The Quick Read: A home equity line sits behind your first mortgage as a second lien, so the first loan’s balance, rate, and term stay exactly as they are and only the new money is priced at today’s market. A cash-out refinance does the opposite. It pays off the first loan and replaces the whole balance with a new one. The tradeoff is that a line floats, and investment-property lines in Lendmire’s wholesale network are tighter than primary-residence lines.
- A second lien leaves the first mortgage untouched. A cash-out refinance reprices the entire balance.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 credit floor and a $500,000 maximum line.
- On a primary residence or second home, the ceiling reaches 90% CLTV, and only at 720 or better.
- A line is underwritten on the borrower, not on rent. A DSCR cash-out is underwritten on the property’s rent.
- Pricing floats through the draw and repayment periods. It never converts to fixed.
A large share of owners are holding a loan they would never get today. Wolf Street’s analysis of FHFA data reports that 19.5% of mortgages outstanding were below 3% in the first quarter of its latest reading. That is why “borrow against the equity without touching the first loan” is now a mainstream question, and why it deserves a mechanical answer instead of a slogan.
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.
Lendmire is a mortgage broker. It places these lines through select wholesale partners and is never the lender. Every figure below is subject to lender guidelines and full file review, and nothing here is a commitment to lend. Home equity lines through this channel are available in Lendmire’s 16 full-service states, which is narrower than the 41-market DSCR footprint.
What Does “Keep the Low First” Actually Mean?
It means the new loan is a second lien. The first mortgage keeps its balance, rate, and amortization schedule. The new lender gets a claim that ranks behind the first lender, so it cares a great deal about how much equity is left after the first balance is counted.
The CFPB’s HELOC brochure describes a line as a loan you borrow against, spend, and repay as you go, with the home as collateral. Pricing is an index plus a margin. Common indexes are the U.S. prime rate and the constant-maturity Treasury rate.
A standalone line can sit in first or second position. This is the first decision on the file. If the property already carries a mortgage and you want to keep it, the line has to go in second position on purpose. On a paid-off property the line becomes the first lien by default.
Key Terms Defined
CLTV (combined loan-to-value): The first-mortgage balance plus the full line limit, divided by the property value.
Second lien: A loan that ranks behind the first mortgage if the property is ever sold or foreclosed.
Draw period: The stretch of the line where you can borrow, usually with interest-only minimums.
Repayment period: The stretch after the draw period where the balance amortizes fully.
DTI (debt-to-income): Monthly debts, including the kept first mortgage payment, divided by monthly income.
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly obligation on the property. It is a rent test, and a line does not use it.
How Underwriting Treats a Line, Step by Step
Underwriting a line is a borrower test with an equity test layered over it. The steps run in a predictable order.
1. Equity test. The lender adds the first-mortgage balance and the full line limit, then divides by value. The result must sit under the CLTV ceiling for your occupancy and credit tier. The first balance eats the ceiling first.
2. Line sizing. Take value, apply the ceiling percentage, subtract the first balance, then cap at the program maximum. The CFPB booklet example walks through the same arithmetic with a $100,000 home, a 75% ceiling, $40,000 owed, and a $35,000 line. That example is illustrative only. Real ceilings depend on the tiers below.
3. Credit. The network uses a single-bureau score keyed to the primary wage earner, with a 600 program floor. The report cannot be more than 90 days old at closing, and rescores are not allowed.
4. Income and DTI. DTI tops out at 50%. It drops to 45% for profiles from 600 to 679, and anything above 45% needs a 680 minimum. The file is qualified on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
5. Valuation. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal, though a higher CLTV can trigger a secondary valuation. Every line above $500,000 needs a full appraisal, and a borrower may request one in any case.
6. Title and property review. Vesting, property type, and any listing activity get checked before the deal moves forward.
Documentation that trips files here is mundane: a stale credit report, a first-mortgage statement that doesn’t match the payoff figure, and a vesting problem nobody caught until title work.
The Occupancy Tiers That Set Your Ceiling
The ceiling depends on how the property is used, and the tiers are not interchangeable. Quote the one that matches the property.
| Occupancy | Top CLTV | Credit needed | Max line |
|---|---|---|---|
| Investment property | 70% | 700+ | $500,000 |
| Second home | 90% | 720+ | $500,000 |
| Primary residence | 90% | 720+ | $500,000 at 90% |
| Primary residence, large line | 75% | 700+ (720 on one structure) | $750,000 |
Read the table carefully. On an investment property, 700 and 720 carry the same 70% ceiling, so a higher score does not buy more leverage on a rental. The minimum credit is 700 on investment lines, 640 on second homes, and 600 on primary residences. On a primary residence, tiers step down from 90% at 720 through 85%, 80%, 70%, and 60% as credit drops toward the floor.
Lines above $500,000 are primary-residence only. The credit requirement for that size is 700 or better (720 on the longer-runway structure), the CLTV caps at 75%, and a full appraisal is required. Minimum line size is $25,000 (Michigan floor is $10,000).
Structures and Variations
Lendmire’s wholesale network has two draw structures. On primary residences and second homes, the first has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The second has a 5-year draw followed by 25 years of repayment, and it is the longer-runway structure. Investment lines run the 5-year draw and 25-year repayment only. Tennessee shortens both structures: 3 years and 12 years on the first, 5 years and 10 years on the second.
Three features apply on both structures:
- At least 75% of the line is drawn at closing. It is not a free zero-balance cushion.
- Pricing floats across the draw and the repayment period and never converts to fixed.
- Later draws carry a $1,000 minimum, with Texas at $4,000, as stated by the longer-runway program.
Balloon and payment-shock risk is real. The CFPB’s booklet describes a balloon payment, where an interest-only or low-principal plan leaves a large balance you must be ready to refinance or pay. The CFPB brochure also notes that variable-rate payments can change even if you draw nothing more. When the draw period ends and amortization starts, the monthly obligation steps up. Stress-test that step before signing, not after.
Where the General Rule Breaks
Several edge cases catch borrowers who assumed a line works like any other loan.
Title. Only the individual borrower or an inter vivos revocable living trust can hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. A property already deeded to an LLC needs a vesting change, or the better path is a DSCR cash-out.
Property type. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Modular homes qualify on the longer-runway structure only. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Texas primary residences. A Texas primary is a homestead and caps at 80% combined loan-to-value, with a 12-day waiting period, a one-lien-at-a-time rule, and 12-month seasoning. Texas second homes and investment properties are eligible as non-homestead transactions.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. New Mexico and Ohio apply a CLTV cap that depends on the credit profile.
Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program on primary residences and second homes. One program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines the history entirely. Investment files follow the 7-and-4-year path.
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.
Consent from the first lender. Many borrowers assume the first mortgage’s due-on-sale clause is irrelevant. The note’s additional-lien language still controls, and any protection in federal law may not reach a non-owner-occupied rental. Read the note, then confirm with the servicer or counsel.
Refinancing the first later. The line must be paid off or subordinated, and the junior lender is not obliged to subordinate. Ask before opening it.
Scarcity. Many large retail lenders will not write a line on a rental that still carries a mortgage. A decline from one of them is usually a product-policy answer, not a verdict on the borrower. Lendmire’s network exists partly because that gap is real.
HELOC or DSCR Cash-Out: Which Test Fits the File?
The two products test different things, and that split decides most investor files.
| Factor | HELOC (second lien) | DSCR cash-out |
|---|---|---|
| What it tests | Borrower credit, income, DTI | Property rent vs. full payment |
| First mortgage | Stays in place | Paid off and replaced |
| Investment ceiling | 70% CLTV | About 75% LTV on standard rentals |
| Vesting | Individual or revocable trust | Often LLC-eligible, subject to program |
| Pricing | Floats throughout | Fixed structures available |
A DSCR cash-out on a standard rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. Short-term-rental collateral runs lower, with a 70% cash-out ceiling. Coverage of 1.00 is where select programs start, and stronger ratios open better leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. Lendmire’s complete DSCR loans guide covers those programs in full.
The practical split is simple. Strong personal income with a rental that has thin coverage suits the borrower-based line. Strong rent coverage with messy or hard-to-document income suits DSCR first.
One caution on the DSCR side. Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside it.
If a second lien goes onto a property that already has a DSCR first, the combined obligations have to be run through the coverage math. Lendmire’s piece Rental HELOC CLTV Ceilings When You Want to Keep Your Low First Lien covers the equity side in more depth.
The Blended-Cost Question
A cash-out refinance reprices the whole balance. A line prices only the new draw. That is the core reason the second lien can win when the first loan is far below the current market.
Run it as a blended cost over your expected holding period. Weight the kept first balance at its existing cost, weight the new draw at the floating cost, and add closing costs spread across the years you will hold. A line can lose that comparison in a few cases:
- The new money is large and will be carried for many years.
- The gap between your first mortgage and the market is narrow.
- You want one fixed payment and no exposure to a floating balance.
- The property’s cash flow is thin and cannot absorb a payment step-up.
A cash-out refinance can still come out ahead when the numbers improve over your holding period. Skip the line if the draw is large relative to rent, or if the floating exposure keeps you up at night.
What the Investor Decision Looks Like in Practice
Picture an investor holding a rental with a first mortgage far below today’s market, who wants cash for a down payment on the next property. A line supplies cash only. The next purchase still needs its own loan or an all-cash closing. Typical purchase leverage on the DSCR side runs 75% to 80% LTV, with select high-leverage programs reaching 85% at roughly a 700+ score. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Now consider a recent purchase being run as a BRRRR. A brand-new purchase has little equity above the purchase loan, so a seasoned rental is the better collateral. Sequencing matters too. A recent cash-out refinance on the same property can trigger a denial.
Say you own a rental with a good score but the title sits in an LLC. The line is off the table until the vesting changes. At that point a DSCR cash-out may be the cleaner path, with loan sizes that vary by program and lender, and reserves commonly around 6 months of PITIA, varying by lender, leverage, and loan size. For loans above $1,500,000, reserves typically step up toward 9 months.
Tax treatment varies; consult a qualified professional before relying on any deduction.
A pre-application checklist keeps the file clean:
1. Pull the first-mortgage note and read the additional-lien clause.
2. Confirm how the property is titled.
3. Get a current payoff or balance statement for the first loan.
4. Check the property type against the eligibility list.
5. Confirm no listing activity on the property.
6. Decide how much of the line you will draw at closing, remembering the 75% minimum.
The site also carries an illustrative calculator for rough comparisons, which is an estimate only and not a quote.
Frequently Asked Questions
Will a HELOC change my first mortgage?
No. The first loan keeps its balance, rate, and term. The new line sits behind it as a second lien. The first balance still counts against you, because it uses up combined loan-to-value before the line is sized.
Does the kept first mortgage payment count against me?
Yes. It counts in DTI, which tops out at 50% on the network. The file is also qualified on the interest-only payment calculated on the maximum draw, not on the amount you actually plan to borrow.
Can an LLC own the property?
Not for this product. Title must be held by the individual or a revocable living trust. A property already in an LLC needs a vesting change, or a DSCR cash-out may fit better, subject to lender program eligibility.
Is the rate fixed after I draw?
No. Pricing floats through both the draw and repayment periods and never converts to fixed. The CFPB notes that variable-rate payments can change even when you draw nothing more.
Does a higher score get me more leverage on a rental?
Not on an investment line. Both 700 and 720 profiles carry the same 70% CLTV ceiling, with a $500,000 maximum line.
When does DSCR cash-out make more sense?
When rent coverage is strong and personal income is hard to document. A DSCR cash-out qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
