The Quick Read: Everyone on the deed signs the lien, but only the people who qualify sign the note. One co-owner may be able to borrow alone if that person’s credit and debts clear the test, and the other owner signs only to pledge their share of the property. On an investment property, the network’s ceiling is 70% combined loan-to-value (CLTV), and the title must sit with an individual or a revocable trust.
- The deed decides who signs the lien. Credit and income decide who must be on the note.
- A non-borrowing co-owner takes on no repayment duty, but their equity backs the debt.
- Investment lines in the network need a 700 credit score and a maximum line of $500,000.
- LLC-titled rentals are not eligible for this product.
- If a co-owner will not sign, the file stops, and other paths exist. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Two friends buy a duplex. Two siblings inherit a fourplex. An unmarried couple owns a rental together. Each wants to pull equity out, and each runs into the same question: who has to be on this loan? This guide walks through how underwriting treats a shared deed, step by step. It also covers the variations, the edge cases, and the decisions that follow. Lendmire is a broker, so every figure below is subject to lender guidelines and full file review, and none of it is a commitment to lend.
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.
Key Terms Defined
Note. The promise to repay. Whoever signs the note is a borrower, and their credit, income, and debts get underwritten.
Lien (security instrument). The document that pledges the property as collateral. It is a mortgage or a deed of trust, depending on the state.
Vesting. How title is held, such as an individual, joint owners, or a revocable trust.
CLTV (combined loan-to-value). All loans against the property, added together, divided by its value.
HELOC. A home equity line of credit. You draw against it as needed, and it has a draw period followed by a repayment period, as the CFPB describes.
Non-borrowing owner. Someone on the deed who signs the lien but stays off the note.
Who Signs What? The Note Versus the Lien
Signing the note and signing the lien are two different acts, and the difference matters for shared deeds.
The note creates personal debt. The lien pledges the property. A lender can only take security on what the signer actually owns. A co-owner can generally pledge only their own undivided share. If a lender held a lien on just one fractional share and foreclosed, the buyer would step in as a co-owner with the right to ask a court to split up the property. That is weak collateral, so lenders want every titleholder to sign the lien.
The federal rule behind this is Regulation B, which implements the Equal Credit Opportunity Act. It says a lender generally cannot demand a cosigner when you qualify alone. It also lets the lender require signatures on whatever documents state law makes necessary to pledge the collateral. The eCFR text of 12 CFR 1002.7 covers both points, and the rule says “other person,” not just spouses. An unmarried co-owner is treated the same way a spouse on title would be.
Put plainly: the lender cannot force your partner onto the loan if you qualify alone. The lender can require your partner to sign the lien, because without that signature the property cannot be pledged in full.
How Underwriting Treats a Shared Deed, Step by Step
Here is the sequence a file follows.
1. The vesting deed comes first. It shows who is on title, in what form, and whether the property sits in an individual’s name, a revocable trust, or an LLC. Everything else depends on this page.
2. The group decides who borrows. Whoever is on the note gets their credit, income, and debts reviewed. A non-borrowing owner stays out of the credit file.
3. Everyone on title signs the lien. This applies whether or not they borrow. It follows from the secured-credit exception in 12 CFR 1002.7(d)(4).
4. Valuation runs. An investment line in the network tops out at $500,000, and full appraisals begin only above that figure. So an investment line is structurally in the automated-valuation lane and commonly closes with no traditional appraisal. A borrower can still request a full appraisal.
5. The personal-credit tests apply. Unlike a DSCR loan, a HELOC is underwritten on the borrower’s credit and debt-to-income ratio (DTI), not on the rent. DTI is capped at 50%. Qualification uses the interest-only payment calculated on the maximum draw.
6. Closing and draws follow. Both owners sign the lien and the closing documents. Later draws generally do not need the lien-only signer involved, and the minimum subsequent draw is $1,000.
The Scenarios: One Borrower, Two Borrowers, or a Stalled File
| Situation | On the note | Signs the lien | Whose credit counts |
|---|---|---|---|
| One owner borrows alone | That owner | Both owners | Borrower only |
| Both owners borrow | Both | Both | Both, blended |
| One owner refuses to sign | n/a | Can’t pledge whole property | File stops |
One owner borrows alone. This keeps the other owner’s credit and debts out of the file. It also protects the borrower if the partner has thin credit. But the partner still signs the lien, so their equity is exposed if the borrower defaults.
Both owners borrow. Both credit profiles and both sets of debts go into the file. A strong borrower can be dragged down by a partner with heavy debt. Run the numbers both ways before choosing.
One owner will not sign. Then the whole-property lien cannot close. The options are a buyout, a retitle, borrowing against a different property you own alone, or a different product altogether. We cover those below.
What the Network Requires on an Investment Line
The wholesale network behind this product treats investment lines more tightly than lines on a primary home. The figures below apply to investment properties only and are typical guideline ranges, subject to lender review.
- Leverage: 70% CLTV is the ceiling on an investment property. Credit above the floor buys eligibility, not extra leverage.
- Credit: 700 is a hard floor, with no tier beneath it. Scores of 720 and 700 sit in the same tier.
- Line size: $25,000 to $500,000 on an investment property. Larger lines are limited to primary residences.
- Structure: a standalone line in first or second lien position, with a 5-year interest-only draw and a 25-year repayment period. At least 75% of the line is drawn at closing.
- Property types: single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.
- Exposure: a borrower can hold up to three lines, and an owner of more than 15 financed properties is not eligible.
- Derogatory history: a bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path for foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
One more point matters for shared deeds. Business bank accounts need a 680 minimum for deposit analysis, but an investment line already floors at 700. So bank-statement income is never the binding limit here.
Availability is narrower than the DSCR footprint. This product is offered in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. Some of those states add their own wrinkles, such as shorter repayment periods in Tennessee or listing-related ineligibility in a handful of states. Check your state before building a plan.
Title Type Changes the Picture
How you hold title shapes both the lien and your options.
Tenants in common. Each owner holds a separate share and can pledge it independently. For a lien that covers the whole property, both still sign.
Joint tenants with survivorship. The owners hold equal undivided interests with a right of survivorship. A conveyance or lien can sever that joint tenancy under some states’ laws. Have an attorney review this before signing. The principle that one co-owner can encumber only their own interest is stated in Illinois Legal Aid’s overview of shared property ownership, though state rules differ.
Revocable trust. A trust holding title is eligible, as long as it is an inter vivos revocable living trust. Irrevocable, blind, and land trusts cannot hold title.
LLC. Not eligible. This is the sharpest structural difference from a DSCR loan. Many investors hold rentals in an LLC, and subject to program terms, a DSCR loan can often lend to that entity. A HELOC in this network cannot. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead. Deeding property out of an LLC has legal, insurance, and due-on-sale consequences, so talk to an attorney before you move title.
Where the General Rule Breaks
Several situations bend the basic pattern.
A partner who is not on title wants to borrow. Most HELOC lenders require every borrower to own the property. Adding that person to title first has ownership and gift consequences. It is a legal decision, not just a paperwork step.
A cosigner who is not an owner. This depends on the lender. A lender may accept one but is not required to. Regulation B also limits when a lender can demand one, which is only when that person’s liability is needed to meet its creditworthiness standards.
A spouse off title. This is a different case than unmarried co-owners. Community-property and homestead states can require a joinder, which is a spouse’s signature on the lien.
An existing first mortgage. The network’s line can sit in first or second lien position. If you keep a first mortgage, the line sits behind it, and the CLTV counts both balances. The first mortgage’s borrower list does not change who signs the new lien.
Texas. The primary-residence rules there, including the waiting period and one-lien-at-a-time limit, bind homesteads only. A Texas investment property is eligible as a non-homestead transaction.
Properties listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
Market-wide caution. Some bank HELOC programs outside this network do not accept rental collateral at all. Confirm any product is a true non-owner-occupied investment line before you apply.
What Happens If Your Co-Owner Won’t Sign?
The file stops. You cannot pledge a partner’s share without their signature. Your realistic paths:
- Buy them out. You become the sole owner, and the whole file simplifies.
- Retitle. If the partner is willing to transfer, title can change, though this carries legal and tax consequences.
- Borrow against a different property that you own alone.
- Use a different product. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Still, it needs the co-owner’s signature when they are on title, so it only helps if the objection was about credit and not about pledging their share.
Co-owners who disagree about risk should talk about it before the application, not during it.
HELOC or DSCR Cash-Out on a Shared Rental?
The two products answer different questions. A HELOC looks at your personal credit and debts. A DSCR cash-out looks at whether the rent covers the property’s debt service.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Underwritten on | Personal credit and DTI | Property rent vs. debt service |
| Title allowed | Individual or revocable trust | LLCs often allowed, per program terms |
| Structure | Revolving line, floating | Term loan, 30-year fixed spine |
| Co-owner on title | Signs the lien | Signs the loan documents |
Cash-out on a standard rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. That is a different animal from the investment HELOC’s 70% CLTV cap. Coverage matters on the DSCR side: 1.00 is where select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, and management sit outside the calculation. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
A line also suits some strategies better. Investors who want a revolving source for down payments and rehab may prefer personal-credit financing, while someone scaling a portfolio may prefer rent-based loans. The complete DSCR loans guide walks through that comparison.
The Pledge Is Real: Protect the Signer
A non-borrowing owner should understand one thing: signing the lien puts their equity at risk. They owe nothing on the note, but if the borrower defaults, the lender’s claim reaches the property, including their share.
Two co-owners who borrow against a shared rental should put the following in writing before closing:
- Who may draw, and how much
- Who repays, and from what source
- How rent is split
- What happens if one owner wants to sell or exit
Without that agreement, the signer’s equity backs a debt they do not control. For more on qualifying as an owner on the deed, see Lendmire’s guide to qualifying for an investment property HELOC as a co-owner.
Also remember partition risk. If a lender foreclosed on one owner’s interest alone, a buyer could become a co-owner and force a sale. This is the very problem the all-owners-sign rule prevents.
A Pre-Application Checklist
- Pull the vesting deed and confirm how title is held.
- Confirm title is an individual or revocable trust, not an LLC.
- Check the credit score against the 700 floor for investment lines.
- List all debts for each potential borrower to estimate DTI.
- Confirm the property is an eligible type and is not recently listed for sale.
- Decide whether one owner borrows or both.
- Get the other owner’s agreement to sign the lien.
- Talk to a title company or attorney about vesting and survivorship.
State law on whether one co-owner can encumber the whole property varies, so title counsel is worth the fee.
Frequently Asked Questions
Can unmarried co-owners get an investment property HELOC together?
Yes, if both are on title and the property is held by individuals or a revocable trust. Both can borrow, in which case both credit profiles count, or one can borrow while the other signs only the lien. Either way, the property must meet network eligibility, and every figure is subject to lender guidelines.
Does everyone on the deed have to sign?
Yes, everyone on title generally signs the lien so the whole property can be pledged. Signing the lien does not make someone a borrower. Their share is pledged, but they are not personally on the note.
Can one co-owner borrow alone, and is the other personally liable?
One owner can borrow alone if they qualify on their own credit and DTI. The other owner has no repayment duty under the note. Still, their equity is exposed if the borrower defaults, so a written agreement on draws and repayment is wise.
Can my partner be a borrower if they aren’t on the deed?
Generally not. Adding your partner to title first has ownership and gift implications, so get legal advice before retitling.
What if the owners split up?
The lien stays on the property. If the line is open, both owners remain exposed until it is paid off, refinanced, or the property is sold. A written co-owner agreement should address who pays, who draws, and who keeps the property.
