The Quick Read: No honest ranking of providers exists, because which lenders will write a line behind your existing first mortgage on a rental depends on your credit, your equity, what the property is, and how it is titled, so the useful move is learning the screens every provider applies and matching your file to the program that fits.
- On an investment property, the network ceiling is 70% combined loan-to-value, with a 700 credit minimum and a line of up to $500,000.
- The property must be titled in your own name or a revocable living trust. An LLC cannot hold title.
- The line is underwritten on your personal debt-to-income ratio (50% maximum), not on the property’s rent.
- At least 75% of the line is drawn at closing, and pricing floats for the life of the line.
- Lendmire’s network HELOC lending runs in 16 states, which is narrower than its DSCR footprint.
Key Terms Defined
Second lien is a loan recorded behind your first mortgage. If the property is sold or foreclosed, the first lender gets paid before the second.
Combined loan-to-value (CLTV) adds every loan on the property, including the full credit line, and divides by the property’s value.
Draw period is the stretch when you can borrow from the line and pay interest only. A repayment period follows, when the balance amortizes to zero.
Debt-to-income (DTI) is your total monthly debt payments divided by your gross monthly income.
Vesting is how the property’s title is held: in your name, in a trust, or in an entity such as an LLC.
DSCR stands for debt service coverage ratio. It divides a property’s rent by its monthly payment (principal, interest, taxes, insurance, and HOA dues, together called PITIA). A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
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.
Why a Ranked List of Top Providers Doesn’t Hold Up
Lenders that write a line against a rental are scarce, and the list changes. NerdWallet says a HELOC on an investment property is possible but that not every lender offers one. It adds that requirements are strict, that lenders see higher default risk than on a primary home, and that more than one appraisal may be required.
That is why any fixed top-five list ages badly. A lender that writes these lines today can pull the product tomorrow. The provider that is best for one borrower can decline the next one for reasons that have nothing to do with the lender’s quality: the title is in an LLC, the credit score is a few points short, or the borrower already holds too many financed properties.
The better question is which program fits your property, your credit, and your goal. Lendmire is a mortgage broker, not a lender. It works with a network of wholesale HELOC lenders and matches a file to the program whose rules it fits. The best program for your situation depends on the property type, your credit profile, how much combined leverage you need, and how you hold title. The rest of this piece shows what those lenders look for, so you can see where your file lands before anyone pulls credit.
What You’re Actually Borrowing
A HELOC behind your first mortgage is a revolving line secured by the same property. Your first mortgage stays exactly as it is, with the same balance and the same terms. The new line is recorded behind it and borrows only against the equity left over.
That is the appeal for an investor who is happy with the existing first loan. You don’t replace it. You tap the gap between what the property is worth and what the first lender is owed.
On Lendmire’s network these are standalone lines, written in first or second lien position. You don’t need to go back to your first-mortgage servicer. The tradeoff is that the line is a different animal from a DSCR loan. It is a personal-credit product with floating pricing and a draw-then-repay structure, and its underwriting looks at you before it looks at the building.
How Underwriting Treats the Line, Step by Step
Step 1: The lender sizes the line by combined leverage. The maximum line equals the property’s value times the lender’s CLTV ceiling, minus every loan already on the property. The older CFPB home equity booklet lays out the same logic: take a percentage of appraised value, then subtract what you owe. The full line commitment counts, not just the amount you draw on day one.
Here is how that works as percentages. Say your first mortgage sits at 55% of the property’s value and the investment ceiling is 70% CLTV. The most the line can add is 15% of value. If your first mortgage already sits at 68%, there is only 2% of room, and the line may not clear the program’s $25,000 minimum.
Step 2: The lender values the property. On lines at or below $500,000, the network ordinarily runs an automated valuation instead of a traditional appraisal. A higher CLTV can trigger a secondary valuation. You can always request a full appraisal, and a recent rehab may show up better in one. Every investment line on this network falls at or below $500,000, so the automated path is the usual starting point.
Step 3: The lender pulls and scores your credit. The network uses a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not offered. The credit minimum depends on occupancy: 600 on a primary residence, 640 on a second home, and 700 on an investment property.
Step 4: The lender runs your DTI. Maximum DTI is 50%, with 45% for credit profiles from 600 to 679. A ratio above 45% requires at least a 680 score. The payment used is the interest-only payment calculated on the maximum draw, not on what you plan to borrow. Because a line can climb to full draw, a thin DTI can sink a file even when the equity is generous.
Step 5: The lender checks the property and the title. Eligibility depends on the property type and on how you hold title. Both are covered below under edge cases.
Step 6: You document the file. Expect an application, a credit report, income documentation, the first-mortgage statement, insurance, and title work. Exact lists vary by lender, and the lender decides what it needs once it sees the file.
The contrast with DSCR matters most here. A bank-style line leans on your income and your debts. A DSCR loan leans on what the property earns.
The Structures That Exist
Lendmire’s wholesale network has two HELOC programs. The higher-leverage program uses a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The longer-runway program uses a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Investment properties use the 5-year draw and 25-year repayment structure only.
On both programs, at least 75% of the line is drawn at closing. Pricing floats across the draw and the repayment period and never converts to fixed. After closing, the longer-runway program sets a $1,000 minimum for each later draw. The higher-leverage program does not state one. Because most of the line is drawn at closing, this product is not a standby line that sits unused.
The ceilings depend on occupancy, and they differ a lot:
| Occupancy | Max CLTV | Credit needed | Max line |
|---|---|---|---|
| Investment property | 70% | 700 minimum | $500,000 |
| Second home | 90% at 720+ | 640 minimum | $500,000 |
| Primary residence | 90% at 720+ | 600 minimum | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
The 90% ceiling exists only at a 720 or better credit profile, and it is not generally available. On an investment property, 70% CLTV is the top of the matrix. Market surveys may report higher figures for equity lines at lenders. Those describe the broader market, not this network.
A line above $500,000 is for primary residences only. It requires a credit profile of 700 or better (720 on the longer-runway program), caps at 75% CLTV, and requires a full appraisal. Line sizes run from $25,000 to $750,000, depending on the program and the occupancy.
Eligible properties include single-family homes, 2-4 unit buildings, PUDs, townhomes, and condominiums, including non-warrantable condos. Modular factory-built homes are eligible on the longer-runway program only.
Where the General Rule Breaks
Title held in an LLC. Individuals and revocable living trusts can hold title on these lines. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. This is the sharpest structural difference from a DSCR loan, where entity vesting is common, subject to lender program eligibility. If the property is already deeded to an LLC, you need a vesting change before a line becomes possible. Otherwise a DSCR cash-out is the alternative.
Too many properties or too many lines. A borrower can hold up to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible.
Property types that are not offered. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not eligible on either program. A property listed for sale, or listed within the past 60 days, is ineligible in several states.
Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal on both programs. On investment files, a foreclosure needs 7 years and a deed-in-lieu, pre-foreclosure, or short sale needs 4. The higher-leverage program declines foreclosure-family history on primary residences and second homes regardless of age, so a borrower with that history needs the other program.
A line that can shrink. The CFPB’s HELOC booklet says lenders can reduce a line if the home’s value falls. Floating pricing adds a second pressure point. A rental that barely covers the first mortgage can strain once the line’s payment is layered on.
Refinancing the first mortgage later. A second lien in place complicates any later refinance of the first. Both liens must be dealt with on a sale or a refinance. Plan for that before you take the line.
A Line or a DSCR Cash-Out? The Decision in Practice
Both products pull equity from a rental. They solve different problems.
| Factor | Line behind your first | DSCR cash-out refinance |
|---|---|---|
| Your first mortgage | Stays in place | Replaced by the new loan |
| Underwritten on | Your credit and DTI | Property rent vs. payment |
| Title | Individual or revocable trust | LLC possible, per program |
| Investment ceiling | 70% CLTV | About 75% LTV standard |
| Structure | Floating, draw then repay | 30-year fixed is the spine |
On a DSCR cash-out, the ceiling is about 75% LTV on standard rentals and 70% on short-term-rental collateral. About 6 months of seasoning is the common expectation. Figures vary by lender, credit, and property, and all are subject to lender guidelines. NerdWallet also lists a cash-out refinance as the main alternative to a rental HELOC. Lendmire’s piece HELOC vs Home Equity Loan for Borrowing Behind the First Mortgage You Already Have covers the closed-end version of the second-lien route.
On the DSCR side, 1.00 is where select programs start, not a universal standard. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage. Credit floors start at 620 in parts of the network, most programs want about 660, and 700 or better unlocks the strongest tiers. A standard DSCR loan runs up to $3,000,000 on standard programs (smaller balances available through select lenders). Extended 40-year terms and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them. The complete DSCR loans guide walks through the full program, which Lendmire arranges across 41 markets, including Washington, D.C.
Clearing 1.00 does not mean the property cash flows. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. The same caution applies to a line. The rent has to carry the first mortgage and the line’s floating payment, and neither product measures what is left after the other costs.
A line behind your first fits when:
- You are happy with the existing first mortgage and want to leave it alone.
- You hold title personally or in a revocable trust.
- Your credit profile is 700 or better, with DTI inside 50%.
- You need a modest amount against the equity, within the 70% CLTV ceiling.
Skip it and look at DSCR when:
- The rental sits in an LLC and you don’t want to change vesting.
- Your DTI is stretched, or you hold many financed properties.
- You want fixed-term structure rather than floating pricing.
- Your equity is thick but your personal income documentation is thin.
The call is close for borrowers with a strong credit profile and clean personal income. The line preserves the first mortgage, while the DSCR route replaces it but puts the property’s rent at the center. If you are leaving a first mortgage untouched, ask yourself whether the combined obligation still fits the rent with room to spare.
How to Screen Providers Before You Apply
Whether you work with a bank, a credit union, an online lender, or a broker, ask the same questions. Every answer should come back in writing.
1. What is the maximum CLTV on a non-owner-occupied property, and at what credit score?
2. Will the lender write a line behind my first mortgage if it isn’t the servicer?
3. Does the lender lend to my title structure, or does it require a vesting change?
4. How much of the line must be drawn at closing?
5. Does pricing ever convert to fixed, and what happens at the end of the draw period?
6. What valuation does the lender run, and can I request a full appraisal?
7. Is there a cap on the number of properties or lines I can have?
A broker that shops several wholesale lenders can run those answers against your file once. That is the practical advantage of the broker route: you are not guessing which single lender’s rules you happen to fit.
Frequently Asked Questions
Do I have to use the lender that already holds my first mortgage?
No. A standalone line in first or second lien position doesn’t require your first-mortgage servicer. The lender sizes the line against combined leverage and reviews your first-mortgage statement, your credit, and your DTI. Whether the first mortgage permits a junior lien is worth checking against your loan documents and title work before you apply.
Can I get a line on a rental held in an LLC?
Not on these programs. Only an individual borrower or a revocable living trust can hold title. A property already deeded to an LLC needs a vesting change, which may carry its own consequences, or a DSCR cash-out refinance instead. A DSCR loan can close in an entity, subject to program terms.
What happens if my equity is thin?
The line only gets sized against what remains under the CLTV ceiling. On an investment property that ceiling is 70%, and the program minimum line is $25,000. A first mortgage near that ceiling leaves almost no room. A DSCR cash-out, with an LTV ceiling of about 75% on standard rentals, may leave a little more room.
Will the line stay open if the property loses value?
Not necessarily. A lender can reduce or freeze a line if the property’s value falls, per the CFPB’s HELOC booklet, so an open line is not guaranteed to stay available at its original size. Keep in mind that at least 75% of the line is drawn at closing on the network’s programs, which means most of the borrowed amount is already outstanding and accruing interest from the first day.
Does my rent help me qualify?
Not directly. The line is underwritten on your credit and your DTI, qualified on the interest-only payment at the maximum draw. Rent income may appear in your documentation, but the property’s coverage ratio is a DSCR concept.
