How Much Can You Borrow on a Bank Statement HELOC on One Rental to Buy the Next?

The Quick Read: It depends on how much equity the rental has left after its first mortgage, because on an investment property the line tops out at 70% combined loan-to-value (CLTV) and $500,000, and you get whichever number is smaller. Bank statements prove your income, but they do not raise either limit.

• The formula: property value × 70% − your first mortgage balance = the room you have, then compare it to the $500,000 maximum line.
• Who it fits: self-employed owners with a 700+ credit score who hold the rental in their own name or a revocable trust, not an LLC.
• What it does not do: the line supplies cash. A separate loan, often a DSCR loan, buys the next property.
• The catch: you must draw at least 75% of the line at closing, so oversizing the line means oversizing your debt.

What Does a Bank Statement HELOC Actually Change?

It changes one thing: how your income is documented. A bank statement HELOC is a revolving second mortgage that is reviewed on documented income under the applicable program, subject to lender guidelines. The lender reads 12 to 24 months of personal or business deposits instead of tax returns.

That helps self-employed investors whose deductions make their returns look thin. It does not touch the equity rules, the credit floor, or the property rules.

On this network, a line on an investment property needs a 700 minimum score. Business-account deposit analysis asks for a 680 minimum, which sits below that 700 floor, so any file that qualifies on credit already clears the deposit-analysis requirement. The bank-statement piece therefore does not set the limit on a rental. Your credit score and your equity do.

It is also personal underwriting. The lender looks at your credit, your debts, and your debt-to-income ratio (DTI) using the deposit-derived income. DTI tops out at 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, so a bigger line limit stresses your ratio even if you plan to borrow less.

The rent from your rental does not size this line. That is the opposite of a DSCR loan, which looks at the property’s rent and ignores your personal income.

The Formula: What You Can Borrow on a Bank Statement HELOC on One Rental to Buy Another

Take the property value, multiply by 70%, subtract what you owe on the first mortgage, and the result is your room. Then compare that room to the $500,000 maximum line. The smaller number is your ceiling.

One detail trips people up. CLTV counts the full new line limit, not just what you draw. A line you open but don’t use still eats into your leverage.

Here are three scenarios, expressed as percentages of property value.

The first row is the one that surprises new investors. A purchase financed at 75% to 80% LTV already sits above a 70% cap on day one. A rental bought with a typical down payment will not support a line until you pay down the loan or the value climbs. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Appraisal works differently here than on most mortgages. A line of $500,000 or less ordinarily uses an automated valuation with no traditional appraisal, though a higher CLTV may require a secondary valuation. You can request a full appraisal in any case, which matters if you renovated and want the work reflected.

Which Rentals and Borrowers Fit?

The property must be a single-family home, a 2-4 unit building, a PUD, a townhome, or a condo (non-warrantable condos included). Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not offered. Lines on 2-4 unit properties carry a 640 minimum on one wholesale program, but the 700 investment floor already exceeds it.

Title is the sharpest dividing line. The individual borrower or a revocable living trust must hold title. LLCs, corporations, partnerships, and irrevocable or land trusts cannot. If your rental sits in an LLC, you need a vesting change first, or you can use a DSCR cash-out refinance, which can accommodate an LLC subject to lender program eligibility.

A few other limits apply:

• A borrower can hold up to three lines, with combined exposure caps that vary by program.
• Borrowers with more than 15 financed properties are not eligible.
• A property listed for sale, or listed within the past 60 days, is ineligible in several states.
• This equity-line product is available in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than Lendmire’s DSCR footprint.

How the Line Is Structured

The line can sit in first or second lien position. Investment lines run one structure: a 5-year interest-only draw period, then a 25-year fully amortizing repayment period. Pricing floats during both periods and never converts to fixed.

The CFPB’s explanation of home equity lines describes the same open-end design: you borrow, repay, and borrow again against the equity. This product requires you to draw at least 75% of the line at closing. After that, each additional draw has a $1,000 minimum, with a higher minimum in Texas.

The 75% rule shapes how you size the line. You cannot open a large line and leave it idle as a safety net. Most of it becomes debt on day one, and you pay interest on it.

Two Approvals, Two Lenders: How the Sequence Works

Plan on two separate approvals. The line comes first, and the purchase loan comes second. Each lender reviews something different.

1. The equity line lender looks at you: credit, deposits, DTI, and the collateral rental.

2. The purchase lender looks at the new property, and on a DSCR loan, at its rent against its own payment.

DSCR (debt service coverage ratio) is monthly rent divided by the property’s full monthly payment: principal, interest, taxes, insurance, and any HOA dues. Many select DSCR programs start at 1.00. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage.

Clearing 1.00 does not mean the property produces positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the ratio. The payment on your equity line also generally sits outside the new property’s DSCR, but it still comes out of your pocket every month.

Complete DSCR purchase terms are in the complete DSCR loans guide. In short, most purchase files land at 75% to 80% LTV, and select programs reach 85% LTV with roughly a 700+ score. Credit floors vary by program, so confirm the minimum for the specific loan you are pursuing. Reserves commonly run about 6 months of the full monthly payment, though they vary by lender, leverage, and loan size.

Can the Draw Be Your Down Payment?

Sometimes. Whether a purchase lender accepts equity-line proceeds as the down payment, or counts them toward reserves, varies by program. Ask before you open the line, not after.

The math deserves a hard look. Buy at 75% to 80% LTV with a fully borrowed down payment, and you are financing close to 100% of the purchase price across two loans. The new property then has to carry its own mortgage while you also service the line. If it falls short, your first rental pays for the difference, because it is the collateral. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

The CFPB’s HELOC booklet stresses the same point: the property secures the line, a lender can reduce the line if value falls, and you can lose the home if you cannot repay.

One more trap involves the exit plan. Some investors plan to refinance the new DSCR purchase soon after closing to repay the line. Cash-out refinances on a standard rental top out around 70% LTV, with about 6 months of seasoning as the common expectation. Many DSCR loans also carry prepayment penalties, so refinancing early can cost real money. Check the penalty structure before you count on that exit. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

Which Tool Fits Which Situation?

Three tools compete for the same job of turning equity into purchase cash. Each fits a different file.

The line on your primary residence reaches up to 90% CLTV, and only with a 720 or better credit profile, while the rental line stops at 70% CLTV. It also puts the roof over your head at stake, which is a different risk from putting a rental at stake.

The cash-out route replaces your first mortgage rather than adding a second lien. That helps when the existing first mortgage is no longer attractive, and it is reviewed on the property’s rent rather than your deposits.

What to Gather for the Bank Statement Path

Programs typically ask for 12 to 24 months of personal or business statements. The underwriter strips out transfers between your own accounts, refunds, and loan proceeds, then averages what remains. Business accounts may carry an expense factor, or a CPA-prepared profit-and-loss statement may apply. Both vary by program.

Prepare this list before you apply:

• Consecutive statements for every account used for income.
• A credit profile at 700 or better, with a report no more than 90 days old at closing.
• Your current first mortgage statement on the rental.
• Proof of vesting in your name or a revocable trust.
• A clear plan for what the draw buys and what loan finances the rest.

Credit history details matter too. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year seasoning path after a foreclosure and 4 years after a deed-in-lieu, pre-foreclosure, or short sale.

What Is the Real Risk Once You Draw?

You carry two payments, and the first one changes. During the 5-year draw period, you pay interest only. Then the 25-year repayment period begins, and the payment steps up because principal joins it. Because pricing floats, the payment can also move.

Stress-test three things before you commit:

1. Can the new property cover its own loan if it sits vacant for a stretch?

2. Can your income carry both payments at once?

3. Can you handle the step-up when the draw period ends?

If any answer is shaky, size the line smaller or buy with more cash. Lenders also review these limits for you. DTI is figured against the maximum draw, so an oversized line can sink an otherwise clean file.
