The Quick Read: On a second lien against a rental, the line runs up to 70% combined loan-to-value, minus the first-mortgage balance and other liens, up to $500,000, if rent covers the stress payment at 1.10x, subject to underwriting.
- Rent can limit the line before equity does. The rent test runs on the entire credit limit.
- Every owner on title signs the lien. Only the borrower signs the note.
What Does “Not on the Mortgage” Actually Mean?
The phrase has two readings, and the answer differs slightly for each. In the first, you are the borrower on the new DSCR HELOC, but someone else signed the existing first mortgage. In the second, you hold title to the rental but are not a borrower on the line at all.
A DSCR HELOC is a revolving line of credit on a non-owner-occupied rental. It sits as a standalone second lien behind the first mortgage the owner keeps. On a rental with no mortgage, it can sit as a first lien. Across the wholesale network Lendmire works with, the borrowers on the line do not have to match the borrowers on the first mortgage.
Three separate roles get mixed up here: being on the note, being on title, and signing the lien. Keeping them apart answers most of the confusion. The table asks one question of each role: does it set your dollar cap?
| Role | What it means | Does it set your cap? |
|---|---|---|
| On the note | You promise to repay the line | No |
| On title | You are an owner of record | No |
| Signing the lien | You pledge the property as security | No |
Signing the lien still matters, because every owner on title signs it, while only the borrower signs the note. That signature secures the line but adds nothing to the ceiling. The ceiling comes from value, existing liens, credit tier and rent.
How Much Can You Borrow on a Second Lien?
On a second lien, the maximum is 70% combined loan-to-value (CLTV) on an investment rental, minus the first-mortgage balance and any other liens. The line must also fall between $50,000 and $500,000. A borrower needs a 720 credit score or better to qualify for this tier.
Here is the formula in plain words: take the property value, multiply by 70%, then subtract everything already recorded against the property. What is left is the most the line could be, before the rent test and the other limits below.
Run the numbers in percentages. Say the first mortgage sits at 50% of the property’s value. Then 50% plus a new line of up to 20% of value reaches the 70% ceiling. If the first mortgage sits at 60%, the room shrinks to 10% of value. Any other second lien counts too.
Two practical points follow from that math.
- A big first mortgage can shrink the line below the floor. If the room left is under $50,000, there is no line to write.
- The dollar cap binds on expensive properties. On a high-value rental with a small first mortgage, the $500,000 maximum stops the line before the 70% ceiling does.
A declining-market flag on the property can lower the ceiling by 5 points.
When the Rent Test Sets the Limit Instead
Rent must cover a stress payment on the whole credit limit at 1.10x or better. That is the debt service coverage ratio, or DSCR: gross monthly rent divided by the qualifying payment. The qualifying payment is a fully amortizing principal-and-interest payment on the entire line at the start rate plus 2 percentage points. It is used only for qualifying, and taxes and insurance are not part of it.
The test runs on the full limit, not just the amount you plan to use. So a larger line makes the test harder to pass. With only the line’s payment in the math, a line twice as large cuts coverage roughly in half. Whether the first-mortgage payment joins that math on a second lien is not something to assume, so confirm on the file how the lender treats it. The lender’s coverage calculation governs.
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 must be in place. A two-to-four-unit property may have at most one vacant unit.
So the real limit is the lowest of four numbers: the CLTV room, the $500,000 cap, the line size the rent supports, and the closing draw rule covered below. This program qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It uses no traditional personal-income documentation, W-2s or personal income calculation. That is why a spouse, partner or co-owner with thin income does not need to be a borrower.
What If the Rental Has No Mortgage?
Then the line can be a first lien, and the leverage is on loan-to-value (LTV) rather than CLTV. On a rental with no mortgage, a first lien on lines up to $500,000 reaches 75% LTV at a 740 score or better. From 700 to 739 it reaches 70% LTV. The first-lien floor is 700.
Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Every first-lien figure is subject to underwriting. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
One more rule trips people up. A first lien exists only on a rental with no mortgage. If you keep a first mortgage, you take a second lien, and that carries the 720 floor.
Who Has to Sign What?
The borrower signs the note. Every titled owner signs the mortgage or deed of trust. Each owner who is not borrowing also signs a non-borrowing owner acknowledgment. The non-borrowing owner takes on no debt, but the property they co-own secures the line.
| Your situation | Can the line go ahead? | Who signs |
|---|---|---|
| Sole owner | Yes | You: note and lien |
| On title, off the first mortgage | Yes | You: note and lien |
| Co-owner on title, not borrowing | Yes | Borrower: note; all owners: lien |
| Spouse off title | Depends on state law | Varies by state |
| LLC member | LLC borrows; members guarantee | LLC and members |
| Heir or ex-spouse still on deed | Only if they sign | Every name on title |
A non-borrowing spouse’s income is not used, and their credit is not reviewed. Whether a spouse who is off title must sign depends on state law. Many common-law states do not require a non-titled spouse to sign for a rental. Community-property states may require the signature. A title company or real estate attorney can tell you which rule applies where the property sits.
Federal spousal-signature rules point the same way. FDIC guidance on spousal signatures explains that where a non-applicant joint owner’s signature is needed to reach the property, the creditor may require it only on the document necessary to satisfy the debt. In plain terms, a lender can ask a co-owner to sign the lien, not to take on the loan. That guidance is dated and uses older rule numbering, so treat it as a general explanation.
Title that has not caught up with life is the usual snag. After a divorce decree, the county record changes only when a deed or a properly worded order is recorded. Until then, an ex-spouse is a required signer. The same goes for an heir whose name is still on the deed.
If a co-owner will not sign, the line cannot proceed with that owner on title. Your options are to change title through a recorded deed or to wait until the owner agrees. Have an attorney review any title change first.
What if the rental is titled to your spouse alone? Then the spouse borrows, or title changes. You cannot pledge a property you do not own.
An LLC can stay on title on investment property, depending on program guidelines. The members sign as guarantors. Many personal-income HELOC programs are not built for LLC title, so this is a real advantage of a rent-qualified line.
The Rest of the File
These rules apply to every borrower, whatever the roles above.
Draws and terms. The line is a variable-rate revolving line with a 5-year interest-only draw period on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. 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 the whole line is drawn at closing. Later draws are at least $5,000 each. This is not a standby reserve you leave mostly untouched.
Valuation. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted.
Seasoning. 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). If you recently inherited or were added to a deed, check the title clock before you plan around this line.
Credit. The minimum is 720 on a second lien and 700 on a first lien. The program wants no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required. One borrower can have at most 5 loans or $2,500,000 with the program.
Property and borrower. Eligible properties include single-family, PUD, townhome, two-to-four-unit and condominium rentals. Rural property, row homes, condotels, leaseholds, mixed-use and land trusts are outside the program. So are properties listed for sale in the prior 2 months. U.S. citizens, permanent residents and non-permanent residents with a Social Security number can apply. Foreign nationals and ITIN borrowers cannot.
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. Regulation Z § 1026.3 treats credit to maintain a non-owner-occupied rental as business-purpose, unless the owner expects to occupy it more than 14 days in the coming year.

Is a DSCR HELOC the Right Move for You?
It fits an investor who wants to reach a rental’s equity without touching the first mortgage and without opening a personal income file. A cash-out refinance replaces the first mortgage. The line sits behind it, so a first mortgage you like stays in place.
Personal-income lines are a different product. NerdWallet’s explainer on HELOCs for investment property notes that they are stricter than home-equity lines on a primary residence. A personal-income line is underwritten on the borrower’s credit and debt-to-income. It is a separate product with different rules, so do not assume its terms carry over to this one.
Several limits matter before you commit:
- The line is for a rental you already own. It does not close with a purchase, so it cannot buy a property you do not hold.
- Set it up before you go under contract on the next property. The purchase lender can then judge the new loan mostly on that property’s rent.
- Each line attaches to one property. Equity does not pool across rentals.
- A second lien has to be cleared before a cash-out refinance of that property.
- An existing DSCR first mortgage has to allow a junior lien. Read the documents first.
If you want the personal-income side of this question, Lendmire’s piece How to Qualify for an Investment Property HELOC When You’re Not on the Mortgage covers that product separately.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment. This program wants 1.10x or better.
CLTV (combined loan-to-value): the first-mortgage balance plus the new line, divided by the property’s value.
Note: the signed promise to repay. Only the borrower signs it.
Lien: the recorded claim on the property that secures the debt. Every titled owner signs it.
Vesting: how title is held, such as in your name or in your LLC.
Non-borrowing owner: someone on title who does not owe the debt but signs the lien and an acknowledgment.
Frequently Asked Questions
Can I borrow if I’m on the deed but not on the first mortgage?
Yes. The program does not require the borrowers on the line to match the borrowers on the first mortgage. The lender counts the first-mortgage balance against your CLTV room, whoever signed it. You still need to meet the credit tier, the rent test and the title and seasoning rules, subject to underwriting.
Does the other borrower’s credit or income affect my line?
No. Your own credit report sets your tier, and the rent qualifies the line. A non-borrowing owner’s credit is not reviewed and their income is not used. They still sign the lien and the acknowledgment if they are on title.
What if I’m not on title at all?
You cannot pledge property you do not own, so the owner has to borrow or title has to change. For a spouse who is off title, state law decides whether a signature is needed. Ask a title company or attorney in the property’s state before you plan around either path.
Why is my line smaller than the equity I thought I had?
Three things shrink it: the first-mortgage balance and any other liens, the 70% CLTV ceiling on a second lien, and the rent test on the full limit. Equity above 70% of value is not available on a second lien. A first lien on a rental with no mortgage reaches 75% LTV at 740 or better. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Can the line pay for the next rental at closing?
No. The program does not close together with a purchase, and the line must be on a rental you already own. Open it before you go under contract, then use the funds toward the next purchase. At least 80% of the line is drawn at closing, so plan the draw around that.
