The Quick Read: A DSCR HELOC is reviewed on the rental’s income, so your first mortgage stays exactly as it is. The new line sits behind it as a standalone second lien. Through select programs, you need a 720 credit score or better, combined leverage up to 70% CLTV, and rent that covers a stress payment on the whole line at 1.10x or better, subject to underwriting. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
- Second lien: 720 minimum score, up to 70% CLTV, lines from $50,000 to $500,000.
- Coverage: rent divided by a stress payment on the entire credit limit, 1.10x minimum.
- Draw: at least 80% of the line is drawn at closing, so it is not a standby reserve.
- Seasoning: two six-month clocks apply, covered below.
- Footprint: 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
A cheap first mortgage is an asset worth protecting. Refinancing it to reach equity means repricing the whole balance. A second-lien line leaves that loan alone and adds a separate one behind it. This article walks through how the file is underwritten, what can break it, and when the structure is the wrong tool.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a revolving line of credit on a rental, qualified on the property’s rent instead of your personal income. It is written as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage.
A home equity line is an open-end credit line you can borrow against repeatedly. The CFPB’s overview of home equity lines describes a draw period followed by a repayment period. Here, the draw period runs 5 years interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
A few boundaries matter. The line 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. It covers non-owner-occupied one-to-four-unit rentals only. Vesting in your LLC is allowed on investment property, subject to program terms, with the members signing as guarantors.
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. For the broader picture, Lendmire’s complete DSCR loans guide covers the product family.
Key Terms Defined
DSCR: Debt service coverage ratio, meaning the rental’s gross monthly rent divided by the qualifying payment.
CLTV: Combined loan-to-value, meaning the first mortgage balance plus the new line, divided by the property’s value.
Second lien: A loan recorded behind your first mortgage, which is left untouched.
Stress payment: A fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, used only for qualifying.
Seasoning: How long you have owned or refinanced the property before the line is available.
What Do You Have to Show to Qualify?
You show a credit report, a lease, a valuation, and enough rent to clear the coverage test. You do not show tax returns, W-2s, pay stubs, or a debt-to-income ratio. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
| Gate | Second-lien requirement |
|---|---|
| Credit score | 720 or better |
| Leverage | Up to 70% CLTV |
| Line size | $50,000 to $500,000 |
| Coverage | 1.10x on the full-line stress payment |
| Property | Non-owner-occupied, 1-4 units |
| Seasoning | 6 months since last note date and 6 months on title |
| Reserves | None required |
Mortgage history matters too. Expect no 30-day late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu. Exposure is capped at 5 loans or $2,500,000 per borrower with the program. All of this is subject to underwriting.
Step by Step: How the File Is Underwritten
Underwriting moves through six checks, and the order matters because an early failure ends the file.
1. Confirm the first mortgage stays. The line is a new, separate lien. The first is not refinanced, and the borrowers on the line need not match the borrowers on the first.
2. Measure CLTV. Add the first mortgage balance to the new line and divide by value. A low first balance leaves more room under the 70% ceiling.
3. Pass the score gate. On a second lien, the lender’s own credit report must show 720 or better. Below that, there is no second-lien option.
4. Pass the coverage test. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. That rent must cover the stress payment on the whole line at 1.10x or better.
5. Clear valuation and title. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
6. Close and draw. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each.
A lease in place is required. A two-to-four-unit property may have at most one vacant unit. Title is a full policy on larger second liens above $400,000, and an owner-and-encumbrance report on smaller ones.
How Much Room Does a Low First Mortgage Leave?
A low first balance leaves the most room under the 70% CLTV ceiling, because the ceiling counts both loans together. A low interest rate on the first mortgage does not help CLTV at all. Only the balance matters.
Picture two owners of identical rentals. One carries a first mortgage near 35% of value. The other carries one near 60%. Both can reach a 70% combined ceiling, but the first has roughly 35 points of room and the second only about 10. The second owner may find the line too small to be worth it, even with the same excellent score.
So the rate on your first loan explains why you want to keep it. The balance determines how much line you can actually get. Those are two different questions, and it helps to keep them separate.
How Does the Coverage Test Treat the Line?
The test runs on a stress payment on the entire credit limit, not just the drawn balance. A larger line needs more rent to clear 1.10x, so line size can cap you before the CLTV ceiling does.
Take a rental whose rent clears a $100,000 line comfortably, around 1.3x on the stress payment. Ask for $300,000 and the same rent is spread over a payment three times as large. Coverage falls toward 0.43x, far below the 1.10x gate. The CLTV ceiling would have allowed the bigger line. The rent would not.
The qualifying payment is principal and interest on the full line at the stress rate. Taxes and insurance are not part of it. The lender’s own coverage calculation governs, so confirm on the file how the lender treats the first-mortgage payment on a second lien. Any arithmetic here is illustrative.
One more point on the next purchase. The line’s payment does not enter a new property’s coverage ratio, because it is a separate debt secured by a different property.
Will Your First Mortgage Allow It?
Check the first mortgage’s own documents before applying. Your note and security instrument can contain terms about additional liens, and the new line will sit behind that loan. Read them, and confirm the file is clear on title and insurance. Hazard insurance covers both liens, with flood coverage where required.
Vesting is the other paperwork point. If an LLC holds title, the members sign as guarantors, subject to program terms. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. By contrast, a bank-style line qualified on personal income generally wants the property in your own name. That is a different program with different rules.
Keep the First Mortgage or Replace It?
Keep it when the first mortgage is cheap and you need modest cash. Replace it when the equity you need exceeds what 70% CLTV allows, or when your score is under 720. A one-question test works: would repricing the entire balance cost more than carrying a second payment on a smaller line?
| Route | First mortgage | Qualified on | Fit |
|---|---|---|---|
| DSCR HELOC (second lien) | Stays | Rent | Low first balance, 720+ |
| DSCR cash-out refinance | Replaced | Rent | Score under 720, larger need |
| Bank-style HELOC on a rental | Stays | Personal income | W-2 borrower, personal title |
The line carries its own pricing and a second payment, and pricing on second liens differs from first liens. The rate and pricing terms come with the lender’s disclosures.
Second-lien programs set the credit floor higher than first-lien programs. Here the second lien starts at 720, and a first lien on a rental with no mortgage starts at 700.
Where the Rule Breaks
Several situations change the answer.
No mortgage on the rental. The line becomes a first lien. Leverage is up to 75% LTV at 740 or better, and 70% LTV from 700 to 739, on lines up to $500,000. Lines above $500,000, to $1,000,000, drop to 65% LTV at 720 or better. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Score under 720 with a mortgage in place. No second-lien cell exists. The realistic alternative is a cash-out refinance, which replaces the first mortgage.
Using the line as a reserve fund. Poor fit. At least 80% is drawn at closing and interest runs on it. The CFPB’s HELOC booklet also notes a lender can reduce a line if the home’s value drops.
Funding the next purchase. The line must exist before you go under contract. You cannot open one against a property you have not bought.
Ineligible property. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use, and a property listed for sale in the prior 2 months fall outside this program. A declining-market flag lowers the ceiling by 5 points.
Owner-occupied lines. A standard line on your own home is written for homeowners and may bar renting the property out. Never mix the two products.
Seasoning has its own rule. 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).
Common Reasons Files Stall, and the Fix
- Coverage short on the full line. Ask for a smaller line. Since the stress payment scales with the limit, trimming the request is the cleanest repair.
- CLTV too high. Pay down the first mortgage, or wait for value to rise, or shrink the line.
- Score at 700 to 719. The second lien is out. If the property has no mortgage, a first lien may fit. Otherwise a cash-out refinance is the fallback.
- Lease below market. Rent is the lesser of market rent and the lease, unless three months of receipts support a lease above market. Collect those receipts.
- Seasoning not met. Wait out the clocks.
Qualification stays subject to lender guidelines, credit approval, and property review.
Documents to Gather
- Current lease and recent rent receipts
- First mortgage statement
- Hazard insurance, plus flood coverage where required
- Entity papers and guarantor details if an LLC holds title
- Government ID and Social Security number (foreign nationals and ITIN borrowers are not eligible)
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.
Frequently Asked Questions
Can I keep my first mortgage and still get a DSCR HELOC?
Yes. The line is written as a standalone second lien, so the first mortgage is not refinanced and its terms stay as they are. The one requirement is that your combined balance, first mortgage plus the new line, stays within 70% of value, with a 720 score or better, subject to underwriting.
Does my personal income count?
No. The line is reviewed on the rental’s income: no traditional personal-income documentation, W-2s, or personal income calculation, subject to lender guidelines. The lease, credit report, and valuation are all documented.
How does seasoning work?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date).
Can an LLC hold title?
Yes, on investment property. The members sign as guarantors, per lender program requirements, and the borrowers on the line need not be the borrowers on the first mortgage.
Do program terms stay fixed?
No. Programs change, and every file is underwritten individually.
