The Quick Read: It depends on the whole property and its rent, not your ownership share: the line is the home’s value times the allowed combined leverage, less the first mortgage, then trimmed until rent covers the stress payment. Every titled owner generally has to sign the lien. Shared title changes who signs. It does not change how the line is sized.
- A second-lien line reaches up to 70% combined loan-to-value (CLTV) at a 720 score or better, on lines from $50,000 to $500,000, subject to underwriting.
- A rental with no mortgage can take a first-lien line: up to 75% loan-to-value (LTV) at 740 or better, 70% from 700 to 739, and 65% on lines above $500,000, which run to $1,000,000.
- The rental’s income qualifies the file at a 1.10x minimum coverage. Your co-owner’s income and credit stay out of it unless they join as a co-borrower.
How the Line Size Is Set
A DSCR HELOC is a revolving line of credit secured by a rental you keep. It qualifies primarily on the property’s rental income covering the payment, subject to lender guidelines. Think of the line as the smallest of three numbers: what leverage allows, what rent can carry, and the program’s dollar limits.
Start with leverage. Take the home’s value and multiply it by the allowed CLTV, which is the first mortgage balance plus the new line, divided by value. Subtract what you still owe on the first mortgage. What remains is the most the line can be.
Here is the picture in percentages. Say the first mortgage sits at 50% of the home’s value, and you hold a 720 score. At 70% CLTV, the line can reach 20% of value. If 20% of value comes to less than $50,000, the minimum line, no line fits. If it comes to more than $500,000, the second-lien ceiling caps it there.
The lender counts the full credit limit, not the amount you plan to draw. You could draw all of it, so the file is sized as if you will.
Now the dollar limits. Lines start at $50,000. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means drawing the whole line. Later draws are at least $5,000 each. This is a borrowing tool, not a standby cushion you leave mostly unused.
Does Your Ownership Share Change the Number?
No. Value and liens belong to the whole property, so the formula never looks at your percentage. Co-ownership matters for signatures and for how the owners divide the money, not for the sizing.
Run two cases with modeled assumptions. In the first, two siblings hold title 50/50 and the first mortgage sits at 45% of value. In the second, two partners hold 60/40 with the same first mortgage. Both files get the same leverage room: 25 points of value at 70% CLTV. Each owner’s share is irrelevant to that math.
A third case: the rental has no mortgage and a 740 score applies. A first-lien line can reach 75% LTV on lines up to $500,000. Lines that big take a full interior appraisal. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
The existing first mortgage stays in place, joint or not. A joint first mortgage is not a problem for a second-lien line, because the new line sits behind it. The borrowers on the line need not match the borrowers on the first mortgage. Still, the first-mortgage balance eats leverage room whoever owes it.
Who Has to Sign? Note vs. Lien
Two documents matter. The note is the promise to repay. The lien (a mortgage or deed of trust) pledges the property as collateral. The borrower signs the note. Every titled owner signs the lien.
| Situation | Signs the note | Signs the lien |
|---|---|---|
| One borrower, co-owner on title | Borrower only | Every titled owner |
| Both owners borrow | Both owners | Both owners |
| LLC holds title | LLC, members guarantee | Title holder, per lender |
| Spouse off title | Borrower only | Only if state law requires |
A co-owner who signs only the lien takes on no repayment duty. Their share of the property is still pledged. If the borrower stops paying, the lien can reach that share. A title holder who is not a borrower also signs a non-borrowing owner acknowledgment on this program.
The lender can ask a co-owner to sign the lien because federal law draws a line between the credit instrument and the security. Federal law bars a lender from requiring a second signature on the credit instrument when the applicant qualifies alone, as the Consumer Financial Protection Bureau’s rule on signatures explains. The same rule, in its eCFR text, lets a lender require the signatures needed under state law to make secured property available. In plain terms: nobody can force your co-owner onto the note, but the lender can ask them to sign the lien.
Can you borrow against just your half? The law of co-ownership says a co-tenant can mortgage their own share but cannot pledge the others’ shares, as Nolo’s joint property overview lays out. In practice, a lender holding a fractional lien would be stuck with a share that is hard to sell. A buyer of that share becomes a co-owner and may seek to split the property. So whole-property lines expect every owner to sign. Plan on it.
For the mechanics of the application itself, Lendmire’s piece How to Open a HELOC on a Co-Owned Home With Shared Title covers the owner-side steps.
Key Terms Defined
Title (vesting): how the deed names the owners, such as individuals, a married couple, or an LLC.
Note: the signed promise to repay the borrowed money.
Lien: the document that pledges the property as security for the note.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the home’s value.
DSCR (debt-service coverage ratio): gross monthly rent divided by the qualifying payment. This program wants at least 1.10x.
Co-borrower: an owner who signs the note and whose credit goes on the file. A lien-only signer is not one.
What the Rent Test Does to a Co-Owned Line
The rent test is where many co-owned lines shrink. The qualifying payment is principal and interest on the entire credit limit, amortized fully at a stress rate above the starting rate. Taxes and insurance are not part of that payment. Rent must cover it at 1.10x or better.
Which rent counts? Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. A two-to-four-unit property may have at most one vacant unit.
For a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The program does not publish a formula for that. Ask early, because it can change the answer.
Here is the practical lever. Because the test runs on the full limit, a high limit can drag coverage below the minimum even when leverage allows more. Dial the limit down, and the stress payment drops, so the ratio rises. A smaller line than your equity would allow is a normal outcome, not a failure.
Neither owner’s personal income is calculated. That helps self-employed investors and partners with messy tax returns. The trade-off is the coverage test and the credit tier. The tier uses the borrower’s own credit report. A lien-only co-owner’s credit is not counted.
If you add the co-owner as a co-borrower, their debts and credit go on the file. That adds underwriting. It does not raise the line, because the leverage cap is set by the program tier and the home’s value, not by how many borrowers sign.
Across the wholesale network Lendmire places files with, the leverage tiers work as ceilings, not offers. A stronger score can open a tier. It does not stretch the tier.
Co-Owner Won’t Sign (Now What?)
One uncooperative owner can block the line even when you qualify alone. Your options:
| Option | What changes | The catch |
|---|---|---|
| Buyout | You hold title alone | Needs cash to pay out the owner |
| Retitle by deed | Names on title change | Recent deed changes show on title review |
| Line on another rental | No signature issue | Needs its own equity and rent coverage |
| Cash-out refinance | Replaces the first mortgage | Generally needs every owner too |
A DSCR cash-out refinance is not a workaround. It replaces your first mortgage, so you give up the existing first-lien payment. It also generally needs every titled owner to sign.
It is also the most expensive. Which one wins depends on how much equity you want and how much you trust your co-owner.
Edge Cases Worth Knowing
Tenancy in common with unequal shares. The law lets each owner pledge only their own share. Lenders still want the whole property, so every owner signs.
Joint tenancy. That is a state-law question. Talk to an attorney before anyone signs.
Spouse off title. Signatures can be required under state law, such as community-property or homestead rules, even when the spouse is not on the deed. The rule differs by state. Ask the title company early.
LLC title. This program allows vesting in your LLC, subject to program terms. The members sign as guarantors. Land trusts are not eligible.
Inherited property. The deed has to be recorded to the heirs first. A line generally is not possible while probate holds title.
Divorce or court orders. Court restraints can block new debt. Settle title questions before you apply.
What Else the File Needs
The valuation path depends on size. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted.
Two clocks cover seasoning, the wait before you can borrow. A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
Credit: a second lien needs 720, a first lien needs 700. There is no 30-day mortgage late in the last 12 months. There must be 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required. Each borrower can have at most 5 loans or $2,500,000 with the program.
Property: single-family, townhome, planned unit developments, condominiums and two-to-four units are eligible. Rural property, condotels, row homes and leaseholds are not. 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.
Citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
All of this is subject to underwriting, and the lender’s own calculation governs.
One Borrower or Both?
Choose one borrower when that owner carries the credit and the coverage. The co-owner signs the lien and the acknowledgment, and nothing else. It keeps their credit and debts out of it. The owners should still write down who draws, who pays, and how rent and proceeds are split. The line is secured by the whole property, so a missed payment puts everyone’s share at risk.
Choose both borrowers when one owner’s credit falls under the tier. Then both owners’ credit is reviewed. Joint repayment duty follows. Know that going in.
A co-owner’s tight finances are a risk worth sizing. Nolo’s guide to co-owning a home notes that with a single mortgage on the whole property, all owners must qualify together and all are at risk if one falls behind. A line tied to the whole property works the same way in practice.
Before You Apply: A Checklist
- Pull the deed and confirm exactly how title is vested.
- Confirm both six-month clocks have run.
- Get the lease and, if the lease is above market, three months of rent receipts.
- Get the first-mortgage balance.
- Check your credit tier: 720 for a second lien.
- Get a written owner agreement on draws, payments, and rent split.
- Ask each titled owner whether they will sign the lien before you pay for anything.

Frequently Asked Questions
Can I borrow against only my half of a co-owned rental?
Rarely, in practice. The law lets a co-owner pledge their own share, but whole-property lines expect every titled owner to sign the lien. The line is sized on the whole property’s value and liens, so your percentage does not set the ceiling.
If my co-owner signs the lien, are they responsible for the debt?
No. Only the note creates a repayment duty, and the borrower signs it. The lien-only signer still pledges their share of the property, so an owners’ agreement should address that.
Do my co-owner’s income and credit help me qualify?
Only if they join as a co-borrower. Otherwise the file runs on the rental’s income and your credit. A co-borrower adds underwriting but does not raise the leverage cap.
Can an LLC hold title on a co-owned rental line?
Yes, subject to program terms. The members sign as guarantors, and any title holder who is not a borrower signs the acknowledgment and the lien. Land trusts are not eligible.
What is the biggest line I can get on a rental with no mortgage?
Lines run to $1,000,000 on a first lien. Up to $500,000, a first lien reaches 75% LTV at 740 or better and 70% from 700 to 739. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
