The Quick Read: Which provider you can use depends on lien position and combined leverage, not on a brand name. Most equity lines sit in first or second position, so a property that already carries a second lien usually leaves no room for a third. Your real choices are to replace that second lien, tap a different property, or move to a rent-based cash-out.
- A new line behind an existing second lien is a third lien, and few providers will write one.
- An existing line counts at its full limit, not just the drawn balance.
- Across Lendmire’s wholesale network, the investment-property ceiling is 70% combined loan-to-value.
- A DSCR cash-out refinance pays off every lien and qualifies primarily on property-level rental income, subject to lender guidelines.
A ranked list of providers would mislead you, because the provider that fits is the one whose rules match your lien stack, your equity, and your occupancy type. Lendmire is a mortgage broker, not a lender. It places files with select wholesale lenders in its network, so this piece explains what those lenders look for and who fits.
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 Is a “Second Mortgage,” Really?
A second mortgage is defined by lien position, not by product type. A lien is a recorded claim against the property. The order in which claims are recorded sets who gets paid first if the property is sold in a forced sale.
A HELOC (home equity line of credit) is a revolving line you borrow against repeatedly. If nothing is recorded ahead of it, it is a first lien. If a first mortgage exists, the line is a second. Bills.com explains that lien position follows what is already recorded against the property.
Now add your situation. You have a first mortgage and a second lien, such as a home equity loan or another line. A new HELOC lands in third position.
That matters because the first lien is paid in full first, then the second. The third gets paid only from what is left. Financedevil notes that very few lenders will sit in third position, and those that do look harder at equity, credit, and debt load. Nothing in law caps a property at one equity line. The limit is lender appetite and the equity left over.
How Underwriting Treats a Stacked Lien, Step by Step
Underwriting a new line behind an existing second lien follows a fixed order. Each step can end the conversation, so it helps to run them yourself before you apply.
Step 1: List every recorded lien. Lien rank follows recording order, not the name of the product. A line with a zero balance is still a lien until it is formally closed and released.
Step 2: Compute combined loan-to-value. CLTV is all loans secured by the property, divided by current value. Some lenders call it HCLTV when a line is involved.
Step 3: Count the full limit of the existing line. The math adds the first mortgage balance, the full credit limit of the existing line, and the new line you want. An undrawn line still uses up headroom.
Step 4: Apply the occupancy tier. Rentals get stricter limits than primary homes. NerdWallet says an investment-property HELOC is possible, but the lender pool is smaller, requirements are strict, and you can’t borrow as much as against a primary home.
Step 5: Check credit, debt-to-income, and valuation. Credit and DTI drive most HELOC decisions, and the property’s rent does not. Across the network, DTI tops out at 50%, and it is measured on the interest-only payment calculated on the maximum draw. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. A full appraisal is required above $500,000, and you can request one at any size.
Step 6: Decide whether to pay off, subordinate, or stack. Stacking means keeping the old second lien and adding a third. Payoff means the new line retires the old second. Subordination matters when a first mortgage is refinanced: the old lien releases, and the second would jump to first position unless its holder signs an agreement to stay behind. Bills.com notes that lenders generally charge a fee for this and often apply a CLTV threshold.
Worked Example: Where the Equity Goes
The percentages below are modeled assumptions, not market data. Each is a share of the property’s current value.
Say your first mortgage balance is 55% of value. Your existing second line has a limit of 20% of value, and you have drawn very little of it. You want a new line equal to 15% of value.
Stacked, the CLTV is 55 + 20 + 15 = 90%. On an investment property, the network ceiling is 70% CLTV. The stack fails at that tier before credit even comes up. Even at a 720-plus score on a primary residence, where the program reaches 90% CLTV on lines up to $500,000, a third position is outside what these programs write.
Now replace instead. The new line pays off the old second. The stack becomes 55 + 15 = 70%. That fits the investment ceiling exactly, provided the borrower also meets the 700 credit minimum and the other rules below. The same swap fits comfortably under the primary-residence tiers.
Network Programs: What These Lenders Look For
Through its wholesale network, Lendmire places standalone home equity lines in first or second lien position. Programs differ by occupancy, and the ceiling depends on which type you hold. These figures are guidelines, subject to lender review and full file underwriting, and they are not a commitment to lend.
| Factor | Investment property | Primary / second home |
|---|---|---|
| Max CLTV | 70% | Up to 90% at 720+ |
| Minimum credit | 700 | 600 primary; 640 second home |
| Max line | $500,000 | $750,000 primary; $500,000 second home |
| Draw structure | 5-year draw, 25-year repayment | 3-year or 5-year draw options |
A few details sit behind that table:
- Ceilings are occupancy-tiered. On a primary residence, the 90% CLTV tier exists only at 720 or better and only up to $500,000. On a second home, the 90% tier also requires 720 or better.
- Lower credit means lower leverage. A primary residence at 620-plus tops out at 70% CLTV up to $400,000. Investment lines start at a 700 score.
- Lines above $500,000 are primary-residence only. Investment and second-home lines stop at $500,000. A primary-residence line above that needs 700 or better (720 on the longer draw structure), caps at 75% CLTV, and requires a full appraisal.
- Draw and repayment are fixed by program. A line has an interest-only draw period followed by a fully amortizing repayment period. At least 75% of the line is drawn at closing, and the payment floats across both periods and never converts to fixed.
- Subsequent draws start at $1,000 on the program that states a minimum.
- Credit is read from one score. It is a single-bureau score keyed to the primary wage earner, and the report must be no more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal.
- Property types are limited. Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not.
- Availability is narrower than DSCR. HELOC lines are available in 16 full-service states, while DSCR investor loans reach 40 states plus Washington, D.C., or 41 markets total.
Market surveys report that investment-property equity lines often want 20% or more equity, per NerdWallet. That is a market-wide statistic. On Lendmire’s network, the investment-property ceiling is 70% CLTV.
Key Terms Defined
Lien position: The order in which claims against a property are recorded, which sets who is paid first in a forced sale.
Third lien: A claim recorded behind both a first mortgage and a second lien.
CLTV (combined loan-to-value): All loans secured by the property divided by its current value.
Subordination agreement: A signed agreement in which one lienholder agrees to stay behind another after a refinance.
Closed-end second: A lump-sum second loan with no future draws, unlike a revolving line.
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly obligation of principal, interest, taxes, insurance, and any HOA dues.
Seasoning: The waiting period a lender wants between buying a property and refinancing it.
Which Kind of Provider Fits Which Situation?
The right provider type depends on your lien stack and how the property is titled. Naming companies would help less than you might expect, because rules differ from one lender to the next.
| Provider type | Fits best when | Watch out for |
|---|---|---|
| Your current servicer | Simple first mortgage, rental HELOC offered | Many don’t offer rental lines |
| Credit unions, regional banks | Smaller loans, relationship borrowers | Some allow LLC title, many don’t |
| Large retail lenders | Primary home, one existing lien | Often stop at second position |
| Broker with wholesale lenders | Stacked liens, odd titling, comparison | Program rules differ lender to lender |
Your current servicer is the obvious first call, though it may not offer what you need. BiggerPockets shows an investor whose servicer did not offer lines on rentals at all. That is one case, not a pattern, but it explains why shopping matters.
A broker adds something a single lender cannot. It sees many lenders’ guidelines at once and matches your scenario to the program whose rules you meet. The best program for your situation depends on property type, credit profile, how much leverage you need, and how the property is titled. That is a matching problem, and it is what Lendmire does.
Stack, Replace, Refinance, or Pay Down?
When a third lien is not available, you have four routes. None is right for everyone.
| Route | What happens | Best when |
|---|---|---|
| Stack | Keep old second, add third | Rare; needs a specialty lender |
| Replace | New line pays off old second | Combined stack fits the tier |
| Cash-out refi | New loan pays off every lien | Equity is large, rent is strong |
| Pay down | Reduce the second first | Stack is slightly over the cap |
Stacking is the narrowest road. Specialty lenders write it, and Financedevil says they underwrite it closely. It is lender-specific, so it is hard to plan around.
Replacing works when the new combined number fits the occupancy tier. It also removes the need for a subordination agreement, since the old lien is gone.
A cash-out refinance swaps the whole stack for one loan. Paying down is the honest answer when you are a few points over a cap and have the cash.
Where the General Rule Breaks
A few situations bend the usual rules, and each one changes the answer.
LLC-titled rentals. The network’s equity lines require the individual borrower or a revocable living trust to hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. A BiggerPockets lender comment (HELOCs for investment property) says some credit unions and regional banks allow LLC title, and that the usual pivot when HELOC desks pass is a closed-end second or a rent-based second. If your property is already deeded to an LLC, the options are a vesting change or a DSCR cash-out refinance.
A paid-off property. With no mortgage, a line is the first lien. Lenders often allow more room in first position than in second. Any stacked-lien problem disappears.
A different property. Financedevil calls this the far more common path. Tap equity in a property that has no stacked liens, and leave the tangled one alone.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs or its equity-line programs. Those owners need a different route entirely.
Listing status. A property that is listed for sale, or was listed within the past 60 days, is ineligible in several states.
Exposure limits. A borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible for the equity-line programs.
The Pivot: A DSCR Cash-Out When No Line Fits
A DSCR cash-out refinance is the natural fallback when the stack won’t fit a line. 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 loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It pays off every lien at closing, so no one sits in third position. It also avoids subordination fees. LLC-titled properties are generally eligible, subject to lender program eligibility.
Here is how the network’s DSCR cash-out programs generally look:
- Leverage: Cash-out on a standard rental tops out around 75% LTV across most of the network.
- Seasoning: About 6 months of ownership is the common expectation.
- Coverage: A 1.00 ratio is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Credit: A 620 floor exists in parts of the network. Most programs want around 660, and 700-plus unlocks the strongest leverage tiers.
- Loan size: Up to $3,000,000 on standard programs, with smaller balances available through select lenders.
- Reserves: They vary by lender, leverage, and loan size, commonly around 6 months of PITIA (principal, interest, taxes, insurance, and association dues).
One caution. A ratio above 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. The complete DSCR loans guide covers how the ratio is built.
What Does the Decision Look Like in Practice?
Picture an investor with a duplex, a first mortgage, and an old home equity loan taken years ago for a renovation. They want a new line for the next purchase. The stack is over the investment ceiling, and the LLC title blocks an equity line anyway. The investor compares paying off the old loan with a refinance of the whole stack. With strong rent against the full payment, the DSCR route is often where the numbers close, and a broker can check the leverage and coverage tiers across several lenders.
Compare an owner-occupant with the same stack on a primary residence and a 720 score. Replacing the old second with a larger new line may fit inside the 90% tier on a line up to $500,000. Same stack, different answer, because occupancy sets the ceiling.
Variable payments deserve a thought too. Draws are usually interest-only and the payment floats, per NerdWallet’s investment-property explainer, which can strain thin rental income. The federal consumer finance regulator’s HELOC explainer also warns that falling behind could cost you the home. Lenders can generally freeze or reduce a line if the property’s value drops.
Before you apply, gather this checklist:
1. A current statement for each lien showing balance, limit, and draw status.
2. Proof of income and a credit report no older than 90 days at closing.
3. Vesting documents and proof of insurance.
4. An estimate of current value, knowing automated tools won’t capture rehab value (a full appraisal is needed then).

Frequently Asked Questions
Can I get a new HELOC if I already have a home equity loan on the same property?
Usually only by replacing it. Equity lines on Lendmire’s network sit in first or second position, so a new line behind both a first mortgage and an existing second would be a third lien. Using the new line to pay off the old second, or choosing a DSCR cash-out that pays off everything, is the more workable route.
Does my unused HELOC count against me?
Yes. The lien stays until the line is formally closed and released, and CLTV counts the full credit limit, not the drawn balance. If you never use an old line, closing it can restore real headroom for a new one.
Must I use my current mortgage lender?
No. Your servicer is a reasonable first call, but many don’t offer lines on rentals. A broker with wholesale lenders can compare programs by occupancy, credit, and combined leverage.
What is the maximum CLTV on a rental property line?
On Lendmire’s network, the investment-property ceiling is 70% CLTV with a 700 minimum score, on lines up to $500,000. Higher figures, such as 90%, apply only to primary residences and second homes at 720-plus.
Can an LLC-owned rental get an equity line?
Not through these programs. Title must be held by the individual borrower or a revocable living trust. A property already in an LLC needs a vesting change, or a DSCR cash-out, which is generally available for LLC-titled property subject to lender program eligibility.
