Top HELOC Providers Keeping Your Current First Mortgage

The Quick Read: A HELOC can sit behind your current first mortgage without touching it, but which lenders write one depends on occupancy, credit profile, title, and how much combined leverage you need, and a broker matching your file to a wholesale program is often the practical way to find a fit. Your first loan keeps its balance, term, and payment. The new line is a separate loan recorded behind it, or in first position if the property has no mortgage.

• 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.
• Primary-residence and second-home lines can reach 90% CLTV, and only at a 720-or-better credit profile. Lower credit tiers carry lower ceilings, and state rules can lower them further, as with Texas homestead properties, which cap at 80% CLTV.
• Qualification runs on your personal credit, income, and debt-to-income ratio, not on the rent the property earns.
• Title must be held by you personally or by a revocable living trust. An LLC cannot hold title on these lines.
• Lendmire arranges these lines in 16 full-service states, a narrower footprint than its DSCR lending.

Why the Provider Question Has No Single Answer

The right provider depends on your property, your credit, and your title, so no fixed ranking holds for every borrower. NerdWallet notes that the pool of lenders for rental-property lines is smaller than for primary homes, and that borrowing limits run lower because lenders see higher default risk.

That shrinks the real question. You are less likely to be choosing among many equal options than finding the few programs that write your type of property at your leverage. Lendmire is a mortgage broker, not a lender. It works with a network of wholesale HELOC lenders and matches a scenario to the program whose guidelines fit it.

Lender types differ in useful ways. Each wholesale program sets its own guidelines by occupancy, and a broker can read several sets side by side, so you avoid applying at one desk after another.

How a Line Sits Beside Your First Mortgage

Your first mortgage is not refinanced, repriced, or paid off. When the property already has a mortgage, the line typically is a second lien: a separate loan with its own terms, and you pay both. The Consumer Financial Protection Bureau (CFPB) describes a HELOC taken on a home that already has a mortgage as a second mortgage that you pay in addition to the first.

Two practical points follow.

First, the interest rate on your first loan does not change how much you can borrow. Only the first loan’s balance and the property’s value matter. A cheaper first mortgage does not create extra room, but a smaller balance does.

Second, the lien position can vary. The network writes standalone lines in first or second position. If a rental is owned free and clear, the line can be the only loan on the property, and it sits in first position.

How Underwriting Treats the Line, Step by Step

Underwriting on these lines is personal, not property-based. Here is the sequence a wholesale program typically follows.

1. Occupancy and property type are screened first. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not offered. Modular factory-built homes are eligible under the 5-year-draw structure only. Two-to-four-unit properties need a 640 minimum score under that same structure.

2. Title is checked. The borrower must be an individual or an inter vivos revocable living trust. Irrevocable, blind, and land trusts cannot hold title.

3. Value is established. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal, though a higher CLTV can trigger a secondary valuation. Every line above $500,000 requires a full appraisal, and a borrower may request one in any case.

4. The CLTV ceiling is applied. The maximum line is value times the allowed ceiling, minus every lien already on the property. The CFPB’s HELOC booklet describes the same logic: the lender sets a percentage of value, then subtracts the mortgage balance.

5. Credit is reviewed. The program reads a single-bureau score tied to the primary wage earner. The report can be no more than 90 days old at closing, and no rescores are allowed.

6. Debt-to-income is tested. The maximum is 50%. Profiles from 600 to 679 are held to 45%, and any ratio above 45% requires a 680 minimum. The payment is qualified as interest-only on the maximum draw, not on what you plan to borrow.

Rental income does not drive this process. Rent coverage is the DSCR model, a different product covered below.

What the Ceilings Look Like by Occupancy

The ceiling depends on how the property is used, so any single number quoted for “a HELOC” is misleading. These are the network’s guideline figures, and each is subject to lender guidelines and full file review.

On an investment property, 70% is the ceiling at both the 700 and 720 tiers. Market surveys differ: Experian reports investment-property lines commonly capped near 80% of value. That is a market-wide figure. On this network, an investment line tops out at 70% CLTV.

A line above $500,000 is available on primary residences only. It requires a credit profile of 700 or better (720 on the longer-runway 5-year-draw structure), caps at 75% CLTV, and requires a full appraisal. The standard minimum line is $25,000.

A Worked CLTV Example

The math below uses shares of property value so you can apply it to your own numbers. It is an illustration of how the ceiling works, not a quote.

The second row shows a common snag. Five percent of value on a modest property may fall below the $25,000 minimum line, so the file may not work at all. The third row is capped by the maximum line and the credit tier, so the full 30% may not be available.

The line is also sized at its limit, not the amount drawn. Your first mortgage payment still counts in your debt-to-income ratio, and the line is qualified on the interest-only payment at the maximum draw.

Structures and Variations Worth Knowing

The network offers two draw structures on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other, the 5-year-draw structure, has a 5-year interest-only draw followed by a 25-year repayment. Tennessee shortens both. Investment lines run the 5-year-draw structure only.

Four features matter before you apply.

• At least 75% of the line is drawn at closing. That differs from a classic line where you borrow only when needed.
• Pricing floats through both the draw and repayment periods and never converts to fixed, so you cannot lock a portion of the balance.
• After closing, subsequent draws carry a $1,000 minimum on the longer-runway structure, with Texas at $4,000.
• A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage structure and $750,000 on the longer-runway one. A borrower with more than 15 financed properties is not eligible.

Both structures are standalone lines in first or second lien position, and each carries its own draw and repayment terms, so any quoted figure should be read alongside the structure it belongs to.

Where the General Rule Breaks

The standard path assumes an individual owner, a standard property, and a clean credit history. Several situations break that assumption.

LLC title. An LLC, corporation, or partnership cannot hold title on these lines. If your rental is already deeded to an LLC, you need a vesting change or a different product. This is the sharpest structural difference from a DSCR loan, which can be made to an LLC subject to lender program eligibility.

Home converted into a rental. An owner-occupied line may carry terms that restrict renting the property. The line’s occupancy rules apply to the property as used, so a primary-residence line is the wrong tool for a home you plan to rent out.

Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history splits by program. One structure seasons a foreclosure in 7 years and a deed-in-lieu, pre-foreclosure, or short sale in 4. The other declines the history entirely. Investment files follow the 7-and-4-year path.

Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.

Texas primary residences. A Texas primary is a homestead and caps at 80% combined loan-to-value, along with a 12-day waiting period, a one-lien-at-a-time rule, and 12-month seasoning. Second homes and investment properties are eligible as non-homestead transactions. Texas properties are limited to 10 acres.

New Mexico and Ohio. Both apply a CLTV cap that depends on the credit profile.

Geography. These lines are available only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.

Keep the First Mortgage or Replace It?

Keeping the first mortgage is a good choice when its terms are favorable and you need a modest amount of new money. A cash-out refinance reprices your entire balance, while a line reprices only the new money. The tradeoff is cost: a very favorable first loan paired with a pricier second can cost more overall than one blended refinance, so the comparison belongs on blended cost, not on each loan alone.

Property-rent-based lender review is the usual pivot when a personal-income file does not work. A DSCR cash-out qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. On standard rentals, cash-out tops out around 75% LTV, while short-term-rental collateral caps at 70%, with about 6 months of seasoning as the common expectation. Coverage of 1.00 is where select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Lendmire arranges DSCR investor loans through select lenders in 41 markets, including Washington, D.C. For a deeper explanation, see the complete DSCR loans guide.

A cash-out replaces your first mortgage, so it only makes sense if the old loan has no special advantage.

A Pre-Application Checklist

Run through these before applying anywhere.

1. Confirm occupancy, because it sets your ceiling. 2. Confirm how title is held. If an LLC owns the property, plan for a vesting change or a different product. 3. Estimate your first mortgage balance as a share of value, then subtract it from the ceiling. 4. Check whether the remaining room clears the $25,000 minimum line. 5. Pull your credit and check the score tier against the table above. 6. Calculate your debt-to-income ratio, including the first mortgage payment and the interest-only payment on the full line. 7. Confirm the property type is eligible and is not listed for sale. 8. Decide what the funds are for. A down payment funded with borrowed money is a separate question the purchase lender must approve.

Key Terms Defined

CLTV (combined loan-to-value): The total of all loans secured by the property, divided by its value.

Second lien: A loan recorded behind your first mortgage, which is paid second if the property is sold or foreclosed.

Draw period: The stretch during which you can borrow against the line, usually with interest-only payments.

Repayment period: The stretch after the draw ends, when you repay principal and interest over a fixed schedule.

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

DSCR (debt service coverage ratio): Monthly rent divided by the full monthly payment on the property, used to qualify rental loans.
