The Quick Read: A first-lien HELOC is a revolving line of credit that sits as the only mortgage on a property, either because the home is owned free and clear or because the line pays off the existing mortgage, and the lenders that write one depend on your occupancy type, credit profile, title vesting, and how much combined leverage you need. Lendmire is a mortgage broker, not a lender. It shops a network of wholesale HELOC lenders and matches the file to the program that fits.
- A first-lien line is first among mortgages, not necessarily first among every claim on the property.
- Which lenders write these lines depends on whether the property is your residence or a rental, and many large banks do not write lines on rentals at all.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), and a 700 credit profile is the floor.
- The line is judged on your credit and debt-to-income, not on the property’s rent. That is the sharpest difference from a DSCR loan.
- LLC-owned property cannot hold title on these lines, so a deed change or a different loan type may be needed.
What a First-Lien HELOC Actually Is
A home equity line of credit (HELOC) lets you borrow, repay, and borrow again against your equity up to a set limit. “First lien” describes where the line ranks among the loans recorded against the property. If the home has no mortgage, the new line goes first. If a mortgage exists, the line pays it off at closing and becomes the only loan.
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.
Position is mostly a matter of recording order. Nolo’s lien-priority guide explains that priority decides who gets paid first after a foreclosure sale, and that the loan recorded first generally ranks first. The same guide notes exceptions. Some liens, such as certain HOA and mechanic’s liens, carry statutory priority regardless of date. Nolo’s subordination explainer adds that property tax liens override recording order.
So the accurate phrase is first among mortgages. A tax lien can still rank ahead of you.
Lenders also measure leverage with CLTV. That is the total of all loans against the property divided by its value. On a first-lien line, CLTV is simply the line limit against value, since the line pays off any existing mortgage and becomes the only loan.
Why a Ranked Provider List Would Mislead You
A single list of top providers cannot answer this question, because the right lender depends on the property and the borrower. A line on your owner-occupied home and a line on a rental go to different lenders with different rules. Many large banks simply do not write lines on non-owner-occupied property. Credit unions and regional lenders vary widely, and some will not write a first-position line on a rental under the HELOC label at all.
That is where a broker earns its place. Lendmire works with a network of wholesale HELOC lenders. It looks at your occupancy, credit, vesting, and leverage need, then places the file with the program whose rules match. The best program for your situation is the one whose limits you clear, not the one with the longest brochure.
The table below shows how the three structures that investors usually compare differ:
| Factor | First-lien HELOC | Second-lien HELOC | DSCR cash-out loan |
|---|---|---|---|
| Position | Only mortgage | Behind existing mortgage | New first mortgage |
| Existing mortgage | Paid off at closing | Stays in place | Paid off at closing |
| Judged on | Credit and DTI | Credit and DTI | Property rent vs. payment |
| Access | Revolving line | Revolving line | One lump sum |
| LLC title | Not allowed | Not allowed | Subject to lender program eligibility |
How Underwriting Treats a First-Lien Line, Step by Step
Underwriting a first-lien line runs in a clear order. Each step can end the file, so the order matters.
Step 1: The lien picture. A title search shows what is recorded against the property. A paid-off home goes straight to first position. If a mortgage exists, the line must be large enough to retire it, and the payoff comes out of the opening draw. Across the network, at least 75% of the line is drawn at closing, so the payoff and any additional cash both come from that opening draw, and the rest of the limit stays available for later draws.
Step 2: Occupancy. The lender asks whether the property is your primary residence, a second home, or an investment property. This one answer sets the credit floor and the leverage ceiling, as the table in the next section shows.
Step 3: Credit. Programs in the network use 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. Bankruptcy needs 4 years of seasoning from discharge or dismissal.
Step 4: Debt-to-income (DTI). DTI compares your monthly debts to your monthly income. The maximum is 50%, and it drops to 45% for credit profiles from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. A line sized big and drawn small is still underwritten as if fully drawn.
Step 5: Valuation. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal, though a higher CLTV can trigger a second valuation. Every line above $500,000 requires a full appraisal, and you can request one in any case. An automated valuation will not capture value you plan to add through rehab.
Step 6: Title and vesting. The property must be held by you personally or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
Step 7: Closing and recording. The recorder’s stamp sets priority, not the signing date. Once recorded, the line stays on title until it is formally closed and released.
After closing, the CFPB’s HELOC booklet notes that a lender may reduce your credit line if the home’s value falls. The booklet also explains that the credit limit is set as a percentage of the home’s value less what you owe. Plan around a limit that can shrink.
What the Network’s Programs Look Like
The higher-leverage program uses a 3-year interest-only draw followed by a 17-year repayment. Investment lines run only on the 5-year draw and 25-year repayment structure. Pricing floats during both the draw and repayment periods and never converts to fixed. Each figure below applies within its own program’s terms and is subject to lender guidelines.
| Occupancy | Max CLTV | Credit and line size |
|---|---|---|
| Primary residence | 90% | 720+, up to $500,000 |
| Primary residence | 75% | 700+ (720 on the longer-runway program), up to $750,000, full appraisal |
| Second home | Up to 90% | 720+ for the top tier; 640 floor |
| Investment property | 70% | 700 floor; line up to $500,000 |
Two points matter for investors. First, the 90% figure exists only at a 720-or-better credit profile, and it never applies to an investment property. On an investment line, 70% CLTV is the ceiling with no higher tier. Second, any line above $500,000 is for a primary residence only. It requires a 700 credit profile or better (720 on the longer-runway program), caps at 75% CLTV, and needs a full appraisal.
Eligible property types include single-family homes, 2-4 unit properties (a 640 minimum applies on the longer-runway program), PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. A borrower can hold up to three lines, and anyone with more than 15 financed properties is not eligible. Availability covers Lendmire’s 16 full-service states only, which is narrower than its DSCR footprint.
Where the General Rule Breaks
An existing HELOC and a later refinance. Say you already hold a first-position line and later refinance your home. The new first-mortgage lender needs your line’s lender to sign a subordination agreement, or the old line becomes the senior lien. The line’s lender decides whether to sign. A zero balance does not remove the lien, so a line you stopped using can still block a refinance until it is closed and released.
Subordination changes priority only. It does not change your line’s terms. And an unrecorded subordination may not change priority at all.
LLC-owned rentals. An investor whose property is deeded to an LLC cannot use these lines. The fix is a vesting change into your personal name or revocable trust, or a different loan type. A DSCR cash-out loan can be placed on LLC-held property, subject to lender program eligibility.
Fourplex or small multifamily. Properties with 2-4 units are eligible in the network, but a 640 minimum applies on the longer-runway program. Many banks that do lend on a rental stop at one unit.
Rental use of the home. A line on your primary residence can carry terms that restrict renting out the property. Read the agreement before you convert a primary home to a rental.
Recently listed properties. A property listed for sale, or listed in the past 60 days, is ineligible in several states in the network.
Foreclosure-family history. Programs split here. 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 program declines that history regardless of age. Investment files follow the 7-and-4-year path.
Key Terms Defined
Draw period: the opening stretch when you can borrow from the line and pay interest only.
Repayment period: the stretch after the draw ends, when the balance amortizes fully and the line stops revolving. The CFPB’s HELOC overview says lenders often set this schedule over 10 or 20 years, and it warns that falling behind can cost you the home.
Subordination agreement: a voluntary agreement in which a lienholder agrees to rank behind a later loan.
Vesting: the legal name or entity that holds title to the property.
Debt-to-income (DTI): your monthly debt payments as a share of your monthly income.
Lien priority: the order in which recorded claims get paid if the property is sold at foreclosure.
What the Investor Decision Looks Like in Practice
Picture an investor who owns a rental free and clear in their own name and wants capital for the next purchase. A first-lien line can work if they plan to repay within a year or two, as in a buy-rehab-rent-refinance sequence. Longer-term use is harder to justify because the pricing floats and the draw period ends.
The leverage ceiling is the other constraint. On an investment property, the network stops at 70% CLTV on a first-lien line. A DSCR 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. The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. That also matters if your personal DTI is stretched.
Do not confuse the two tests, though. Clearing 1.00 coverage covers rent against the payment only. It does not account for repairs, vacancy, management, or capex. The complete DSCR loans guide walks through how that math works.
If the property is a rental and your existing mortgage is a keeper, a line may not need to sit in first position at all. If you already hold or plan a DSCR first mortgage, see Lendmire’s article Top Investment Property HELOC Providers Behind a DSCR First Lien.
Questions to Ask Any Lender Before You Apply
- Is the line truly in first position, and does the document say so?
- Does the program write lines on my occupancy type and unit count?
- Will the lender accept my vesting, or do I need a deed change first?
- What CLTV ceiling applies to my occupancy and credit tier?
- How much must I draw at closing, and what is the minimum for later draws?
- When does the draw period end, and what does repayment look like afterward?
- Can the lender reduce or freeze the line if value falls?
- Will the lender sign a subordination later if I refinance?
Frequently Asked Questions
Can I get a first-lien HELOC on a paid-off rental?
Yes, in many cases, if you hold title personally or in a revocable living trust and clear the program’s credit floor. On an investment property, the network floor is a 700 credit profile and the ceiling is 70% CLTV on a line up to $500,000. Lines on LLC-owned property are not available.
Can a first-lien HELOC replace my current mortgage?
Yes. The line pays off the existing mortgage at closing and becomes the only loan. The payoff comes out of the opening draw, and the network requires at least 75% of the line to be drawn at closing, so any limit left over stays available for later draws. Because the line’s pricing floats and never converts to fixed, compare that against the loan you would be giving up.
Does a first-lien HELOC always rank first?
It ranks first among mortgages, but not necessarily among every claim. Nolo notes that some HOA and mechanic’s liens can carry statutory priority, and property tax liens override recording order.
Which lenders write these lines?
It depends on the property, the occupancy, your credit profile, and your vesting. Because many large banks decline rentals altogether, a broker that shops several wholesale lenders can match your file to a program that accepts it. Lendmire arranges these lines through that network in 16 full-service states.
What if my credit is under 700?
On a primary residence, the program floor is a 600 credit profile, and leverage tiers step down as scores fall. For example, a 640 profile is limited to 80% CLTV on a line up to $500,000. A 640 borrower can qualify for the line but cannot use business bank accounts for deposit analysis, because that requires a 680 minimum. Investment-property lines require 700.
