The Quick Read: A home equity line becomes a first lien when nothing else is recorded ahead of it, either because the property is free and clear or because the new line pays off the existing mortgage at closing, and on an investment property the network Lendmire brokers through caps combined loan-to-value at 70% with a $500,000 maximum line. Position follows recording order, not the product name. The CLTV test counts every lien plus the full credit limit.
- A HELOC is a second mortgage only if something is already recorded ahead of it.
- On an investment property, the ceiling is 70% CLTV, with a 700 minimum credit score.
- On a primary residence or second home, 90% CLTV exists only at a 720-or-better credit profile.
- Title must sit with an individual or a revocable living trust. An LLC cannot hold it.
- A first-lien line is underwritten on personal income and credit, not on rent coverage.
Key Terms Defined
Lien position: the order in which recorded claims against a property get paid if it is sold or foreclosed.
CLTV (combined loan-to-value): all liens on the property, counted together, divided by its value.
Junior lien: a lien recorded behind another one, such as a HELOC opened after a purchase mortgage.
Subordination: a written agreement in which one lender agrees to let another lender’s lien rank ahead of its own.
Free and clear: a property with no mortgage or other recorded lien against it.
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.
How Is Lien Position Actually Decided?
Recording order decides it. The lien recorded first in the land records generally outranks the ones recorded later. The label on the loan does not matter.
A HELOC usually ends up second because it is opened after a purchase mortgage. Nothing about the product forces that. If the title is clean, a new line is first by default.
The sequence runs the same way on most files:
1. Title work shows every recorded mortgage, judgment, and lien.
2. Any mortgage being retired gets a payoff figure.
3. The payoff is paid at closing and the old lien is released.
4. The new line is recorded and takes the position the title allows.
Tax liens are the usual exception. In most states they rank ahead of other liens regardless of recording order, which is one reason title work comes first.
What Are the Three Paths Into First Position?
Two situations create a first-lien line, and a third is a variation of the second.
| Starting condition | What happens at closing | What to verify |
|---|---|---|
| Free and clear | New line records first | No stray liens on title |
| Mortgage retired by the line | Payoff and release, then line records | Payoff fits within the line |
| Mortgage paid off separately | Line records into the cleared position | Release is recorded |
If a mortgage stays in place, the new line is a second lien. That is a different product decision, covered below.
How Do First-Lien and Second-Lien Lines Compare?
The lines are structurally alike, but they behave differently in underwriting and at refinance.
| Factor | First-lien line | Second-lien line |
|---|---|---|
| Existing mortgage | Paid off or none | Stays in place |
| CLTV room | Full allowed percentage of value | Allowed percentage minus senior balance |
| Later refinance | Must be paid off or subordinated | Sits behind the senior loan |
| Rate exposure | Line is your only mortgage | Fixed first may remain |
The last row is a real tradeoff. A borrower who replaces a fixed first mortgage with a variable-priced line takes on pricing movement across the whole balance.
How Does CLTV Work on a First-Lien Line?
CLTV is every lien on the property plus the new line, divided by value. On a free-and-clear property the existing-lien portion is zero, so the line alone sets the ratio.
The line counts at its full limit, not just the drawn amount. Bankrate’s glossary describes this as the home equity version of CLTV. A large unused line still uses up room. At least 75% of a line on this network is drawn at closing, so little of it sits idle anyway.
The sizing method is simple. Take the allowed percentage of appraised value, then subtract the balance of any lien that stays. The CFPB’s HELOC booklet walks through that same subtraction, and notes that lenders also weigh income, debts, and credit history before setting the final limit.
On a first-lien line, the subtraction is often zero. That is why these lines can feel generous on paper. Credit and income, not the subtraction, become the binding tests.
What Are the CLTV Limits by Occupancy?
The ceiling depends on occupancy, and the tiers differ a lot. Investment lines are the tightest.
| Occupancy | Max CLTV | Min credit | Max line |
|---|---|---|---|
| Investment property | 70% | 700 | $500,000 |
| Second home | 90% only at 720+ | 640 | $500,000 |
| Primary residence | 90% only at 720+ | 600 | $750,000 |
Those are ceilings, not promises. Lower credit tiers step down on primary residences and second homes. A primary-residence line above $500,000 caps at 75% CLTV and needs a full appraisal. Above $500,000 is not available on investment property at all.
A market comparison helps here. Federal interagency guidance defines a high-LTV residential loan for owner-occupied 1-4 family property as one at or above 90% of appraised value, and says the lender’s loan plus all senior liens go into that math. That is a bank supervisory definition for owner-occupied homes. It is not an investor cap and not a network figure. On this network, an investment property tops out at 70% CLTV.
Because investor lines are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage. No federal rule caps CLTV on them. The limits come from lender guidelines.
Other eligibility points matter on these files:
- DTI runs up to 50%, qualified on the interest-only payment calculated on the full draw.
- Lines at or below $500,000 ordinarily use an automated valuation, though a borrower can request a full appraisal.
- Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing is variable and does not convert to fixed.
- A borrower is limited to three lines, and owners of more than 15 financed properties are not eligible.
- Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
These lines are available only in the 16 states where Lendmire offers full-service lending. That is narrower than its 41-market DSCR footprint, Washington, D.C. included. Every figure is subject to lender guidelines and a full file review.
What Does a Worked Sizing Look Like?
Run the numbers in percentages of value, for an investment property at the 70% CLTV ceiling:
| Scenario | Existing liens | Room for the line | What binds |
|---|---|---|---|
| Free and clear | 0% of value | Up to 70% | $500,000 maximum line |
| Low-balance mortgage kept | 40% of value | Up to 30% | CLTV percentage |
| Mortgage retired by the line | 60% of value | Up to 70%, with the payoff inside it | Payoff plus any cash taken |
| Nearly maxed mortgage | 68% of value | About 2% | $25,000 minimum line |
The first row shows why equity-rich investors look at first-lien lines. The last shows why a thin cushion kills a second-lien line outright.
In the third row, the new line replaces the existing mortgage and everything counts inside the same 70%. Only the remaining room is available as cash.
What Can Stop a Line From Being First?
A clean title is the whole game. Common blockers include:
- A mortgage that was paid but never formally released
- Judgment liens against the owner
- Tax liens, which can outrank everything else
- Mechanics’ liens from unpaid contractors
- HOA liens on condos and townhomes
Title work finds these before closing, and each one has to be paid or cleared. Two structural blockers sit outside the title. First, an LLC, corporation, partnership, or land trust cannot hold title on this product. Second, a property already deeded to an LLC needs a vesting change, or the investor needs a different loan.
What Happens to Position After Closing?
A first-lien line complicates future refinancing. If the line is your only lien and you later want a new first mortgage, the new lender needs first position. The line must be paid off, or its lender must sign a subordination agreement, a voluntary waiver of seniority. That consent is not guaranteed.
This matters if you later want a cash-out refinance on the same rental. Plan that exit before you take the line. Lendmire’s piece on first-lien versus second-lien CLTV rules for bank statement lines shows how position changes the math on a related product.
A lender can also freeze further draws if value falls or finances change. Treat the available balance as conditional, not permanent.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Keep the First Mortgage, Replace It, or Use a DSCR Loan?
The answer depends on the investor profile, and the flip points are clear.
| Situation | Usually the better fit |
|---|---|
| Free and clear, rent would not cover a cash-out payment | First-lien line, underwritten on personal income |
| Low-balance fixed first, modest cash need | Second-lien line that leaves the first alone |
| Property already titled in an LLC | DSCR cash-out refinance |
| Many financed properties or an entity-held portfolio | DSCR loan |
The first row is the real use case. A line is underwritten on personal income and credit, so it can work where rent coverage would not clear a cash-out refinance. The cost is personal exposure and variable pricing on the whole balance.
The DSCR route flips that. On a standard rental, a cash-out refinance tops out around 75% LTV across most of the network, with about six months of seasoning as the common expectation. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. For select programs, 1.00 is where coverage starts. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing the ratio is not the same as positive cash flow. It compares rent to the payment only, and repairs, vacancy, and management sit outside it.
A first-lien line on a clean rental is a defensible choice if you plan to hold, expect a refinance to be unnecessary, and can carry variable pricing. If you may refinance within a few years, or you hold property in entities, the DSCR path usually fits better. Lendmire’s rental HELOC vs home HELOC equity limits with a low first lien covers the equity-limit side. The complete DSCR loans guide covers the rest.
One broker-level pattern shows up often. Investors who focus on the maximum line size tend to miss the vesting rule, and a deed already in an LLC changes the whole plan.
Frequently Asked Questions
Is a HELOC always a second mortgage?
No. It is second only when another lien is recorded ahead of it. On a free-and-clear property, or when the line pays off the existing mortgage at closing, the HELOC takes first position.
Does CLTV count only what I draw?
No. Lenders generally test the full credit limit, so unused room still counts. At least 75% of a line on this network is drawn at closing in any case.
Does a higher credit score raise my CLTV ceiling on an investment property?
Not above 70%. An investment line caps at 70% CLTV with a 700 minimum, and moving from 700 to 720 does not change that ceiling. On primary residences and second homes, 90% CLTV does exist, but only at 720 or better.
Can my LLC hold title on a first-lien line?
No. Title must sit with an individual or a revocable living trust. If the property is already in an LLC, a vesting change or a DSCR cash-out refinance is the usual alternative.
Can I add another lien after closing?
It is possible, but any new lender counts your line at its full limit in its own CLTV math, and the line’s lender controls whether anything can rank ahead. Expect limited room on an investment property near the 70% ceiling.
