Investment Property HELOC Requirements at the Maximum LTV

The Quick Read: On Lendmire’s wholesale network, a home equity line on a rental tops out at 70% combined loan-to-value. The line can reach $500,000, and the minimum credit score is 700. The lender sizes it on your personal credit and debt-to-income ratio, not on what the rent covers. All of this is subject to lender guidelines and is not a commitment to lend.

• Ceiling: 70% CLTV on an investment property, with no higher tier.
• Credit: 700 is a hard floor. Scoring 720 or more does not raise the investment ceiling.
• Line size: $25,000 to $500,000 on a rental. Lines above $500,000 are available on primary residences only.
• Title: You or a revocable living trust must hold it. An LLC cannot.
• Sizing: The lender counts every lien plus the full line limit, not the drawn balance.

What Is an Investment-Property HELOC?

An investment-property HELOC is a revolving line of credit secured by a rental you own. You borrow against the equity, which is the property’s value minus what you owe. You can draw, repay, and draw again during a set draw period.

NerdWallet notes that these lines exist but come from a smaller pool of lenders. It says you can usually borrow less than on a primary home and that requirements are strict. Multiple appraisals may be required to confirm value. That matches what the wholesale network shows: a rental line is a narrower product than a line on the house you live in.

On this network, an investment line is a standalone line in first or second lien position. It runs a 5-year interest-only draw period, then a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing. Pricing floats through both the draw and repayment periods and never converts to fixed.

This is not a DSCR loan. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC works the opposite way: it qualifies you. The rest of this piece shows what that means at the maximum leverage.

Key Terms Defined

LTV (loan-to-value): The loan balance divided by the property’s value, shown as a percentage.

CLTV (combined loan-to-value): Every lien on the property, including the full new line limit, divided by value. This is the number the cap applies to.

Line cap: The largest line a lender will write, regardless of how much equity you have. On an investment property here, that is $500,000.

Draw period: The stretch when you can borrow against the line. Repayment follows it.

Vesting: How title is held, such as in your own name, in a trust, or in an LLC.

DTI (debt-to-income ratio): Your monthly debt payments divided by your monthly income.

How Underwriting Treats the Line, Step by Step

The lender runs the same sequence on every file. Each step can stop the deal before the next one starts.

1. Property check. The collateral must be single-family, a 2-4 unit, a PUD, a townhome, or a condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial or mixed-use property, and agriculturally zoned land are not eligible. In several states the network serves (IN, NC, PA, TN, TX, and WA), a property listed for sale, or listed within the past 60 days, is also ineligible.

2. Title check. Fee simple or leasehold title must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.

3. Credit check. An investment line needs a 700 minimum. The report comes from a single-bureau score model keyed to the primary wage earner, and it must be no more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history on an investment file follows a 7-year path, with 4 years for a deed-in-lieu, pre-foreclosure, or short sale.

4. DTI check. The maximum is 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.

5. Valuation. Lines at or below $500,000 ordinarily use an automated valuation. A higher CLTV may trigger a secondary valuation, and you may request a full appraisal in any case.

6. CLTV sizing. The lender adds all existing liens to the full requested line limit and tests the total against 70% of value.

7. Exposure check. You are limited to three lines. A borrower with more than 15 financed properties is not eligible.

Notice what is missing from the list: rent. The lender does not divide your lease income by a payment. Your personal file decides.

How Much Can You Borrow at the Cap?

Use this formula: maximum line = value × 70% − existing liens. Then apply the $500,000 line cap and the $25,000 minimum line size. Whichever limit bites first sets your number.

The scenarios below use percentages of value, so you can drop in your own figures. Lendmire’s illustrative calculator can then convert them to dollars.

• Free-and-clear rental. No mortgage means the full 70% of value is available. On a modest-value property, the percentage limit binds. On a high-value property, the $500,000 line cap binds first, and extra equity goes unused.
• Mid-balance rental. Say the first mortgage equals 40% of value. Room is 70% minus 40%, which is 30% of value. The line fits comfortably unless that figure falls under the $25,000 minimum.
• Thin-room rental. Say the first mortgage equals 66% of value. Only 4% of value remains. On most properties that is below the $25,000 minimum line, so there is no product to offer.
• No-room rental. If the first mortgage sits at 70% of value or higher, the arithmetic is already negative. No line is available.

Existing home equity lines count at their full commitment, not at what you have drawn. An unused line still takes up room under the ceiling. That surprises investors who open a line “just in case” and then find they cannot add another.

Requirements at the Cap, Side by Side

An investment line is the most restricted of the three occupancy types. The network’s ceilings are tiered by occupancy.

The 90% figure exists only for primary and second-home lines at a 720-or-better credit profile. It never applies to a rental. For investment properties, 720 and 700 both reach 70%, so credit above 700 buys eligibility rather than extra leverage.

Market-wide surveys of investment-property lines show wide variation between lenders, and some report higher ceilings. Those are market figures. The network figure for an investment line is 70% CLTV.

What Moves the Number, and What Doesn’t

What moves it:

• Your existing liens. Every dollar of first mortgage reduces the room.
• The property’s value. An automated valuation that comes in low shrinks the line.
• Property type and listing status, which can make the property ineligible outright.
• Vesting. Title in the wrong name means no line at all.

What does not move it:

• A higher credit score. Once you clear 700, the ceiling stays at 70%.
• Rent. Because the line is not a DSCR product, a strong lease does not enlarge it.
• A larger draw at closing. The 75%-drawn-at-closing rule is a structure feature, not a leverage lever.
• A business bank account. The deposit analysis needs a 680 minimum, but an investment line already floors at 700, so bank-statement income is never the binding constraint.

Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.

Where the General Rule Breaks

LLC-held rentals. Many investors hold rentals in an LLC for liability reasons. That structure is the sharpest difference from a DSCR loan, because an LLC cannot hold title on an equity line. You would need to change vesting or use a DSCR cash-out refinance instead, which can close in an LLC name subject to lender program eligibility. Moving title can trigger the first mortgage’s due-on-sale clause, while adding a junior lien generally does not. Check the first lender’s note and speak with an attorney before moving anything.

Heavy first mortgage. As the scenarios show, a first mortgage near the ceiling leaves little or nothing. A small remainder falls under the minimum line size.

The convert-later workaround. BiggerPockets describes investors opening a HELOC while a property is still their home, then renting it out later. The same piece says many banks will not lend on rentals that still carry a mortgage. Check each lender’s occupancy-change terms before you rely on this.

Heavy portfolios. The three-line limit and the 15-property cutoff bite investors who have already used home equity widely. Lendmire brokers through select wholesale partners, and the combined exposure cap depends on which program the line is placed with: $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. Rental lines follow the 5-year draw and 25-year repayment structure only.

Variable pricing and the risk of default. The CFPB describes a HELOC as an open-end line with a draw period followed by repayment, and warns that you could lose the home if you cannot repay. On a rental, the property is the rental. Payments also move with your balance and the line’s floating pricing, so a heavy draw can raise your obligation after the fact.

Selling the property. The CFPB’s HELOC brochure says a HELOC is generally payable in full when you sell. Plan for the payoff in your exit math.

Availability. Lendmire arranges these equity 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 of 41 markets, including Washington, D.C. New Mexico and Ohio also apply a CLTV cap that depends on the credit profile.

HELOC, DSCR Cash-Out, or Your Own Home’s Line?

Pick the product that matches what you have: equity, rent coverage, or a clean personal file.

Here is a simple decision rule. If your credit and DTI are strong, you want to keep the first mortgage, and the property is in your name, a HELOC fits. If you hold many properties, carry a high DTI, or own through an LLC, the DSCR route usually fits better. On a cash-out refinance, the ceiling is around 75% LTV on a standard rental and 70% on short-term-rental collateral. Coverage of 1.00 is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

Clearing 1.00 does not mean positive cash flow. DSCR compares rent to the full monthly housing payment only. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.

Before You Apply: A Checklist

Run through these items first. Each one removes a common stopping point.

• Confirm your credit score is 700 or higher, and check that no bankruptcy or foreclosure falls inside the seasoning windows.
• Pull your current first-mortgage balance and any existing lines at their full commitments.
• Estimate value and test your total liens against 70% of it.
• Confirm that title is in your name or a revocable living trust.
• Confirm the property type is eligible and has not been listed for sale in the past 60 days where that rule applies.
• Count your financed properties and existing lines against the 15-property and three-line limits.
• Gather a current first-mortgage statement, an insurance declaration, and the vesting deed.
