Banks That Offer a HELOC to Fund a House Flip

The Quick Read: Most banks do not underwrite a HELOC for a flip at all. They underwrite a credit line on a home you already own, judged on your equity, your credit, and your debt-to-income ratio, and what you do with the draw is largely up to you, though each lender sets its own limits on investment use. Through its wholesale network of HELOC lenders, Lendmire (a mortgage broker, never the lender) places lines secured by a primary residence, a second home, or an existing rental. The best program for your situation depends on which property secures the line, your credit profile, and how much combined leverage you can carry.

• The flip does not qualify the line. Your equity, credit, and debt-to-income ratio do.
• Across this network, an investment-property line tops out at 70% combined loan-to-value (CLTV) with a 700 credit minimum, up to $500,000. Primary-residence lines reach 90% CLTV only at a 720-or-better credit profile.
• At least 75% of the line is drawn at closing, so you carry interest on most of it from day one.
• Selling the flip does not end the line, and lenders can reduce or freeze an undrawn balance.
• These lines are available in 16 full-service states, a narrower footprint than Lendmire’s DSCR lending.

How Does a Bank Actually Underwrite a Flip HELOC?

A bank treats a flip HELOC as an ordinary home equity line. The lender looks at the home that secures the line, your credit, and your debt load. It does not look at the flip’s projected profit, the rehab budget, or the rent the finished property might earn.

That surprises many new investors. They expect a lender to ask for the purchase contract and the scope of work. A home equity lender usually cares about three things instead:

1. Equity. How much the secured home is worth compared with what is already owed on it.

2. Credit. Your score and your history on every financed property.

3. Debt-to-income ratio (DTI). How your total monthly debts compare with your income, including the new line.

On this network, DTI tops out at 50%, and the line is qualified on the interest-only payment calculated on the maximum draw. That last detail matters. You are qualified as if you had borrowed the whole line, even if you plan to draw less.

Key Terms Defined

HELOC (home equity line of credit): A revolving credit line secured by a property you own. You borrow, repay, and borrow again up to a limit.

CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value.

Draw period: The stretch when you can borrow from the line and, on these programs, pay interest only.

Repayment period: The stretch after the draw period ends, when borrowing stops and the balance amortizes, meaning each payment includes principal.

Interest-only payment: A payment that covers interest on the balance but does not reduce the principal.

DSCR (debt service coverage ratio): Monthly rent divided by the full monthly payment on a rental, covering principal, interest, taxes, insurance, and any HOA dues.

Vesting: How title to the property is held, such as in your personal name, a trust, or an LLC.

The Process, Step by Step

Step 1: Pick the collateral. Most flippers borrow against the home they live in. Some borrow against a second home or an existing rental. Your choice sets the leverage ceiling, the credit minimum, and the maximum line size (see the table below).

Step 2: Run the equity test. The lender takes a percentage of the home’s value, subtracts what you owe, and the remainder is the most the line can be. The CFPB’s HELOC booklet describes this formula, using 75% of appraised value as its example. On this network, the percentage depends on occupancy and credit tier. An owner already carrying a heavy first mortgage may find little or no room.

Step 3: Document the personal side. Expect the lender to review a credit report no more than 90 days old at closing, your existing mortgage balances, income documentation for the DTI calculation, and your title vesting.

Step 4: Value the home. On lines at or below $500,000, the lender ordinarily runs an automated valuation instead of a traditional appraisal. A higher CLTV may call for a second valuation. You can also request a full appraisal.

Step 5: Draw and deploy. The money goes to the down payment, the purchase, or the rehab. Because at least 75% of the line is drawn at closing, plan the flip budget before you apply. Later draws on the 5-year structure carry a $1,000 minimum in most states.

Step 6: Exit and repay. You sell the flip, or you refinance it into long-term financing, and then pay down the line. The CFPB explains that during the draw period you can generally borrow up to your limit. After that, borrowing stops and repayment begins, often over 10 or 20 years.

The line does not close when the flip sells. It stays open until you pay it off or close it. Paying it down during the draw period usually restores borrowing room for the next project.

Which Property Secures the Line?

The property that secures the line sets the rules. This is where primary, second-home, and investment lines differ most, and where borrowers most often quote the wrong ceiling.

Read the table with care. The 90% figure on primary and second homes is a top-tier ceiling that requires a 720-or-better credit profile, and it applies to lines up to $500,000. Lower credit tiers step down from there. A primary-residence line above $500,000 requires a credit profile of 700 or better (720 on the 5-year draw structure), caps at 75% CLTV, and needs a full appraisal.

Market surveys sometimes report that lenders will lend up to 85% of home value on equity products. That is a broad-market statement. On this network’s investment lines the ceiling is 70% CLTV.

On primary residences and second homes, two draw structures exist. One has a 3-year interest-only draw followed by a 17-year repayment. The second is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Investment lines use the 5-year draw structure only. Pricing floats during both the draw and the repayment period and never converts to fixed.

Which Banks Say Yes?

Large retail banks, regional banks, credit unions, and online lenders all sell home equity lines. Whether any one of them lets you spend the draw on a flip, or lets you rent out the secured home, is set in that lender’s own line agreement. No reliable public count exists of how many banks allow flip use, so treat any such number with suspicion.

A mortgage broker changes the search. A single bank can only offer you its own product. Lendmire works with a multi-state network of wholesale HELOC lenders and matches the scenario to the program, based on:

• which property secures the line (primary, second home, or rental);
• your credit tier and housing history across every financed property;
• the line size you need and the combined leverage you can carry;
• how the property is titled.

The lenders that write your file depend on those four inputs, not on the flip itself. The best program for you may be a primary-residence line at one tier, or an investment-property line at the 70% ceiling. Lendmire does not lend, so the lender reviews eligibility and decides.

One practical point on proof of funds. If you also use a hard money lender, that lender may or may not count your home equity as liquidity. BiggerPockets practitioners note that some hard money lenders accept a HELOC as proof of funds and others want cash in the bank. Ask before you rely on it.

Worked Example: Reading the Equity Math

Picture an investor with a 720-plus credit profile who lives in a home with a first mortgage equal to 60% of its value. On a primary-residence line, 90% CLTV is the ceiling, and it applies only at a 720-or-better credit profile, for lines up to $500,000. The maximum new line is the gap between 60% and 90%, which is 30% of the home’s value, and the line size caps still apply on top of that.

Now suppose that investor wants the line to cover the down payment on a flip, with a short-term investor loan covering the rest of the purchase and the rehab. The HELOC payment lands on the investor’s personal DTI. The short-term loan carries its own payment and usually a personal guarantee. Both payments run at once until the flip sells.

Stack those two and the project can approach full leverage. BiggerPockets commenters make the same point: when a HELOC finances the down payment, you have no equity cushion in the property you just bought. A flip that sells slowly or below the budget then has no margin for error.

A stress test before drawing helps. Add carrying costs for a longer hold, a rehab overrun, and a lower sale price, and ask whether you can still repay the line from the sale or from other resources. If the answer is no, the flip is too thin for borrowed equity.

Where the General Rule Breaks

You cannot borrow against the flip before you own it. A line needs equity, and a property you have not bought yet has none. The flip can only be collateral for the line after purchase, and by then the purchase money has already been spent.

An existing rental can secure a line, with tighter terms. On this network, investment-property lines run from $25,000 to $500,000, cap at 70% CLTV, and need a 700 credit minimum. Practitioners on BiggerPockets describe these lines as pricier and more restrictive than hard money, and harder to get approved for. Treat that as practitioner opinion, not a rule.

An LLC cannot hold the collateral. Title must be in your personal name or in a revocable living trust. Corporations, partnerships, LLCs, and irrevocable, blind, or land trusts cannot hold title. A property 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.

The line can shrink. The CFPB booklet notes that lenders can reduce a credit line if the home’s value declines. Undrawn money is not committed money, which is a real problem when a rehab runs long. Draw what you need early, but remember that at least 75% is drawn at closing anyway.

The collateral is your home. Putting a primary residence behind a flip moves foreclosure risk from the project to your own house. If you cannot repay as scheduled, you could lose the home.

Some property types are out. On both wholesale programs, manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible as collateral. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible.

Exposure limits apply. A borrower is limited to three lines, and a borrower who owns more than 15 financed properties is not eligible. Combined exposure caps vary by program. Active flippers with several loans outstanding should count their lines before applying.

Tax treatment is a separate question. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

Choosing the Exit: Sale or Long-Term Loan

A HELOC fits a short hold. You draw, rehab, sell, and repay. It fits less well if the flip stalls, because the interest-only payments keep running on the drawn balance. When the draw period ends, the remaining balance moves into a 25-year (or, on some primary and second-home lines, 17-year) amortizing repayment, and the payment steps up.

Some flips become rentals instead. That is where a DSCR loan can replace the HELOC balance. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, so your personal DTI matters far less than it does on a HELOC. Our complete DSCR loans guide covers how those loans work in detail. These investor loans run across 40 states plus Washington, D.C., a total of 41 markets.

Here is how the numbers typically look across the network:

• Cash-out refinance: tops out around 75% LTV on most files, and about 6 months of seasoning is the common expectation.
• Purchase: most files land at 75% to 80% LTV, with select programs reaching 85% LTV at roughly a 700-plus score.
• Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
• Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700-plus unlocks the strongest leverage tiers.
• Entity: a DSCR loan can close in an LLC, subject to lender program eligibility.

Clearing 1.00 does not mean the property produces positive cash flow. DSCR compares rent to the monthly payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Every figure here is subject to lender guidelines and full file review.

Questions to Ask Before You Sign

Use this checklist with any lender or broker:

• Does the line agreement allow the draw to fund an investment purchase or a rehab?
• Does it restrict renting the secured home?
• What share of the line must be drawn at closing, and what is the minimum for later draws?
• How long is the draw period, and how long is the repayment period after it?
• Can the lender reduce or freeze the line, and under what conditions?
• What fees apply at closing, at renewal, and on early closure?
• What happens to the line when you sell the home that secures it?

Next Step

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. Programs change, every file is underwritten individually, and nothing here is a commitment to lend.

A flip funded on borrowed equity succeeds or fails on its exit, so decide how you will repay the line before you draw a dollar of it.
