The Quick Read: A DSCR HELOC is a revolving line of credit placed behind the first mortgage you already have, so the first loan stays exactly as it is. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and the owner’s personal income is never calculated. Only the new money is priced as new debt. Everything below is subject to underwriting and varies by borrower and property.
- The line is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage.
- Combined leverage on a second lien runs up to 70% CLTV at a 720 credit score or better, on lines of $50,000 to $500,000.
- Rent must cover a stress payment sized to the entire credit limit at 1.10x or better.
- The rate is variable, with a 5-year interest-only draw period, then a 25-year repayment period.
- Offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, through select programs. Leverage and final terms follow the full file review. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
An investor sitting on a cheap first mortgage has a real problem. The equity is there, but a cash-out refinance would replace the low first loan with a new one. A second lien avoids that. This piece walks through how the product is built, how underwriting treats it, and where it stops working.
What a DSCR HELOC Actually Is
A DSCR HELOC is a line of credit secured by a non-owner-occupied one-to-four-unit rental you already own. The rent qualifies the line. No traditional personal-income documentation, W-2s, pay stubs, or personal debt-to-income calculation enter the file, subject to lender guidelines.
It comes in two lien positions:
- Second lien. The line records behind the first mortgage you keep.
- First lien. The line sits alone on a rental that has no mortgage.
It is never closed together with a purchase. It is never a third lien. It is never placed on your own home or a second home. The LLC can hold title, subject to program terms, with the members signing as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line do not have to be the borrowers on the first mortgage.
Business-purpose investor loans like this one are reviewed differently from a standard owner-occupied mortgage. For the wider picture of how these loans work, see Lendmire’s complete DSCR loans guide.
Why the Low First Lien Survives
Because the line sits behind the first mortgage, only the new money is priced as new debt. The existing loan is not touched. A cash-out refinance does the opposite: it pays off the first loan and writes a new one on the whole balance.
That is the entire reason investors choose this structure. If the first loan is cheap, replacing it just to reach equity gives up something valuable.
One condition matters. The first mortgage’s own documents have to allow a junior lien. Most do, but an investor with unusual first-lien terms should read them before the file goes in. A second lien also does not trigger a prepayment penalty on the first loan, since the first loan is not being paid off.
How Underwriting Treats the File, Step by Step
Underwriting runs in a fixed order. Each step can stop the file.
1. Collateral. The property must be a leased, non-owner-occupied rental. A lease in place is required. A two-to-four-unit property may have at most 1 vacant unit.
2. Lien position. If a mortgage exists that you want to keep, the line goes second. If the property is free and clear, it goes first.
3. Combined leverage. CLTV is the first mortgage balance plus the new line, divided by value. The test uses the full line limit, not what you plan to draw. A line you intend to use lightly still counts at full size.
4. Coverage. Minimum DSCR is 1.10x. That is gross monthly rent divided by a qualifying payment. The qualifying payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a stress payment, built to test the property, not to predict what you will pay. Whether the first-mortgage payment joins that qualifying payment on a second lien is not something to assume either way; the lender’s own coverage calculation governs, so ask for it in writing before you size the line. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
5. Rent. The rent used is the lesser of the appraiser’s Form 1007 market rent or the lease. A lease above market counts only with three months of receipts.
6. Credit. The score comes from the lender’s own report. A second lien needs 720 or better. A first lien needs 700 or better. Mortgage history needs no 30-day late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
7. 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).
8. Valuation and title. Covered in its own section below.
How the ratio differs from commercial math
Commercial lenders usually measure coverage as net operating income divided by annual debt service. Residential investor programs generally use gross rent over the payment instead. Those are different tests with different cutoffs, so a number from one does not transfer to the other. The 1.10x here is a rent-over-stress-payment test.
Leverage Tiers
Second-lien leverage is simple. First-lien leverage has more steps.
| Position | Credit score | Maximum | Line size |
|---|---|---|---|
| Second lien | 740 or better | 70% CLTV | $50,000 to $500,000 |
| Second lien | 720 to 739 | 70% CLTV | $50,000 to $500,000 |
| First lien | 740 or better | 75% LTV | Up to $500,000 |
| First lien | 720 to 739 | 70% LTV | Up to $500,000 |
| First lien | 700 to 719 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000, to $1,000,000 |
There is no second-lien option below 720. All figures are ceilings, subject to underwriting, not offers.
Two adjustments apply. A declining-market flag lowers the ceiling 5 points. Philadelphia lines carry a ceiling 10 points lower.
Run the stack on a sample. Say a rental is valued at $400,000 and the existing first mortgage is 50% of value. At the 70% CLTV ceiling, the first loan plus the full line can reach 70% of value, so the line can be up to 20% of value. Now say the first mortgage is 65% of value. Only 5% of value is left, which is below the $50,000 line minimum on this property, so no line fits however strong the rent. Run the same check on your own balance before you apply.
Valuation, Title, and Draw Rules
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 need a full interior appraisal on Form 1004, 1073, or 1025. Appraisal waivers are not accepted.
Title. A full title policy is required on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report. Hazard insurance covers both liens, with flood coverage where required.
Draws. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each. The draw period is 5 years interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable. The rate and the pricing terms come with the lender’s disclosures.
That 80% initial draw is the detail investors miss. This is not a card you leave at zero. Most of the line is funded at closing, so the line fits an investor who has a use for the money.
Property and Borrower Eligibility
Eligible property types are single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres.
Not eligible on this program:
- rural-designated property
- row homes
- condotels
- commercial or agricultural property
- leaseholds and land trusts
- age-restricted communities
- hobby farms, modular homes, and log homes
- land contracts and mixed-use property
- a property listed for sale in the prior 2 months
- a property with a solar lien
Borrowers must be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. Exposure is capped at 5 loans or $2,500,000 per borrower with the program. No reserves and no cash to close are required.
Where the General Rule Breaks
The structure is clean on paper. These are the cases where it stops working.
Credit under 720 with a mortgage to keep. There is no second-lien cell below 720. The workarounds are a first-lien line, if the rental has no mortgage and the score is 700 or better, or a different program altogether.
A line already on the property. A second line behind an existing line would be a third lien. The program excludes it. The existing line has to be paid off first.
A first mortgage that bars junior liens. Rare, but it ends the file. Read the first-lien documents.
Rent that falls short on the full-limit test. Investors often size the line to what they want to draw. The test sizes it to the whole limit. A smaller line can pass where a larger one fails.
A recent rehab. An automated valuation may not capture work done recently. A full interior appraisal is the better path when the improvement drives value. BiggerPockets investors raise the same point about bank programs. An improvement may support a higher appraised value, depending on comps and underwriter review.
Short-term rentals. A lease in place is required here, so confirm how the rental is documented before applying.
Income documented through bank statements. An investor whose strength is documented personal income may do better with a bank statement HELOC. That is a different product with its own rules.
Recent purchase. An investor who bought five months ago waits. Plan the seasoning date before listing the line as a funding source for the next deal.
Why Banks Often Say No
Many investors try their own bank first. Availability is thin. BiggerPockets participants report that investment-property HELOCs are harder to find than home HELOCs, that some credit unions and regional banks still offer them, and that debt-to-income limits run tighter on investment property.
Some desks refuse a product called an investment HELOC but will write a similar line under another name. A separate BiggerPockets thread suggests asking for a line of credit secured by investment property.
Across Lendmire’s wholesale network, the pattern is consistent. When a bank desk declines or wants the full personal income file, a rent-qualified line is the usual next stop. Lendmire’s piece DSCR HELOC Lenders for Investors Keeping a Low First Lien looks at how those placements are sourced.
What the Investor Decision Looks Like
The decision comes down to cost of the whole stack and what the money does.
Blended cost. Pricing only new money against a low first loan usually beats refinancing everything. But a very cheap first loan plus a more expensive second can cost more overall than it first appears. Work out the blended cost of the whole stack, not just the headline on the line. A banker on BiggerPockets makes the same point.
Use of funds. Common uses are the down payment on the next building, rehab on a current one, or a cash cushion. That plan carries risk if a later refinance does not happen.
Variable rate and payment reset. The rate moves. Interest-only ends after 5 years, and the payment steps up when amortization starts. Underwrite your own cash flow with that step in mind, not only the lender’s stress test.
Stacked leverage. A second lien adds debt against the same building. A vacancy or a repair bill lands on a property with less cushion than before. Leave room.
Interest-only carry. Interest accrues on the drawn balance. With at least 80% of the line drawn at closing, the carry starts immediately. Do not treat the line as free money.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
A quick comparison
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| What gets repriced | New money only | Whole balance |
| Structure | Revolving line, variable rate | Closed-end loan |
| Lien position | Second (or first if no mortgage) | First |
| Best fit | Cheap first loan worth keeping | First loan has no value to keep |
The refinance can still be the better choice when the first loan is not cheap, or when the investor wants one fixed payment.

Frequently Asked Questions
Can I keep my first mortgage and still open a DSCR HELOC?
Yes, that is the main use. The line is written as a standalone second lien behind the first mortgage you keep, and the first loan is not paid off or repriced. The first lender’s documents must permit a junior lien, and the combined balance must fit under the 70% CLTV ceiling at a 720 score or better, subject to underwriting.
Does the line qualify on my personal income?
No. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The rent has to reach 1.10x against a stress payment sized to the entire credit limit. Rent used is the lesser of the appraiser’s market rent or the lease.
Can an LLC hold the property?
Yes, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line do not have to match the borrowers on the first mortgage.
What stops a file most often?
Credit under 720 on a second lien, rent that falls short on the full-limit test, a combined balance that leaves no room under the 70% ceiling, and ineligible property types such as condotels or rural property. Seasoning also catches recent buyers.
Where is the program offered?
It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, through select programs. Lendmire is a broker arranging the line through a wholesale lender in its network. Programs change, and every file is underwritten individually.
