The Quick Read: The right fit is a standalone second-lien line that sits behind the first mortgage you keep, so your existing loan keeps its balance, term and pricing, while the right program for your situation depends on occupancy, credit profile, combined leverage, and how the property is titled.
- The line is a separate loan. Your first mortgage is not refinanced, paid off, or re-underwritten.
- Your first mortgage still counts. Its balance eats into your combined leverage, and its payment counts in your debt-to-income ratio.
- The ceiling depends on how the property is used. Investment-property lines top out at 70% combined loan-to-value, while primary-residence and second-home lines can go higher with stronger credit.
- Title matters. Lines are written to individuals or revocable living trusts, not LLCs.
- A broker that shops several wholesale lenders can match the file to the program that fits, but every figure is subject to lender guidelines and a full file review.
What Does “Without Touching Your First Mortgage” Actually Mean?
It means a second mortgage. A line of credit on a property that already has a loan sits in second position, behind the first. The first loan keeps its balance, term, and payment. Nothing about it gets replaced.
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.
A cash-out refinance does the opposite. It pays off the old loan and writes a new one for the full balance. That resets everything on the first loan, including a rate and term you may have wanted to keep.
A home equity line of credit (HELOC) is a revolving line. You borrow against your equity, which is the property’s value minus what you owe. You pay interest-only during a draw period. Then the line moves to a repayment period where the balance amortizes. That means each payment includes principal, so payments step up.
One confusing wrinkle: some lines can sit in first position when there is no mortgage at all. That is a different situation from the one you are asking about. If a program calls itself a first-lien line and you still owe on your mortgage, it is built to replace that mortgage. Skip it.
What Still Counts When the First Mortgage Stays Put?
Untouched does not mean invisible. Underwriters see the first mortgage in two places.
Combined leverage. Combined loan-to-value (CLTV) adds your first-mortgage balance and the new line, then divides by the property’s value. The line’s ceiling is the maximum CLTV times value, minus what you owe on the first.
Debt-to-income. Debt-to-income (DTI) compares your monthly debts to your income. The first mortgage payment is in that number. So is the new line, calculated on the interest-only payment of the maximum draw, not just what you borrow.
Run a quick example in percentages. Say an investment property carries a first mortgage equal to 45% of its value. The investment ceiling is 70% CLTV, so the line has room up to 25% of value. If the first mortgage is only 30% of value, the room is up to 40%, but the line still caps at $500,000 on investment property. A larger first mortgage shrinks the room one for one.
How Do You Judge the Best Program for Your Situation?
The best program for your situation is the one whose rules fit your property, credit, and plans. Across our wholesale network, programs differ on a handful of points. Check these six before you compare anything else.
1. Occupancy. Primary residence, second home, and investment property each have their own ceiling and credit floor.
2. Combined leverage. Your first mortgage balance plus the line must fit under the CLTV cap for your credit tier.
3. Credit profile. The program floor is 600, but the floor and the leverage both rise with the property type. Lenders use a single-bureau score tied to the primary wage earner, and the report must be no more than 90 days old at closing.
4. Income and DTI. The maximum is 50%. It drops to 45% for credit profiles from 600 to 679. A ratio above 45% requires at least a 680.
5. Title and vesting. The borrower must hold title as an individual or in a revocable living trust.
6. Property type. Not every property is eligible. See below.
Lendmire is a mortgage broker, not a lender. It arranges these lines through select wholesale partners in the network, and the lender reviews and approves the file. That is why one question matters most: which lender’s rules match your file. A broker can test several programs against the same scenario.
What Are the Network’s Ceilings by Occupancy?
Ceilings depend on how the property is used. Never read a primary-residence figure as an investment-property figure.
| Occupancy | Max CLTV | Credit pairing | Max line |
|---|---|---|---|
| Primary residence | 90% | 720+ | $500,000 |
| Primary residence | 75% | 700+ (720 on the longer-runway program) | $750,000 |
| Second home | 90% | 720+ | $500,000 |
| Investment property | 70% | 700+ | $500,000 |
Lower credit tiers step the primary-residence ceiling down. A 640 profile reaches 80% CLTV, a 620 reaches 70%, and the 600 floor reaches 60%, with smaller maximum lines at the bottom tiers. Second homes floor at a 640 score. Investment property floors at 700.
Two quick notes. First, 90% exists only at a 720-or-better credit profile. It is not a general ceiling. Second, an investment line never goes above 70%, regardless of credit.
Wholesale programs here come in two shapes. A shorter-runway, higher-leverage shape has a 3-year interest-only draw and a 17-year repayment. Investment lines run the 5-year draw and 25-year repayment structure only. Pricing floats during both periods and never converts to fixed. At least 75% of the line is drawn at closing.
That last point changes how the line behaves. It is revolving on paper, but most of it is funded on day one. Do not plan on opening a large line and leaving it idle. After closing, later draws start at $1,000.
Which Properties Qualify?
Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. A 2-4 unit property needs at least a 640 on the longer-runway shape. Modular factory-built homes are eligible on that shape only.
Not offered on either shape: manufactured homes, co-ops, condotels, log homes, commercial property, mixed-use, and agricultural zoning.
Title is where investors most often get stuck. These lines cannot be written to an LLC, corporation, partnership, or an irrevocable, blind, or land trust. A property already deeded to an LLC needs a vesting change first. Or, if a change does not work for you, a DSCR cash-out refinance may be the route instead, subject to program terms. The title restriction is the sharpest structural difference from a DSCR loan, which allows entity ownership.
Other limits: a borrower can hold up to three lines. Combined exposure caps at $2,000,000 on the higher-leverage shape and $750,000 on the longer-runway shape. A borrower with more than 15 financed properties is not eligible. Availability runs through Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. A few states also shorten draw schedules or add waiting periods on primary residences, and some bar properties listed for sale within the past 60 days.
How Does This Compare With the Other Ways to Reach Equity?
| Factor | Second-lien HELOC | Home equity loan | Cash-out refinance |
|---|---|---|---|
| First mortgage kept? | Yes | Yes | No, replaced |
| Funding | Revolving line | One lump sum | One lump sum |
| Pricing | Floats | Typically fixed | Resets on full balance |
| Payments | Two | Two | One |
| Best fit | Keep a low first loan | Fixed one-time need | Better terms on whole loan |
A home equity loan is also a second lien, but it pays out as a single sum. A cash-out refinance on a standard rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. An investment-property line stops at 70% CLTV. The refinance can reach more cash, but it resets the whole first loan to do it. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
If the first loan is a DSCR loan, check its note before you apply. Its documents must allow subordinate financing. If they do not, a refinance may be the only way to reach the equity. Lendmire’s complete DSCR loans guide explains how those loans are structured.
Which Route Fits Your Situation?
| Your situation | Likely route | Why |
|---|---|---|
| Low first loan, need partial equity | Second-lien line | First loan unchanged |
| Rental deeded to an LLC | DSCR cash-out | Lines can’t be titled to an LLC |
| Need above 70% on a rental | Cash-out refinance | Investment lines stop at 70% CLTV |
| First loan isn’t worth keeping | Cash-out refinance | Replaces the whole loan |
| Property is paid off | First-lien line | No first mortgage to protect |
| Need over $500,000 on a rental | Cash-out refinance | Investment lines cap at $500,000 |
An honest read: a line wins when the first loan is worth protecting and you need a slice of equity. It loses when you need more leverage, more cash, or an entity-owned property.

What Do Lenders Check on These Files?
Lines of $500,000 or less ordinarily run automated valuation with no traditional appraisal. A higher CLTV can trigger a secondary valuation, and you can always request a full appraisal. Every line above $500,000 requires one.
Credit history gets a closer read. The longer-runway shape wants two tradelines seasoned 12 months, or one seasoned 24. Housing history of 0x30x6 and 1x30x12 applies at 640 and above, and 0x30x12 from 600 to 639. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years. A deed-in-lieu, pre-foreclosure, or short sale needs 4. On primary residences and second homes, one shape seasons a foreclosure in 7 years while the other declines foreclosure history regardless of age.
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), a 75% CLTV cap, and a full appraisal.
Where Does the General Rule Break?
Edge cases come up on almost every file. These are the ones that cost investors time.
The first mortgage’s own rules. Some loans restrict subordinate financing. Pull the note before you apply. A lender cannot work around a clause that bars a second lien.
Entity ownership. If your portfolio runs through LLCs, this product is the wrong tool for those properties. It fits a rental you hold personally or in a revocable trust.
Large lines. Over $500,000 narrows to primary residences. An investor cannot stack a bigger line on rental property.
Cash for the next purchase. The line supplies cash only. The next property still needs its own purchase loan or an all-cash closing. The line is not closed with that purchase.
Refinancing the first later. The line stays in second position. A later refinance of the first usually requires the line holder to agree to stay behind the new loan. Plan for that conversation.
Business-purpose loans. Many investor lines are used for business purposes, and the rules differ from a standard owner-occupied home equity line. The commentary to the federal home-equity-plan rule says there is no precise test for primary purpose. The more closely the credit relates to a business purpose, the more likely it is treated that way. Your lender makes that call, not you.
What Are the Risks?
A second lien stacks risk on the same collateral. The CFPB explains that falling behind on a HELOC can cost you the home. Leaving the first mortgage alone does not shield it from that.
Pricing floats. HELOC pricing is typically variable, and these lines never convert to fixed. Payments step up at the draw-to-repayment switch.
Leverage rises. A second lien thins the cushion if values fall. Add the line payment to your rental cash-flow math, and do it before you borrow.
Also keep one thing straight. Clearing a lender’s coverage test does not mean the property cash flows. Repairs, vacancy, management, and utilities sit outside the numbers a lender checks.
Key Terms Defined
CLTV (combined loan-to-value): Your first-mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line and pay interest only.
Repayment period: The stretch after the draw ends, when the balance amortizes and payments rise.
Second lien: A loan that sits behind the first mortgage and is paid second if the property is sold or foreclosed.
DTI (debt-to-income): Your monthly debt payments divided by your monthly income.
Vesting: How title to the property is held, such as an individual, a trust, or an LLC.
Before You Apply
- Pull your first-mortgage statement and read the note for subordinate-financing limits.
- Confirm how title is held. Move it out of an LLC first if the product requires it.
- Estimate value and balance, then work out your CLTV against the ceiling for your property’s occupancy.
- Check your credit report. It must be no more than 90 days old at closing.
- Gather proof of income and housing history for DTI.
- Decide how much cash you really need, since 75% of the line is drawn at closing.
Frequently Asked Questions
Does a HELOC change my first mortgage’s rate or terms?
No. A line taken behind your first mortgage is a separate loan. Your first loan keeps its balance, term, and pricing. The line has its own pricing and payment, and your first mortgage payment still counts in your debt-to-income ratio.
Do I have to refinance to get a HELOC on a rental?
No, but you need a lender that writes lines on investment property, and many large retail lenders limit lines to the home you live in. Through a broker, the network program caps at 70% CLTV on an investment property with a 700 minimum credit score. Subject to lender guidelines, a file that does not fit may point toward a cash-out refinance.
Can I use an LLC-owned rental?
Not directly. Title must be held by an individual or a revocable living trust. A rental already deeded to an LLC would need a vesting change first, or a different product such as a DSCR cash-out refinance, depending on program terms.
Can I open the line and not draw on it?
Not entirely. At least 75% of the line is drawn at closing, so it works more like a lump sum with a revolving tail. Plan the line size around what you will actually use.
What happens if I refinance my first mortgage later?
The line stays in second position. A new first loan generally requires the line holder to agree to remain behind it. Raise that with your broker before you refinance.
