How Much Can You Borrow on a Bank Statement HELOC for Buying Another Rental House?

The Quick Read: It depends on equity, not deposits: on an investment property the network’s ceiling is 70% combined loan-to-value (CLTV) with a $500,000 maximum line, so your limit is the property’s value times 70% minus every lien already on it, and bank statements only prove the income behind the request. The collateral you choose matters more than anything else, because a primary home can reach a higher ceiling than a rental can.

• The formula: value times the CLTV ceiling, minus existing liens, capped at the program’s maximum line.
• Investment property: 70% CLTV, a 700 minimum credit score, and a line up to $500,000, subject to lender guidelines.
• Primary home or second home: up to 90% CLTV, but only at a 720-or-better credit profile.
• Bank statements: they document income for the debt-to-income test and do not raise the ceiling.
• The purchase is a separate approval: the lender financing the new rental sets its own down payment, reserve and source-of-funds rules.

How Is the Borrowing Limit Calculated?

The limit is the smaller of two numbers. The first is value times the CLTV ceiling, minus what is already owed. The second is the program’s maximum line amount. Whichever is lower wins.

CLTV stands for combined loan-to-value. It adds the first mortgage balance and the full new line limit, then divides by the property’s value. The lender tests the full limit, not just the amount you plan to draw. A line opened “just in case” still uses up room on the combined test.

Bank statements do not appear anywhere in that formula. They show the lender that you earn enough to carry the payment, which is a separate question from how much equity the property can support. Self-employed borrowers often assume strong deposits will lift the ceiling. Across the wholesale network Lendmire works with, they do not.

Lendmire is a mortgage broker, not a lender. It places files with select wholesale partners, and every figure here is subject to lender guidelines and a full file review.

What Do the Numbers Look Like at Different Balances?

The easiest way to see the formula is to run it as percentages of value. Dollar figures change by property, but the percentages stay the same. These three examples use an investment property at the 70% ceiling.

A rental with a low first mortgage. Say the first mortgage is 40% of the property’s value. The new line can take the combined total to 70%, so the room is 30% of value. The $500,000 cap only matters if that 30% would exceed it, which happens on high-value property.

A rental with a mid-sized first mortgage. Say the first mortgage is 55% of value. The room is 15% of value, so the usable line is smaller than many owners expect. A rental bought with a conventional down payment and held for a few years can easily sit in this range.

A rental with no room. Say the first mortgage is 70% of value or more. The room is zero. A statement-qualified line cannot help this property, however strong the deposits look. A cash-out refinance sized on rental income is a different test, covered below.

Now run the same low-balance example against a primary home, again with a first mortgage at 40% of value. At a 720-or-better credit profile, the ceiling reaches 90% CLTV, so the room is 50% of value on the home, compared with 30% of value on a rental carrying the same balance. That gap explains why so many investors secure the line with their home.

Should the Line Sit on Your Home or on an Existing Rental?

Both are possible on this network, but the ceilings differ sharply. The home usually gives more room. The rental keeps your residence out of the picture.

Two details on the rental side are worth knowing. A score of 720 and a score of 700 both reach the same 70% on an investment property, so a higher score buys eligibility rather than extra leverage. And a line above $500,000 is available on a primary residence only, requires a credit profile of 700 or better (720 on the program with the five-year interest-only draw), caps at 75% CLTV and needs a full appraisal.

Availability is also narrower than most investors expect. This HELOC product is offered in Lendmire’s 16 full-service states, which is a smaller footprint than the 41-market DSCR platform. A lender outside that footprint may not write investment lines at all. BiggerPockets notes that many banks and credit unions only offer home equity lines on a primary residence, so even finding a rental-secured line takes some searching.

Title matters too. The borrower must hold title personally or through a revocable living trust. An LLC cannot hold title on this product, so a rental already deeded to an LLC needs either a vesting change or a different structure, such as a DSCR cash-out refinance.

What Do Bank Statements Decide, and What Don’t They?

Bank statements decide income. They do not decide the ceiling, the credit tier or the line cap. That distinction clears up most of the confusion around this product.

Non-QM lenders typically analyze 12 or 24 months of statements in place of W-2s, as Scotsman Guide reports. The income qualifies under the applicable program, subject to lender guidelines. In practice, underwriters remove transfers between your own accounts, refunds and loan proceeds. For business accounts, they usually apply an expense factor to the deposits that remain, and that factor varies by program.

The resulting income feeds the debt-to-income test. The maximum is 50%, with 45% for credit profiles from 600 to 679, and anything above 45% needs a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on the balance you actually carry. A large line can therefore strain your ratio even if you draw very little.

Business accounts require a 680 minimum for the deposit analysis. The 600-to-679 debt-to-income tier therefore applies to other income documentation, not to business-account deposits. An investment line already floors at 700, so bank-statement income is never the binding constraint on a rental-secured line. Equity and credit decide those files.

Can the Line Fund the Down Payment on the Next Rental?

Often it can, but the lender financing the new rental decides. That lender applies its own rules on down payment, reserves and the source of funds, so this is a second approval and not a formality.

Rental purchase loans commonly require 20% to 25% down, which means 75% to 80% LTV. Select programs reach 85% LTV, or 15% down, with a score near 700 or better. Whether borrowed funds also count toward reserves is a question for the purchase lender, since reserve rules vary by lender, leverage, loan size and transaction type. Reserves commonly run around six months of PITIA, and larger loans step up from there.

Because the line carries a floating payment, the purchase lender will count it. Investors on BiggerPockets make the same point: cash flow has to cover the HELOC payment as well as the new loan. Plan on two separate tests.

1. The HELOC test. Your documented income, credit and debt-to-income ratio decide how large a line you can open.

2. The DSCR test. The new rental’s monthly rent is divided by its PITIA (principal, interest, taxes, insurance and any HOA dues). Select programs start at 1.00, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

Clearing 1.00 does not mean the property produces positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses all sit outside it, and the HELOC payment sits outside it too. Read more in Lendmire’s complete DSCR loans guide.

One more point on sequencing. The line must be open, and the funds seasoned and documented, before the purchase lender reviews the file. Opening it first also avoids a surprise if the line’s valuation comes in lower than expected.

How Does the Line Behave After You Open It?

Its structure is less flexible than the word “line” suggests. On an investment property, the network’s line runs a five-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. The pricing floats through both the draw and repayment periods and never converts to fixed.

That 75% initial draw changes the sizing question. If you open a large line to keep options open, most of it begins accruing interest on day one. Size the limit to the purchase you actually plan, not to the largest number the formula allows. After closing, the minimum subsequent draw is generally around $1,000, though one program states it and the other does not.

Valuation is usually light on a rental-secured line. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal, though a higher CLTV may trigger a secondary valuation, and a borrower may request a full appraisal. Since an investment line caps at $500,000, it sits in the automated-valuation lane.

The CFPB describes a HELOC as an open-end line you can borrow against repeatedly during a draw period, and adds that a lender may stop further draws if the home’s value drops significantly. The line you planned around may not be fully available later. The same CFPB page warns that you could lose your home if you fall behind on a line secured by it, which is the central risk when your residence is the collateral.

The CFPB’s consumer booklet says lenders generally let you borrow up to a percentage of your equity, and requires them to disclose the terms and costs. Read those disclosures before signing.

HELOC or DSCR Cash-Out Refinance?

A DSCR cash-out refinance sizes on the rental’s income and LTV. A bank statement HELOC sizes on CLTV and your personal income. Which fits depends on the property, the title and the investor.

Rental income drives the DSCR cash-out refinance, and the common expectation is about six months of seasoning. The ceiling is about 75% LTV on a standard rental and 70% on a short-term rental, subject to lender guidelines. Short-term rental files typically want a 640 or better score and about 12 months of hosting history. Credit floors run around 660 on most programs, with a 620 floor in parts of the network and 700-plus opening the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders).

The refinance replaces your first mortgage, so the payment is one fixed obligation instead of a first mortgage plus a floating line. The tradeoff is that you give up your existing first-mortgage terms.

For portfolio investors, the DSCR route often scales further. An investor holding several financed properties through LLCs is outside the HELOC’s reach, since title must be personal or a revocable trust. A borrower with more than 15 financed properties is not eligible for the HELOC at all, and exposure is limited to three lines in total.

Who Should Skip This Route?

Some situations make the HELOC a poor fit, and recognizing them early saves effort.

• LLC-titled rentals. The product does not accept LLC, corporation, partnership or irrevocable trust title.
• Rentals with little equity. If the first mortgage already sits near 70% of value, there is no room to size.
• Investors who cannot absorb a floating payment. Pricing floats and never converts to a fixed structure.
• Borrowers under 700 who want to use a rental as collateral. That is the hard floor on investment lines.
• Properties the program does not accept. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agriculturally zoned property are not eligible.

If the number does not pencil on a rental-secured line, that is useful information. It may point toward securing the line with a primary home, buying a smaller property, or refinancing a rental on its income. A larger down payment on the new purchase lowers the monthly payment and can lift the DSCR, but it does not erase leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
