How Much Can You Borrow on a Bank Statement HELOC at a Credit Union for Local Landlords?

The Quick Read: Usually up to 70% combined loan-to-value on an investment property, minus what you still owe on the first mortgage, with a line size from $25,000 to $500,000 through select lenders in Lendmire’s wholesale network, subject to lender guidelines; a credit union is rarely the source of a bank statement line on a rental.

• The formula: available line equals property value times the maximum combined loan-to-value (CLTV), minus existing liens.
• The leverage ceiling: on this network, an investment-property line tops out at 70% CLTV, and a 700 or 720 score reach the same ceiling.
• The credit floor: 700 is the minimum on an investment line, with no tier beneath it.
• The title test: the rental must sit in your own name or a revocable living trust, not an LLC.
• The income test: bank statements change how income is proven. They do not change how much equity you have.

Why a Credit Union Is Rarely the Source

A bank statement HELOC is a non-QM product. It comes mostly from wholesale lenders reached through a broker, not from the local credit union branch. Credit unions mostly run traditional home equity lines, and many either skip rentals or ration them.

A BiggerPockets discussion on HELOCs for investment property notes that not every credit union lends on rentals, so a borrower has to ask directly.

So the useful question is not how much a credit union will lend. It is which lender will write a bank statement line on a rental, and how large that line can get. Lendmire arranges these lines as a broker. It does not lend, and every figure below is subject to lender guidelines and full file review.

What a Bank Statement HELOC Actually Is

A bank statement HELOC is a revolving line of credit where income is documented through deposits instead of tax returns. The standard non-QM approach, as Scotsman Guide describes it, uses 12 to 24 months of personal or business bank statements. The lender then applies an expense factor to business deposits, or accepts a profit-and-loss statement prepared by a third-party tax professional. The 50% factor in that article is an illustration. Each program sets its own.

Here is the part landlords often miss. It is not a no-documentation loan. Credit, debt-to-income, equity, and the property are all still reviewed. The borrower is reviewed on documented income under the applicable program, subject to lender guidelines.

This path fits a landlord with heavy write-offs, several entities, or tax returns that show little income. It fits less well for a W-2 employee with one rental, since a standard line may work without the extra documentation.

How Much Can You Borrow? The Three-Limit Rule

Three limits cap every rental line, and the smallest one wins. The first is equity: value times the maximum CLTV, minus liens. The second is the dollar cap on the product. The third is your credit and debt load.

On Lendmire’s network, an investment-property line runs from $25,000 to $500,000 with a 70% CLTV ceiling. Scores of 700 and 720 both reach 70%, so credit above 700 buys eligibility, not more leverage. Primary-residence and second-home lines reach higher ceilings, but that does not apply to a rental.

Within this network, the investment figure is 70%, and it should not be read as a market average.

Run the equity math on three rental scenarios, expressed as percentages of value.

CLTV is the first mortgage plus the new line, divided by value. The last row is the one that surprises people. A rental financed near 65% leaves so little room that a line is rarely worth setting up.

Which Limit Binds First?

For most landlords, equity binds first. For owners of high-value, low-debt rentals, the $500,000 cap binds first. Credit and debt load rarely bind on an investment line, because the 700 floor already screens that out.

Bank statements affect only the income side. Business bank accounts need a 680 minimum for the deposit analysis, but an investment line already floors at 700, so the deposit analysis is never the tightest constraint. Debt-to-income is qualified on the interest-only payment calculated on the maximum draw, not on what you actually borrow.

The same equity formula applies to every line. A CFPB explainer on home equity lines defines a HELOC as an open-end line you can borrow against repeatedly, and defines equity as home value minus what you owe.

Do Credit Unions Offer This on Rentals?

Some do, but the field is thin. Credit unions answer to a federal regulator with its own business-lending framework. The National Credit Union Administration (NCUA) treats a loan as a member business loan when the proceeds fund a business or investment property purpose. According to an NCUA legal opinion on business real estate loans, the exemption for a member’s primary residence does not extend to rentals. That is one reason some credit unions exclude non-owner-occupied properties or ration them.

Compare the lender types a landlord can approach.

Membership comes first at a credit union. You generally have to qualify for membership before the loan officer reviews anything. If you do ask, use the words investment property or non-owner-occupied, because calling it a home equity line routes you to the owner-occupant desk.

A broker changes the question. Across a wholesale network, programs differ on leverage, property types, and documentation. The right program for a given file depends on credit profile, equity, title, and how income is documented. A broker shops the file across several lenders instead of betting on one.

How Deposits Become Income for Landlords

Lenders read bank statements for consistent business deposits. Landlords with mixed accounts should expect closer scrutiny.

• Expect to provide twelve to 24 months of consecutive, complete statements, with every page included.
• Rent deposits that are separable from personal transfers.
• Explanations ready for large or unusual deposits.
• Security deposits held apart from operating income, where the account structure allows it.
• A business account for rental income, with a minimum 680 score for the deposit analysis.

Transfers between your own accounts get screened out. If you run an operating company, the expense factor reduces the deposits counted as income.

Title and Entity Issues

An investment-property line requires title in your individual name or an inter vivos revocable living trust. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title. If your rental is already deeded to an LLC, you need a vesting change or a different product.

That product is usually a DSCR cash-out refinance. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, and it works for entity-owned rentals. DSCR 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 full picture, see the complete DSCR loans guide.

Bank Statement HELOC vs. Rental Cash-Out

A line leaves a low-balance first mortgage in place. A cash-out replaces it. If you want to preserve the existing first mortgage and borrow modestly, a line may fit. If you want to borrow more, hold the rental in an LLC, or have thin personal income, the DSCR route usually fits better.

One caution on DSCR. It compares rent to the full payment: principal, interest, taxes, insurance, and any association dues. Clearing 1.00 does not mean positive cash flow, since repairs, vacancy, management, and capex sit outside the calculation. Select programs start at 1.00, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.

How the Line Works After Closing

On an investment property, the line runs a 5-year interest-only draw period, followed by a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing, and the cost floats during both phases and never converts to fixed. After closing, you can take later draws, with a $1,000 minimum in most states.

Lines of $500,000 or less ordinarily use an automated valuation, so a traditional appraisal is often not needed. You can still request a full appraisal.

Lenders can freeze or reduce a line. The CFPB explainer notes that a lender may restrict further draws if the property value falls significantly or your finances change. A line you planned to use as down-payment capital for your next purchase can shrink at the worst moment. If the capital has a specific job, funding it with a cash-out refinance is the more stable choice.

Other limits matter at scale. 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. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned properties are not eligible either. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condominiums, are eligible. The bank statement line is available in Lendmire’s 16 full-service states, which is narrower than the 41-market DSCR footprint.

Key Terms Defined

CLTV: combined loan-to-value, meaning the first mortgage plus the new line, divided by property value.

Draw period: the stretch when you can borrow against the line, here five years of interest-only payments on an investment line.

Expense factor: the share of business deposits a lender removes before treating the rest as income.

Vesting: how title to the property is held, such as an individual, trust, or LLC.

PITIA: principal, interest, taxes, insurance, and any association dues, the payment a DSCR loan compares to rent.

Questions to Ask Before You Apply

Whether you approach a credit union or a broker, ask these in order:

1. Do you lend on non-owner-occupied one-to-four-unit properties? 2. What maximum CLTV applies to an investment property, and is there a dollar cap? 3. Is there a limit on how many rentals I can have financed? 4. Do you accept 12 to 24 months of bank statements, and what expense factor do you apply? 5. Does title in a revocable trust work, or must it be my individual name? 6. Is the payment test run on the full line or only on the amount drawn?

If the first answer is no, move on. That single question saves the most time.

Common Mistakes

• Assuming statements mean light underwriting. Credit, debt load, equity, and the property are all still reviewed.
• Assuming higher credit buys higher leverage. On the investment tier, a 720 score reaches the same 70% as a 700.
• Asking for a home equity line without saying the property is a rental. That sends the file to the wrong desk.
• Treating a HELOC and a cash-out refinance as the same product. One is a revolving second lien, and the other replaces the first mortgage.
• Assuming the expense factor is always 50%. It is only an example.

Whether interest on a rental line is deductible is a tax question. Tax treatment varies; consult a qualified professional.
