The Quick Read: The line equals the home’s value times the lender’s CLTV cap, minus existing liens, and a paid-off home has no liens to subtract. On an investment property in Lendmire’s network, that cap is 70% CLTV with a $500,000 maximum line, subject to lender guidelines.
- A home equity line of credit (HELOC) lets you borrow against your home, draw as needed, and repay over time.
- Equity is not borrowing capacity. The cap leaves a slice of value untouched.
- On an investment property, the network ceiling is 70% CLTV, with a 700 minimum credit score.
- On a primary residence or second home, the ceiling reaches 90% CLTV only at a 720-or-better credit profile.
- A dollar cap can bind before the percentage does.
Owning a rental outright feels like holding a full vault. It isn’t. The lender decides how much of that value it will lend against, and the answer changes with how you use the property. This walkthrough shows the math, the tests that shrink the number, and where a HELOC stops making sense.
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.
Key Terms Defined
Free and clear. You own the property with no mortgage or other loan secured by it.
Equity. The home’s value minus what you owe on it. A paid-off home’s equity equals its full value.
CLTV (combined loan-to-value). All loans secured by the property, including the new line at its full limit, divided by the property’s value.
First lien. The loan with first claim on the property if it is sold to repay debt. On a free-and-clear home, a new HELOC can take that position.
Draw period. The stretch when you can borrow from the line. Repayment follows it.
Release. The recorded document that clears an old loan from the title.
Can You Get a HELOC With No Mortgage?
Yes, and it is often the simplest version of the product. A standalone line can sit in first or second lien position, so a paid-off home can carry a HELOC as its only loan.
Nothing is in front of the line, so nothing is subtracted before the cap applies. That is the whole advantage of free and clear: the entire CLTV percentage is available as a starting ceiling. “Starting” matters, because several other tests can pull the final number lower.
The Sizing Formula, Step by Step
The maximum line is value times the CLTV cap, minus existing liens. Work through it in this order.
1. Establish the value. Lines at or below $500,000 ordinarily run on an automated valuation instead of a traditional appraisal. A higher CLTV may require a second valuation. You can also request a full appraisal.
2. Find the cap for your occupancy. The cap depends on whether the home is an investment property, a second home or your primary residence. It also depends on your credit tier.
3. Multiply value by the cap. For an investment property, that means 70% of value.
4. Subtract existing liens. Free and clear means zero. A tax lien or an unreleased old mortgage still counts, though.
5. Apply the dollar cap. The smaller of the percentage result and the program’s maximum line wins.
6. Run the borrower tests. Credit, debt-to-income and property type can still lower or stop the line.
The new line counts at its full limit, not just the amount you draw. A line you leave undrawn still uses up leverage room.
Where the Ceilings Land by Occupancy
Ceilings are tiered by occupancy and credit score. A HELOC on a rental does not work like one on your own house. NerdWallet notes that rental lines come from a smaller pool of lenders and generally allow less borrowing than lines on a primary home.
Market surveys report that many lenders cap equity lines around 85% CLTV, per Experian. That is a market-wide figure. Across Lendmire’s wholesale network, the numbers are narrower:
| Occupancy and credit | Max CLTV | Max line |
|---|---|---|
| Investment, 700+ | 70% | $500,000 |
| Second home, 720+ | 90% | $500,000 |
| Primary, 720+ | 90% | $500,000 |
| Primary, 700+ | 75% | $750,000 |
Those are the top tiers. Lower credit tiers on primary residences and second homes step the cap down, and an investment property has no tier above 70%. No tier on the network puts an investment line above $500,000 in total. A line above $500,000 is primary-residence only. It caps at 75% CLTV and requires a full appraisal.
Worked Examples
The calculator on this site can convert these percentages to dollars as an illustrative estimate. Here is the logic.
Example one: the percentage binds. Take a free-and-clear rental of modest value and a 700-plus credit score. The line is 70% of value minus zero. The result sits under the $500,000 maximum, so the percentage wins.
Example two: the dollar cap binds. Take a rental worth enough that 70% of its value exceeds $500,000. The percentage no longer matters. The line stops at the $500,000 maximum, and the owner leaves more equity untouched than the 30% cushion implies.
Example three: a lower valuation. Say the automated valuation comes in 10% below what you expected. The ceiling falls by the same 10%, because the cap multiplies the lower value. A softer valuation shrinks the line directly.
Example four: the same home with a first mortgage. Say a first mortgage equals 45% of the home’s value. Under a 70% investment cap, only about 25% of value remains for a new line. The same home free and clear offers the full 70%. Paying off the mortgage first buys you the most room.
Why Equity Is Not Borrowing Capacity
Equity is value minus debt. Borrowing capacity is a lender’s formula. The CFPB defines equity as the home’s value minus what you owe, and describes a HELOC as an open-end line you can borrow against repeatedly. Nothing in that definition promises you the whole figure. The cap, the dollar limit and your profile set the number.
A paid-off home does not mean approval is automatic either. Credit, income and valuation can still affect the outcome.
What Shrinks the Line From the Ceiling
Once the formula gives you a ceiling, these tests can lower it.
- Credit. Investment lines require at least a 700 score. Primary residences start lower, at 600, with steeper caps at lower tiers. The network uses a single-bureau score keyed to the primary wage earner, on a report no more than 90 days old at closing.
- Debt-to-income. The maximum is 50%, and 45% for scores from 600 to 679. A ratio above 45% requires a 680 minimum. The test runs on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
- Property type. Single-family, 2-4 units, PUDs, townhomes and condominiums are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural zoning are not.
- Exposure. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
- Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history is treated differently by program on primary residences and second homes.
Availability is also narrower than the DSCR footprint. These lines are offered only in Lendmire’s 16 full-service states, while DSCR investor loans run across 41 markets, including Washington, D.C.
Title and Old Liens
A free-and-clear home can still carry hidden claims. A paid-off mortgage that was never released, an unpaid tax lien or an association claim can all show up in the title search. Any of them can keep a new line from recording in the lien position it needs, or reduce it dollar for dollar.
Vesting is the sharper issue. These lines require title held by you personally or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead, subject to lender program eligibility.
How Much of the Line Should You Actually Use?
Use less than the ceiling. At least 75% of the line is drawn at closing, so this is not an open safety net you leave untouched. Plan on a mostly drawn line from day one. After closing, the minimum subsequent draw is $1,000, except in Texas, where it is $4,000.
Investment lines follow one structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment. Pricing floats during both stages and never converts to fixed. The risk shows up when the draw ends. A payment that was interest-only starts paying down principal, and the variable pricing can move at the same time.
Three habits protect you:
- Size the draw to what the project needs, not what the ceiling allows.
- Test the repayment-stage payment against your rents before you borrow.
- Leave a cushion of equity, since the lender can freeze or reduce a line if values fall or finances worsen, per the CFPB’s HELOC booklet.
The same booklet warns that renting your home to others may be prohibited under a line’s terms. On a rental, that is expected. Read the covenants before you sign.
HELOC or DSCR Cash-Out for a Paid-Off Rental?
The two products read different things. A HELOC underwrites you: credit and debt-to-income. A DSCR cash-out refinance reviews the property’s rental income: it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR is rent divided by the full monthly obligation: principal, interest, taxes, insurance and any association dues.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| What is underwritten | Borrower credit and DTI | Rent against payment |
| Typical ceiling | 70% CLTV | Around 75% LTV |
| Structure | Variable, interest-only draw | 30-year fixed is the spine |
| Title | Individual or revocable trust | LLC possible, per program terms |
DSCR cash-out has its own tests. Most files want about 6 months of seasoning, and a score near 660 or better opens more programs. For reserves, a common expectation is about 6 months of PITIA (principal, interest, taxes, insurance and any association dues). Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). A coverage of 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing that number is not the same as positive cash flow, because repairs, vacancy, management and capex sit outside the calculation.

What the Investor Decision Looks Like
Many investors use a HELOC on a paid-off rental to fund the next purchase, then refinance the new property to repay it. BiggerPockets discusses this pattern: HELOC money first, then a DSCR or cash-out refinance on the acquired property. It works when the exit is clear. Without one, you end up holding two loans.
A HELOC suits you when:
- You hold title personally or in a revocable trust.
- Your credit is 700 or better and your debt-to-income is low.
- You want interest-only flexibility and can tolerate variable pricing.
- The need is short-term.
A DSCR cash-out suits you better when:
- The rental sits in an LLC.
- You want a fixed structure and a longer hold.
- Your personal debt-to-income is stretched but the rent coverage is strong.
The HELOC also adds a variable-rate obligation that appears in your personal debt-to-income, which can affect later approvals. 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.
Frequently Asked Questions
Can I borrow 100% of my home’s value with a HELOC?
No. The network’s ceiling is 70% CLTV on an investment property. On a primary residence or second home, it reaches 90% only with a 720-or-better credit profile. The remainder stays as your equity cushion.
Does a paid-off home guarantee a larger line?
It gives you the most room under the cap, because no existing lien is subtracted. It does not guarantee approval or the full ceiling. Credit, debt-to-income, valuation, title and property type still apply, and every file is subject to lender guidelines and full review.
Can my rental be held in an LLC?
Not for this product. LLCs, corporations and partnerships cannot hold title on these lines. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance can be reviewed instead, subject to program terms.
What if the valuation comes in low?
The line shrinks in step with the value. Lines at or below $500,000 ordinarily run on an automated valuation, and you can request a full appraisal if you think the number is off.
Should I leave part of the line undrawn?
At least 75% of the line is drawn at closing, so plan the size carefully. Borrow what the project requires, and keep reserves for the stage when repayment begins.
