The Quick Read: It depends on your equity: the line equals the rental’s value times the program’s leverage ceiling, minus every lien already recorded, up to a $500,000 cap on a second lien, and the rent only has to clear a 1.10x coverage test to qualify, subject to lender guidelines and underwriting.
- Second lien (you keep your first mortgage): combined loan-to-value up to 70% at a 720 credit score or better, on lines from $50,000 to $500,000.
- First lien (a rental with no mortgage): loan-to-value up to 75% at 740 or better and 70% from 700 to 739 on lines to $500,000. Lines above $500,000, up to $1,000,000, top out at 65% at 720 or better.
- Rent qualifies you; it does not size the line. Value, leverage tier, existing liens and the dollar cap set the amount.
- The full line counts toward leverage, not just the part you draw, and at least 80% of it is drawn at closing.
- All figures are ceilings available through select programs, subject to underwriding. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
How Is the Maximum Line Calculated?
The maximum line is a subtraction problem. Multiply the rental’s value by the leverage ceiling for your lien position and credit tier. Then subtract every lien already on the property. What remains is your room, and the program’s dollar cap can shrink it further.
Two lien positions exist on this program, and they use different labels. A second lien sits behind a first mortgage you keep, and its leverage is combined loan-to-value (CLTV): the first mortgage balance plus the new line, divided by value. A first lien exists only on a rental with no mortgage, and its leverage is plain loan-to-value (LTV). A borrower who keeps a first mortgage can only take the second lien, and that needs a 720 score.
Here is how the room shrinks on a second lien at the 70% CLTV ceiling. The table expresses the first mortgage as a share of value, so the math holds for any property.
| First mortgage (% of value) | Room under 70% CLTV | What it means |
|---|---|---|
| 40% | 30% of value | Healthy room |
| 55% | 15% of value | Moderate room |
| 65% | 5% of value | Likely below the line minimum |
| 70% or more | None | No second lien |
Notice the 65% row. Room equal to 5% of value only works if that slice reaches the $50,000 minimum line, which takes a very expensive rental. On most properties it will not.
The dollar cap works from the other direction. A second lien tops out at $500,000, so a high-value rental with a small first mortgage can have percentage room above the cap. The cap binds first in that case, and anyone needing more usually looks at a DSCR cash-out refinance instead. The same logic applies to a paid-off rental. Free and clear does not mean unlimited: the first-lien tiers and the line ceilings still apply.
Across the wholesale network Lendmire places these files with, a higher credit score does not stretch a second lien past 70%. A 720 and a 780 reach the same ceiling. On a first lien, score does matter, since 740 or better earns 75% while 700 to 739 earns 70%.
What Shrinks the Line
Several factors cut the amount below the headline ceiling.
- A declining-market flag on the property’s area lowers the ceiling by 5 points.
- Credit tier. A second lien has no cell below 720. A first lien has none below 700.
- Lien position. Every dollar of existing mortgage comes straight off your room.
- Line size on a first lien. Crossing $500,000 drops the ceiling to 65%.
- Per-borrower exposure. The program allows at most 5 loans or $2,500,000 per borrower.
- Rent coverage. If the rent fails the 1.10x test at the full line, a smaller line may pass.
That last point deserves a second look. The coverage test uses a fully amortizing, stress-tested payment on the entire credit limit, not on what you plan to draw. Because the payment scales with the limit, asking for a smaller line lifts the coverage ratio. The coverage test uses principal and interest only; taxes and insurance are not part of the qualifying payment. Confirm on the file how the lender treats the first-mortgage payment on a second lien, because the lender’s own calculation governs.
Key Terms Defined
DSCR (debt service coverage ratio): the rental’s monthly rent divided by the payment the lender tests, so 1.10x means rent covers that payment with a 10% cushion.
CLTV (combined loan-to-value): your first mortgage balance plus the full new line, divided by the property’s value.
Second lien: a loan recorded behind your first mortgage, which stays in place.
Draw period: the first 5 years on this program, when you can borrow from the line and pay interest only on the drawn balance.
Stress payment: the fully amortizing payment the lender uses to test coverage on the entire limit, set above the starting rate to build in a cushion.
Seasoning: the waiting period a lender requires between buying or refinancing a property and opening a new loan on it.
Who Qualifies, and What the File Needs
Think of this as a line on a rental you keep. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That means no traditional personal-income documentation, W-2s, pay stubs or personal debt-to-income calculation. DSCR products 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. A line on your own home or a second home is a different product.
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 can have at most one vacant unit.
Title is more flexible than on many alternatives. The rental can stay in your LLC, subject to lender program eligibility. The LLC’s members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment. The borrowers on the line also do not have to match the borrowers on your first mortgage.
The credit file is plain:
- A 720 score for a second lien, or 700 for a first lien.
- No 30-day mortgage late in the last 12 months.
- 48 months since any bankruptcy, foreclosure, short sale or deed-in-lieu.
- No reserves and no cash to close.
Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
On valuation, lines up to $400,000 use an automated valuation with a property inspection report, or you can choose a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted.
The property types that fit are single-family homes, PUDs, townhomes, two-to-four-unit buildings, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use buildings, modular and log homes, and a property with a solar lien are outside the program. So is a rental listed for sale in the prior 2 months. NerdWallet’s explainer on HELOCs for investment property adds that some lenders in the broader market also restrict lines by location or by whether the home rents year-round, so short-term rentals deserve a direct question. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Seasoning is the last gate. 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).
Lendmire is the broker. The loan is arranged through a wholesale lender, which reviews and approves each file individually.
Ways to Invest the Funds, Compared
The line amount is only half the decision. The other half is where the money goes. The same draw behaves very differently depending on its destination.
| Use of funds | Payment profile | Main risk | Best fit |
|---|---|---|---|
| Down payment on another rental | Two debts to carry | No equity in the new property | Strong rent on both properties |
| Rehab on the secured rental | Interest-only at first | Overruns, delays | Clear scope and value plan |
| Business or other investment | Repaid from other cash flow | Rental carries a debt it did not create | Steady outside income |
| Standby reserves | Interest on the drawn balance | 80% is drawn at closing | Poor fit on this program |
Rental down payment. It also stacks debt. If the line funds the whole down payment, you hold no equity in the new property, and that rental has to cover its own mortgage plus the line’s payment. A modest coverage ratio on the new deal leaves little room for a vacancy.
Rehab. Money spent improving the rental that secures the line can raise the rent. It may also support a higher appraised value, depending on comps and underwriter review. Neither is automatic, so a plan with a defined scope beats a loose budget.
Reserves. Because at least 80% of the line is drawn at closing, this program does not work as an unused safety net. Interest accrues on most of the balance from day one. An owner who wants standby cash should size a smaller line or look elsewhere.
Paying down other debt. This only helps if the line’s cost and terms beat the debt it replaces. Remember that the line is variable-rate, so the comparison can shift after closing.
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.
DSCR HELOC, Cash-Out, or a Personal-Income Line?
The right tool depends on what happens to your first mortgage. If your existing mortgage is one you want to keep, a second lien lets you leave it untouched. If you would rather replace it, a cash-out refinance does that. The structural differences look like this:
| Factor | DSCR HELOC | DSCR cash-out refinance | Personal-income investment line |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Qualified on | Rent coverage | Rent coverage | Personal income, credit |
| Title | LLC allowed, per program | Per that program | Individual or revocable trust |
| Size limit | $500,000 on a second lien | Per that program | Lines up to $500,000, DTI 50% max |
The last column describes the personal-income line’s own rules, not this program’s. If your title sits in an LLC, that line is not an option without a vesting change.
Another route is to compare a HELOC against a cash-out refinance on a rental. It matters most when your first mortgage balance is low enough that replacing it would cost you more than the line adds. A line that fits inside the leverage room generally avoids touching that mortgage at all.
The federal consumer regulator explains how a HELOC differs from a home equity loan: a home equity loan pays out a lump sum, while a line is revolving and usually adjustable. Both are second mortgages if you already have a first.
What Happens When Repayment Starts
The payment steps up when the draw period ends. For 5 years you pay interest only on the drawn balance. Then a 25-year fully amortizing repayment period begins, with a 30-year maturity overall. Principal enters the payment at that point, and because the rate is variable, the payment can also move with the market.
Run the logic without dollars. Say your rent covered the interest-only payment with a comfortable cushion. Once amortization begins, the same rent faces a larger payment, so your coverage ratio compresses. The lender’s coverage test already uses a fully amortizing payment on the whole limit, which is a useful preview of that later stage. If a file barely clears 1.10x at the full line, expect thin coverage when repayment starts. Rent growth or a lower balance can offset it.
The federal consumer regulator’s overview of HELOCs describes the line as a revolving credit with a draw period followed by repayment. This program’s terms are the ones above, not generic market terms.
When Not to Borrow the Maximum
Borrowing less than the ceiling is often the sounder choice. Several risks argue for it.
- Your property secures the debt. If the rental struggles, both liens are exposed.
- The rate is variable. Your cost can rise after closing.
- Lines can change. The federal regulator’s HELOC brochure notes that lenders can freeze or reduce a line if home value falls. It also says you generally must pay off the line in full if you sell.
- Stacked debt. A purchase funded entirely by borrowed money leaves no cushion.
- Thin equity. A line that uses nearly all of your CLTV room leaves no flexibility if values slip.
A short decision checklist helps:
1. Set the goal first: down payment, rehab, business or debt payoff.
2. Check the rental’s coverage at a smaller limit as well as the maximum.
3. Confirm that the new property, if any, covers its own debt plus the line.
4. Confirm title, state, property type and the two seasoning clocks before you spend time on the numbers.
Frequently Asked Questions
Can I use this line if my rental is in an LLC?
Yes, subject to lender program eligibility. The LLC can remain on title, its members sign as guarantors, and a title holder who is not a borrower signs the non-borrowing owner acknowledgment. The property must be a non-owner-occupied investment rental. A standard personal-income investment line, by contrast, requires title in an individual’s name or a revocable living trust.
How soon after buying a rental can I open a 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). A rental listed for sale in the prior 2 months is also outside the program. Plan the line around your purchase or refinance date rather than the other way around.
Do I have to draw the whole line?
You must draw at least 80% of the line at closing, and the closing draw is never below $50,000. On the smallest lines, that means the full line is drawn at closing. After closing, each later draw must be at least $5,000, and interest-only payments apply to the drawn balance during the 5-year draw period. Size the limit to a real plan, since the unused portion is small.
What if I need more than $500,000?
A second lien tops out at $500,000. A first lien on a rental with no mortgage can reach $1,000,000, but lines above $500,000 carry a 65% LTV ceiling at 720 or better. For larger needs, many owners compare a DSCR cash-out refinance. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Is this available in every state?
No. It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Property type matters too: rural-designated property, condotels, row homes and leaseholds are excluded. Per-borrower exposure is capped at 5 loans or $2,500,000. Eligibility is confirmed on each file.
