The Quick Read: The best program for you is a standalone second lien that sits behind your existing first mortgage and is reviewed on the rental’s rent, not your personal income. Your first loan keeps its rate, term and payment because the new line never touches it. Through select programs in Lendmire’s wholesale network, a second lien reaches 70% combined loan-to-value at a 720 credit score or better, subject to underwriting. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
- A second lien leaves your first mortgage alone. A cash-out refinance pays it off and replaces it.
- The rent qualifies the line at a minimum 1.10x coverage, tested on a stress payment over the whole credit limit.
- Your low rate protects your cost. It does not add borrowing room, because only the balance counts.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Lendmire is a mortgage broker, not a lender. It places these lines through wholesale lenders and matches the property to the program. The best program for your situation depends on your credit tier, your first-mortgage balance, the property type and how much you need to draw.
What Is a DSCR HELOC?
A DSCR HELOC is a revolving line of credit secured by a rental you own. DSCR stands for debt service coverage ratio, which is the rent divided by the loan payment. A HELOC is a home equity line of credit: you borrow against your equity, repay, and borrow again within limits. The CFPB describes a HELOC as an open-end revolving line you can draw on repeatedly.
This version is built for investors. It records as a standalone second lien behind the first mortgage you keep. If the rental has no mortgage, it can be a standalone first lien. It is never a third lien, never closed together with a purchase, and never a line on your own home or a second home.
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. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. You provide no traditional personal-income documentation, W-2s or personal income calculation. Your LLC can stay on title (subject to lender program eligibility), the members sign as guarantors, and the borrowers on the line need not match the borrowers on the first mortgage.
For the broader picture of how these investor loans work, see Lendmire’s complete DSCR loans guide.
Why a Low First Mortgage Points to a Second Lien
A cash-out refinance replaces your first loan. You lose the rate, the term and the payment you already have. A second lien adds a separate loan behind it, so the first note keeps running exactly as written.
HousingWire reported on the same logic in an interview with a non-QM executive: investors who hold a low-rate first lien often want to keep it and take cash out through a DSCR second instead. The owner with a cheap first loan has a real reason to avoid a refinance.
Here is the part that trips people up. A cheap first mortgage protects your cost, not your capacity. The lender only looks at the balance you still owe. Two owners with the same balance get the same room, whether one pays a low rate and the other a high one.
Lendmire’s piece Top HELOC Providers for Homeowners Locked Into a Low First Mortgage covers the owner-occupied side of this question.
How Underwriting Treats the Line, Step by Step
Each step below is a ceiling or a floor, not an offer. Every file is underwritten individually.
Step 1: Pick the collateral and lien position. The rental must be non-owner-occupied. Eligible types include single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres. A two-to-four-unit property may have at most one vacant unit.
Step 2: Value the property. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report. A full interior appraisal is also an option there. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted.
Step 3: Measure combined leverage. Combined loan-to-value, or CLTV, is your first-mortgage balance plus the full new line, divided by the property’s value. On a second lien, the ceiling is 70% CLTV at a 720 credit score or better, on lines from $50,000 up to $500,000. A low first balance leaves more headroom. That is why the owner who bought years ago, or who has paid the first down, is the natural candidate. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Step 4: Run 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. The minimum is 1.10x. The qualifying payment is a fully amortizing payment of principal and interest on the entire credit limit, calculated at a stress rate set above the start rate. Taxes and insurance are not part of that payment. A lease in place is required.
Step 5: Review credit. A second lien needs a 720 score or better. The lender reviews its own credit report. Mortgage history shows no 30-day late in the last 12 months. Bankruptcy, foreclosure, short sale or deed-in-lieu needs 48 months behind you. No reserves and no cash to close are required, and a borrower can carry at most 5 loans or $2,500,000 with the program.
Step 6: Close and start the draw period. Title work follows: a full title policy on second liens above $400,000, and an owner-and-encumbrance report on smaller second liens. Hazard insurance covers both liens, with flood coverage where required.
One detail needs confirming on your file: how the lender treats the first-mortgage payment on a second lien. The lender’s own coverage calculation governs, and the arithmetic here is illustrative.
How the Line Works After Closing
The line has a 5-year interest-only draw period, then a 25-year fully amortizing repayment period, for a 30-year maturity. The rate is variable.
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 line you open and leave idle for emergencies, so size it to money you will put to work.
The CFPB notes that HELOCs involve variable rather than fixed rates, and the payment moves with the balance and the rate. A coverage ratio that clears at closing can tighten later. Plan for the step from interest-only to full amortization at year six, when the payment on the drawn balance rises.
Key Terms Defined
Second lien: a loan recorded behind your first mortgage that gets repaid second if the property is sold or foreclosed.
CLTV (combined loan-to-value): your first-mortgage balance plus the new line, divided by the property’s value.
Stress payment: the payment the lender uses to test coverage, calculated on the entire credit limit at a higher-than-start rate.
Draw period: the stretch when you can borrow from the line and pay only interest on what you drew.
Seasoning: the waiting period a lender requires after you buy or refinance a property.
Guarantor: an LLC member who signs personally to back the line.
Where the General Rule Breaks
The “keep your first and add a second” plan fails in a few specific places.
Your credit is below 720 and you keep a first mortgage. The second-lien tier starts at 720, with no cell below it. The 700-to-719 range matters only for a first lien on a rental with no mortgage, where 700 to 739 reaches 70% LTV. A borrower who still carries a first mortgage can only take a second lien. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The first balance already eats the ceiling. If the first mortgage plus the line would push past 70% CLTV, there is no meaningful second. Other paths, such as a cash-out refinance, may fit better.
You need one big sum. A line suits staged use. A single large need can point toward a cash-out refinance, which also carries the usual tradeoff of replacing your first note.
The property is outside the lane. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use are not eligible. Neither is a property listed for sale in the prior two months or one with a solar lien. A declining-market flag lowers the ceiling 5 points, and Philadelphia lines carry a ceiling 10 points lower.
The owner is the wrong borrower type. U.S. citizens, permanent residents and non-permanent residents with a Social Security number can use it. Foreign nationals and ITIN borrowers cannot.
A consumer HELOC on a rental. A bank HELOC written for an owner-occupied home is a different product. Renting out your home may be prohibited under a consumer line’s terms. A purpose-built investor line avoids that problem.
Seasoning: Two Six-Month Clocks
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).
What Your Low First Mortgage Does and Doesn’t Protect
| Item | Kept or not |
|---|---|
| Your first-loan rate | Kept |
| Your first-loan term and payment | Kept |
| Extra borrowing capacity | Not added |
| Your risk exposure | Not reduced |
| Easy future refinance of the first | Not guaranteed |
Two liens now sit on one property. If you fall behind, the CFPB warns you could lose the home, and with a second lien that risk covers both loans. Keeping the first protects the rate. It does not protect the position.
Check two things before you apply. First, read your first-mortgage note for any clause on junior liens. Second, think about a later refinance of the first. A new first lender may ask where the line holder will sit, so a future refinance is not automatic. Confirm that point with your lender before you rely on it.
A Worked Sizing Example
Run the numbers on a rental valued at $400,000. This is a modeled assumption, not a market figure.
At the 70% CLTV ceiling, your first balance plus the new line cannot exceed 70% of value. Take the value, multiply by 0.70, then subtract what you still owe on the first. That gap is the maximum line, up to the program’s $500,000 cap and subject to a $50,000 minimum.
If your first balance is low relative to value, the gap is wide. If it sits near 70% of value, the gap closes to nothing. The rate on the first loan never enters this math.
Now the coverage side. Say rent comes in near 1.4x the qualifying payment on a modest line. That clears the 1.10x minimum with room to spare. Size the same property to the maximum line and the stress payment on the full limit grows, because at least 80% of the line is drawn at closing and the test runs on the whole limit. Coverage can fall below 1.10x at that size. A smaller limit can solve a coverage problem.
Choosing Among Structures
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank HELOC on personal income |
|---|---|---|---|
| First mortgage | Kept in place | Paid off and replaced | Kept in place |
| Reviewed on | Rental income | Rental income | Your personal income |
| Payment type | Variable, interest-only draw | Closed-end loan | Variable |
| LLC on title | Allowed, per program | Allowed, per program | Often limited |
| Best fit | Staged capital, low first rate | Large one-time need | Owner with strong income |
Bank HELOC terms vary by that lender, and the figures here describe the DSCR line only.
Situation to Structure
- Low first rate, rent covers the stress payment, credit 720 or better: a second-lien DSCR HELOC.
- No mortgage on the rental, credit 700 or better: a first-lien line, up to 75% LTV at 740 or better and 70% from 700 to 739 on lines to $500,000.
- Lines above $500,000 on a first lien: capped at 65% LTV, up to $1,000,000.
- First balance already near the ceiling: look at other structures, or wait.
- Rental bought or refinanced recently: wait out the seasoning clocks.
- You want money for a purchase down payment: the line can supply the cash, but it cannot be secured by the property you are buying, and it is never closed together with a purchase. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Judging a Program: A Short Scorecard
The best program for your situation is the one that fits these seven points:
1. Lien position. Second lien behind your first, or first lien on a free-and-clear rental.
2. Leverage ceiling. Check the CLTV or LTV against your balance and credit tier.
3. Coverage test basis. Know whether it runs on the full limit and what the minimum is.
4. Title and LLC. Confirm your entity can hold title and who signs as guarantor.
5. Property eligibility. Rule out the excluded types before you spend time.
6. Draw and repayment structure. Confirm the closing draw, minimum later draws and the step to amortization.
7. Valuation path. An automated valuation for smaller lines, a full appraisal for larger ones.
A broker who shops several wholesale DSCR HELOC lenders can match your property and credit to the program that fits. That is the main advantage over walking into a single lender. 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.
Mistakes That Cost Owners
Many owners size the line to the maximum when a smaller limit would clear coverage. Some skip the first-mortgage note review. Others forget the payment steps up when the draw period ends. And “qualified on rent” does not mean undocumented: the lease, the credit report, title, insurance and valuation are all part of the file.
Frequently Asked Questions
Do I have to refinance my first mortgage to get this line?
No. The line records as a standalone second lien behind the first mortgage you keep, so its rate, term and payment stay as they are. Lendmire arranges the line through wholesale lenders, subject to underwriting.
Does a lower first-mortgage rate raise how much I can borrow?
No. Room comes from your balance, your property value and the 70% combined ceiling on a second lien. A low rate keeps your cost down but does not add capacity.
Can my LLC stay on title?
Yes, subject to lender program eligibility. The line allows vesting in your LLC on an investment property. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
What if my coverage comes in below 1.10x?
A smaller credit limit lowers the stress payment, since the test runs on the whole limit. A stronger lease backed by three months of receipts can also help when it exceeds market rent. If neither works, a different structure may fit better.
How soon after buying can I open the line?
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).
