The Quick Read: Usually up to 70% combined loan-to-value on the whole property, first mortgage included, and the line tops out at $500,000 on an investment property through select lenders in Lendmire’s wholesale network. Every titled owner generally has to sign the lien, whether or not that owner borrows. Co-ownership changes who signs and whose credit counts. It does not change the borrowing math.
- The ceiling: 70% CLTV on an investment property, with a 700 minimum credit score. A 720 score earns eligibility at the same 70%, not extra leverage.
- The math: the lender tests the whole property’s value against the whole property’s debt, never just your share.
- The income: a co-owner’s income counts only if that person is also a borrower.
- The exposure: a co-owner who signs the lien puts their equity at risk, even if they never touch the money.
- The workaround: if title sits in an LLC, a DSCR cash-out refinance often becomes the better tool.
How the Limit Is Calculated
The limit is the property’s value times the lender’s combined loan-to-value (CLTV) cap, minus what is already owed on the first mortgage. NerdWallet’s explainer uses the same method: the equity a lender allows, less the remaining mortgage balance, equals the most you can borrow.
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.
CLTV means combined loan-to-value. It adds every loan secured by the property, then divides by the property’s value. A first mortgage plus a new line both count.
Here is the method in three steps:
1. Take the property’s value.
2. Multiply it by the lender’s cap. On an investment property in this network, that cap is 70% CLTV.
3. Subtract the first-mortgage balance. The remainder is the ceiling on the line.
Percentages keep it clean. Say the first mortgage equals 55% of the property’s value. The room under a 70% cap is 15% of value.
Now apply it to co-ownership. Two owners do not each get a separate 70% of their half. The lender appraises or values the entire property and counts the entire debt. Equity is a property-level number.
This is why a share-only calculation fails. Lenders avoid a lien on one owner’s undivided share, because they could not easily sell or foreclose on a partial interest. They take the whole property as collateral, and that requires the whole title.
What the Network Allows on an Investment Line
Select lenders in the network place investment-property lines with these typical terms. Each is subject to lender guidelines and full file review, and none is a commitment to lend.
| Feature | Investment property line |
|---|---|
| Maximum CLTV | 70% |
| Credit score | 700 minimum |
| Line size | Up to $500,000 |
| Draw structure | 5-year draw, 25-year repayment |
| Valuation | Usually automated, no appraisal |
| DTI | 50% maximum |
The credit tiers are flat at the top. A 720 score and a 700 score both reach 70%. Credit above 700 does not raise your limit, and 700 is a hard floor with no tier beneath it.
At least 75% of the line is drawn at closing. The line sits in first or second lien position.
Primary residences and second homes follow a different table. Those lines can reach 90% CLTV, but only at a 720-or-better credit profile. That higher ceiling does not apply to a rental, and a co-owned rental never inherits it.
Why Rental Lines Are Narrower
A HELOC (home equity line of credit) is a revolving credit line secured by the property. You draw, repay, and draw again during a set period. The Consumer Financial Protection Bureau describes it as open-end credit and defines equity as the home’s value minus what you owe on the mortgage.
Rentals are harder to place than primary homes. Many large retail lenders decline rental collateral entirely. BiggerPockets members report that banks often turn down rentals and sometimes respond better when you ask for a line of credit rather than a HELOC.
That supply problem is why caps run lower. The network’s investment ceiling sits at 70% CLTV, below the tiers available on a primary home.
Two program facts matter for rentals:
- Valuation: a line capped at $500,000 is structurally always in the automated-valuation lane. A traditional appraisal is not required, though a borrower can request one.
- Property types: single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
A standard HELOC also does not qualify off rent. It runs on personal credit, debt-to-income (DTI), and equity. That is the sharpest contrast with a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
What Changes When Two Owners Share Title
Co-ownership changes three things: signatures, underwriting, and liability. The limit stays the same.
Signatures. Lenders generally require every owner on title to sign the security instrument. The security instrument is the document that pledges the property. A co-owner who never borrows still signs it.
Underwriting. If one owner borrows, that owner’s credit, income, and debts drive the file. If both borrow, both are underwritten and the lender judges the blend. The existing first mortgage counts in the DTI test either way.
Liability. The lien and the note are different documents. The lien pledges the property. The note is the promise to repay. Some lenders let a co-owner sign the lien without signing the note, and others insist both owners borrow. That varies by lender.
A non-borrowing signer owes nothing personally if they stay off the note. Their equity is still exposed, because a default lets the lender foreclose on the whole property.
Three Co-Owner Scenarios Side by Side
| Scenario | Who signs the lien | Whose credit counts | Who owes the debt |
|---|---|---|---|
| One owner borrows | Both owners | Borrower only | Borrower (note) |
| Both owners borrow | Both owners | Both, blended | Both owners |
| Co-owner refuses | Only one | File generally stops | Not applicable |
The first row keeps the co-owner’s credit out of the file, which suits a cooperative co-owner who prefers not to borrow. It is harder to place, though, because it needs a lender that allows a signer who is off the note. The second row is the most common structure, but it lets the weaker credit profile pull down the whole file.
The third row is where many deals end. If one titled owner will not sign, the line generally cannot close.
Title Types and Edge Cases
Joint tenants and tenants in common both generally need every owner to sign. A tenant in common holds a defined share and can often pledge only that share. Lenders want the whole property as collateral, so they still ask for every owner.
Spouses are the simplest case. If both are on title, both generally sign. Divorce adds a wrinkle, because the property is typically treated as marital until the court finalizes the division. Unmarried partners, siblings, and friends follow the same sign-the-lien rule.
- A quitclaim deed does not release a co-owner from a loan. It moves title and leaves the debt alone. The departing owner comes off the loan through a payoff, a refinance, or the lender’s formal release.
- Money moving between co-owners is not income. Deposits from the other owner, such as reimbursements, rent shares, or buyout money, typically get stripped from bank-statement income analysis.
- Business bank accounts need at least a 680 score for the deposit analysis. Investment lines already floor at 700, so bank-statement income is never the binding constraint on a rental line.
Title Held in an LLC or Trust
On an equity line, title must sit with the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest structural difference from a DSCR loan.
If your rental is already deeded to an LLC, you have two paths. You can change the vesting into your own name or revocable trust, or you can use a DSCR cash-out refinance, which can work for LLC-titled properties, subject to lender program eligibility.
When a Co-Owner Won’t Sign
Four exits exist. Pick the one that matches your real goal.
1. Buy the co-owner out. You become the sole owner and sole signer. This works only if you can fund the buyout.
2. Retitle the property. Possible only with the co-owner’s cooperation, and a transfer can affect the existing first mortgage.
3. Borrow against a different property you own alone. The refusing co-owner is no longer a gate.
4. Switch products. A DSCR cash-out refinance needs every titled owner too, so it fixes the qualification question but not the signature question.
The Risks Both Owners Take On
A default lets the lender foreclose on the property. The CFPB warns that you could lose your home if you fall behind, and a lender may also restrict further draws if the value falls significantly. On a rental, the collateral is the rental, but a lien signer’s equity is exposed even if they never borrowed.
The structure adds its own pressure. A line starts with an interest-only draw period. The investment structure here runs five years of draw, then a 25-year fully amortizing repayment. The payment steps up when repayment begins.
The lender reviews your file on the interest-only payment calculated on the maximum draw. It does not qualify you on the payment after repayment begins. Budget for the step-up before you draw.
Some limits also apply to your whole portfolio. A borrower is limited to three lines, and a borrower owning more than 15 financed properties is not eligible. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure needs seven years, and a deed-in-lieu, pre-foreclosure, or short sale needs four.
Equity lines through this network are placed in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
When a DSCR Cash-Out Beats the HELOC
A HELOC is the right tool when you want revolving access, you hold title personally, and your first mortgage leaves real room under 70% CLTV. A DSCR cash-out refinance is often the better tool for a pure rental.
Here is why the two products differ:
- A DSCR cash-out replaces the first mortgage. A HELOC sits behind it or beside it.
- A DSCR loan is reviewed on the rent. It compares monthly rent to PITIA, which is principal, interest, taxes, insurance, and any association dues.
- A DSCR loan takes a lump sum. A HELOC gives a revolving balance.
- A DSCR loan can fit entity title. A HELOC cannot.
Typical DSCR cash-out terms across select lenders in the network look like this:
- Leverage: up to about 75% LTV on a cash-out refinance of a standard rental, and around 70% on a cash-out refinance of short-term-rental collateral.
- Seasoning: about six months of ownership is the common expectation.
- Coverage: 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better leverage and pricing.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest tiers.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).
- Reserves: these vary by lender, leverage, and loan size, and commonly run around six months of PITIA.
A DSCR ratio clears 1.00 when rent covers PITIA. That is not the same as positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation.
Co-owners should note the catch: every titled owner still signs. If your co-owner will not sign a HELOC lien, they will not sign a DSCR deed of trust either. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.

Pre-Application Checklist for Co-Owners
Have these conversations before you apply, because the answers decide which product fits:
- Title: who is on it, in what form, and whether any owner is an entity.
- Roles: who borrows, who signs the lien only, and whether the lender allows that split.
- The first mortgage: its balance, since it eats room under the CLTV cap.
- Credit: a 700 minimum for an investment line, from a single-bureau score model keyed to the primary wage earner. The report must be no more than 90 days old at closing.
- Documents: a credit report, income documents, a valuation, and the security instrument signed by every titled owner. A non-borrowing owner may also sign an acknowledgment that the property is pledged but the debt is not theirs.
- Exit plan: what happens at the end of the five-year draw, and who pays the repayment-period balance.
Key Terms Defined
CLTV (combined loan-to-value): the total of all loans secured by the property, divided by the property’s value.
Lien: a legal claim on the property that lets the lender foreclose if the loan goes unpaid.
Note: the signed promise to repay the loan. A person who signs the note owes the debt.
Tenants in common: co-owners who each hold a defined share and can each leave that share to heirs.
Joint tenants: co-owners who hold equal shares, with the surviving owner taking the whole property.
Draw period: the stretch when you can borrow from the line, followed by the repayment period when you pay it down.
Frequently Asked Questions
Does the limit use my share of the property or the whole property?
It uses the whole property. The lender multiplies the full value by its CLTV cap and subtracts the full first-mortgage balance. Co-ownership does not split the calculation, and a lender that would lend against only one owner’s undivided share is rare.
Can I borrow without my co-owner’s signature?
Generally no. Lenders need every titled owner to sign the lien, because they want the whole property as collateral. If a co-owner refuses, the file generally stops, and your options become a buyout, a retitle, a different property you own alone, or a different product.
If my co-owner signs, do they owe the debt?
Only if they also sign the note. Signing the lien pledges their equity, and signing the note makes them personally liable. Whether a co-owner can sign the lien and stay off the note varies by lender.
Does my co-owner’s income raise my limit?
No. Your limit comes from the property’s value, the CLTV cap, and the first-mortgage balance. A co-owner’s income helps qualify the file only if that person is also a borrower, and it does not lift the 70% ceiling or the $500,000 cap.
What if my rental is owned by an LLC?
An equity line cannot be placed on LLC-held title, because only an individual or an inter vivos revocable living trust can hold title. You can change the vesting or move to a DSCR cash-out refinance, which can fit entity title subject to lender program eligibility.
