Bank Statement HELOC Lenders for Keeping a Locked-in First Mortgage

The Quick Read: A bank statement HELOC is a standalone second-lien line that sits behind your existing mortgage, so the first loan’s rate, term and payment stay as they are, while 12 or 24 months of bank deposits stand in for tax-return income. The lender still reviews your credit, your equity and the property. It also counts the first mortgage in your combined leverage.

• On an investment-property line, the ceiling is 70% CLTV, with a 700 minimum credit profile and a maximum line of $500,000.
• On primary residences and second homes, 90% CLTV exists only at a 720-or-better credit profile, on lines up to $500,000.
• Title must sit in your personal name or a revocable living trust. An LLC generally cannot hold these lines.
• The first mortgage payment also feeds into your debt ratio, so the loan you keep still shapes how you qualify.
• A bigger equity pull, entity title or a larger portfolio usually points toward a DSCR cash-out refinance instead.

Every figure here is a typical range from select lenders in Lendmire’s wholesale network and is subject to lender guidelines. This is not a commitment to lend.

Key Terms Defined

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

Second lien: A loan recorded behind your existing mortgage. If the property is ever sold or foreclosed on, the first lien gets paid before it.

Draw period and repayment period: The draw period is when you can borrow from the line, often paying interest only. The repayment period follows, when the balance amortizes.

Subordination: A lender’s written agreement to stay in second position, which matters if you refinance the first mortgage later.

Bank statement income: Income calculated from months of deposits instead of tax returns. It is reviewed on documented income under the applicable program, subject to lender guidelines.

DSCR (debt service coverage ratio): A rental property’s income divided by its full monthly housing payment. DSCR loans qualify mainly on that property-level ratio rather than on your personal income.

What Is a Bank Statement HELOC, and Why Does the First Mortgage Stay Put?

The first mortgage stays put because this product is a separate loan with its own lien. You borrow against equity, meaning the property’s value minus what you owe. The new line is recorded behind the old mortgage rather than replacing it.

HousingWire’s non-QM guide describes the bank statement HELOC as a revolving second lien for self-employed homeowners who qualify on bank statements. It also describes a closed-end second mortgage as the fixed lump-sum alternative. The same guide puts bank statement loans at 34% of non-QM volume and DSCR loans at 29%. Those shares cover the whole non-QM market, not HELOCs alone.

Why does a locked-in first mortgage matter? Say you bought or refinanced when your payment was modest. A first-lien cash-out refinance would swap that loan for a new one, and the whole balance would be repriced at current terms. A second-lien line prices only the new money.

Lien position is a deliberate choice. The product can technically be written in first or second position, but a first-lien line would pay off your existing mortgage, which defeats the goal. For keeping a locked-in rate, you want a standalone line placed in second position behind your current mortgage.

“Bank statement” refers only to how income is documented. It is not a shortcut around underwriting. Credit, equity, property type and title all get reviewed.

Which Lenders Offer This, and How Do You Find the Right Fit?

Large retail lenders are a low-likelihood source for this product. Wholesale non-QM channels are the higher-likelihood route. Lendmire is a mortgage broker, not a lender. It arranges financing by shopping select lenders in its wholesale network and matching the scenario to the program.

Which lender fits depends on the file: the occupancy, the credit profile, the equity left after the first lien, the title and the state. A strict overlay at one lender may be a non-issue at another. That is the reason to compare programs instead of calling one source.

Availability is narrower than the DSCR footprint. DSCR investor programs run across 41 markets, including Washington, D.C. The HELOC lines are available in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA.

How Does Underwriting Treat the Line, Step by Step?

Underwriting follows a fixed sequence, and the first mortgage appears in four of the steps: lien position, the equity test, the debt ratio, and the documents.

1. Occupancy and lien position. The file is set up as a standalone line behind the existing first.

2. Documents. Plan on 12 or 24 months of complete bank statements, every page, personal or business. A current statement for the first mortgage is also needed.

3. Credit. Minimums depend on occupancy: 600 on a primary residence, 640 on a second home and 700 on an investment property.

4. Equity test. The lender adds your first-mortgage balance to the full line limit, not the amount you plan to use, and divides by value.

5. Property and title review. Eligible property types and title forms are checked, as covered below.

6. Debt ratio. The maximum DTI is 50%. The lender qualifies you on the interest-only payment calculated on the maximum draw, and the first mortgage payment sits in the ratio too.

7. Valuation. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal, though a higher CLTV may require a secondary valuation. A full appraisal is required on every line above $500,000, and you can request one in any case.

Deposits become qualifying income through each lender’s own method. Expense factors, transfers between accounts and commingled personal and business activity are treated differently from lender to lender. Clean, consistent deposits make the file easier to read.

The structure also deserves a close look before you sign. The CFPB’s HELOC explainer describes a draw period followed by a repayment period, often 10 or 20 years, and notes that HELOC rates are usually variable. On the investment structure here, the draw is 5 years and the repayment is 25 years, with the rate floating throughout.

You also cannot treat the line as a dormant cushion, because at least 75% of the line is drawn at closing. Size the limit to money you will put to work.

How Much Room Does the First Mortgage Leave?

The room is whatever sits between your first-mortgage balance and the CLTV ceiling. The table uses the 70% ceiling on an investment-property line. These are illustrative percentages, not market data.

A small first balance can hit the $500,000 line cap before the CLTV limit. A large first balance runs out of CLTV room first. Either way, the first mortgage is working against the ceiling the whole time.

What Structures and Variations Exist?

The ceilings depend on occupancy, so one number never describes the whole product.

• Investment property: 70% CLTV at 700 or better credit, lines from $25,000 to $500,000, 5-year draw and 25-year repayment only.
• Second home: 90% CLTV only at a 720-or-better profile, with lines up to $500,000. The minimum credit is 640.
• Primary residence: The same 90% ceiling applies only at 720 or better, with that tier running up to $500,000. Lines above $500,000 are available on primary residences only, need a full appraisal, and require 700 or better credit (720 on the 5-year-draw, 25-year-repayment structure).

On primary residences and second homes, lenders also offer a shorter structure: a 3-year interest-only draw with a 17-year repayment. Investment lines do not use it.

Eligible properties include single-family, 2-4 units, PUDs, townhomes and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered.

Where Does the General Rule Break?

Most of the friction comes from edge cases that surprise people.

LLC-owned rentals. Title must be held by an individual or a revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold it. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead.

Thin equity. If your first mortgage already sits near 65% of value, the available line may be too small to justify a second payment.

Deferred or modified first mortgages. A deferred balance counts in CLTV even though no payment is due on it. That shrinks the available line.

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

Portfolio size. You are limited to three lines, and a borrower who owns more than 15 financed properties is not eligible.

Rental use and sale. Read how the line treats renting and selling. The CFPB’s HELOC booklet warns that renting out your home may be prohibited under a line’s terms, and that a sale generally means repaying the line in full right away. Confirm the terms before you plan around either one.

Heavy rehab. A line suits modest, staged work. A gut renovation usually calls for a different tool.

How Should You Compare Lender Offers?

Compare on structure first. A broker can run these checks across several lenders at once.

• Lien position: Is it a standalone second lien, with the first left alone?
• Draw rules: What is the draw period, and how much must be drawn at closing?
• Title and vesting: Does your personal-name or revocable-trust title fit?
• Payment test: Is the line qualified on the interest-only payment at the maximum draw?
• States served: Does the program reach your property’s state?
• Valuation: Is it automated or a full appraisal, and what does your CLTV trigger?

Ask what happens if you refinance the first mortgage later. In general, a new first lien has to sit ahead of your line. That usually means the second-lien lender must agree to subordinate, or you pay the line off. Whether a lender will subordinate varies by lender, so ask before you sign.

Keep the First Mortgage or Replace It?

Keep it when the equity pull is modest relative to value, the first mortgage is worth protecting and your debt ratio has headroom. Replace it when you want a larger pull, entity title or a fixed structure.

The more of your total debt that is the first mortgage, the more a refinance would reprice. A small first balance makes the lock less valuable. A large one makes it more. That is a rule of thumb, not a formula.

On a DSCR cash-out refinance, the 75% ceiling applies to standard rentals. Short-term-rental collateral caps at 70%.

DSCR (debt service coverage ratio) loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. For the DSCR column of the table, most standard programs want about 6 months of seasoning, and most want around a 660 credit score. A 620 floor exists in parts of the network, and 700 or better unlocks the strongest leverage tiers. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. A ratio above 1.00 is not the same as positive cash flow, because repairs, vacancy and management sit outside the calculation.
