The Quick Read: You can usually borrow on your own, but every titled owner typically has to sign the lien that secures the line, whether or not that owner is a borrower. Credit, income, and debt decide who borrows. Title decides who signs. The two lists do not have to match, and the lender looks at each one separately.
- Borrowing and signing are separate jobs. A co-owner who only signs the lien is not a borrower.
- A lien generally attaches only to the interest of the owner who signed it, so lenders want every owner on the paperwork.
- If a co-owner refuses, the line generally cannot close on the shared property.
- On an investment property, the Lendmire network tops out at 70% CLTV, with a 700 minimum credit score and a $500,000 maximum line.
- The network’s HELOC programs exist in Lendmire’s 16 full-service states, which is narrower than its DSCR footprint.
Say you and a sibling inherited a duplex and both names sit on the deed. You want to pull equity out. Your sibling wants nothing to do with a loan. That setup is more workable than most people expect, and it is also where most of these files stall. This article walks through who signs what, how underwriting treats each owner, the structures that exist, and where the general rule breaks.
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 Does Being “On the Deed” Actually Mean for a HELOC?
Being on the deed makes you an owner of the collateral. A home equity line of credit (HELOC) is a revolving credit line secured by a lien on the property. A lien is the lender’s legal claim on the property if the debt goes unpaid. Because the lien is placed on the property, anyone who holds title has a say in whether it can be placed.
That gives you two separate questions. Who qualifies for the debt? And who has to sign to let the lender take the property as security? Different people can answer each one.
Borrower vs. Titled Owner: Who Does What
The borrower signs the note, which is the promise to repay. The titled owner signs the security instrument, which is a mortgage or deed of trust that creates the lien. A co-owner who signs only the lien is not personally liable for the debt. The risk to that person is the property itself.
| Question | Borrower | Non-borrowing titled owner |
|---|---|---|
| Signs the note? | Yes | Generally no |
| Signs the lien? | Yes | Yes |
| Credit and income reviewed? | Yes | Generally no |
| Personally liable? | Yes | Generally no |
| Property at risk if unpaid? | Yes | Yes |
That last row is the one co-owners underestimate. If the borrower stops paying, the lender can foreclose on the property, and a non-borrowing owner’s equity is in that property. Texas A&M’s Real Estate Research Center notes that foreclosure is the remedy where a home equity loan is nonrecourse, meaning the lender looks to the property rather than the person.
Why Lenders Want Every Owner to Sign
A lender wants a lien on the whole property. A lien from one owner generally reaches only that owner’s share. With tenants in common, that would leave the lender holding a claim on a fractional interest it cannot easily sell. Other forms of co-ownership limit the lender’s rights even more.
So the practical rule is simple. Every titled owner signs the lien. No national rule says this in so many words. It is the result of state property law and lender policy, which is why the right word here is “generally.”
There is also a federal rule that works in your favor. A lender generally cannot demand that someone who is not an applicant sign the credit instrument if the applicant qualifies alone. The same rule lets the lender require signatures needed to make the collateral reachable. Put plainly, a lender cannot make your co-owner a borrower, but it can require your co-owner to sign the lien.
How Underwriting Treats Each Owner, Step by Step
Here is the sequence on a typical file through a wholesale network of lenders.
1. Title review. The lender or title company pulls the recorded deed. It identifies each owner and the form of ownership: joint tenancy, tenancy in common, tenancy by the entirety, trust, or other. The name and vesting on your application must match the recorded deed. A deed that was signed but never recorded does not change title in a lender’s eyes.
2. Role assignment. Credit, income, and debt decide who the borrowers are. Title decides who signs the lien.
3. Borrower underwriting. Only applicants are reviewed. A co-owner who is not on the application is generally not pulled for credit. If the lone applicant does not qualify, adding the co-owner as a co-borrower is the usual fix.
4. Property review. The lender values the property, checks existing liens, and calculates combined loan-to-value (CLTV). CLTV is the total of all loans against the property divided by its value. The CFPB’s HELOC booklet describes the standard sizing idea: a percentage of appraised value, minus what you still owe on the first mortgage. That is an older edition, so treat it as the concept, not current numbers.
5. Closing documents. The borrower signs the note. Every titled owner signs the lien. A non-borrowing owner may also sign an acknowledgment.
A word on valuation. On lines of $500,000 or less, the network programs ordinarily run an automated valuation without a traditional appraisal. Any line above $500,000 requires a full appraisal, and you can ask for one in any case.
What the Network Programs Look Like on an Investment Property
Many people assume a rental HELOC works like a primary-residence line with a slightly lower limit. It does not. NerdWallet reports that investment-property HELOCs are possible but come with fewer lenders and less borrowing power than lines on a primary home, because lenders treat rentals as higher risk.
Here is how the Lendmire network handles it. Lendmire is a broker. It places files with select wholesale partners and is never the lender.
- Leverage. On an investment property, the ceiling is 70% CLTV.
- Credit. The minimum score on an investment line is 700, and the 70% tier applies at 700 and above.
- Line size. The maximum on an investment property is $500,000. Lines above that are for primary residences only.
- Structure. Investment lines run 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 never converts to fixed.
- Debt-to-income. The maximum is 50% overall, and the lender reviews your file on the interest-only payment calculated on the maximum draw.
Market surveys describe much higher figures for equity lines in general. Those describe the broader market, not this network. On an investment property here, 70% CLTV is the ceiling.
For comparison, primary residences and second homes sit in different tiers. A second home reaches 90% CLTV only at a 720 score or better, with a 640 minimum score. A primary residence reaches 90% CLTV only at 720 or better as well, with a 600 minimum. Do not read those tiers as available on a rental.
Title and Vesting: The Sharpest Catch
The network requires that title be held by an individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. If your rental already sits in an LLC, you need a vesting change or a different product. A DSCR cash-out refinance, subject to program terms, is the usual alternative, and Lendmire’s complete DSCR loans guide explains how that structure is reviewed on property rental income instead.
This matters for co-owners because many partners hold a rental through an LLC to share ownership cleanly. If that is your setup, a HELOC on that property is generally off the table.
How Your Deed Type Changes the Picture
Each form of co-ownership has a different legal effect, and the effect varies by state.
| Deed type | How it works | HELOC effect |
|---|---|---|
| Joint tenancy | Equal shares, survivorship | All owners generally sign the lien |
| Tenants in common | Separate shares, no survivorship | A single owner’s lien reaches only that share |
| Tenancy by the entirety | Married couples only, in some states | Lender rights heavily limited without both |
| Trust or LLC | Signer acts per the governing documents | Trusts may work; LLCs generally cannot hold title |
Wikipedia’s overview of concurrent estates covers these forms in more detail. For your file, the point is simple. The lender will want every owner’s signature on the lien regardless of deed type, because partial liens are hard to sell on default.
Scenarios: Who Signs What
| Situation | Who borrows | Who signs the lien |
|---|---|---|
| Two siblings on the deed, one wants the line | The one applicant, if they qualify alone | Both |
| Two siblings on the deed, neither qualifies alone | Both as co-borrowers | Both |
| Married couple, both on the deed | One or both | Both |
| Married, only one on the deed | The titled spouse | Depends on state and lender policy |
| Business partners on the deed | One or both | Both |
In the second row, adding the co-owner as a co-borrower is how a file that misses on one person’s credit or income gets fixed. Both owners’ credit and debts then count.
One note on a cosigner who is not an owner. Lenders generally prefer that anyone liable on the line also be on title, so a non-owner cosigner is harder to place.
A Worked Example: Two Siblings, One Borrower
Picture two siblings who co-own a single-family rental, both on the recorded deed as tenants in common. Sibling A has a 700-plus score and wants a line. Sibling B does not want to borrow.
The file runs like this. Title confirms both names. Sibling A applies alone. The lender reviews Sibling A’s credit, income, and debts, and the combined loan-to-value against the 70% investment-property ceiling. If Sibling A qualifies, Sibling A signs the note and the lien. Sibling B signs the lien only, and Sibling B is not pulled for credit.
What Sibling B gives up is the right to keep the property free of that lien. The property now secures Sibling A’s debt, and if Sibling A stops paying, Sibling B’s equity is exposed. That is why the conversation before the application matters more than the paperwork.
What If Your Co-Owner Won’t Sign?
A lender cannot force a co-owner to sign. If the answer is no, the line generally cannot close on the shared property. You have four practical options.
- Buy the co-owner out. You become the sole owner and can borrow alone. This is the cleanest path and often the most expensive up front.
- Restructure title. A partition or title change can separate the interests, though it takes legal work and may trigger issues with the existing first-lien lender.
- Use a different product. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and may work when no one wants a personal line.
- Power of attorney. Some lenders accept one, but it depends on the lender and the state, and some states require the signing at the closing office. Treat it as a question to ask, not a plan.
If you are weighing a refinance against a line, Lendmire’s piece Can a W-2 Homeowner Open a HELOC Without a Co-Owner Signing? covers the sole-signer side of the same question.
Where the General Rule Breaks
Homestead states. Texas is the strictest example. The state constitution requires a home equity lien to be created with the consent of each owner and the owner’s spouse, per Texas A&M’s Real Estate Research Center. A married spouse who is not on title may still have to sign. These rules protect a homestead, which means they are about owner-occupied property, not rentals. Do not carry Texas-style spousal consent to every state.
Community-property states. A spouse who is not on title may still be asked to sign. Policies vary by state and lender, so confirm with the lender before you assume either way.
Common-law states. If the deed is in one name only, the spouse is usually not required to sign. That varies by state and lender policy.
Divorce and title changes. Taking your name off the deed does not by itself take you off the debt. The deed moves ownership and the note moves the debt. Adding someone to the deed, on the other hand, makes that person a lien signer. A transfer to a spouse or child on a rental can also raise due-on-sale issues with the existing first-lien lender, so get written consent from that lender first.
Owner-occupied rescission. On a primary home, a titled owner who is not on the note can have a right to cancel the loan within a short window. That right does not apply to an investment property, which is one more reason rental lines run on different rules.
What This Means for an Investor
A HELOC is a narrow tool on a rental. The leverage is lower than on a home you live in, and the lender pool is smaller. The structure also matters. A 5-year interest-only draw followed by a 25-year repayment means your payment steps up when the draw ends, and the pricing floats the whole way.
A second lien also affects what you can do next. If you later want a cash-out refinance on the same property, the line generally has to be paid off or dealt with, and the same all-owners logic applies. That is a practical inference from how liens work, not a program rule. A DSCR loan, by contrast, qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and a co-owner’s personal finances matter less. Clearing the DSCR test does not mean the property cash flows once repairs, vacancy, and management are counted.
Exposure caps matter for active investors. A borrower is limited to three lines on these programs, and a borrower with more than 15 financed properties is not eligible.
Before You Apply: The Co-Owner Conversation
Settle these items with your co-owner first.
- Purpose. What the money is for, and who decides when to draw.
- Payments. Who makes them, and what happens if that person misses one.
- Exposure. Both owners should understand that the property secures the line.
- Exit. What happens if one owner wants to sell or buy out the other.
- Documents. Deed type, ownership percentages, existing liens, and who must attend closing.
Tax treatment varies; consult a qualified professional before relying on any deduction.
Key Terms Defined
HELOC: a revolving credit line secured by a lien on property, with a draw period followed by repayment.
Lien: the lender’s legal claim on the property if the debt is not repaid.
Note: the signed promise to repay, which creates personal liability.

Tenants in common: a form of co-ownership with separate shares and no survivorship.
Vesting: how title is held, as shown on the recorded deed.
Frequently Asked Questions
Can one co-owner get a HELOC without the other co-owner borrowing?
Usually, yes, if the applicant qualifies alone. The other titled owner generally still has to sign the lien, but does not have to sign the note or be reviewed for credit. A lender cannot require your co-owner to become a borrower just because they own the property.
Does signing the lien make my co-owner liable for the debt?
Generally no. A titled owner who signs only the security instrument is granting a claim on the property, not promising to repay. The exposure is the property itself, because the lender can foreclose if the borrower defaults.
What credit score do I need on an investment property?
The network’s investment-property lines start at 700, with the 70% CLTV ceiling available at 700 and above. Maximum line size is $500,000. All figures are subject to lender guidelines and full file review.
Can my LLC-owned rental qualify for one of these lines?
Generally no. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance may fit, subject to program terms.
What if the co-owner is a spouse who isn’t on the deed?
It depends on the state and the lender. In homestead states like Texas, a non-titled spouse may still be required to sign on an owner-occupied home. In many common-law states, a spouse who is not on title is usually not required to sign. Ask the lender before you apply.
