Banks That Offer a HELOC When You Want to Keep a Locked-in Mortgage

The Quick Read: Banks and lenders can write a HELOC as a second lien behind your current mortgage, so the first loan keeps its rate, balance, and maturity. Which lenders do this depends on the property, the title, and the borrower. Lendmire is a mortgage broker that shops a wholesale network of HELOC lenders and matches the file to a program.

• A HELOC sits behind the first mortgage and leaves it untouched. A cash-out refinance replaces the whole loan.
• Investment-property lines come from a smaller pool of lenders, and the network ceiling on an investment line is 70% CLTV.
• Title is the sharpest filter, and it is covered in detail below.
• The line is variable-rate and interest-only during the draw, so plan for the payment to change.
• A DSCR cash-out refinance is reviewed on property income, but it replaces the first mortgage and gives up the locked-in rate.

Lendmire’s HELOC lender network operates 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. All figures below are subject to lender guidelines and full file review. None is a commitment to lend.

Why Does a HELOC Keep the Locked-in Mortgage?

A HELOC is a separate loan secured by the same property. It does not pay off or modify the first mortgage. The first loan keeps its original terms, and the new line carries its own pricing only on the amount you draw.

A cash-out refinance works the other way. It replaces the full balance with a new loan at today’s pricing, not just the cash you pull out. CBS News quotes an Urban Institute fellow making this point: a borrower with a low-rate mortgage may prefer a HELOC because the first mortgage stays in place and only the incremental funds are borrowed.

The CFPB describes a HELOC as an open-end line of credit you can borrow against repeatedly. It also notes these lines usually carry variable pricing. That matters for the trade-off. Your first mortgage stays fixed, but the line does not.

Key Terms Defined

First lien: The loan with priority claim on the property if it is sold or foreclosed.

Second lien: A loan recorded behind the first lien. A HELOC often sits here.

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

Draw period: The stretch when you can borrow, repay, and borrow again, usually paying interest only.

Repayment period: The stretch after the draw ends, when the balance amortizes and payments rise.

DSCR (debt service coverage ratio): Monthly rent divided by the full monthly housing payment on a property. DSCR loans use it instead of personal income.

Which Banks Offer This, and Who Decides?

The lenders that write this depend on the property, the title, and the borrower. Large retail banks and depository institutions mostly lend on primary homes. Investment-property lines come from a smaller group. NerdWallet says you may face a smaller pool of lenders and borrow less than you could against a primary home. It also says not every lender offers these lines.

Lendmire does not rank or recommend a single institution. It is a broker. It works with a nationwide network of wholesale HELOC lenders and places the file with the program that fits. The right program for your situation turns on five things:

• Occupancy: primary residence, second home, or investment property.
• Credit profile and debt-to-income.
• How much combined leverage you need.
• How the property is titled.
• How many properties and lines you already carry.

A broker shopping multiple lenders can compare these filters side by side. A single bank can only tell you whether you fit its one box.

How Underwriting Treats a Rental-Property Line

Here is how a rental-property file moves, step by step.

1. Lien position. The line is recorded as a first or second lien. Behind a locked-in first mortgage, it is a second lien. The first loan is not touched.

2. Title check. The borrower must hold title individually or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these programs.

3. Equity test. The lender adds the first mortgage balance to the requested line and measures it against value. On an investment property, the ceiling is 70% CLTV on the network, for credit profiles of 700 or better. Market surveys report 75%-80% for investment-property lines at some lenders. That is a market-wide figure, not available through this network.

4. Borrower underwriting. HELOC underwriting looks at the borrower’s credit and debt-to-income. Debt-to-income tops out at 50%. Because the investment line requires a 700 minimum credit profile, the lower 45% limit for profiles from 600 to 679 does not come into play on these files. Rental income may count, but the file is not a DSCR file. It is reviewed on the borrower, not on the property’s rent alone.

5. Valuation. Lines at or below $500,000 usually run an automated valuation with no traditional appraisal, though higher CLTV may require a secondary valuation. A borrower can ask for a full appraisal in any case.

6. Draw and repay. An investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Most of the line must be taken at closing, since at least 75% is drawn then, and later draws are possible after that. Pricing floats through both periods and never converts to fixed.

7. Senior-loan check. Read the first mortgage note and security instrument before recording a junior lien. If the first loan is itself a DSCR loan, confirm its documents allow a second lien.

What the Network’s Investment Line Looks Like

The network’s investment-property line is a standalone line in first or second lien position. It is narrower than the primary-residence version.

On a primary residence, 90% CLTV exists only at a 720-or-better credit profile, and only up to $500,000. A line above $500,000 is primary-residence only. It requires a credit profile of 700 or better (720 on the longer-runway structure, the program with the 5-year draw and 25-year repayment). It caps at 75% CLTV and requires a full appraisal.

Line sizes run from $25,000 to $750,000, with a $10,000 floor in Michigan. After closing, the minimum subsequent draw is $1,000 on the longer-runway program, except Texas at $4,000. A borrower 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. Anyone owning more than 15 financed properties is not eligible.

Where the General Rule Breaks

LLC-held rentals. This is the common wall. A property already deeded to an LLC needs a vesting change before it can take this kind of line. Another route is a DSCR cash-out refinance, which can work for entity-held files, subject to program terms. Many bank lenders also prefer personal-name title.

Property type. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property are not eligible.

Vacant or newly converted rentals. With no lease or rental history to document, a rental line is harder to place, because lenders expect a tenant and a record.

A second line behind an existing one. A property that already carries a junior lien may not take another. That is also a cash-out problem later: a second lien generally has to be cleared or subordinated before a cash-out refinance of the first.

Recent listings. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.

Derogatory credit. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year foreclosure seasoning and a 4-year path for deed-in-lieu, pre-foreclosure, or short sale.

Texas. The waiting period and one-lien rule bind primary residences only. Texas investment properties are eligible as non-homestead transactions, limited to 10 acres.

The Variable-Rate Risk Is Real

The line’s pricing floats. The CFPB booklet says lenders sometimes offer a discounted introductory rate for a short period, and that variable-rate plans secured by a dwelling must have a cap on rate increases. Read the introductory terms as temporary.

Two payment shifts matter. The first is the float during the draw. The second is the move from interest-only to fully amortizing payments. Network lenders qualify the borrower on the interest-only payment calculated on the maximum draw, which is a useful stress frame. Run your own numbers on the repayment phase before drawing.

Keeping a cheap first mortgage means carrying two payments and two sets of terms. That is the price of protecting the first loan.

HELOC or DSCR Cash-Out: When Each Fits

The two products solve different problems. Pick based on title, the first loan’s value, and how the rental performs.

A DSCR cash-out refinance tops out around 75% LTV across most of the network, 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. DSCR compares rent to the full housing payment only. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management, and capex sit outside the calculation. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

The trade-off in plain terms: a DSCR cash-out gives up the locked-in first mortgage. A HELOC keeps it but needs personal-name title and a smaller line. If the first mortgage is cheap and the title is clean, the HELOC usually protects more. If the title is an LLC, a DSCR file may be the only practical route.

A Borrower Scenario

Say an investor holds a rental in her own name with a fixed first mortgage she wants to keep. Her credit profile is above 700, and she wants a modest line for repairs and reserves. Her combined balance stays under the 70% CLTV investment ceiling, and the line is under $500,000. She fits the investment line, borrower-level underwriting applies, and the first loan is never touched.

Now run a second investor with the same equity, but the rental is held in an LLC. Title blocks the line. The choices are re-deeding into his name, which carries its own legal and insurance consequences worth discussing with an attorney, or a DSCR cash-out that is reviewed on rental coverage. That one replaces the first mortgage.

How to Prepare and Shop

1. Pull your first mortgage documents. Confirm the balance and that nothing bars a junior lien.

2. Confirm title. Individual name or revocable trust is the baseline.

3. Check your credit. A report is valid for no more than 90 days at closing, with no rescores.

4. Gather rental evidence. A lease and rent history help the file.

5. Size the line against CLTV. Know the 70% investment ceiling before you ask for more.

6. Ask a broker to shop it. One application can be matched against several programs, instead of testing banks one by one.
