The Quick Read: To keep a low first mortgage, you ask for a line in second-lien position, so the new loan sits behind the existing one and only the new money is priced at today’s terms. The bank statements change how income is documented. They do not change where the lien sits, and credit, combined leverage, title, and valuation are still tested.
- Pick second-lien position on purpose. A first-lien line pays off and replaces the existing mortgage.
- The existing first balance counts in full toward combined loan-to-value (CLTV), which shrinks the line you can get.
- On an investment property, the network ceiling is 70% CLTV, with a 700 minimum credit score and a $500,000 maximum line.
- Title must sit with an individual or a revocable living trust. An LLC cannot hold title on these lines.
- At least 75% of the line is drawn at closing, so the cost starts on most of it right away.
An investor sitting on a legacy first mortgage with strong terms has a real reason to protect it. The second-lien line lets that loan run untouched while equity gets tapped behind it. The trade-off is a second payment, a floating balance, and a lien that complicates any later refinance of the first. This article walks the mechanics in order, then covers where the general rule breaks.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Availability is limited. Lendmire brokers these lines through select wholesale partners in 16 full-service states (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA), which is narrower than the 41-market DSCR footprint. Lendmire is a broker and never the lender, and every figure below is subject to lender guidelines and full file review.
What Is a Bank Statement HELOC?
A bank statement HELOC is a home equity line of credit where income is documented from deposits in personal or business bank accounts instead of traditional personal-income documentation. It is still a HELOC. The underwriting questions are about credit, debt-to-income, combined leverage, title, and valuation. Only the income proof changes.
Per the CFPB’s HELOC explainer, a line of credit has a draw period followed by a repayment period, and the rate is usually variable, so payments can move month to month. That structure carries over to the non-QM version. On the investment-property lines in Lendmire’s network, pricing floats through both the draw and repayment periods and never converts to fixed.
One point about the product name matters for investors. Many people think “bank statement” means lighter scrutiny. It does not. A file with thin credit, too much combined debt, or the wrong title will stall whether income comes from traditional personal-income documentation or deposits.
Key Terms Defined
CLTV (combined loan-to-value): The first mortgage balance plus the line amount, divided by the property value.
Lien position: The order in which loans on a property get paid if it is sold or foreclosed. First lien is paid first.
Draw period: The stretch when you can borrow from the line, usually interest-only on these structures.
Subordination agreement: A written agreement where a lender holding a junior lien agrees to stay behind a new loan.
DTI (debt-to-income): Monthly debt obligations divided by qualifying monthly income.
Expense factor: A percentage taken off business-account deposits to estimate what is left after operating costs.
How Do You Keep the First Mortgage?
You keep it by choosing second-lien position. The network’s standalone line can be written in first or second position, and those are two different products. A first-lien line on a property that already carries a mortgage pays that off and replaces it. That is a refinance in all but name, and it defeats the purpose.
So the first step on every file is stating the position you want. Ask for second lien. Then confirm the existing first stays in place and in good standing.
Keeping the first does not mean the first is unaffected. Three things still touch it:
1. Its balance counts in full when CLTV is calculated, so a larger balance means a smaller line.
2. Its payment counts in DTI alongside the new line.
3. It limits future moves, because a later refinance of the first needs the line lender’s cooperation (covered below).
Think of the first mortgage as protected in its terms, not protected from the file review.
What Does the Lender Still Test?
Everything except the income proof is the same as any equity line. The table separates what the bank statements change from what they leave alone.
| Item | Changed by bank statements? | What applies |
|---|---|---|
| Income proof | Yes | Deposits averaged over a lookback window |
| Credit score | No | 700 minimum on investment lines |
| Combined leverage | No | 70% CLTV ceiling on investment |
| DTI | No | 50% max; 45% for 600-679 credit |
| Title | No | Individual or revocable trust only |
| Valuation | No | Automated at or below $500,000, unless more is required |
Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal, though a higher CLTV may require a secondary valuation, and a borrower can request a full appraisal in any case. Qualification also runs on the interest-only payment calculated on the maximum draw, not the amount you plan to use. Size your plan around the full line.
How Do Deposits Become Qualifying Income?
Underwriters average eligible deposits over a lookback window and treat the result as monthly income. The method below is the general bank-statement approach, as laid out in Docsumo’s explainer on bank statement income verification. Specific lender treatment varies.
1. Gather 12 or 24 months of complete, consecutive statements, personal or business.
2. Pull out every deposit.
3. Strip non-income items: loan proceeds and transfers between your own accounts. Large or unusual deposits need a source or they come out.
4. On business accounts, apply an expense factor, then multiply by your ownership share. Docsumo describes a 50% default factor, with a lower one possible when a CPA or tax preparer documents it.
5. Average what is left across the window.
A 24-month window smooths out seasonal swings. A 12-month window is easier to assemble. On personal statements, eligible deposits generally count in full, and business statements usually come in as supporting documents.
The resulting monthly figure then runs through DTI like any other income number. On these lines the maximum is 50%, dropping to 45% for credit profiles between 600 and 679, and any ratio above 45% requires a 680 minimum. Investment lines start at a 700 score, so that lower band matters mainly for owner-occupied lines.
Deposit hygiene before applying
- Keep business and personal money in separate accounts. Commingled accounts complicate the calculation.
- Label or document large one-time deposits before the underwriter asks.
- Avoid moving money between your own accounts right before the lookback window ends. Those transfers get stripped anyway and add noise.
- Know your ownership share. Under 100% means the business deposits get scaled down.
How Big a Line Does Your Equity Support?
The line is the room left under the CLTV ceiling after the first mortgage, capped by the maximum line size. On an investment property that means 70% CLTV and a $500,000 ceiling. There is no tier above that for investment lines.
Run the logic in words. Take a rental worth a given amount. Multiply its value by 70%. Subtract the existing first mortgage balance. What remains is the most the line could be, before the $500,000 cap. A property with a small first balance runs into the cap first. A property with a large first balance runs out of CLTV room first. Lendmire’s illustrative calculator can convert the percentages to dollars for a specific file.
Occupancy changes the answer sharply, so state it before quoting any ceiling:
| Occupancy | Credit tier | Ceiling | Max line |
|---|---|---|---|
| Investment property | 700+ | 70% CLTV | $500,000 |
| Second home | 720+ | 90% CLTV | $500,000 |
| Primary residence | 720+ | 90% CLTV | $500,000 |
The 90% figure exists only with a 720 credit profile, and a primary-residence line above $500,000 needs a full appraisal and a score of 700 or better (720 on the longer-runway structure), capped at 75% CLTV. A larger first mortgage on a rental simply leaves less room under 70%.
Keep the First or Refinance? A Decision Test
Keeping the first makes sense when the existing loan has terms you would not get today and the cash need is modest. A cash-out refinance reprices the whole balance at current terms, while the line prices only the new money. That logic is common in consumer-finance commentary, and it is the core reason investors ask this question.
The honest test has four parts:
- Size of the cash need. The line tops out at $500,000 on an investment property. Bigger needs push toward a refinance.
- Title. If the rental is deeded to an LLC, a line is not available as it stands. A DSCR cash-out refinance may be the fit instead, subject to lender program eligibility.
- Value of the first. If the first mortgage is not meaningfully better than current terms, replacing it costs you little.
- Preference for one payment. A line adds a second payment and a floating one.
| Factor | Second-lien line | Cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| What gets repriced | New money only | Entire balance |
| Payment structure | Second payment, floating | One payment |
| Title | Individual or revocable trust | LLC possible on DSCR programs |
| Draw at closing | At least 75% of the line | Lump sum |

Where the General Rule Breaks
The clean story, “keep the first, borrow behind it,” has edges. These are the ones that derail files.
A later refinance of the first. This is a common trap. Per Nolo’s explanation of subordination agreements, mortgage liens follow a first-in-time, first-in-right rule. If the first is paid off in a refinance, the line would normally move up to first position. The new first-lien lender generally wants first position, so the line holder has to agree to stay behind it. That lender may agree, decline, or take weeks. If it declines, the exits are paying off and closing the line first, or doing a cash-out refinance that rolls everything into one new first. Plan the exit before taking the line.
Title and LLCs. On these lines, title must be held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
Document mismatch. Commingled accounts, large unsourced deposits, and ownership under 100% all reduce or complicate the deposit calculation. A file that looks fine on paper can lose a meaningful chunk of qualifying income once the underwriter strips it down.
Property type. Eligible collateral includes single-family, 2-4 units, PUD, townhome, and condominium (including non-warrantable). Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.
Exposure limits. A borrower is limited to three lines, with combined exposure capped 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 listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
Credit history. Bankruptcy requires a 4-year seasoning period from discharge or dismissal. Foreclosure-family history splits by program on primary residences and second homes, and investment files follow a 7-year path for foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
What Are the Real Costs of Keeping the First?
The costs are structural, not just pricing. You take on a second payment. Pricing floats and does not convert to fixed on these investment lines. And the draw rule matters: at least 75% of the line is drawn at closing, so a traditional pay-only-what-you-use line is not how this works.
The investment structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. When the draw ends, the payment steps up because principal begins amortizing. The CFPB’s HELOC brochure makes the same point for lines generally: some allow interest-only payments during the draw, and a variable payment can change even if you draw nothing more.
Total debt on the property also rises by the line balance, and both loans are secured by the same collateral. Lenders can also freeze or reduce a line under their terms. That is why investors using these lines for down payments or renovations should plan repayment, not just access.
Documents and Steps to Apply
A clean file starts with the right paper. Gather these before submitting:
- 12 or 24 months of complete bank statements, all pages, personal or business
- Documentation of any large deposit outside the normal pattern
- Current mortgage statement for the first
- Proof of title and vesting (individual or revocable trust)
- Credit authorization (the report cannot be more than 90 days old at closing, and no rescores are available)
Then the sequence:
1. Confirm the property is eligible and titled correctly.
2. Estimate CLTV using the existing first balance and a realistic value.
3. Confirm credit meets the 700 minimum for an investment property.
4. Clean up deposits and separate accounts where possible.
5. Submit the file for lender review through a broker with access to select wholesale partners.
6. Review the valuation result.
Why files stall is usually predictable: title in an LLC, a first balance that eats the CLTV room, unsourced deposits, credit just under the floor, or an ineligible property type. Check those five first.
Where Does a DSCR Loan Fit?
When the property is in an LLC, or the cash need exceeds the line cap, a DSCR cash-out refinance is the more common route. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and the network’s cash-out tops out around 75% LTV with roughly 6 months of seasoning as the common expectation. Clearing 1.00 coverage is where select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. The tradeoff is that it replaces the first mortgage, which is the thing this article is about keeping. Lendmire’s complete DSCR loans guide covers how those files work.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Will my first mortgage terms change if I add a second-lien line?
No. The first loan keeps its existing terms. What changes is the total debt on the property, the CLTV, and your DTI, because the first balance and payment still count in the file. A later refinance of the first is where the line creates friction.
Can a rental held in an LLC get this kind of line?
Not as titled. These lines require title in the individual borrower’s name or a revocable living trust. A property deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead, subject to lender program eligibility.
What is the maximum on an investment property?
The network ceiling is 70% CLTV with a $500,000 maximum line and a 700 minimum credit score. There is no higher investment tier. Higher ceilings apply only to primary residences and second homes, and the 90% figure requires a 720 credit profile.
Do bank statements make underwriting lighter?
No. They only change the income proof. Credit, DTI, combined leverage, title, and valuation are all still reviewed. Eligible deposits get averaged, non-income items are removed, and business deposits are reduced by an expense factor.
What happens if I want to refinance my first mortgage later?
The line holder generally has to agree to stay in second position, which is a subordination agreement. It can take weeks, and the lender can decline. If it does, the options are paying off the line or rolling everything into a new cash-out first.
