How Much Can You Borrow on a Bank Statement HELOC to Purchase Investment Property?

The Quick Read: Usually less than the equity in your other properties might suggest, because on an investment property the ceiling in Lendmire’s network is 70% combined loan-to-value, capped at a $500,000 line, with a 700 minimum credit score, and the bank statements never raise that number since they only prove the income that qualifies you for the line. The line produces cash from equity in a property you already own. A separate DSCR loan then finances the purchase.

• Bank statements decide whether your income qualifies. Equity, CLTV, credit, and the dollar cap decide the size.
• Primary-residence lines reach higher, but only at a 720-or-better credit profile.
• The purchase lender decides whether the borrowed cash counts as your down payment.
• Clearing the DSCR test is not the same as positive cash flow, and the line payment sits outside that test.

How Does the Borrowing Math Work?

Your maximum line is property value times the allowed CLTV, minus every lien already on the property. CLTV adds up all loans secured by the property, including the full new line, and divides by value. NerdWallet explains that the limit depends on home value, the lender’s own cap, and what you still owe on the first mortgage.

Here is the math in percentages, so you can run it against your own property. Say the allowed CLTV is 70%, which is the ceiling on an investment property in Lendmire’s network.

• Low balance. Your first mortgage is 40% of value. You have 30 points of room.
• Moderate balance. Your first mortgage is 60% of value. You have 10 points of room.
• High balance. Your first mortgage is 70% of value. You have no room at all.

The same arithmetic works at any ceiling. Only the starting number changes.

Lenders test CLTV on the full line, not the amount you plan to draw. Taking only half the line does not halve the number the lender counts.

Which Limit Binds First?

Three limits can stop you, and whichever you hit first sets your number. Work through them in this order.

1. The percentage ceiling. On an investment property, 70% CLTV is the cap. Credit above 700 does not raise it. Both the 700 and 720 tiers reach the same 70%, so a stronger score buys eligibility, not leverage.

2. The dollar cap. Investment lines run from $25,000 up to $500,000. On higher-value properties with little debt, the $500,000 cap binds before the percentage does.

3. Debt-to-income (DTI). The maximum is 50%, and 45% for profiles from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you actually draw. That means a big line can fail on DTI even when the equity is there.

The ceiling also depends on the occupancy of the collateral. Which property you pledge changes the answer more than almost any other choice.

What Do Bank Statements Change?

Bank statements change how your income is documented. They do not change how big the line can be.

A bank statement HELOC is built for self-employed borrowers whose tax returns understate cash flow after write-offs. The lender reads deposits instead, commonly over a 12 to 24 month window. Transfers and non-income credits get stripped out. Business deposits typically get an expense factor, and the remainder is averaged across the window.

This still counts as documentation. Credit, a valuation, and DTI all get reviewed. A borrower is reviewed on documented income under the applicable program, subject to lender guidelines.

One practical detail helps here. Business bank accounts need a 680 minimum for the deposit analysis. Investment lines already floor at 700. So on an investment line, the bank statement analysis is never the binding constraint. Your credit score and equity are.

Limits by Property Use

Which property secures the line sets the ceiling. These are typical figures from select wholesale lenders in Lendmire’s network, subject to lender guidelines and full file review.

Read that table carefully. The 90% figure exists only at a 720-or-better credit profile. It does not apply to rentals. Lines above $500,000 are primary-residence only and need a full appraisal.

An investment line stays at $500,000 or less, so it normally runs on an automated valuation rather than a traditional appraisal. A borrower can still request a full appraisal.

Using your primary home usually produces more room than using a rental. It also puts your home at risk for a rental purchase. That is a real tradeoff, not a footnote.

Can the Cash Fund the Down Payment?

Yes, in most cases, but the purchase lender makes the call. Across the wholesale network, DSCR lenders commonly accept secured borrowing as a down-payment source, such as a home equity line or a cash-out refinance. They do not accept an unsecured personal loan or credit-card cash. Each lender sets its own rule on how much of the down payment can be borrowed, and reserves are the test most likely to exclude borrowed funds.

Here is how the DSCR purchase side looks. Most files land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700+ score. Credit floors run from 620 in parts of the network to around 660 on most programs. Reserves vary by lender, leverage, and loan size, and commonly sit near 6 months of PITIA (principal, interest, taxes, insurance, and HOA dues).

DSCR means debt service coverage ratio. It compares the property’s rent to its PITIA. Many 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.

On most DSCR purchase loans, the ratio reads the new property’s rent against its own payment. It does not read your HELOC payment. That is where investors get fooled.

Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. Your line payment sits outside it too, but it still comes out of your pocket. One rent check ends up carrying two obligations.

How Does the Line Behave After You Draw?

It behaves like a short-term tool, not permanent financing. The Consumer Financial Protection Bureau describes a draw period followed by a repayment period, and notes that payments are often significantly higher once repayment begins. It also says some plans require an initial draw or a minimum amount each time, and in some cases the whole balance comes due when repayment starts.

Typical draw periods across the broader market run 5 to 10 years, followed by a 20-year repayment period, according to Experian. In Lendmire’s network, an investment line runs one structure only: a 5-year interest-only draw followed by a 25-year fully amortizing repayment.

Three more mechanics matter:

• At least 75% of the line must be drawn at closing. You cannot open a large line and leave it untouched.
• The line floats and never converts to fixed. Your cost can change after you close.
• After closing, each additional draw has a minimum, typically $1,000 on the longer-runway structure.

Plan for the day the draw period ends. A line used as a down payment on a rental needs an exit: a payoff from a later refinance, from sale proceeds, or from steady paydown.

Who Cannot Use This Product?

Several borrowers are shut out before the math even starts. Check these first.

Vesting. The individual borrower or a revocable living trust must hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. This is the sharpest structural difference from a DSCR loan, subject to lender program eligibility on the DSCR side.

Property type. Single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.

Exposure. A borrower is limited to three lines. Combined exposure caps 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.

Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure seasons for 7 years, and a deed-in-lieu, pre-foreclosure, or short sale for 4 years.

Geography. Lendmire places this product in 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C. A property listed for sale, or listed within the past 60 days, is ineligible in several of those states.

Which Structure Fits Your Goal?

A HELOC is one of three ways to get a rental purchase funded. Each answers a different question.

A cash-out refinance on a standard rental tops out near 75% LTV across most of the network. A short-term rental cash-out is lower, at 70%. Either way, a cash-out replaces your first mortgage and creates a new payment on that property. A HELOC leaves the first mortgage alone, which matters when your existing loan is a good one. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

If your funds are already sitting in savings, a DSCR purchase with your own cash avoids the second payment entirely. A larger down payment lowers the monthly payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

Key Terms Defined

HELOC: A home equity line of credit, which lets you borrow against equity as needed during a draw period.

CLTV: Combined loan-to-value, which adds every lien on the property, including the full new line, and divides by value.

Bank statement income: A documentation method that reads deposits over a set window instead of tax returns.

Draw period: The stretch when you can borrow from the line, usually interest-only, before repayment starts.

DSCR: Debt service coverage ratio, which compares a rental’s income to its monthly PITIA.

Seasoning: The waiting period a lender wants between two events, such as buying a property and refinancing it.

What Should You Prepare?

Get the line approved before you shop for the rental. That order matters because the purchase lender will want to trace the funds.

• 12 to 24 months of personal or business statements
• A credit report no more than 90 days old at closing
• A clear title and vesting check on the collateral property
• Your first-mortgage balance and a rough value estimate
• A written record of each draw and where the cash went

Next Steps

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Lendmire is a broker that shops select wholesale lenders, and every figure here is subject to lender guidelines and a full file review, not a commitment to lend. Run the percentages on your own equity before you sign a purchase contract, because the dollar cap and the CLTV ceiling will decide how large a down payment this line can really supply.
