The Quick Read: The best first-lien HELOC program is the one that matches your occupancy, credit profile, and equity, because a first-lien line replaces any mortgage on the home and becomes the only loan against it, with the ceiling set by how the home is used and who holds title. On a primary residence, the network ceiling reaches 90% combined loan-to-value (CLTV), but only at a 720-or-better credit profile. On an investment property, the ceiling is 70% CLTV, with no tier above it.
- A first-lien line pays off any existing mortgage with its opening draw, so you give up that mortgage’s terms.
- Ceilings depend on occupancy: up to 90% CLTV on a primary residence at 720+, and 70% on an investment property.
- The borrower must hold title personally or in a revocable living trust, so an LLC-owned rental does not fit.
- Qualification runs on credit, debt-to-income (DTI), and equity, not on rent.
- A DSCR cash-out refinance is often the better tool when the property sits in an LLC or the goal is property-rent-based lender review.
What a First-Lien HELOC Actually Is
A first-lien HELOC is a revolving line of credit that sits in first position against your home, with no other mortgage ahead of it. A conventional HELOC sits second, behind the purchase or refinance mortgage. That one difference changes how the loan is built.
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.
Lien position is the order in which lenders get repaid from a sale or foreclosure. It is generally set by recording date. Note Servicing Center explains that the first-lien holder is paid in full before the second-lien holder collects anything, and that a first-lien foreclosure wipes out the junior lien.
There are two ways to end up in first position:
- Paid-off home. There is no mortgage, so the new line records first and is the only loan.
- Home with a mortgage. The line’s opening draw pays off the existing mortgage at closing, so the line takes over first position.
Because it replaces your mortgage, it behaves like a refinance plus a revolving line. Lendmire’s piece Best DSCR HELOC Program in First Lien Position on a Paid-Off Property covers the free-and-clear case in more depth.
| Factor | First-lien HELOC | Second-lien HELOC |
|---|---|---|
| Position | Only loan on the home | Behind the mortgage |
| Existing mortgage | Paid off at closing | Stays in place |
| Your current mortgage terms | Given up | Kept |
| Paid-off home | Records first automatically | Not applicable |
| Best fit | Consolidating into one loan | Preserving a low-cost mortgage |
Key Terms Defined
Lien: a legal claim against a property that secures a debt.
Lien position: the order in which creditors are repaid from sale or foreclosure proceeds.
CLTV (combined loan-to-value): all loans against the property, added together, divided by the property’s value.
Draw period: the stretch when you can borrow, repay, and borrow again, usually with interest-only payments.
Repayment period: the stretch after the draw ends, when principal and interest are due and borrowing stops.
DTI (debt-to-income): your monthly debt payments divided by your monthly income.
DSCR (debt service coverage ratio): monthly rent divided by the monthly payment, including principal, interest, taxes, insurance, and any association dues.
Subordination: an agreement that lets one lien sit behind another in priority.
How Underwriting Treats It, Step by Step
A first-lien HELOC is underwritten to you, not to the property’s rent. The lender looks at your credit, your debts, and your equity. Here is the sequence.
1. Occupancy and title. The lender first asks whether the home is your primary residence, a second home, or an investment property. That answer sets the ceiling. Title must be held by you personally or by a revocable living trust.
2. Lien position. If the home is free and clear, the line records first. If a mortgage exists, the opening draw retires it.
3. Line size. The CFPB’s HELOC booklet explains that lenders often set the limit by taking a percentage of the home’s value and subtracting the mortgage balance. On a first-lien line, the existing mortgage is inside the line, so the full CLTV cap applies to the new loan alone.
4. Credit. Across our wholesale network, the floor is 600, and each credit tier unlocks a different CLTV and line size. The score model is a single-bureau score keyed to the primary wage earner. The report must be no more than 90 days old at closing, and there are no rescores.
5. DTI. The maximum is 50%. For credit profiles from 600 to 679, the maximum is 45%. Any ratio above 45% requires a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to draw.
6. Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and you may request a full appraisal in any case. Every line above $500,000 requires a full appraisal.
7. Closing and draw. At least 75% of the line is drawn at closing. That is how the old mortgage gets paid off.
All of these figures are subject to lender guidelines and a full file review.
The Primary-Residence Matrix
| Credit profile | Max CLTV | Max line at that CLTV |
|---|---|---|
| 720+ | 90% | $500,000 |
| 700+ | 85% | $500,000 |
| 660 to 699 | 85% | $500,000 |
| 640 to 659 | 80% | $500,000 |
| 620 to 639 | 70% | $400,000 |
| 600 to 619 | 60% | $400,000 |
Primary residence at 720 carries a tradeoff. You can take up to 90% CLTV on a line up to $500,000, or a larger line up to $750,000 at a reduced 75% CLTV. The $750,000 line opens at 700 or better (720 on the longer-runway structure described below). It requires a full appraisal and works on a primary residence only.
The matrix above is for primary residences. Second homes floor at 640. Investment properties floor at 700 and cap at 70% CLTV. Never read a primary-residence figure as describing a rental.
Draw and Repayment Structures
The line has two phases. The Experian explainer on draw periods describes the usual pattern: payments are often interest-only during the draw, then principal plus interest begins after it ends. That jump is real, and it is the main planning issue with any line.
Our network offers two wholesale programs on primary residences and second homes:
- The longer-runway program: a 5-year interest-only draw followed by a 25-year fully amortizing repayment.
- The higher-leverage program: a 3-year interest-only draw followed by a 17-year fully amortizing repayment.
Investment lines use the 5-year draw and 25-year repayment structure only. Pricing floats across both the draw and the repayment period and never converts to fixed. A quoted figure always carries its own program’s structure.
Two practical details matter. First, because at least 75% is drawn at closing, most of the line carries interest from day one. The idea that you only pay on what you borrow is true in theory, but a first-lien line starts with most of the balance already borrowed. Second, the longer-runway program sets a $1,000 minimum for later draws.
State rules can change the structure. Tennessee shortens both draw structures, to 3 years with 12 years of repayment and 5 years with 10 years of repayment.
Where the General Rule Breaks
Most surprises come from a short list of edge cases.
Title held in an LLC. This is the sharpest difference from a DSCR loan. Fee simple or leasehold must be held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead.
Business bank accounts. Using business bank accounts to document income requires a 680 minimum. On a primary residence, where the floor is 600, that is a real gate. A 640 borrower qualifies for the line but cannot use business accounts.
Foreclosure history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits 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 that history entirely, regardless of age. Investment files follow the 7-and-4-year path.
Property types. Single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Modular factory-built homes are eligible on the longer-runway program only. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agriculturally zoned properties are not offered.
Exposure limits. 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.
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.
State caps. A Texas primary residence is a homestead and caps at 80% CLTV, so the higher matrix tiers never apply there. New Mexico and Ohio apply a CLTV cap that depends on the credit profile.
Availability. Lendmire arranges these lines in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than its DSCR footprint.
Freezes. An approved line is not guaranteed capital. The FTC lists examples of when a lender may freeze or reduce a line, such as a significant drop in home value or a material change in your finances. It also says that if you pay as agreed, the lender may not close the account or change the terms outside permitted situations. Those protections describe lines on a borrower’s home. Whether they reach a line on a rental depends on how the loan is classified, so ask the lender before relying on them.
Selling. Selling the home generally means paying the line off in full, and the CFPB’s consumer booklet is a good plain-language primer on how that works.
Giving up a low-cost mortgage. A first-lien line retires the mortgage you have. If that mortgage has terms you cannot replace, a second-lien line or a DSCR cash-out may serve you better.
Choosing the Best HELOC Program in First Lien Position on Your Home
No single program wins for every borrower. The best program for your situation turns on a handful of variables, and a broker who sees many wholesale lenders’ guidelines can match the file to the right one. Here is what separates a fit from a miss.
| Criterion | Why it matters |
|---|---|
| Occupancy | Sets the ceiling: 90% CLTV at 720+ on a primary residence, 70% on an investment property |
| Credit profile | Decides the CLTV tier, the line size, and whether business bank accounts can be used |
| Line size | Above $500,000 means primary residence only, a full appraisal, and a 75% CLTV cap |
| Title | Individual or revocable trust only |
| Draw structure | The 5/25 and 3/17 structures change when the payment steps up |
| Valuation | Automated at or below $500,000, unless you request a full appraisal |
| Mortgage you would give up | The line replaces it |
Some borrowers fit a first-lien line well:
- Owners of a paid-off primary residence who want one revolving loan with no second payment.
- Borrowers whose existing mortgage has terms they are happy to replace.
- Investors holding a rental personally who want standby capital for down payments or renovations.
Some borrowers should keep a second lien or look elsewhere:
- Borrowers with a low-cost mortgage they would be giving up.
- Anyone whose rental is held in an LLC.
- Borrowers with heavy DTI from many financed properties.
The following examples are modeled assumptions, not market data. Say you own a primary residence worth a round number, with a 740 score and no mortgage. The line is capped at 90% CLTV up to $500,000, or 75% CLTV for a larger line up to $750,000. You choose between more leverage and a larger line.
Now take a rental held personally, with a 710 score and an existing mortgage equal to 40% of value. The investment ceiling is 70% CLTV, so the new line has room for roughly 30% of value, and the opening draw has to retire that mortgage first. Closing costs come out of what is left.
One caution applies to rehabs. If you are tapping equity after improvements, an automated valuation may not capture the added value. Improvements may support a higher appraised value, depending on comps and underwriter review, so request a full appraisal when the work is substantial.
When a DSCR Cash-Out Is the Better Tool
If the rental sits in an LLC, or you want the property’s rent to carry the file, a DSCR cash-out refinance is the more practical route. The complete DSCR loans guide covers the full picture. 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.
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. LLC titling is possible, depending on program guidelines.
| Factor | First-lien HELOC | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Credit, DTI, equity | Rent covering the payment |
| Title | Individual or revocable trust | LLC possible, per program |
| Investment ceiling | 70% CLTV | 75% on standard rentals; 70% on short-term-rental collateral |
| Structure | Variable, draw then repayment | 30-year fixed spine; 40-year and interest-only through select lenders |
| Loan size | $25,000 to $750,000 line | Up to $3,000,000 on standard programs |
A few more DSCR figures help with the comparison. Cash-out typically expects about 6 months of seasoning. A coverage ratio of 1.00 is where many select programs start, while a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Most programs want credit around 660, with a 620 floor in parts of the network, and 700+ unlocks the strongest leverage tiers. Reserves commonly run around 6 months of PITIA (principal, interest, taxes, insurance, and association dues), and larger loans step up. These figures vary by lender, leverage, loan size, and transaction.
Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.
Frequently Asked Questions
Can I get a first-lien HELOC if I still owe on my mortgage?
Yes, on an eligible property. The opening draw pays off the existing mortgage at closing, so the line becomes the only loan. At least 75% of the line is drawn at closing, so most of it carries interest from the start. You also give up the old mortgage’s terms, which matters if those terms are hard to replace.
Can an LLC-owned rental qualify?
No, not directly. Title must be held by an individual or a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead, subject to program terms.
What credit score do I need?
The program floor is 600, and it applies to primary residences. Second homes floor at 640, and investment properties floor at 700. A line above $500,000 requires 700 or better (720 on the longer-runway program).
Do I need an appraisal?
Often not. Lines at or below $500,000 ordinarily run an automated valuation, though a higher CLTV may call for a secondary valuation. A full appraisal is required on every line above $500,000, and you can request one anytime.
Is a first-lien HELOC a DSCR product?
No. It is reviewed around credit, DTI, and equity, not on rent. A DSCR loan is reviewed for the property.
