The Quick Read: When two names are on a deed, both names usually go on the lien, but only the people who apply for the line owe the debt. One partner can often borrow alone while the other signs only the mortgage that pledges the shared home. Marriage does not change that split. It only widens the ways of holding title that are open to you.
- The deed decides who signs the lien. The application decides who owes the debt.
- A partner who signs only the lien risks the shared property but is not personally on the hook for repayment, because the debt belongs to whoever signs the note.
- A partner who applies as a co-borrower can generally be pulled for the whole balance, not half.
- On an investment property, network equity lines top out at 70% combined loan-to-value (CLTV). Primary residences and second homes reach higher, with the top tier reserved for strong credit.
- If a rental is deeded to an LLC, a home equity line is off the table, and a DSCR cash-out refinance is the usual route.
Key Terms Defined
HELOC: A home equity line of credit, a revolving line you draw on, secured by a lien on property you already own.
Note: The signed promise to repay. Whoever signs the note owes the debt.
Lien (mortgage or deed of trust): The document that pledges the property as collateral. Whoever owns the property must generally sign it for the lender to reach the whole asset.
Co-borrower: A person who applies jointly. Their income, credit, and assets count, and they share liability for the debt.
Lien-only signer: A titled owner who signs the lien but not the note.
CLTV: Combined loan-to-value, meaning all loans against the property added together, divided by its value.
DSCR: Debt service coverage ratio, which compares a rental’s income to its full monthly obligation. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
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 the Deed Control, and What Does the Application Control?
The deed controls the collateral. The application controls the debt. Those are two separate lists, and unmarried couples often assume they must match.
Say the deed shows you and your partner as owners. A lender that wants a first-priority or second-priority lien on the whole property needs every record owner to sign the mortgage. Otherwise it cannot reach a non-signing owner’s share if the line goes bad.
The application list works differently. If you qualify alone for the line you want, you can usually apply alone. Your partner then appears on the lien but not on the note.
Lendmire brokers equity lines through select wholesale partners, and the file starts with a title pull. Who owns the property and how title is vested comes before income, credit, or leverage.
How Underwriting Treats Two Names on One Deed
The process runs in a fixed order, and each step changes what the next one asks for.
1. Title review. The lender identifies every owner on the recorded deed and how they hold title.
2. Application choice. One partner applies alone, or both apply as joint applicants. Joint applicants are underwritten together, with their income and assets combined.
3. Underwriting. Only the people on the note are underwritten as borrowers. A lien-only signer is not underwritten for repayment.
4. Credit and debt-to-income review. Network programs cap debt-to-income at 50%, and at 45% for profiles from 600 to 679. The line is qualified on the interest-only payment calculated on the maximum draw. Credit minimums depend on occupancy and program, so the score that counts is the one tied to the property type being financed.
5. Signing. The note carries the borrowers’ signatures. The mortgage or deed of trust carries every titled owner’s.
6. Lien position check. The line can sit in first or second position. If a first mortgage already exists, it must allow a second lien, and combined leverage has to fit the cap.
A weaker credit profile on a co-borrower can drag down a joint application. That is the main reason a stronger partner often applies alone and the other signs only the lien.
Who Signs What: A Scenario Matrix
| Scenario | Signs the note | Signs the lien | Who is exposed |
|---|---|---|---|
| Both on deed, both apply | Both | Both | Both, for the full debt |
| Both on deed, one applies | One | Both | Borrower owes; other risks the property |
| Only one on deed | Titled owner | Titled owner | Titled owner only |
| Property held by an LLC | Not eligible for an equity line | Not applicable | Re-title or use DSCR |
The second row is the one unmarried couples ask about most. The non-borrowing owner takes no repayment duty. However, that partner’s share of the house still stands behind the loan.
Joint Tenants vs. Tenants in Common
How you hold title changes what each of you can pledge, which is why lenders ask for the vesting before anything else.
| Factor | Joint tenancy | Tenancy in common |
|---|---|---|
| Ownership | One equal, undivided interest | Separate shares, equal or not |
| On death | Survivor takes the whole | Share passes by estate plan |
| Lender wants | Every joint tenant on the lien | Every owner, if it wants the whole property |
In many states, a tenant in common can mortgage only their own share. That sounds convenient, but a lien on a fractional interest is hard to place, because a lender wants collateral it can actually sell. A lender seeking a lien on the entire house will want every owner to sign.
Tenancy by the entirety is the form most people have heard of, but it is generally limited to married couples. ElderLawAnswers explains how entireties, joint tenancy, and tenancy in common differ. For unmarried partners, the practical analysis is joint tenancy versus tenancy in common. State law on vesting varies, so a title company or attorney should confirm how your deed reads.
What the Federal Rules Add
Two federal rules explain why the note and the lien split the way they do. The Federal Reserve’s summary of Regulation B, the equal credit opportunity rule, says marital status does not matter for joint applicants. What matters is that the applicants intend a joint application and share liability. It also says a lender may take every joint applicant’s signature on both the note and the security instrument.
The same rule limits a lender’s ability to demand a third person’s signature when the applicant qualifies alone. A lender cannot require your partner to co-sign just because your partner exists. The exception is jointly owned collateral: a titled owner whose signature the lender needs to reach the property can be required to sign the lien document.
So qualifying alone removes the note signature for your partner. It does not remove the lien signature.
The Cancellation Right on a Primary Residence
A separate rule applies when the shared home is a primary residence and the loan is for personal use. Under CFPB Regulation Z § 1026.15, a HELOC on a principal dwelling carries a right of rescission, a short window to cancel after signing. That right extends to each consumer whose ownership interest is pledged, including a co-owner who is not a borrower.
One owner’s decision to cancel is effective for all. The right also applies to later credit limit increases. A partial transfer of the owner’s interest, such as adding a co-owner afterward, does not end it.
None of this applies to a rental. The right attaches to a security interest in a principal dwelling, not to a non-owner-occupied investment property, and a business-purpose loan generally falls outside it. A co-owner who lives elsewhere gets no cancellation right on a property that is not their home.
What the Network Actually Offers
Lendmire brokers home equity lines through select wholesale partners and is never the lender. Every figure below is subject to lender guidelines and full file review. The ceilings depend on occupancy, so the first question is how the property is used.
| Occupancy | Max CLTV | Credit minimum | Max line |
|---|---|---|---|
| Primary residence | Up to 90% at 720+ | 600 | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | Up to 90% at 720+ | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
On a primary residence, 90% CLTV exists only at 720 or better, and only on lines up to $500,000. Lower credit tiers step down from there. A 700-to-719 profile reaches 85% CLTV up to $500,000, and a 640-to-659 profile reaches 80%. On an investment property, the ceiling is 70% CLTV with no tier above it.
The lines are standalone and sit in first or second position. Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year repayment, and the other has a 5-year draw followed by a 25-year repayment. Investment lines run the 5-year-draw structure only. At least 75% of the line is drawn at closing, and pricing floats rather than converting to fixed.
Lines run from $25,000 up to $750,000. A line above $500,000 is for primary residences only. It needs a credit profile of 700 or better (720 on the 5-year-draw structure), caps at 75% CLTV, and requires a full appraisal. Lines at or below $500,000 ordinarily use an automated valuation instead.
Two eligibility points matter for unmarried partners. First, title must sit with an individual borrower or a revocable living trust. Second, a borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible. Availability covers 16 full-service states, which is narrower than Lendmire’s 41-market DSCR footprint, including Washington, D.C.
A Worked Example: One Partner Borrows
Picture two partners who hold title as tenants in common on the home they live in. Partner A has a 720-plus credit profile and a debt-to-income ratio low enough to qualify alone. Partner B has thinner credit and a smaller income.
If both applied, Partner B’s credit could pull the file down, and Partner B would share liability for the whole balance. Instead, Partner A applies alone, and Partner B signs the mortgage only. On a primary residence at that credit tier, Partner A’s file can reach the top of the CLTV range, subject to the existing first mortgage and the lender’s valuation.
Partner B does not owe the repayment. Even so, Partner B’s share of the house is pledged, and a default puts it at risk. Before closing, it is worth drafting a short written agreement on who draws, who repays, and what happens if one of you moves out.
Edge Cases Where the Basic Rule Bends
A partner on the deed refuses to sign. The lender generally will not close, because the lien cannot reach the whole property. Your realistic options are to buy out the partner, restructure title, or choose a different product that does not need the lien. Partition is a last-resort legal route.
A partner is on neither the deed nor the loan. A lender generally cannot force that person to sign if you qualify alone. If you do not qualify alone, a lender may ask for a co-signer, but it cannot insist the co-signer be a spouse.
A judgment lien against one owner. A creditor’s lien against one co-owner generally attaches to that person’s share, but it can cloud the whole title. Most lenders will want it paid or released before closing.
Re-titling after the fact. Adding a partner to the deed later makes that person a lien signer going forward. It does not undo what the original loan documents required.
Breakup. A divorce decree or a breakup does not change the deed. The line stays tied to whoever signed the note, and the lien stays on the property until it is paid off. If you sell or refinance, you will need all record owners to cooperate, so settle title before you settle the relationship.
Death of an owner. What happens next depends on how title was vested and on state law. A surviving joint tenant takes the whole property. A tenant in common’s share passes through their estate. In both cases, the debt does not vanish, so confirm the outcome with an attorney.
Where Investors Get Tripped Up
Many investors assume an equity line works on a rental the same way it works on a home. It works differently, in two ways.
First, the ceiling drops. A rental line on this network caps at 70% CLTV with a 700 credit minimum, versus up to 90% on a primary residence at 720 or better. Second, entity title is not allowed. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on an equity line. A property already deeded to an LLC needs a vesting change or a different product.
Some investors respond by pulling equity from the shared home before buying the next rental, while both partners are aligned and the property is still a primary residence. That sequencing works for many couples. It also means both of you are tied to the same line, so agree on how the money will be used first.
When a DSCR Cash-Out Refinance Fits Better
If the shared property is a rental, a DSCR cash-out refinance is often the cleaner tool. It is a business-purpose investor loan, reviewed differently from a standard owner-occupied mortgage. The loan is reviewed primarily on property-level rental income covering the full payment, subject to lender guidelines. Many investors also hold title in an LLC, subject to lender program eligibility.
Across most programs in the network, cash-out tops out around 75% LTV on standard long-term rentals. Short-term rental collateral generally runs lower, at about 70%. Roughly six months of seasoning is the common expectation. Coverage of 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. A 620 credit floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.
Clearing 1.00 does not mean the property produces positive cash flow. The calculation compares rent to the payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. Lendmire’s complete DSCR loans guide walks through the full qualification picture. For a couple, the DSCR route has another advantage: the choice of who holds title and who borrows can be settled before you pick the product.
What the Decision Looks Like in Practice
Start with the property’s use. A primary residence points toward an equity line at the higher leverage tiers. A rental points toward either a 70% CLTV investment line or a DSCR cash-out.
Next, decide who borrows. Qualify the stronger profile alone if you can, and have the other owner sign the lien only. Then check title: pull the deed, confirm how it is vested, and look for liens or unrecorded transfers. Last, write down the draw and repayment agreement between the two of you.
Settle all of this before you apply, because the lien signature binds both of you no matter who owes the debt.
Frequently Asked Questions
Can my unmarried partner and I both be on a HELOC?
Yes. Both of you can apply as joint applicants, and your income, credit, and assets are combined. Marital status does not matter for a joint application, according to the Federal Reserve. The tradeoff is that a joint borrower is generally liable for the whole balance, not half.
Can I get a HELOC without my partner as a borrower if we share the deed?
Often, yes, if you qualify alone. Your partner will still need to sign the mortgage that pledges the property, because the lender needs to reach the whole asset. That signature does not by itself make your partner personally responsible for repayment.
What does a lien-only signer risk?
The shared property. If the borrower defaults, the lender can pursue the collateral, which includes the lien-only signer’s interest. That person does not owe the repayment unless state law or the loan documents say otherwise.
What happens to the line if we break up?
The line stays with whoever signed the note, and the lien stays on the property. Neither a breakup nor a court order changes the deed on its own. Plan on needing every record owner to cooperate to sell or refinance.
Can I get an equity line on a rental we own together?
Sometimes. The network’s investment-property lines cap at 70% CLTV with a 700 credit minimum and a $500,000 maximum line. Title must be held by individuals or a revocable living trust, so an LLC-owned rental does not qualify. A DSCR cash-out refinance is the usual alternative.
