The Quick Read: A second-position home equity line leaves your current first mortgage’s balance, payment, and terms alone. On an investment property, the line reaches up to 70% combined loan-to-value (CLTV, the first loan plus the new line divided by the property’s value) and a $500,000 line size, with a 700 credit score floor. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
- The best program for your situation depends on how the property is titled, your credit profile, how much first-mortgage debt already sits on it, and how much cash you actually need.
- Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment, and at least 75% of the line is drawn at closing.
- The individual borrower or a revocable living trust must hold title. An LLC cannot, so a property deeded to an LLC usually points to a different tool.
- Lines of this size ordinarily run on an automated valuation, so a traditional appraisal is commonly not needed.
- The first mortgage stays untouched, but a later refinance of it has to account for the new lien behind it.

How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
What Does “Without Disturbing the First Mortgage” Actually Mean?
It means the new loan does not replace the old one. Your first mortgage keeps its balance, its payment, and its terms. When a mortgage already exists, the new line is a separate loan recorded as a junior lien, and you make a separate payment on it.
A cash-out refinance works the opposite way. It pays off the first mortgage and replaces it with a larger one, so every dollar you owe is repriced. An equity line adds debt on top of the existing debt and leaves the original loan where it was.
Investors choose this structure for one main reason. A first mortgage taken at favorable terms is worth keeping, and a second lien lets you tap equity without giving it up. The tradeoff is that you now carry two liens and two payments on one property.
Position matters here. The network’s investment line can sit in first or second lien position. If the property has no mortgage, the line can be the only lien. If a mortgage exists, the line goes behind it.
How Underwriting Treats an Investment Line, Step by Step
Underwriters look at a handful of things, and they look at them in a predictable order. Walk through them before you apply.
Step 1: Title. Ownership is the first test, and it is the sharpest structural difference from a DSCR loan, which is built for business-purpose investor ownership. An equity line requires the individual borrower or a revocable living trust to hold title. A property already in an LLC needs a vesting change first, or a different product.
Step 2: Credit. Investment lines require a minimum 700 credit profile. A 720 score and a 700 score both reach the same 70% CLTV ceiling, so a higher score buys eligibility rather than extra leverage. The lender uses a single-bureau score keyed to the primary wage earner. The report must be no more than 90 days old at closing, and rescoring is not available.
Step 3: Debt-to-income. The maximum DTI is 50%. The lender tests it on the interest-only payment calculated at the maximum draw, not on what you plan to use. If you size the line larger than you need, your debt ratio still carries the full amount.
Step 4: Combined leverage. The lender adds the first mortgage, any other lien, and the new line. It divides that total by the property value. On an investment property, the result cannot exceed 70% CLTV.
Step 5: Valuation. A line of $500,000 or less ordinarily runs on an automated valuation with no traditional appraisal. A higher CLTV may trigger a secondary valuation. You can also request a full appraisal in any case, and it makes sense when you have recently renovated, because an automated value may not reflect the work.
Step 6: Property type. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Step 7: Credit history and exposure. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4. A borrower can hold no more than three lines at once, and an investor with more than 15 financed properties is not eligible.
Notice what is missing from this list: the rent. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. An equity line qualifies the borrower. That difference decides which tool fits which investor.
How Big Can the Line Be?
The line runs from $25,000 up to a $500,000 maximum on an investment property. In practice, the 70% CLTV ceiling binds first on most properties. The formula is simple: take 70% of the property value, then subtract everything already owed against it.
Run the percentages on a rental with a first mortgage at 45% of its value. The ceiling leaves 25 points of value for the new line. If the first mortgage sits at 60% of value, only 10 points remain. If it sits at 70% or higher, nothing remains, and the structure does not work.
That last case catches people. Equity and room are different things. A property can show real equity and still leave little room under the combined ceiling, because the ceiling counts the first mortgage in full.
Two practical points follow. First, plan against the full line limit rather than the amount you expect to draw, because debt ratios use the maximum draw. Second, the $500,000 cap only matters on higher-value properties. On most rentals, the CLTV math runs out before the dollar cap does.
How the Draw and Repayment Periods Work
The CFPB describes a HELOC as an open-end line you can borrow against repeatedly, with a draw period followed by a repayment period. Draw periods on consumer lines can last about 10 years, and some plans require a minimum draw or outstanding balance.
Investment lines through Lendmire’s network follow a tighter structure. The draw period is 5 years, with interest-only payments. Repayment then runs 25 years, fully amortizing. Pricing floats through both periods and never converts to a fixed structure.
At least 75% of the line is drawn at closing. That detail changes how the product behaves. The FTC notes that HELOC borrowers typically pay only on the amount drawn, not the full limit. On an investment line with most of the balance drawn up front, you carry nearly the full cost from day one. Treat it as a mostly funded second loan with a small revolving sliver, not as a standby reserve you can leave untouched.
The FTC also points out that borrowers should expect charges to open, use, and maintain a line, plus third-party costs such as credit reports and attorney fees. Ask for the full cost list before you commit.
Where the General Rule Breaks
The idea that the first mortgage stays untouched holds up in the plainest sense. These edge cases are where it gets complicated.
A later refinance of the first. This is the easiest catch to overlook. With a junior lien in place, refinancing the first mortgage typically requires the line’s lender to agree to stay behind the new loan. That is general lien mechanics, not a rule specific to any one lender. Plan for it before you open the line, especially if you expect to refinance the first mortgage later.
LLC-held rentals. Investors who hold rentals in an LLC often assume the line follows the same structure as their other loans. It does not on this network, because the line requires individual or living-trust title. Moving a property out of an LLC can create its own problems, so check the first mortgage’s terms and your insurance before you change anything.
The first mortgage’s own terms. Read your existing note for clauses that restrict additional liens or trigger on a transfer of title. A restrictive clause can turn a clean second lien into a default risk on the first loan.
Other liens. Any existing line, junior mortgage, or tax lien counts against the same CLTV budget. A property with an older line already in place may have no room left.
Property listed for sale. In several states, a property listed for sale, or listed within the past 60 days, is ineligible.
Availability. Lendmire places these lines in 16 full-service states only. That is narrower than its 41-market DSCR footprint, which includes Washington, D.C.
Portfolio size. The three-line limit and the 15-financed-property limit can stop a larger portfolio even when each property has plenty of equity.
Ineligible properties. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered. This is a categorical exclusion, not a pricing issue.
Equity Line or DSCR Cash-Out: How to Choose
An equity line and a DSCR cash-out refinance solve the same need in opposite ways. One keeps the first mortgage. The other replaces it. This table shows the structural differences.
| Factor | Equity line (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Paid off and replaced |
| Title | Individual or living trust | LLC possible |
| Leverage ceiling | 70% CLTV on investment | About 75% LTV, 70% on STR |
| What is tested | Borrower credit and DTI | Rent against the payment |
| Seasoning | Per lender file review | About 6 months is common |
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. They also accept LLC ownership, subject to lender program eligibility.
The ceilings above are not interchangeable. The 75% figure applies to a standard rental cash-out. A short-term-rental cash-out tops out at 70%. The equity line’s 70% is a combined figure that includes the first mortgage.
Here is how the choice usually breaks down. Keep the first mortgage and add a line when the first loan is worth preserving, the property is in your own name or a living trust, and your credit and debt ratios are strong. Move to a DSCR cash-out when the property sits in an LLC, when your personal debt ratios are stretched, or when the property’s rent is the strongest part of the file.
Coverage matters on the DSCR side. DSCR compares rent to the full monthly obligation of principal, interest, taxes, insurance, and any association dues. Select programs start at 1.00. A separate select-lender path goes below 1.00, with leverage and terms adjusted. A DSCR near 1.00 does not mean positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
For the full picture of how those loans work, see the complete DSCR loans guide.
When does keeping the first stop helping? It stops when the first loan’s cost is no better than a refinance would deliver, or when the combined leverage leaves too thin a cushion on the rent. In both cases, the main reason to leave the first alone has faded.
How Do You Find the Best Program for Your Situation?
The best program for your situation depends on the file, not on a ranking. A broker that works with several wholesale lenders can compare how each one treats the same property, and that comparison is where a broker adds value.
- Title: Is the property in your name or a living trust today? If not, what would a vesting change involve?
- Credit: Do you clear the 700 floor on a single-bureau score, with a report no more than 90 days old?
- Combined leverage: After the first mortgage and any other liens, how many points of value are left under 70%?
- Debt ratio: Does your DTI hold at 50% or below when the payment is calculated on the full line?
- Property type: Is it single-family, 2-4 units, a PUD, a townhome, or a condo? Or is it a type that is not offered?
- Use of funds: Do you need most of the money at once, or are you planning repeated draws?
- Exposure: Do you already hold other lines, or own many financed properties?
Different wholesale lenders weigh these items differently, and some overlays are stricter than others. On this network, an investment line has a 700 credit floor and a 70% CLTV ceiling. Where programs differ is in tradeoffs such as tradeline and housing-history standards, foreclosure treatment, and property restrictions. A broker’s job is to match the file to the program where it fits cleanly.
If the property clears every item above, an equity line is a clean fit. If it fails on title, credit, or leverage, the checklist has just told you why a DSCR cash-out deserves a look.
What to Prepare Before You Apply
Gather the following before you start, so you can answer the checklist honestly:
- Your current first mortgage statement, plus the note itself, so you can read the lien and transfer clauses.
- The property’s vesting documents, to confirm how title is held.
- A list of every lien and line already recorded against the property.
- A current credit report, and awareness of who counts as the primary wage earner.
- Your debt obligations across all financed properties, since housing history is reviewed across every financed property.
- A repayment plan that survives the end of the interest-only draw period.
That last item matters more than any other. When the draw period ends, the payment changes from interest-only to fully amortizing. Stress-test that step before you sign, using the combined payments on both liens and the property’s rental coverage.
Who Should Skip It
Skip the equity line if the property sits in an LLC and you do not want to move it. Skip it if your first mortgage already uses most of the 70% ceiling. Skip it if you expect to refinance the first mortgage soon, since the junior lien complicates that step. Skip it if you need a large sum for a purchase and have not planned how you will repay it.
Remember also that the line only supplies cash. Your next purchase still needs a down payment source, a loan, or an all-cash closing. The line funds part of that plan, not all of it.
Key Terms Defined
CLTV (combined loan-to-value): The first mortgage plus any other liens and the new line, divided by the property’s value.
Second lien (junior lien): A loan recorded behind the first mortgage, repaid after the first if the property is sold or foreclosed.
Draw period: The stretch of time when you can borrow against the line, here 5 years with interest-only payments.
Due-on-sale clause: A term in some mortgage notes that lets the lender demand payoff if title transfers or certain liens are added.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly obligation, covering principal, interest, taxes, insurance, and any association dues.
Vesting: The legal form in which title to the property is held, such as an individual, a trust, or an LLC.
Frequently Asked Questions
Can I get an investment property HELOC if the rental is held in an LLC?
Not directly. Title must be held by the individual borrower or a revocable living trust, and an LLC cannot hold it. A property deeded to an LLC needs a vesting change, or a DSCR cash-out refinance, which accepts LLC ownership subject to lender program eligibility.
Does the first mortgage really stay exactly as it is?
Yes, its balance, payment, and terms do not change when you add a second-position line. The catch comes later. Refinancing the first mortgage with a junior lien in place typically requires the line’s lender to stay behind the new loan.
How much can I borrow against a rental?
Up to 70% combined loan-to-value on an investment property, capped at a $500,000 line. Subtract your first mortgage and any other liens from 70% of the value to see what is left. Lines above $500,000 are available only on primary residences.
Will the lender order an appraisal?
Usually not a traditional one. Lines of $500,000 or less ordinarily run on an automated valuation, though a higher CLTV may require a secondary valuation. You can request a full appraisal in any case, which helps after a recent renovation.
Is the interest tax-deductible?
It depends on the use of funds and the way you hold the property. 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.
