The Quick Read: A second lien clears three tests: combined debt against property value, the borrower’s credit and debt-to-income, and eligible title and property type. On this network, investment properties cap at 70% combined loan-to-value, while primary residences and second homes reach 90% only at a 720 credit profile, subject to lender guidelines.
- The new lien sits behind the first mortgage, and the lender counts both balances against value.
- Occupancy sets the ceiling. Investment property is the tightest tier, at 70% CLTV with a 700 minimum credit profile.
- The line size tops out at $500,000 on investment property and second homes. Primary residences can go higher.
- The borrower must hold title personally or in a revocable living trust. An LLC cannot.
- A second lien is underwritten on the borrower, not on rent coverage. That is the main contrast with a DSCR loan.
Investors usually reach this topic from one of two directions. Either they hold a low-balance first mortgage and want equity without touching it, or they own a rental and wonder whether a second lien beats a refinance. The mechanics below cover both. They come from the wholesale network where Lendmire, a DSCR-focused mortgage broker, places these files.
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.
Key Terms Defined
Second lien. A loan recorded behind an existing mortgage. If the property is sold or foreclosed, the first lender is paid first.
Home equity loan. A set amount borrowed against equity, paid out as a lump sum. The name describes the structure, not the lien position.
Home equity line. A revolving line you can draw on repeatedly. On this network the product is a standalone line, and it can sit in first or second position.
Combined loan-to-value (CLTV). All liens on the property added together and divided by its value.
Subordination. A junior lender’s written agreement to stay behind a new first mortgage.
Debt-to-income (DTI). Monthly debts divided by monthly income. This is the personal ratio, not the DSCR ratio.
What Is a Second Lien Home Equity Loan?
It is a loan secured by the same property as your existing mortgage, recorded behind it. The label “second mortgage” names the lien position. The label “home equity loan” names how the money is borrowed. The two overlap whenever a first mortgage already exists.
The overlap breaks on a free-and-clear property. With no first mortgage, a new home equity loan takes first position. Nothing about the product changed, but the lien position did.
Two payments follow when a first mortgage stays in place. Both liens also come out of sale proceeds before the owner sees a dollar. This is why second liens are priced and sized more cautiously than first liens. The second lender gets paid only if the sale covers the first lender.
No federal statute sets a loan limit for investment-property second liens. Limits come from each lender’s program. That is why they differ so much from one lender to the next.
How Underwriting Treats a Second Lien, Step by Step
Underwriting a second lien is a sequence of tests. Each one can stop the file.
1. Occupancy is set first. Primary residence, second home, and investment property each carry their own credit minimum and CLTV ceiling. A file cannot borrow another tier’s number.
2. The equity test runs next. The lender adds the first mortgage balance to the requested line and divides by value. A program ceiling minus what is already owed is the room left. Only the first lien’s balance counts here. Its interest rate does not.
3. Borrower qualification follows. Credit score, tradelines, housing history, and DTI are reviewed. The ratio is qualified on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
4. Valuation is ordered. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may need a secondary valuation. A borrower can also request a full appraisal in any case.
5. Title and vesting are cleared. The lender checks who holds title and whether the property type is eligible. This is where entity-owned rentals fall out.
6. The lien is recorded behind the first. From then on, every later refinance or sale has to account for it.
A quick example in percentages only. Say a rental’s first mortgage sits at 55% of value. The investment ceiling is 70% CLTV, so the line can add at most 15 points of value, and only if credit, DTI, and title clear. If the first mortgage sits at 68%, the room is 2 points. That is rarely worth a file.
Requirements by Occupancy
Occupancy decides almost everything. Where the borrower lives and where the money is going determine which row of the table applies.
| Factor | Primary residence | Second home | Investment property |
|---|---|---|---|
| Minimum credit | 600 | 640 | 700 |
| Highest CLTV tier | 90% at 720+ | 90% at 720+ | 70% at 700+ |
| Maximum line | $750,000 | $500,000 | $500,000 |
| Draw structures | Two available | Two available | 5-year draw only |
The 90% figure exists only at a 720 credit profile and only on lines up to $500,000. Lower credit steps the ceiling down. On a primary residence, a 640 profile reaches 80% CLTV and a 600 profile reaches 60%. On a second home, a 640 profile reaches 75%. Investment property has no tier above 70%.
A line above $500,000 is available on a primary residence only. It requires a credit profile of 700 or better (720 on the longer-runway program, introduced below), caps at 75% CLTV, and requires a full appraisal. The program minimum line is $25,000.
Market surveys of equity lines on rentals report a wide spread of CLTV caps from lender to lender. Plenty of those figures run above what this network allows on an investment property. Treat the 70% figure here as the working number for investment collateral, subject to lender guidelines and full file review.
Structures and Variations
Lendmire brokers equity lines through two wholesale programs, and the figures differ between them. The higher-leverage program runs a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The longer-runway program runs a 5-year draw followed by a 25-year repayment. Investment lines use the 5-year structure only.
Pricing floats across both the draw and repayment periods on both programs. It does not convert to a fixed schedule. At least 75% of the line is drawn at closing. After closing, the longer-runway program sets a $1,000 minimum for each later draw.
Both programs let the line take first or second position. That matters for the free-and-clear case. If the property has no first mortgage, the same product becomes the first lien.
The two programs also differ on exposure. A borrower is limited 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.
The programs are also available only in 16 full-service states. That is narrower than the 41-market footprint for DSCR loans, so check state availability before building a plan around it.
Credit, DTI, and Derogatory History
The credit file is reviewed through a single-bureau score model keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not offered.
DTI tops out at 50%. Profiles from 600 to 679 are held to 45%. Anything above 45% needs a 680 minimum. Because the ratio is qualified on the interest-only payment at the maximum draw, a large line can fail a DTI test that a smaller line would clear.
Tradeline and housing-history standards vary by program. The longer-runway program wants two tradelines seasoned 12 months or one seasoned 24. It also wants housing history of 0x30x6 and 1x30x12 at 640 and above, applied across all financed properties.
A bankruptcy needs four years of seasoning from discharge or dismissal on both programs. Foreclosure history splits by program on primary residences and second homes. One program seasons a foreclosure at seven years and a deed-in-lieu, pre-foreclosure, or short sale at four. The other declines the history entirely, regardless of age. Investment files follow the seven-and-four-year path.
Property and Title: Where Files Fall Out
Eligible property types are single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. The 2-4 unit type needs a 640 minimum on the longer-runway program. Modular factory-built homes are eligible on the longer-runway program only.
These are not eligible on either program: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agricultural zoning. A property listed for sale, or listed within the past 60 days, is ineligible in several of the states served.
Title is the sharpest friction point for investors. Title must be held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change before the line can attach. Otherwise the cleaner path is a DSCR cash-out refinance, which can lend to an LLC borrower, subject to lender program eligibility.
Credit-limited borrowers face a further narrowing. Profiles below 640 are limited to single-family primary residences with a clean 12-month housing history under the longer-runway program. Second homes floor at 640 and investment at 700, so this restriction reaches primary residences only.
Second Lien Versus DSCR Cash-Out
The two products solve the same problem with different underwriting. A second lien leaves the first mortgage alone and is underwritten on personal credit, DTI, and equity. A DSCR cash-out replaces the first mortgage and is underwritten on whether the property’s rent covers its payment. Lendmire’s complete DSCR loans guide covers the full mechanics.
On most programs in the network, a DSCR cash-out refinance tops out around 75% LTV on a standard rental, with about six months of seasoning expected. Coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Credit floors run from 620 in parts of the network to about 660 on most programs. A score of 700 or better opens the strongest tiers.
Reserves vary by lender, leverage, loan size, and transaction type. Roughly six months of PITIA is common. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up toward nine months.
Clearing 1.00 does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation.
| Factor | Second lien line | DSCR cash-out |
|---|---|---|
| Underwritten on | Credit, DTI, equity | Rent against PITIA |
| First mortgage | Stays in place | Replaced |
| LLC title | Not allowed | Allowed, per program terms |
| Investment ceiling | 70% CLTV | Around 75% LTV |
The decision tends to turn on the first mortgage. A low-balance first mortgage with a strong personal profile favors the second lien. A thin personal DTI, an entity-held rental, or a first mortgage worth replacing favors the DSCR route.
Where the General Rule Breaks
Four edge cases cause most of the surprises.
A later refinance of the first mortgage. When an old first is paid off, the junior lien becomes the oldest recorded lien. A new first lender will not accept second position. The junior lender must sign a subordination agreement, and it has no duty to do so. In practice, a second lien can block a rate-and-term or cash-out refinance unless it is paid off first.
A zero balance. A line with no balance stays recorded until it is formally closed and released. A borrower who plans to refinance should get the release in hand first.
Business purpose versus consumer purpose. 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 label depends on how the loan proceeds are used, not on the word investment. Under Regulation Z’s business-purpose exemption, acquisition credit on an owner-occupied rental is deemed business-purpose above two units, and improvement credit above four. The official eCFR text is the place to check the wording. Compliance Alliance adds that a non-owner-occupied rental can be a single unit and still be exempt. Smaller owner-occupied properties are not automatically consumer credit or business credit. The lender decides case by case.
Borrowing against the home to fund a rental. Investors often use a primary-residence line for a down payment. That uses primary-residence terms, but it puts the home behind the new debt. If the rental underperforms, the equity at risk is the investor’s own house.
State rules add another layer. A few states impose waiting periods, one-lien limits, or CLTV caps on primary residences. The network’s guidelines flag these by state, and no investment property is held to the primary-residence rule.
Common Mistakes on These Files
- Assuming the highest tier applies. The 90% ceiling is a primary-residence and second-home number at 720. An investment file does not get it.
- Forgetting the entity. A rental held in an LLC cannot take the line until title moves.
- Ignoring the maximum-draw DTI test. The ratio is qualified on the interest-only payment at the full line, not on a smaller planned draw.
- Overlooking exposure caps. Three lines per borrower and the 15-property limit stop repeat borrowers.
- Skipping the subordination question. If a refinance of the first mortgage is likely, plan for the junior lender’s consent.
- Treating DSCR coverage as cash flow. The ratio ignores everything but rent and PITIA.
What the Investor Decision Looks Like
Start with occupancy and title. If the property sits in an LLC, the second lien is off the table until vesting changes. Next, compute CLTV with the first mortgage balance. If the room left is thin, the line will be too small to matter.
Then compare the two products. A second lien keeps a low-balance first mortgage intact and runs on personal credit and DTI. A DSCR cash-out reaches higher leverage on a rental and runs on rent coverage. The two are not mutually exclusive across a portfolio, but exposure caps and subordination limit stacking.

Frequently Asked Questions
Is a home equity loan the same as a second mortgage?
Only when a first mortgage already exists. “Second mortgage” names the lien position, and “home equity loan” names the lump-sum structure. On a free-and-clear property, a new home equity loan takes first position.
What is the maximum CLTV on an investment property?
On this network it is 70% CLTV, with a 700 minimum credit profile and a $500,000 maximum line. Higher ceilings exist only on primary residences and second homes, and the 90% tier needs a 720 credit profile. Figures are subject to lender guidelines and full file review.
Can an LLC take a second lien home equity line?
No. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance can be considered instead, depending on program guidelines.
Will a second lien block a later refinance of my first mortgage?
It can, because the new first lender will not sit behind the junior lien. The junior lender must agree to subordinate, and it can refuse. Paying off the second lien before the refinance is the cleaner route.
Does the line need an appraisal?
Not ordinarily at or below $500,000, where an automated valuation usually applies. A higher CLTV can require a secondary valuation. Every line above $500,000 requires a full appraisal, and a borrower can request one at any size.
