The Quick Read: A home equity line can fund a flip, but the line is secured by a property you already own, not by the flip. Which provider fits depends on the collateral’s occupancy, your credit profile, and how much combined debt the property can carry.
- On an investment property, the network’s ceiling is 70% combined loan-to-value (CLTV, meaning all debt against the property as a share of its value), with a 700 minimum score and a $500,000 maximum line.
- On a primary residence, the ceiling reaches 90% CLTV only at a 720 or better credit profile, up to $500,000.
- At least 75% of the line is drawn at closing, so interest runs on most of the balance from the start.
- Lendmire is a broker, so it shops multiple wholesale HELOC lenders instead of ranking one. Every figure is subject to lender guidelines and full file review.
A HELOC is often pitched as cheap, flexible capital. Parts of that are true. Other parts quietly change once the line is secured by your own house.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
This article walks through how the line works, how underwriting treats it, and where the usual advice breaks. It ends with the decision you actually face when a flip is on the table.
Why There Is No Ranked List of Providers
Lendmire does not rank or name HELOC providers. It is a mortgage broker that works with a network of wholesale HELOC lenders, and no single lender fits every borrower.
The right program for your situation depends on the collateral property, your credit, your existing debt, and how much leverage you need. A line that works for a primary residence with a strong score may not exist for an investment property with a thinner one.
A broker earns its keep by matching the file to the lender’s guidelines before an application goes in. That saves you from applying blind and collecting hard credit pulls from lenders whose rules you don’t meet.
One availability note matters here. Lendmire brokers DSCR financing in 41 markets, including Washington, D.C. Its home equity line offering covers only 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.
Key Terms Defined
HELOC: A home equity line of credit is a revolving loan secured by a property you own. You borrow against the equity, which is the property’s value minus what you owe.
Draw period: The stretch when you can borrow from the line. Payments during it are often interest-only.
Repayment period: The stretch after the draw ends, when you pay down principal and interest on a schedule.
Interest-only: A payment that covers only the interest, so the balance does not shrink.
Lien position: Your place in line to be repaid. A first-lien line sits behind no other mortgage, and a second-lien line sits behind an existing mortgage.
Vesting: How the property’s title is held. For these lines, title must sit in your own name or a revocable living trust.
DSCR: Debt service coverage ratio. It compares a rental’s income to its monthly housing payment, and it is the test used for rental-hold loans later here.
How a HELOC Works When the Money Goes to a Flip
A HELOC is an open-end line of credit that you can borrow against repeatedly, using home equity as collateral, according to the Consumer Financial Protection Bureau. You spend up to the limit during the draw period, then repay during the repayment period. The same page warns that falling behind could cost you the home.
Apply that to a flip and one fact reshapes the risk. The collateral is your primary home or another property you own. The flip is only where the money goes.
If the rehab runs long or the sale price disappoints, the lender still looks to the collateral property for repayment. Your house carries the flip’s risk.
Underwriting follows the same logic. The lender reviews you and the collateral property: your credit, your debt-to-income ratio, and the equity. It does not review the flip’s projected profit.
How Underwriting Treats the Line, Step by Step
Step 1: Pick the collateral. Your owner-occupied home is the usual choice. A second home or an existing rental can also work, under different limits.
Step 2: The lender sets the ceiling. The credit limit is a percentage of the property’s value, minus the liens already on it, as the CFPB’s HELOC booklet explains. On this network, the percentage depends on occupancy and credit tier.
Step 3: The lender checks your profile. The program floor is a 600 credit score on a primary residence. Debt-to-income is capped at 50%, or 45% for scores from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Step 4: The lender values the property. For lines at or below $500,000, the lender ordinarily runs an automated valuation with no traditional appraisal. A higher CLTV can trigger a secondary valuation. Every line above $500,000 needs a full appraisal, and you can request one at any size.
Step 5: You draw. At least 75% of the line is drawn at closing. Later draws carry a $1,000 minimum, except in Texas, where the minimum is $4,000. Pricing floats during both the draw and repayment periods and never converts to fixed.
Step 6: You exit. You sell the flip, pay down the line, and keep the collateral property.
Occupancy Changes Everything
The network’s leverage ceilings are tiered by occupancy. Here is the side-by-side.
| Collateral | Min. Score | Ceiling CLTV | Max line |
|---|---|---|---|
| Primary residence | 600 | 90% (720+ only) | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 640 | 90% (720+ only) | $500,000 |
| Investment property | 700 | 70% | $500,000 |
Read the 90% carefully. On a primary residence it applies only at a 720 or better profile, and only for lines up to $500,000. Lower credit tiers step down: a 640 score supports up to 80% CLTV on a primary residence, and a 620 supports 70%. A line above $500,000 is primary-residence only, caps at 75% CLTV, and needs a full appraisal.
Market surveys sometimes report investment-property lines at other leverage levels. On this network, the investment ceiling is 70% CLTV.
Run a quick example in percentages. Say an investment property carries a first mortgage equal to 50% of its value, and you hold a 700+ score. The 70% ceiling leaves room for a line of about 20% of the value. On a primary residence at 720+ with the first mortgage at 60% of value, the 90% ceiling leaves about 30% of value, subject to the $500,000 line limit.
When the equity is thin, the line may cover only part of a flip’s cost. In that case, the line can serve as the down payment while the balance comes from another source.
Structures and Variations
The wholesale network offers two draw structures on primary residences and second homes:
- A 3-year interest-only draw with a 17-year fully amortizing repayment.
- A 5-year interest-only draw with a 25-year fully amortizing repayment.
Investment property lines run only the 5-year draw and 25-year repayment structure. Tennessee shortens both structures. A line can sit in first or second lien position.
Property types matter too. Eligible collateral includes single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Where the General Rule Breaks
Your LLC cannot hold the collateral. The borrower must hold title individually or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts are not eligible. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead.
Exposure limits apply. A borrower is limited to three lines, with combined exposure caps that differ by program. An owner of more than 15 financed properties is not eligible.
Listing status can block a file. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA. Collateral you plan to sell soon is a problem in those states.
Texas primary residences are capped. A Texas primary residence is a homestead and caps at 80% combined loan-to-value. Texas second homes and investment properties follow their standard tables.
Derogatory history narrows options. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program: one program accepts a foreclosure after 7 years and a short sale or deed-in-lieu after 4, while the other declines it regardless of age.
The tax rules are narrower than many flippers assume. 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.
Selling the collateral ends the line. If you sell the home that secures the line, you generally must repay it in full right away. A lender can also reduce the line if the home’s value falls materially.
What Happens When the Flip Stalls
Say a rehab drags on. The sale price lands below plan, and the line stays open.
Because at least 75% of the line was drawn at closing, interest has been running on most of it the whole time. The payment is interest-only during the draw, but pricing floats, so the carrying cost can move against you. Nothing about the flip’s delay changes what the lender expects.
Your flip’s cost of carry now includes your personal housing risk. That is the real price of this structure.
A BiggerPockets thread on this question lands on the same practical point. The HELOC works best for a strong flip backed by solid comps, and it ties the two properties together until the line is repaid or refinanced out.
Stress-test before you sign. Ask whether you can carry the draw if the sale slips, and whether your own home stays safe if the flip loses money.
The Decision in Practice
A HELOC tends to fit when you hold meaningful equity and a strong credit profile. It fits best when the flip is short and the numbers have cushion.
It fits poorly when the collateral is thin on equity, the project timeline is uncertain, or your debt load is already heavy. It also fits poorly when you plan to keep the property and never intended to sell.
Compare the alternatives on structure, not slogans:
| Factor | HELOC | Rehab-purpose loan | DSCR hold loan |
|---|---|---|---|
| Collateral | Property you own | The flip itself | The rental |
| Underwritten on | You and the collateral | Deal and borrower | Rent vs. payment |
| Best use | Down payment, short flip | Purchase and rehab | Long-term rental |
| Risk sits on | Your other property | The flip | The rental |

If You Keep the Flip: The DSCR Exit
A flip can also become a rental. The usual path is to refinance into long-term investor financing and pay off the line.
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Across the wholesale network, a cash-out refinance tops out around 75% LTV on a standard rental, and about 6 months of seasoning is the common expectation. Most programs want a score around 660. Scores of 700 and up open the strongest leverage tiers, and a 620 floor exists in parts of the network.
Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Clearing 1.00 does not mean the property cash flows. DSCR compares rent only to the full housing payment. Repairs, vacancy, management, and utilities sit outside the calculation.
An LLC can hold the property under a DSCR loan, subject to lender program eligibility. That makes the DSCR exit a structural upgrade over the line. See the complete DSCR loans guide for how the program works end to end.

Frequently Asked Questions
Can I use a HELOC on a rental to fund a flip?
Yes, in some cases. On this network, an investment-property line needs a 700 minimum score and tops out at 70% CLTV and a $500,000 maximum line. It runs only the 5-year draw and 25-year repayment structure. Many borrowers find a primary residence offers more leverage, but your situation and the property determine which collateral works.
Does the flip secure the HELOC?
No. The collateral is the property you already own. The flip is where the money goes, so the risk sits on your other property if the project fails.
Can an LLC take out a HELOC?
No. A property deeded to an LLC needs a vesting change or a DSCR cash-out instead.
How much of the line do I have to draw?
At least 75% at closing on both draw structures. Later draws typically carry a $1,000 minimum, with Texas at $4,000. Interest-only payments start on the drawn balance, and pricing floats.
What if I want to keep the flip as a rental?
The typical exit is a refinance into a DSCR loan, which pays off the line. That loan is reviewed primarily on rental income covering the payment, subject to lender guidelines. Terms, leverage, and eligibility depend on the property and your profile.
