Best Investment Property HELOC Program to Fund a House Flip

The Quick Read: The best program depends on which property secures the line, how it is titled, and how long the flip will run. On an investment property, the network’s lines cap at 70% CLTV and $500,000, with a 700 credit minimum, and the line is underwritten on the borrower rather than the flip. A line is a down-payment and rehab layer, not a complete flip product, and every figure here is subject to lender guidelines and full file review.

• The line must be held in an individual’s name or a revocable living trust, never an LLC.
• A flip has no rent, so DSCR is the wrong tool during the rehab. It fits the hold or refinance stage after.
• Lendmire is a broker, not a lender, and the programs below are available only in its 16 full-service states.

What Does “Best” Actually Mean for a Flip Line?

No program is best for everyone. Fit comes from four things: collateral, vesting, credit, and the length of the project.

Lendmire is a mortgage broker. It works with a network of wholesale HELOC lenders and matches a scenario to the program that fits it. The lenders that write a given file depend on the property type, the credit profile, the leverage needed, and the documentation the borrower can provide. So the useful question is not which program wins. It is which program fits this property, this title, and this timeline.

Key Terms Defined

HELOC: An open-end line of credit secured by a property, which the borrower can draw against and repay repeatedly during a set period.

CLTV: Combined loan-to-value, which adds every lien on the property and divides by its value.

ARV: After-repair value, the estimated worth of the flip once the rehab is done.

Draw period: The stretch of the line when the borrower can pull funds, often with interest-only payments.

DSCR: Debt service coverage ratio, which compares a property’s rent to its full monthly housing obligation.

How Does a HELOC Fund a Flip?

A HELOC lets an investor borrow against equity already owned, then use the cash on a different property. The CFPB describes it as an open-end line of credit. You borrow up to a limit during a draw period, then move into a repayment period when you can no longer borrow. Falling behind can cost the home that secures the line.

For a flip, the cash usually goes to one of three places: the down payment on the purchase, the rehab budget, or holding costs while the project runs. Many investors use the line for the down payment and cover the rest with a separate short-term loan. That pairing keeps the line from carrying the whole project.

Equity is the part that trips people up. The line is sized from the collateral property’s value less what is already owed. A property with a large first mortgage has little room, no matter how strong the flip looks.

Which Property Secures the Line?

The collateral choice changes the program, the leverage, and the risk. Three setups come up on flip files.

The 90% figure exists only at a 720 or better credit profile, and it applies to primary and second-home lines, not to investment property. A primary residence in Texas is a homestead and caps at 80% combined loan-to-value.

Using the home as collateral means a failed flip becomes a lien problem on the house you live in. Benzinga notes that a line on an investment property works much like a home line but may price higher, and that missed payments put that property at risk of foreclosure. The line follows its collateral. The CFPB’s HELOC booklet says that if you sell the home securing the line, you generally must pay it off in full.

That is why the flip itself is a poor choice for collateral. Selling it triggers the payoff, and there is no equity to speak of until the rehab is done.

What Does the Investment-Property Line Look Like?

The investment-property line is a narrow, defined product. Across the network, these are the numbers on a file:

• Leverage: 70% CLTV. Both the 720 and 700 tiers reach the same ceiling, so credit above 700 buys eligibility, not extra leverage.
• Credit: 700 minimum. There is no tier beneath it.
• Line size: $25,000 up to $500,000. Anything larger is primary-residence only.
• Structure: a standalone line in first or second lien position, with a 5-year interest-only draw and a 25-year fully amortizing repayment.
• Draw at closing: at least 75% of the line is drawn when the loan closes.
• Pricing: floats through both the draw and repayment periods and never converts to fixed.
• Debt-to-income: 50% maximum, qualified on the interest-only payment calculated on the maximum draw.

Because an investment line caps at $500,000 and full appraisals begin only above that size, these lines sit in the automated-valuation lane. They commonly close with no traditional appraisal, though a higher CLTV may call for a second valuation. A borrower can also ask for a full appraisal. That matters on a rehabbed property, because an automated model can lag behind recent improvements. These ranges are typical, not guaranteed, and every file is reviewed individually.

The 75% draw at closing deserves attention. A line sounds flexible, but most of it is borrowed on day one. A flipper who wanted an undrawn reserve will find most of the line already in use. Plan the budget as if the draw is mostly spent.

Why Titling Is the Sharpest Edge Case

Title decides more flip files than any other single item. The network requires fee simple or leasehold title held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.

Many flippers hold rentals in an LLC for liability reasons. If the collateral is already deeded to one, the file needs a vesting change before it can move forward. The other route is a DSCR cash-out, which does accept entity vesting, subject to program terms. This is the biggest structural gap between a HELOC and a DSCR loan, and it surprises people who assume the two work the same way.

Other property edges:

• Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible.
• Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
• A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
• A borrower is limited to three lines, and one who owns more than 15 financed properties is not eligible.

Availability is also narrower than a DSCR footprint. These lines are offered only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.

How Is a Flip Line Underwritten?

The underwriting reads the borrower, not the project. The review looks at credit, equity, and debt-to-income. There is no analysis of the flip’s resale value or the rehab scope, which is the main contrast with a short-term lender focused on the property’s potential.

The credit review is specific:

• A 600 program floor exists on the network overall, but investment property floors at 700.
• The score model is a single bureau, keyed to the primary wage earner.
• The report can be no more than 90 days old at closing, and rescores are not allowed.
• A bankruptcy needs 4 years of seasoning from discharge or dismissal.
• Investment files follow a 7-year path after a foreclosure and a 4-year path after a deed-in-lieu, pre-foreclosure, or short sale.

Debt-to-income runs to 50% at most. A ratio above 45% needs a 680 minimum, which an investment borrower already clears. Bank-statement income is therefore never the binding limit on an investment line, because the 700 credit floor sits above the 680 minimum that business bank-account deposit analysis requires.

One more point from the draw rules. After closing, the minimum subsequent draw is $1,000 on the longer-runway structure, and $4,000 in Texas. The higher-leverage structure does not state a subsequent-draw minimum.

Flip Line vs. Other Funding Options

A HELOC is cheaper to use only when equity is already there. It is a layer, not a full stack. The comparison below shows where each tool fits.

A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A flip has no tenant, so there is no rent to measure while the work is underway. DSCR fits after the rehab, when the property is leased and the investor decides to hold it. The complete DSCR loans guide walks through how that stage works.

A common sequence runs like this: the line funds the down payment, a short-term loan covers the rest, the flip is either sold or leased, and a DSCR loan replaces the short-term debt if the property becomes a rental. Clearing a coverage ratio there is not the same as positive cash flow. The ratio compares rent to the full monthly housing obligation only. Repairs, vacancy, management, and utilities sit outside it.

What Happens When the Flip Runs Long?

A floating-price line puts the timeline at risk. Pricing moves through the draw and repayment periods and never fixes. A project that stretches out carries that variable cost longer, which can erode the margin. The line is interest-only for the first five years on an investment property, so the hold is rarely a cash-flow crunch. The real exposure is the balance that stays outstanding.

Three scenarios show how a long flip can go wrong.

Say a flip sells for less than the ARV the investor planned. The line still needs repaying from other funds, and the collateral property stays encumbered until it is paid off.

Consider a flip that stalls on permits. The line keeps accruing at a floating cost, and the investor holds two sets of carrying costs at once.

Picture an investor with thin equity. A 70% CLTV ceiling on an investment line leaves little room if a first mortgage is already large, and a low-CLTV file is where the line works best.

The CFPB notes that some plans require an initial draw at setup. On this network that initial draw is at least 75% of the line. Plan the payoff before the line is opened, not after.

How to Choose a Program for Your Situation

Work through these in order:

1. Identify the collateral. Primary home, second home, or an existing rental each carry different ceilings and risks.

2. Check the title. An LLC-held property needs a vesting change first, or a DSCR cash-out instead.

3. Confirm the credit tier. Investment needs 700. Primary and second-home lines can reach lower floors but need a 720 profile for the top ceiling.

4. Size the line against existing liens. Add the first mortgage to the requested line and test it against the CLTV ceiling.

5. Match the structure to the project. Decide how much of the line gets drawn at closing and how long the flip will realistically run.

6. Plan the exit. Know whether sale proceeds, a DSCR refinance, or another source repays the balance.

If equity is thin, a line is the wrong first move.
