The Quick Read: The most you can borrow on a second lien comes from the lowest of three limits: the combined loan-to-value room left after your first mortgage, the program’s dollar cap, and the rent-based coverage test on the full line. Which lenders fit depends on your file. A broker shops several wholesale programs and matches the property to the one that fits.
- Second lien: combined loan-to-value (CLTV) up to 70% at a 720 credit score or better, on lines from $50,000 to $500,000, through select programs and subject to underwriting. A second lien is never written above $500,000.
- First lien on a rental with no mortgage: loan-to-value (LTV) up to 75% at 740 or better on lines to $500,000. Only first-lien lines above $500,000 run to $1,000,000, with a 65% LTV ceiling.
- Coverage test: rent must cover the stress payment on the entire line at 1.10x or better.
- Footprint: offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
- Figures are ceilings, not offers. Every file is underwritten individually. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Key Terms Defined
Second lien is a loan recorded behind your first mortgage. If the property is sold or foreclosed, the first mortgage is paid before the second.
HELOC is a home equity line of credit. It is a revolving line you draw against, secured by the equity in a property.
Equity is the property’s value minus what you owe on it.
CLTV is combined loan-to-value. You add the first mortgage balance and the new line, then divide by the property’s value.
DSCR is debt-service coverage ratio. It is the rental’s gross monthly rent divided by the qualifying payment.
Closed-end second is a one-time lump-sum loan behind the first mortgage. It is not a revolving line.
Draw period is the stretch when you can borrow from the line. Repayment period is the stretch after it, when the balance is paid down.
What Is a DSCR HELOC, and Is It a Second Mortgage?
Usually, yes. In the Lendmire network, a DSCR HELOC is a revolving line on a rental you keep. It is written as a standalone second lien behind your existing first mortgage. It can also be a standalone first lien on a rental with no mortgage.
The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s, pay stubs or debt-to-income calculations. The rent, the lease, the credit report and the valuation are all documented.
Four boundaries are worth knowing up front:
- 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 one-to-four-unit non-owner-occupied rentals only.
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.
You keep your first mortgage in place. That is the main reason investors choose a line over a cash-out refinance. You reach the equity without replacing the loan you already have. The borrowers on the line do not have to be the borrowers on the first mortgage. Vesting in your LLC is allowed, subject to lender program eligibility. The members sign as guarantors.
Banks offer a different product, a HELOC qualified on personal income and debt-to-income ratio. NerdWallet notes that investment-property lines come from a smaller pool of lenders, with stricter requirements and smaller borrowing amounts than a primary home. Some lenders also ask for multiple appraisals or restrict by location. A rent-qualified line avoids the personal-income file, but it has its own rules, covered below.
How the Maximum Gets Set, Step by Step
No federal agency sets a combined-leverage ceiling for investment-property second liens. Each program’s guidelines do. Across Lendmire’s wholesale network, the maximum on a second lien comes from three limits, and a fourth rule then governs how much of the line is drawn at closing.
Step 1: Find the CLTV room. Multiply the property’s value by the CLTV cap. On a second lien, that cap is 70% at a 720 score or better. Then subtract the first mortgage balance. What remains is the most the line could be on leverage alone.
Step 2: Apply the dollar limits. Second-lien lines run from $50,000 to $500,000. If your room is below $50,000, there is no line. If it is above $500,000, the cap binds.
Step 3: Run the coverage test. The lender divides gross monthly rent by a qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit at the start rate plus 2 percentage points. Taxes and insurance are not part of the qualifying payment. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The result must be at least 1.10x.
Confirm on the file how the lender treats the first-mortgage payment in a second-lien coverage calculation. The lender’s own calculation governs. The test uses the whole limit, not just the drawn balance, so a bigger line makes the test harder to pass.
Step 4: Apply the draw rule. 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.
Your maximum is the lowest result of the first three steps. Step four then shapes how much of it you take on day one.
On a first lien, the logic is the same without a first mortgage to subtract. LTV runs up to 75% at 740 or better and 70% from 700 to 739, on lines to $500,000. Lines above $500,000 run to $1,000,000 and carry a 65% LTV ceiling at 720 or better. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Four Scenarios, Expressed as Percentages of Value
Dollar results depend on your property, so these scenarios use percentages of value. All four assume a 720 score on a second lien, where the cap is 70% CLTV. Figures are illustrative, and the lender’s calculation governs.
| Scenario | First mortgage | What binds | Result |
|---|---|---|---|
| Low first mortgage | 20% of value | $500,000 cap or coverage | Room is 50% of value |
| Middle of the road | 40% of value | CLTV room | Room is 30% of value |
| Heavy first mortgage | 65% of value | Minimum line size | Room is 5% of value; may fall under $50,000 |
| Strong equity, thin rent | 25% of value | Coverage test | Line shrinks until rent clears 1.10x |
The first row is where the dollar cap shows up. On a property worth well over a million dollars, 50% of value exceeds $500,000, so the cap binds before leverage does.
The third row is the quiet failure. The room exists on paper, but it is smaller than the smallest line the program writes. A low first-mortgage balance leaves the most room, so the balance matters more than the property’s headline value.
The fourth row is the one investors miss. Equity does not pay the line. Rent does. If rent covers the stress payment on a requested line at, say, 1.05x, the request has to shrink or the rent evidence has to improve.
Where the General Rule Breaks
The formula above assumes a clean file. These edge cases change the answer.
Credit sets the ceiling. A second lien needs a 720 score. Below 720, there is no second-lien tier. A first lien starts at 700. Mortgage history must show no 30-day late in the last 12 months. It also requires 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
Seasoning has two 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).
Valuation changes with size. Lines to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted.
Property type matters. Eligible properties are single-family homes, planned unit developments, townhomes, two-to-four-unit properties, and warrantable and non-warrantable condominiums. Lots up to 10 acres are also allowed. A two-to-four-unit property may have at most 1 vacant unit, and a lease in place is required. These are outside the lane:
- rural-designated property
- row homes
- condotels
- commercial or agricultural property
- leaseholds and land trusts
- age-restricted communities
- hobby farms
- modular and log homes
- land contracts and mixed-use
- a property listed for sale in the prior 2 months
- a property with a solar lien
Soft markets cost points. A declining-market flag lowers the ceiling by 5 points.
Exposure is capped. The program allows at most 5 loans or $2,500,000 per borrower. Equity in one rental does not support a line on another.
Borrower status counts. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Your first mortgage has a say. Before you apply, check that the first mortgage’s loan documents allow a junior lien. If you also plan a new DSCR first mortgage, think through the order, because a first mortgage is easier to place before a line than behind one.
Line, Cash-Out Refinance or Bank HELOC?
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank investment HELOC |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | Rent | Rent | Personal income, per bank rules |
| Maximum set by | CLTV room and line cap | LTV on the new loan | The bank’s own limits |
| Structure | Revolving line | Lump sum | Revolving line |
The refinance often reaches more equity, because it resets the whole loan against one LTV limit. The line is usually smaller, because the first mortgage eats into the combined limit. The trade is that the line leaves your existing first mortgage alone.
Variable-rate lines also carry payment risk. The CFPB describes a HELOC as open-end credit you can draw on repeatedly. It notes that some plans require an initial draw and that payments often rise significantly once repayment starts. On this program, the draw period is 5 years interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, within a 30-year maturity. The rate is variable.
Which Lenders Fit, and How to Check a Stated Maximum
DSCR HELOC is a market label, not a standard product. Two lenders can use the same name for different structures. Some are revolving, some are closed-end, and some are first-lien only.
Lendmire is a mortgage broker, not a lender. It works with a nationwide network of wholesale DSCR HELOC lenders and compares programs against your file. The choice of lender depends on the property type, credit profile, equity, rent and the leverage you need. The program also changes by lender, so every file is underwritten individually. Ask each lender or broker these questions:
1. Is this a revolving line or a closed-end second?
2. What is the CLTV cap at my credit score, and what is the dollar cap?
3. How does the coverage test work, and does it use the whole limit or the drawn balance?
4. How is the first-mortgage payment treated in a second-lien test?
5. What is the minimum closing draw?
6. Which valuation applies at my line size?
7. Does the program allow LLC vesting and my property type?
8. Does my state sit inside the program’s footprint?
On the last point, Lendmire’s program covers these 15 states: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington. Hazard insurance must cover both liens, with flood coverage where required.
When the Cap Is Too Low
If the line falls short, work out which limit bound first. That tells you what to change.
- Leverage bound: A cash-out refinance may reach more equity, because it replaces the first mortgage and resets the LTV test. The reverse is also true. If the first mortgage is a good one, the line lets you keep it.
- Coverage bound: A smaller line may clear the test where a larger one fails. Stronger rent evidence can also help, such as a lease above market supported by three months of receipts.
- Credit bound: Below 720, a second lien is not offered. A rental with no mortgage can use the first-lien tiers from 700.
- Property bound: If the property type is outside the lane, a different DSCR product may fit.
A line also cannot buy the next rental directly. It needs a property you already own as collateral.
If the bound is the program rather than your numbers, the other path is a different structure. Lendmire’s complete DSCR loans guide walks through the alternatives. Its piece on bank statement HELOC providers and the maximum on a second lien covers a line that is reviewed on documented business income instead of rent.
Frequently Asked Questions
Can my LLC be the borrower on a DSCR HELOC?
Yes, vesting in the owner’s LLC is allowed on this program, for investment property only. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. All of it is subject to underwriting.
Does a DSCR HELOC check my personal income?
No personal income is calculated. The lender still pulls your credit and reviews the lease and the valuation. There is no traditional personal-income documentation: no W-2s or pay stubs.
What if my score is between 700 and 719 and I have a first mortgage?
A second lien needs 720, so there is no second-lien tier at that score. A first lien starts at 700, but it exists only on a rental with no mortgage. Raising the score, or paying off the first mortgage, are the two ways the tiers change.
Do I have to draw the full line at closing?
At least 80% of the line (and never less than $50,000) is drawn at closing. On the smallest lines, that means the whole line. Later draws are at least $5,000 each.
Does the line need reserves?
No reserves and no cash to close are required on this program. Credit, coverage and valuation requirements still apply, and all of it is subject to lender guidelines. Exposure is capped at 5 loans or $2,500,000 per borrower.
