How Much Can You Borrow on a Bank Statement HELOC and Keep Your Current First Mortgage?

The Quick Read: It depends on the property’s occupancy and the equity left above your first mortgage: you keep the first by placing the new line in second position, and the limit is the equity left under the combined-leverage ceiling after your first balance, or the program’s maximum line, whichever is smaller. On an investment property, that ceiling is 70% combined loan-to-value (CLTV) and the maximum line is $500,000. The larger your first balance is relative to value, the less CLTV room remains for the line, and the dollar cap matters only when equity is ample.

• Investment property: 70% CLTV, a 700 minimum credit score, and lines from $25,000 to $500,000.
• Primary residence or second home: CLTV reaches 90%, but only with a 720-or-better credit profile.
• Title: the individual borrower or a revocable living trust holds the property. An LLC cannot.
• Draw: at least 75% of the line is drawn at closing, and the line is tested at its full commitment.
• Versus DSCR: a DSCR cash-out refinance replaces your first mortgage. This line sits behind it.

Lendmire is a mortgage broker. It places these lines with select wholesale lenders and is never the lender. Every figure below is subject to lender guidelines and full file review, and none of it is a commitment to lend.

How Is the Maximum Line Calculated?

The maximum line is the lower of two numbers. The first is the property’s value multiplied by the CLTV ceiling, minus what you owe on the first mortgage. The second is the program’s dollar cap. CLTV adds every lien on the property together and divides by value. Motley Fool’s glossary describes it the same way: the existing mortgage plus the proposed line, over the appraised value.

Work it in percentages, because the percentages tell you the answer faster than dollars do. Take an investment property with a 70% CLTV ceiling.

• Roomy equity: your first mortgage is 40% of value. That leaves 30 points of value for the line. On a higher-value rental, the $500,000 cap may bind first.
• Thin equity: your first mortgage is 65% of value. Only 5 points remain, so the line is small, and it may fall below the $25,000 floor and not be available at all.
• No room: your first mortgage is 70% of value or more. The ceiling is already used, and no line is available at that value.

The pattern is simple: the higher the first mortgage sits against value, the less room remains. The dollar cap binds only when equity is ample, so equity is usually the limit.

Two details change the arithmetic. First, the network counts the full line commitment toward CLTV, not just the portion you draw. Second, at least 75% of the line is drawn at closing, so you cannot open a large line and leave it idle. Size the line to the money you will actually use.

What Do the Limits Look Like by Occupancy?

Occupancy sets the ceiling, and the gap between tiers is wide. A quoted leverage figure means little until you know whether the property is a primary home, a second home, or a rental.

The table shows each occupancy’s top ceiling, and the 90% figure applies only at 720 or better. On a primary residence, lower scores step the ceiling down in tiers: a 640 score reaches 80% CLTV, and the 600 floor reaches only 60% CLTV on lines up to $400,000. Credit above 700 does not lift the investment ceiling. It only keeps the file eligible. Second-home lines step down in the same way. A primary line above $500,000 needs a 700-or-better profile (720 on the 5-year-draw structure described below) and caps at 75% CLTV.

Structure matters too. On investment lines, a 5-year interest-only draw period is followed by a 25-year fully amortizing repayment, and that is the only structure offered. Primary and second-home lines can also use a 3-year draw with a 17-year repayment. Pricing floats during both the draw and the repayment period and never converts to a fixed payment.

Debt-to-income (DTI) tops out at 50%, and the file is qualified on the interest-only payment calculated on the maximum draw. Lines at or below $500,000 ordinarily use an automated valuation rather than a full appraisal. Lines above $500,000 require a full appraisal.

One more limit: 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, WA). That footprint is narrower than the DSCR investor-loan footprint.

Why Does the First Mortgage Stay in Place?

The first mortgage stays because the new line is recorded behind it. Per the CFPB, when you already have a mortgage, a new home equity line is a second mortgage, and you pay it in addition to the first. Your existing rate, term, and balance do not change.

Lien position is the choice that decides this. The network’s line can sit in first or second position. A first-lien line on a property that already carries a mortgage pays the old loan off and replaces it, so it keeps nothing. If preserving the existing first is the goal, the line must be second.

That structure has appeal for an investor holding an older first mortgage they would rather not give up. A cash-out refinance would replace it. The line adds only the equity you need.

Keeping the first does not shield you from everything. Your first-mortgage payment still counts in your debt ratio. The new line’s payment floats, and the CFPB notes that HELOCs usually carry adjustable rates and varying payments. A bank statement line follows the same pattern.

How Do Bank Statements Change Qualification?

Bank statements change only how income is proven. They do not change the CLTV math, the credit floors, or the occupancy tiers. The file is reviewed on documented income under the applicable program, subject to lender guidelines. This is alternative documentation, not an absence of documentation.

Scotsman Guide describes the typical method. The lender reviews 12 to 24 months of personal or business statements and totals the eligible deposits. Transfers between your own accounts, loan proceeds, and one-time windfalls come out. On business accounts, the lender applies an expense factor, and Scotsman Guide uses 50% as an example. A profit-and-loss statement or an expense letter from a third-party tax professional can sometimes substitute. The lender sets the factor, not the borrower, and each program uses its own.

The result is a monthly qualifying income. The lender then runs credit, DTI, occupancy, title, and valuation. Deposits prove income, but they do not raise the dollar limit. Rental income on the subject property is not what sizes the line. That is the sharpest contrast with DSCR.

Reserves, seasoning, and similar conditions vary by lender, leverage, and transaction. Ask for the specific program’s requirements before you plan around any of them.

Key Terms Defined

HELOC: a revolving credit line secured by your property that you draw from repeatedly during a set draw period.

CLTV: combined loan-to-value, which is all liens on the property added together and divided by its value.

Second lien: a loan recorded behind your existing mortgage, so the first mortgage stays untouched.

Draw period: the stretch during which you can borrow and pay interest only, before full repayment begins.

DTI: debt-to-income, which compares your total monthly debts to your qualifying monthly income.

Subordination: an agreement that keeps a second lien behind a new first mortgage if you refinance the first later.

Where Does the Line Run Out?

The most common limits are title, thin equity, portfolio size, and the type of first mortgage you hold. Here is where files hit a wall.

LLC-held rentals. Fee simple or leasehold title must sit with the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title, per lender program requirements. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. For many investors, this is the deciding fact.

Portfolio size. A borrower is limited to three lines in total. Combined exposure across those lines is capped at $2,000,000 on the higher-leverage program and at $750,000 on the longer-runway program, separate from the per-line maximums. A borrower with more than 15 financed properties is not eligible. Large portfolios generally move to DSCR financing.

Government-backed first mortgages. Your FHA or VA first can stay in place. The line comes from a separate non-QM lender.

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

A later refinance of the first. If you refinance the first mortgage down the road, the second lender typically has to agree to stay behind it. That subordination is a lender decision, not a certainty. Plan for the possibility that it is not granted.

Value drops and sales. The CFPB’s HELOC booklet says lenders may reduce a credit line if the home’s value falls. A line generally has to be paid off when the property is sold.

Converting a home to a rental. If you plan to turn your primary residence into a rental, the occupancy tier changes. That moves the file from the primary tiers to the 70% investment ceiling.

Keep the First Mortgage or Replace It?

Keep it when the first mortgage carries terms worth protecting, you need a modest amount of equity, and the property is titled to you or a trust. Replace it when you need more leverage, the property sits in an LLC, or your portfolio has outgrown a handful of lines.

DSCR compares monthly rent to the full monthly payment on the property (principal, interest, taxes, insurance, and HOA dues). Across most programs in the wholesale network, a 1.00 ratio is where select programs start. A separate select-lender path goes below 1.00 with leverage and terms adjusted. Clearing the ratio is not the same as positive cash flow, since repairs, vacancy, management, and capex sit outside it.

For a DSCR cash-out refinance, the network tops out around 75% LTV on standard rentals, with about 6 months of seasoning as the common expectation. Credit minimums vary. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better opens the strongest leverage. If your goal is to pull equity out of several rentals held in entities, the complete DSCR loans guide is the better starting point than a personal-name line.

The honest tradeoff runs both ways. A DSCR cash-out reaches more equity but gives up the old first mortgage. The HELOC preserves the first but caps at 70% CLTV on a rental and requires personal title. Which one fits depends on the first mortgage’s terms, the size of the equity gap, and how the property is held. Lendmire’s bank statement HELOC program page lays out the line in more detail.
