The Quick Read: It depends on three things: the property’s value, the combined loan-to-value cap on an investment line, and every lien already on the property. On our wholesale network, an investment-property line caps at 70% combined loan-to-value (CLTV) and $500,000, subject to lender guidelines.
- The formula is value × the CLTV cap, minus every existing lien.
- Investment lines run from $25,000 to $500,000, and the 70% ceiling does not rise with a higher score.
- Credit must be 700 or better, and debt-to-income (DTI) can run up to 50%.
- The rental must be titled to you personally or to a revocable living trust, not an LLC.
- The line is available only in Lendmire’s 16 full-service states, a narrower footprint than its DSCR lending.
A property’s paper equity can sit well above what a line will release. That gap is where most of the confusion lives, so let’s close 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.
What Is the Formula for the Maximum Line?
The maximum line equals the property’s value times the CLTV cap, minus all existing liens. On an investment property in our network, the cap is 70% CLTV. The line also cannot exceed $500,000 on an investment property, whichever limit binds first.
Think in percentages. Say a rental has a first mortgage equal to 50% of its value. A 70% cap leaves room for a line of up to 20% of value. Equity of 50% sounds like a lot, but the cap and the existing lien decide the answer, not the equity itself.
Now take a rental with no mortgage. The whole 70% is available, so the dollar cap is more likely to bind. A free-and-clear rental worth well over $700,000 hits the $500,000 line limit before it hits 70% of value. A mid-priced rental with a modest first mortgage runs into the percentage cap first.
The CFPB booklet on home equity lines describes the same logic for lines in general. A lender applies a percentage to the appraised value, subtracts what you owe on the mortgage, and weighs your credit history. The booklet’s example uses 75 percent. That is an illustration for owner-occupied homes. Investment property sits lower, and our network’s investment ceiling is 70%.
| Scenario | What binds first | What it means |
|---|---|---|
| Typical equity, first mortgage in place | 70% CLTV cap | Line is the gap between 70% and your existing lien |
| Free-and-clear, moderate value | 70% CLTV cap | Whole 70% is open, up to $500,000 |
| Free-and-clear, high value | $500,000 line limit | Dollar cap binds before the percentage |
Why Is an Investment Line Capped Lower Than a Primary-Home Line?
Lenders treat a rental as a higher-risk asset, so they ask for more remaining equity. NerdWallet’s explainer on investment-property HELOCs says the lender pool is smaller, requirements are stricter, and you cannot borrow as much as against a primary home.
Our network shows the split plainly. Occupancy sets the ceiling. On an investment property, 70% CLTV is the top. On a primary residence or second home, the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile. Don’t carry the primary-home figure over to a rental. It does not apply.
Market-wide surveys of investor experience vary. Our network figure is the 70% CLTV ceiling above.
What Shrinks Your Line Below the Ceiling?
Credit, DTI, title, and valuation can all pull the usable line below the formula. This is a borrower-based product. The rent matters far less than it does on a DSCR loan.
- Credit: The minimum on an investment line is 700. Both 720 and 700 reach the same 70% CLTV, so a higher score does not buy extra leverage.
- DTI: The maximum is 50%. The lender tests the interest-only payment on the maximum draw, so a heavy personal debt load shrinks the line before equity does.
- Valuation: Lines at or below $500,000 ordinarily use an automated valuation, with no traditional appraisal. A borrower may still ask for a full appraisal.
- Property type: Single-family, 2-4 unit, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not.
- History: A bankruptcy needs four years of seasoning from discharge or dismissal. Investment files follow a seven-year path for foreclosure and four years for a deed-in-lieu, pre-foreclosure, or short sale.
Does Title or an LLC Change the Answer?
Yes, and it is the sharpest difference from a DSCR loan. The rental must be held by you as an individual or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on the line.
Picture an investor whose three duplexes sit inside an LLC. Each has strong equity. None qualifies for the line as titled. The options are a vesting change to personal name, which carries its own lender and title considerations, or a DSCR cash-out refinance instead. The cash-out path qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and it can hold LLC title depending on program guidelines.
Re-titling is not a sure fix either, because lender stipulations on rental HELOCs vary. Check each lender’s requirements before you change how the property is held.
How Many Rentals Can You Pull From?
Each line is secured by one property, and equity in one rental cannot back a line on another. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on one of our wholesale programs and $750,000 on the other. A borrower with more than 15 financed properties is not eligible.
Those two programs differ in their terms. The higher-leverage program is built for stronger credit profiles and larger combined exposure. The longer-runway program carries a lower exposure cap and a longer repayment period. On an investment line, the structure is the same either way: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing, and pricing floats through both the draw and the repayment period. It never converts to fixed.
That matters for stress-testing. A floating, interest-only draw can change your obligation without any change in the property. Stack that on top of an existing first mortgage and the combined payment deserves a hard look. The CFPB’s HELOC overview also warns that a lender may restrict further draws if the home’s value falls significantly.
HELOC or DSCR Cash-Out: Which Fits?
Choose the line when you want to keep a good first mortgage in place. Choose a DSCR cash-out when title, size, or scale push you elsewhere. The two products test different things.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Your credit, DTI, and the property | Property rent versus the payment |
| First mortgage | Stays in place | Replaced |
| Title | Individual or revocable trust | LLC possible, per program guidelines |
| Leverage | 70% CLTV ceiling, investment line | Around 75% LTV on most of our network |
| Size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
A cash-out refinance on a standard rental tops out around 75% LTV across most of our network, with about six months of seasoning the common expectation. Coverage of 1.00 is where select programs start, and stronger ratios open better pricing and leverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. A DSCR ratio compares rent to the full monthly obligation. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, and management sit outside it. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
A cash-out also replaces your existing first mortgage. If that loan has favorable terms, the line may protect them. Our complete DSCR loans guide walks through the cash-out side in full.

Frequently Asked Questions
Can I borrow more than 70% of a rental’s value on a HELOC?
Not on an investment property in our network. The ceiling is 70% CLTV, with a $500,000 line maximum. Primary residences can reach 90% CLTV, but only at a 720-or-better profile. Market-wide figures vary by lender, though the network figure is the one that applies here, subject to lender guidelines.
Does a higher credit score raise my limit?
Not on an investment line. Both 720 and 700 reach 70% CLTV, and 700 is the hard floor. A better score can help with eligibility and file strength, but it does not lift the ceiling.
Can I use a HELOC on a rental owned by my LLC?
No. The line requires title in your personal name or a revocable living trust. An LLC-held rental needs a vesting change or a DSCR cash-out refinance, subject to program terms.
Will an appraisal be required?
Often not. Because an investment line caps at $500,000, it ordinarily runs on automated valuation. You may request a full appraisal, and a higher CLTV may call for a secondary valuation.
How many rentals or lines can I hold?
Up to three lines per borrower, with combined exposure capped by program. Each line sits on one property.
