Top HELOC Providers for Borrowers Keeping a Mortgage in Place

The Quick Read: A home equity line adds a second loan behind your first mortgage, so the first loan keeps its balance, term, and payment untouched. The lenders that write these lines on rentals are a narrower group than the ones advertising lines on primary homes. Which one fits depends on occupancy, credit, title, and leverage. Lendmire is a mortgage broker, not a lender, and it places these files through select wholesale partners.

• On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score and lines up to $500,000.
• On a primary residence, the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile and up to $500,000.
• The property must be titled to you personally or to a revocable living trust. An LLC cannot hold title.
• Approval rests on your personal credit and debt-to-income ratio (DTI), not on the rent.
• If the property sits in an LLC, a DSCR cash-out refinance is usually the cleaner route.

Why a HELOC Leaves Your First Mortgage Alone

A home equity line of credit (HELOC) is a separate lien that sits behind your first mortgage. A cash-out refinance does the opposite: it pays off the first loan and replaces it. If your first loan has terms you want to keep, the line lets you borrow against equity without touching it.

The trade-off is a second payment. NerdWallet describes the typical market setup as a draw period that is interest-only and variable. It also says the lender pool for rental lines is smaller and the requirements are stricter than for a primary home.

On this network, the line can also be a standalone loan in first or second position. That matters if you own the property free and clear.

Who Writes a HELOC on a Rental?

The lenders that write rental lines depend on your situation: occupancy, credit profile, title, and how much leverage you need. Lenders that market lines for primary homes often have no rental option at all.

A broker shops several wholesale lenders and matches your file to the program that fits. Lendmire works this way for borrowers 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 41-market DSCR footprint, which covers 40 states plus Washington, D.C.

Here is what the lenders in the network look for, by occupancy. Every figure is subject to lender guidelines and full file review.

• Investment property: 70% CLTV, lines up to $500,000, minimum credit 700.
• Second home: up to 90% CLTV at 720 or better, down to 75% CLTV at a 640 profile, lines up to $500,000.
• Primary residence: up to 90% CLTV at 720 or better on lines up to $500,000. Lines above $500,000 and up to $750,000 are available only here, with a full appraisal and a cap of 75% CLTV.
• Line size: $25,000 to $750,000 overall.

Those larger primary-residence lines need a credit profile of 700 or better (720 on the longer-runway structure). On an investment line in this network, the ceiling is 70% CLTV, which leaves 30% equity.

How Underwriting Treats the Line, Step by Step

A HELOC file runs on you, not on the property’s rent. That is the reverse of a DSCR loan. Here is the sequence.

1. Occupancy is coded first. The property is flagged primary, second home, or investment. That flag picks the leverage table and the minimum credit score.

2. The equity test runs. CLTV is your first-mortgage balance plus the new line, divided by the property’s value. The room left for the line is the allowed CLTV minus what you already owe.

3. Your personal profile is reviewed. Maximum DTI is 50%, and 45% for profiles from 600 to 679, which applies only where the occupancy’s minimum score allows it (primary residences). A ratio above 45% needs a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw. The credit report can be no more than 90 days old at closing.

4. Valuation is ordered. Lines at or below $500,000 ordinarily use an automated valuation, not a traditional appraisal. A higher CLTV may require a second valuation. A full appraisal is required above $500,000, and you can request one anyway.

5. Title and vesting are checked. The deed must show you personally or your revocable living trust.

6. Documents are collected. Expect a first-mortgage statement, an insurance declarations page, the vesting deed, and credit and income paperwork.

A Worked CLTV Example

Say you own a rental, and your first mortgage equals 50% of its value. Your credit is 700. The investment-property ceiling is 70% CLTV. The line can use about 20% of the property’s value, up to the $500,000 cap.

Now take the same 50% first mortgage on your primary home at a 720 profile. The ceiling is 90% CLTV, which leaves about 40% of value. Occupancy alone changes the answer.

Run it the other way if your first mortgage is already 65% of the rental’s value. Only about 5% of value is left under the 70% ceiling. The line may be too small to bother with.

Draw and Repayment: How the Line Is Built

A line has two phases. You borrow during the draw period, then you repay. The CFPB’s HELOC explainer says you can spend up to your limit during the draw period. It also says the cost is usually variable, so payments can change month to month. Some market lines let you convert part of the balance to a fixed rate.

This network has two draw structures on primary residences and second homes:

• 3-year draw structure: a 3-year interest-only draw, then a 17-year fully amortizing repayment.
• 5-year draw structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment.

Investment lines use the 5-year draw structure only. Tennessee shortens both: 3 years then 12, and 5 years then 10.

At least 75% of the line is drawn at closing on both structures. Pricing floats through the draw and the repayment, and it never converts to fixed. After closing, the minimum subsequent draw is $1,000 on the 5-year structure (Texas: $4,000). The 3-year structure does not state a minimum.

The CFPB’s HELOC booklet recommends getting three estimates. A broker does this comparison across lenders for you.

Where the General Rule Breaks

LLC-owned rentals. This is the most common dead end. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.

Re-titling to qualify. Some investors move title into their own name for the line. Moving title can trigger the first lender’s due-on-sale clause, while simply adding a second lien generally does not. Ask your first-mortgage lender before you touch the deed.

Free-and-clear properties. With no first mortgage, there is no first-lender clause to worry about. The standalone first-lien structure fits here.

A primary home turning into a rental. Occupancy at application drives the table. A line opened while the home is still your primary residence generally sits in the primary-residence tier. A rental fits the investment tier.

Using your home’s equity to buy a rental. The collateral is the home you live in, so a struggling rental puts your residence at risk.

Exposure limits. You can hold up 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.

Property types. Eligible: single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones. Modular factory-built homes are eligible on the longer-runway program only. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.

Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. A foreclosure follows a 7-year path on one program and is declined on the other. A deed-in-lieu, pre-foreclosure, or short sale follows a 4-year path on that same program.

Texas primary homes. A Texas primary residence is a homestead and caps at 80% combined loan-to-value. Texas second homes and investment properties follow the standard tables.

Keep the First Mortgage or Refinance?

Keeping the first loan is not always the right call. The choice depends on how your situation lines up.

Setup costs also tilt the choice. Commercial Bank’s explainer notes that a HELOC typically costs less to set up than a full refinance.

When DSCR Cash-Out Is the Better Tool

A personal HELOC uses up your DTI room. That can affect later applications that look at your personal obligations. If you own many rentals, a DSCR loan may suit you better because it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Typical DSCR cash-out terms across the network run up to about 75% LTV on standard rentals, with about 6 months of seasoning common. Most programs want around a 660 score, and a 620 floor exists in parts of the network. Coverage of 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow, since repairs, vacancy, and management sit outside the calculation.

The complete DSCR loans guide covers the full picture. For investors comparing providers, Lendmire’s piece Top DSCR HELOC Providers While Keeping the Existing First Mortgage in Place is a useful next read.

Questions to Ask Any Provider

• Does this lender write lines on investment properties, and at what CLTV?
• Is the line standalone, in first position, or in second position?
• What are the draw length and repayment length?
• How much must be drawn at closing?
• Does pricing ever convert to fixed?
• Does the lender need an appraisal, or will an automated valuation do?
• Can the property sit in an LLC, or must I hold title personally?

Key Terms Defined

CLTV (combined loan-to-value): your first-mortgage balance plus the new line, divided by the property’s value.

Draw period: the window when you can borrow from the line, repay, and borrow again.

Lien position: whether a loan gets repaid first (first lien) or after another loan (second lien) if the property is sold.

DTI (debt-to-income): your monthly debt obligations divided by your monthly income.

DSCR (debt service coverage ratio): monthly rent divided by the monthly principal, interest, taxes, insurance, and any HOA dues on the property.

Vesting: how title to the property is held, such as an individual or a revocable living trust.
