans guide covers how the coverage test works. For a rental with a first lien already in place, best investment property HELOC program on a rental without refinancing the first lien explains the second-position version of this structure.
Which Situation Are You In?
If your rental has a small second and the first lien is modest, consolidating into a new second-position line may work. That is the cleanest version of what you are trying to do.
If the property sits in an LLC, skip the line. A change of vesting or a DSCR cash-out is the realistic route.
If the combined balance is already near 70% of value, no line fits. A cash-out or a different source of equity is the honest answer.
If you hold substantial equity in a primary home, a line on that home can fund a rental without touching the rental’s liens. The tradeoff is that your own residence now secures the investment. Weigh that risk carefully.
And if you only need short-term money behind a stack, a private junior note exists. It is a different product with different costs, and it does not run through this network.
The “best” program here is the one that fits your title, your stack, and your reason for borrowing. A broker that shops multiple wholesale lenders can match the file to the right structure. A single bank cannot.
Frequently Asked Questions
Can I get a third-lien HELOC on a rental property?
Not through the investment-property lines in Lendmire’s network, which are written in first or second position. Third-position notes exist in the private-lending market, with terms that reflect the added risk. Most investors with a crowded stack end up replacing the existing second or doing a cash-out instead.
Why do lenders refuse third position?
Because the third lender gets paid last and is the likeliest to take a loss if the property sells for less than the combined debt. A junior holder also cannot stop a senior foreclosure from wiping out its claim. Thin equity, plus a variable-payment line, compounds that exposure.
Can an LLC hold title to the property?
Not for these lines. Title must be held by the individual borrower or a revocable living trust, so an LLC-owned rental needs a vesting change or a different product. A DSCR cash-out is the usual alternative, subject to lender program eligibility.
What if my existing second is itself a HELOC?
Underwriters commonly count the full limit of that line, not only the balance drawn. If you want the new line in second position, the existing line generally has to be paid off and closed. Check its closure terms first.
How much can I borrow against a rental?
Up to 70% combined loan-to-value on an investment property, with a maximum line of $500,000 and a minimum 700 credit score, subject to lender guidelines. Whatever the first lien and any second lien already consume comes off the top.
